1. Introduction to the Cyber Incident Response Plan (CIRP)
1.1 Purpose
The purpose of this plan is to provide operational structure, processes, and procedures to West
Dunbartonshire Council employees, so that they can effectively respond to incidents that may impact
the function and security of digital assets, information resources, and business operations.
Cyber-attacks can quickly escalate and become a significant business disruptor requiring both
business continuity and consequence management considerations. Whilst much of the CIRP will be
managed within the IT Services environment, early consideration should be given to engaging both
Business Continuity, Resilience Leads and Strategic Resilience Group (SRG) and/or the  Resilience
Group (RG) as appropriate, in order that the wider issues can be managed.
The CIRP will assist West Dunbartonshire Council in identifying, managing, investigating, and
remediating various types of cyber incidents. It describes the processes for initiating a response and
establishing the structure needed to ensure response execution. This CIRP will also reference
procedural documentation that provides operational-level details specific to handling the various
incident types.
The CIRP cannot anticipate and provide guidance for all potential incidents. Management and
incident responders should consider the current situation, business impact, and security needs of
West Dunbartonshire Council and balance those against the guidance and recommendations
provided by the CIRP.
Governance of cyber incident policies, procedures, and planning, is the responsibility of the ICT
Management team and the ICT Security Officer.
This plan is based on several recommended industry best practices including:
 The Standard of Good Practice for Information Security 20181
 Existing cyber incident response documentation provided by Scottish Public Sector
organisations
 ISO/IEC 27035: 2016 Information Security Incident Management2
1.2 Central Notification and Co-ordination Policy
All Scottish Public Sector organisations should comply with the Scottish Public Sector Cyber Incident
Central Notification and Co-ordination Policy as part of the Scottish Government Public Section
Action Plan (Appendix E and F) which outlines the policy and procedures for notifiable cyber incidents
impacting on Scotland’s public services.
The trigger for consideration of such notification is defined as incidents or attacks against Scottish
public sector network information systems which will:
 Have the potential to disrupt the continued operation of the organisation or delivery of public
services; and/or
 Carry a likelihood that other public, private or third sector organisations may experience a
similar attack, or that the incident could spread to those organisations; and/or

OFFICIAL
 Could have a negative impact on the reputation of the Scottish public sector or Scottish
Government; and/ or
 Carry the likelihood of Scottish Parliament or national media interest.
In such circumstances there is a requirement to notify the National Cyber Security Centre (NCSC),
Scottish Government Cyber Resilience Unit (SG CRU) and Scottish Government Resilience officials
for incident management and co-ordination purposes and Police Scotland for crime investigation
considerations. This reporting mechanism is intended to enable the appropriate levels of external
support to be considered that might not be immediately obvious to organisational security teams who
are focussed on dealing with the incident at hand.
1.3 Alignment to UK National Cyber incident Reporting Protocols
The CIRP acknowledges the National Cyber Incident Management Policy (NCIMP – this is a
restricted circulation policy) and the Scottish Public Sector Cyber Incident Central Notification and Co
-ordination Policy, that set out the process for managing cyber incidents that have a national impact in
both Scotland and the UK context. The NCIMP aligns with the Central Government Arrangements for
Responding to an Emergency: Concept of Operations (CONOPS). The NCSC is responsible for
officially ‘declaring’ a cyber incident that requires management and co-ordination at a UK level. For
context and information on the NCSC incident categorisation framework3 please see Appendix G.
1.4 Scope
An Information Security Incident is an incident that specifically impacts upon West Dunbartonshire
Council information assets, e.g., the loss, theft, damage, or unauthorised destruction of information;
or an item of IT equipment on which such information is stored. Information Security Incidents
typically involve a potential impact to the confidentiality or integrity of West Dunbartonshire Council
information. Events affecting the availability of West Dunbartonshire Council information are typically
handled as Information and Communication Technology (ICT) Service Incidents by ICT Service
Management processes in the first instance as such processes are focused on restoring service
availability to users as quickly as possible. Loss of service availability is likely to become a security
issue where it stems from a deliberate hostile act, or where change is required to avoid repetition.
A cyber incident is the subset of Information Security Incidents that affects digital data or ICT assets
and does not involve any hardcopy information. For example: a user account compromise, a network
intrusion, or a malware outbreak.
Cyber incident management is the process of handling all cyber incidents in a structured and
controlled way. This plan aims to ensure that:
 All cyber incidents are managed effectively
 A consistent approach is implemented to manage cyber incidents
 The damage caused by a cyber incident is minimised
 The likelihood of recurrence of the security incident is reduced by the review and
implementation of appropriate measures
The scope of this plan is limited to cyber incidents affecting the ICT services, electronic data and
associated digital assets within the control of West Dunbartonshire Council. For the purpose of this

plan, the following list of IT incidents will not be treated as cyber incidents and therefore are outside
the scope of this document:
 Software problems and technical failures not caused by malicious activity
 Unavailability of the ICT network and / or systems
 Performance problems with the corporate ICT network and / or systems
 Hardware problems and failures
2. Management Roles and Responsibilities
2.1 Cyber Incident Response Team (CIRT) & Crisis Management Team (or Strategic/
Resilience Group (SRG/RG))
Cyber incidents are managed (triage, containment, eradication, lessons identified and reporting) by
the CIRT. This team is responsible for analysing security breaches and taking any necessary
responsive measures and advising Senior Management and if stood up the SRG of key breaches and
the response developed. In most instances the CIRT will be informed of and brought together as a
team when relevant breaches/risks have been raised to the group after an assessment of risk has
been made by the ICT Manager.  It may be that a smaller team from within ICT Services will assess
and classify the incident prior to escalation to the CIRT which will likely involve wider non-ICT
employees. References to an Extended CIRT will relate to external parties invited as required.
The SRG may be stood up to deal with the strategic consequences and decisions that arise from the
CIRT incident management. Within West Dunbartonshire Council this team consists of the Chief
Executive, Chief Officers and HSCP Heads of Service.
The Core CIRT includes key operational employees necessary to identify and triage all cyber
incidents within West Dunbartonshire Council. This team will be chaired by the ICT Manager
supported by the following employees as required:
 Information Security Officer
 ICT Extended management team
 Other ICT officers with specialist knowledge as required
The CIRT will revert to the SRG or RG as determined by incident scope :
The CIRT may be extended (Extended CIRT) to incorporate external partners and agencies where
this is deemed appropriate in circumstances to add value to the management of the incident. This will
often be the case in more complex incidents that lead to escalation. This may include: Existing
strategic ICT partners and/or suppliers; 3rd party security specialists, Scottish Government, Police
Scotland, and/or the National Cyber Security Centre (NCSC).
2.2 RACI Matrix
Delegation, clarity, and accountability are crucial in dealing with cyber incidents that have escalated
to requiring a CIRT to be formed. The RACI matrix is a useful tool that assigns responsibility and
maps out tasks, milestones or key decisions involved in completing a project such as managing an
incident. It assigns which roles are Responsible for each action item, which personnel are

Page 7

OFFICIAL
Accountable, and, where appropriate, who needs to be Consulted or Informed. It is a very useful tool
in the context of developing a CIRP.
Responsible: Refers to those who do the work to complete the task.
Accountable: Designates the person who ultimately answer for the results of an activity, and who
delegates the work to the people who will execute it.
Consulted: Refers to those who should be heard on the related activity, and with whom there is two-
way communication.
Informed: Designates those who sought to be kept up to date on the progress of the activity, and with
whom there is just one-way communication.

3. Communications
3.1 Management Notification
The Core CIRT will keep the Council’s resilience lead, SRG/RG and associated third parties informed
of the details of all confirmed CRITICAL or HIGH severity cyber incidents via the appointed Single
Point of Contacts (SPoCs). Identified management and third parties include the following:
 Council Resilience lead
 Strategic and/or Resilience Groups
 Communication with regulatory authorities as required.
 Contact contracted security specialist third parties for assistance as required.
 Core respondents within the Scottish Public Sector Cyber Incident Central Notification & Co-
ordination Policy
 Resilience Partnership for early multi agency support and co-ordination arrangements.
3.2 Third Parties Notification
The Core CIRT will arrange via the DPO for notification to relevant third parties all confirmed
CRITICAL or HIGH severity cyber incidents where the incident has compromised their information,
such as payment card/ account data. This would also include situations where the third party has lost
data or the data has been compromised that relates to West Dunbartonshire Council and/or our
customers. Incidents that would need to be notified include:
 Loss of Personally Identifiable Information (PII), such as personal details including name,
address and telephone numbers of staff or customers- responsibility for potential reporting to
the ICO sits with the Council’s Data Protection Officer.
 Key logger or card skimmer device found
 DDoS attack where DNS need to be modified
 Contacting software vendors for modifications to applications to remove exploited
vulnerabilities
The Core CIRT will notify Cyber incidents requiring support from trusted third-party service providers
such as ISP, DNS management, Application Development and Penetration Testing where there is a
need to consult with them with regards supporting the management of the incident.
Following SRG being stood up, the Core CIRT will notify the relevant authorities of cyber incidents
that meet the requirements of the Scottish Public Sector Cyber Incident Central Notification and Co-
ordination Policy to:
 Police Scotland Cyber Unit, The National Cyber Security Centre, The Scottish Government
Cyber Resilience Unit.

OFFICIAL
Where incidents do not meet the thresholds of the above policy the Core CIRT will consider notifying
Cyber incidents to the NCSC and / Police Scotland and Scottish Government CRU where there is
value in improving the rich intelligence picture, other public sector bodies could take mitigation steps
or there is a crime worthy of investigation.

4.1 Step 1 – Prepare
The key to minimising the impact and quickly recovering from a cyber incident is in the planning and
preparation. A well-trained team that has access to a comprehensive up-to-date set of documentation
with a well-managed and monitored ICT estate will greatly improve the response times to a cyber
incident. Therefore, the following actions should be undertaken to enable a CIRT to function
effectively.
4.1.1 Required documentation
The documentation below must be comprehensive, easily accessible to those who require it and
contained in a central location, WDC utilise the cloud based Resilience Direct (RD) platform as a
central repository  and will retain hard copies in the Secure Resilience cabinet located on the 2nd floor
in the WDC Church street office.  In addition, a library of documents and plans are retained in the ICT
cloud based service desk software, Freshservice, and this will  soon be available from outside the
organisation.
 Cyber incident Response Plan (this document)
 Exercise in a box from NCSC and tactical workflows (Playbooks) for specific response actions
(under development)
 Inventory of digital assets (where they exist) The Qualys vulnerability management tool will be
used as a starting point, similarly, Education have the Gsuite management console which has
information on the Chromebook estate
 Network Diagrams
 Documentation of services, protocols, and ports allowed or links where this information
resides available via resilience direct (RD documentation is currently being reviewed)
 Inventory of approved operating systems and applications (Resilience Direct)
 Configuration standards for all systems
 Media inventory
 Detailed Forensic imaging procedures (provision via 3rd party is acceptable)
 Contact information for:
o Core IT CIRT members
o CIRT members (Appendix B)
o Crisis Reliance Management Team (CRMT) members (Appendix C)
o Third Party Support Providers (Appendix D)
Along with
System Logs where available
Change control for all systems as recorded in the Freshservice system
4.1.2 Preparation
Gather cyber threat intelligence to enable an understanding of the risks to the business and
infrastructure, knowledge of threat actors, their motivation and delivery methods. Threat intelligence
sources include:
 National Cyber Security Centre Threats reports
 Cyber Information Sharing Partnership (CiSP)

Page 11

11
OFFICIAL
 Open-source intelligence feeds, including security vendor assessments and security
newsfeeds and subscriptions
 Police
Other preparatory activities include:
 Routine review of the West Dunbartonshire Council security architecture to ensure a
comprehensive defensive structure is in place.
 Reviewing the organisations related policies e.g. Business Continuity policies.
4.1.3 Business As Usual information/processes which will assist in any future
incident response (Information available prior to any incident)
 Availability of known baselines (where available) for network, server, storage, and application
performance accounting for fluctuations in demand for known activities e.g., month end,
product launch etc.
 Automated alerting from all systems when their performance or other metrics falls outside the
acceptable tolerances
 Daily review of automated alerts and review of event logs where appropriate
 Access to Configuration Management type Databases, server database, device database,
Freshservice system.
 Backup and recovery processes for all systems and infrastructure
 Ensure all system clocks are synchronised with a trusted network time source
 Implement a cohesive patch management plan for all operating systems and third-party
applications
 Implement a functional vulnerability management program that identifies weaknesses in the
West Dunbartonshire Council environment that can be efficiently remediated
 Consider developing and maintaining partnerships with external third-parties for services
such as:
o Digital Forensics and other Incident Response services
o Regular Phishing simulations and exercises
o Credit protection for data breaches
o Citizen call centre for use during a data breach
o Crisis/reputation management
o Threat Intelligence
4.1.4 Training & Awareness
 Annual CIRT refresher on cyber incident response plan actions
 Security awareness training is given to all employees as part of the induction process with
annual refresher training. 
 Incident Response Training as part of the Civil Contingencies Service
 WDC maintains a record of all employee security training
4.1.5 Testing
West Dunbartonshire Council shall execute a Testing, Training, & Exercise (TTX) program to sustain
and refine the organisation’s ability to handle cyber incidents in accordance with the best practices
outlined in NIST Special Publication 800-84 Guide to Test, Training, and Exercise Programs for IT
Plans and Capabilities. Testing should include:

Page 12

12
OFFICIAL
 Annual penetration testing
 Annual internal testing of response plan / playbook, using simulated scenarios including:
o Ransomware
o Phishing (Every 2nd month)
o Distributed Denial of Service (DDoS)
o Data loss and theft
 Testing of Insider threat assessment
4.2 Step 2 & 3 – Identify and Report  
Any suspected or actual breach of information security policy or systems must be immediately
reported to the West Dunbartonshire Council ICT Service Desk by phone call, ICT Management by
email and/or text, ICT tech desk if on site at Church Street offices
If a suspected breach involves an employee relating to a sensitive issue, then a report can be made
directly to the Information Security Officer or to the Head of your service area
When reporting a cyber incident, it is important to collect as much information about the incident as
possible to enable the ICT service desk to give the incident an initial priority. Key information to be
captured should include:
 Contact information of the person reporting the incident and related parties
 Host names and IP addresses of suspected breached systems
 Nature of incident
 The potential impact of the incident along with which business area is likely to be affected by it
 Description of the activity and supporting evidence e.g., logs
 The asset tag/s of any device/s involved
Employees have a duty to report, log or respond to a notification of a cyber incident and failure to do
so would be considered a serious matter. Once the above information has been obtained, this will
allow the ICT Service Desk to assign a service desk priority to the incident, this will then determine
whether this is a security incident and needs to be referred to the CIRT and assigned a Cyber Incident
priority.

(including in breach of copyright).
12 Other harmful mode not
listed
Any event that is deemed to be a security event that falls within the
remit of the CIRT, but which does not fall into any of the above
categories.
Figure 3 – Incident Types
4.2.2 Data Classification
West Dunbartonshire Council possesses and stores information with varying levels of sensitivity. If a
cyber incident occurs, the response will depend on the type of data stored on the affected systems.
The CIRT should review the Councils Security Classification guidance. Figure 4 below provides a
high-level summary for data classifications.
Classification  Description 
OFFICIAL
Information which will be disclosed in response to a FOISA request, but which the
Council does not wish to publish pro-actively and would not want to release in an
uncontrolled and out of context manner
Information is restricted to employees or other contracted persons working on
behalf of the Council.  This may include information published on the Council’s
Intranet/Internet site and Council policies
OFFICIAL-SENSITIVE
Information which is shared on a need know basis which could have damaging
consequences (for individuals or the Council generally) if it were lost, stolen or
published in the media. Such information assets are conspicuously marked
OFFICIAL – SENSITIVE
Figure 4 – Data Classifications
4.2.3 Reporting to the ICO
In line with the GDPR (Article 33) the ICO must be informed within 72 hours of the organisation
becoming aware of a reportable data breach.
The DPO shall determine whether the incident amounts to a data breach which requires to be
reported to the ICO. Further guidance can be found at https://ico.org.uk/.
Where a decision to notify the ICO has been made, the following must be included as a minimum:
 Describe the nature of the personal data breach including where possible, the categories and
approximate number of data subjects concerned, and the categories and approximate
number of personal data records concerned.
 Communicate the name and contact details of the contact point where further information can
be obtained.
 Describe the likely consequences of the personal data breach.

Page 15

15
OFFICIAL
 Describe the measures taken or proposed to be taken to address the personal data breach,
including, where appropriate, measures to mitigate its possible adverse effects.
Where an incident under investigation meets the reporting requirements of the Scottish Public Sector
Cyber- Incident Central Notification and Co-ordination Policy, then core organisations including
Police Scotland and the NCSC will have been informed and able to offer incident management and
investigative support where appropriate. Where incidents fall below this policy position consideration
will be given to informing the NCSC and Police Scotland of the incident. This decision will be taken by
CIRT and reporting actions undertaken by the Information Security Officer.
4.3 Step 4 – Analyse and Investigate
The Core CIRT will perform an initial triage and classification of all suspected cyber incidents to
confirm the validity and the potential impact of the incident. The initial classification may be changed
once more detailed investigation has been carried out.  The initial classification should be retained so
that this can be used to help refine and improve the overall incident response process.
 All incidents (once declared as being a “Cyber Incident”) will be given an initial priority 1
(Critical) by the ICT Service Desk.
 All CIRT members will be contacted with details of the cyber incident.
Once an alert has been received, the Core CIRT must research the event, leveraging rapid data
collection and initial analysis (triage). The goal of the triage is to acquire enough pertinent preliminary
information to appropriately determine both the data classification involved and the estimated severity
of the incident. The initial Incident Responder (initial entity to receive the alert or be assigned the
alert) shall conduct an initial assessment and provide a data classification and a preliminary incident
severity to the Incident manager. The Core CIRT should appropriately note and/or close out incidents
involving false-positives according to the appropriate incident-tracking procedures. Where a
confirmed incident meets the severity score is determined as high or critical, it must be escalated to
the CIRT and the Chief Officer People & Technology, as the Council Resilience Lead, alerted.
4.3.1 Cyber Incident Severity Assessment
Incident severity as annotated in Figure 4 is guided by the consideration of two separate
components: “Type of Threat” and “System/Information Criticality.”
4.3.1.1 Types of Threat
The following is an explicit description of these threats in descending order of criticality:
Types of Threat  Description 
Threat Level 1
Human-Controlled Root-Level Compromise
- Unauthorised external personnel (cyber intrusion).
- Partner organisation exceeding authority.
- Internal personnel exceeding authority.
Close-Access Breach (physical penetration of a site)
- Rogue wireless access point.
- Router re-direct.
Threat Level 2
Human-Controlled User-Level Compromise
- Unauthorised external personnel (cyber intrusion).
- Partner organisation exceeding authority.
- Internal employee exceeding authority.

Page 16

OFFICIAL
Threat Level 3 Automated (malware-controlled) Root-Level Compromise
Threat Level 4 Automated (malware-controlled) User-Level Compromise
Threat Level 5 Denial of Service
Threat Level 6 Focused Scanning or Unmanaged Malware
4.3.1.2 System/Information Criticality
The criticality of systems and information that is potentially at risk is the second component to
guiding the assessment of the severity of an incident. The following is an explicit description of
these system/information criticalities in descending order of importance:
System/Information
Criticality 
Description 
Criticality Level 1 Enterprise-Wide Network Resources (Revenue-Generating Services, Routers,
Switches, DNS, Proxies Firewall etc.).
Criticality Level 2 High Criticality Information – Confidential Information (Intellectual Property, PII,
PHI etc.).
Criticality Level 3 High Criticality Systems (Active Directory, Exchange, Web Services etc.).
Criticality Level 4 Sensitive Information – Restricted Information (Sensitive Corporate Information,
non-PII, Financial Transaction Information etc.).
Criticality Level 5 Non-Critical Multi-Use Systems (File Servers, SharePoint etc.).
Criticality Level 6 Individual Systems and Non-Sensitive Information.

4.3.1.4 Incident Severity Guidance
The following guidelines are for categorising the severity of an incident based on the known facts of
the incident and the subsequent impact to the organisation. The prioritisation of how to resource the
response to the incident is a critical decision point in the process. The CIRT should handle incidents
based upon the risk they pose to West Dunbartonshire Council, its information, and computing
environment. This section describes the severity levels and the structure used to determine this.
The Core CIRT will normally handle severity levels assessed as LOW and MEDIUM, whilst the CIRT
will normally handle severity cases assessed as HIGH or CRITICAL 
Severity
Level
Impact to West Dunbartonshire Council Incident Response Characteristics
CRITICAL
Highest severity level. Impacts are
extraordinary and potentially catastrophic to
the proper conduct of Council business, loss
of public trust, and/or impact on Council
operations or personnel. Impacts that are
indicators of this degree of severity are:
 Threat to life or physical safety of the
public, customer, or Council
personnel.
 Significant destruction of ICT
systems/applications.
 Significant destruction of corporate
capabilities.
 Significant disruption of Council
business operations over a sustained
period of time.
 Massive loss of confidential
information. Significant loss of public
confidence.
 Dramatic reputational damage.
 Risk of financial loss (generally more
than £500,000).
This level requires immediate and continual
response actions from the CIRT and must
include as a first step, notifying the Chief
Officer of People and Technology. An incident
of this severity has the most significant impact
on Council operations and involves an
extensive, persistent, and usually very
sophisticated attack that is difficult to contain,
control, or counteract. This level of severity
will trigger the Scottish Public Sector Cyber
Incident Central Notification and Co-
ordination Policy.
Indicators of this are:
 Senior council leadership will have an
immediate and ongoing interest in the
incident, the investigation, and the
eventual recovery from the incident.
 Major external support from multiple
organisations would be engaged.
 Would likely involve law enforcement.
 Would likely involve multiple levels of
regulatory or compliance reporting.
 Would likely involve engagement by
multiple media outlets.
HIGH
Impacts are substantial to the proper conduct
of Council business, loss of public trust,
and/or impact on Council operations or
personnel. Impacts that are indicators of this
degree of severity are:
 Impactful destruction of some ICT
systems/applications.
 Impactful destruction of some
corporate capabilities.
 Substantial disruption of Council
business operations over a sustained
period of time.
 Substantial loss of confidential
information.
 Substantial loss of restricted
information.
 Substantial loss of public confidence.
This level requires immediate response from
the Core CIRT and must include as a first
step, notifying the Chief Officer of People
and Technology. The Extended CIRT must
also be notified. Most of the Extended CIRT
will likely be engaged at some point of the
incident response effort. This level may
involve extended work hours, to include
weekends, or could involve 24/7 response
activities. An incident of this severity has a
real and negative impact on Council
operations and involves a persistent or
sophisticated attack that requires substantial
resources to contain, control, or counteract.
This level of severity will trigger the Scottish
Public Sector Cyber Incident Central
Notification and Co-ordination Policy.
Indicators of this are:

Page 18

18
OFFICIAL
 Substantial reputational damage.
 Risk of financial loss (generally
between £100,000 and £500,000).
 Senior council leadership will have
an interest in the outcome of the
incident, the investigation, and the
eventual recovery from the incident.
 External support from multiple
organisations will likely be needed to
resolve.
 Would likely involve law
enforcement.
 Would likely involve some level of
regulatory or compliance reporting.
 Would likely involve engagement by
some media outlets.
MEDIUM
Impacts are moderate to the proper conduct
of Council business, and/or impact on Council
operations or personnel. Impacts that are
indicators of this degree severity are:
 Moderate disruption of Council
business operations over a sustained
period of time.
 Multiple sites or multiple business
units affected by the incident.
 Moderate loss or manipulation of
restricted information.
 Limited loss of public confidence.
 Limited reputational damage.
 Risk of financial loss (generally
between £25 and £100,000).
This level requires notification to the Council
CIRT. Several or most Council CIRT
members will be engaged in some aspect of
the response effort. The Extended CIRT
must also be notified. Selected Extended
CIRT members may be engaged at some
point of the incident response effort. This
level may involve extended work hours
initially, and will revert to a normal working
schedule once initially contained. An incident
of this severity has some impact on Council
operations and involves an attack that
requires an organised response to contain,
control, or counteract. This level of severity
will trigger the Scottish Public Sector Cyber
Incident Central Notification and Co-
ordination Policy.
Indicators of this are:
 External support may be needed,
and will be engaged as needed.
 May involve law enforcement.
 May involve some limited level of
regulatory or compliance reporting.
 Would likely not involve media
outlets.

Page 19

19
OFFICIAL
LOW
Impacts are greatly limited to the proper
conduct of Council business, and/or impact
on Council operations or personnel. Impacts
that are indicators of this degree severity are:
 Limited or no disruption of Council
business operations.
 One site or business unit affected by
the incident.
 Limited or no unauthorised access to
restricted information.
 No impact to public confidence.
 No impact to reputation.
 Risk of financial loss (Under
£25,000).
This level requires handling by a cyber or
incident response team member (Core CIRT)
and some Extended CIRT members may be
notified if deemed necessary. This level of
response is conducted during normal
working hours. An incident of this severity
has limited or no impact on Council
operations.
Indicators of this are:
 External support is generally not
needed.
 Law enforcement is generally not
engaged.
 Regulatory reporting is not
warranted.
 Would likely not involve media
outlets.

4.4 Step 5 – Containment
The CIRT or Core CIRT will take actions to contain and isolate the incident from the council network;
this may include the following:
 Isolating a system from the network
 Removing users access privileges
 Stopping services running
 Isolating connections to external partner’s networks to prevent spread to other organisations
 Identifying systems and services affected including details of:
o Host names,
o IP addresses,

Page 20

OFFICIAL
o MAC addresses,
o Active services,
o Locations
 Identifying times and source IP addresses of the attack including the following details
o Host names,
o IP addresses,
o MAC addresses,
o Protocols,
o Locations,
o Time,
o User accounts used
 If required contact specialist external support services to assist in the containment and
evidence gathering.
Details of handling procedures for specific attacks, including DDoS, Hacking, Suspicious Activity
(virus or malware, loss, or theft of data) will be detailed in the cyber playbooks (currently under
development)
Handling procedures for forensic evidence
 Maintain the state of the affected system (i.e., do not power off)
 Identify all potential sources of available evidence which may include:
o Storage media (HDD, DVD, USB, Tape)
o Live data (RAM, IM, network connections, encrypted files, and folders)
o Application data (temporary files and folders, browser history, email, images, swap
file, hibernation files)
o Servers (active directory, email, internet server, web server, encryption key
distribution, authentication servers);
o Logs (event, traffic, AV, software)
o Mobile phones (call history, contacts, emails, photos, videos, SMS, calendars,
locations)
o Sat Nav (journeys, locations)
o Electronic Files (documents, databases, spread sheets, PDFs, presentations)
o Hard files (printed copies, bills, invoices, receipts, notes, diaries)
o Meta data (dates, times, authors, accessed, created)
 Log all actions taken including:
o Name, date, and time of the person collecting the evidence
o How the evidence was collected, preserved, duplicated, analysed and stored
o If possible, have a witness to the process of the forensic evidence being taken.
o Secure system logs to prevent them being overwritten or deleted until the security
incident has been closed.
o If relevant, undertake forensic copies from computer memory to a file, and take a back
-up of the file.
o If relevant, take a forensic image (copy) of the computer hard drive(s), which will be
used for further analysis, to ensure that the evidence on the original system is
unharmed.
o Forensic evidence of a breach or suspected breach must be secured within 24 hours.
o Forensic evidence must only be gathered by trained personnel or specialist third
parties
o Untrained employees must not attempt to gather forensic evidence, (ICT employees
use post titles please and above will be assigned this task)

Page 21

OFFICIAL
A forensic imaging guide has been provided within Section 5. Appendix A for the purpose of
forensically preserving data.
*If in any doubt advice should be sought from Police Scotland specialists on handling
evidence.
4.5 Step 6 – Eradicate 
The objective of the eradicate step is to:
 Correct the incident by addressing its symptoms (e.g., healing malware infections or
correcting access control lists).
 Prevent its immediate reoccurrence by addressing its root cause. For example: changing
networking rulesets, moving the target host to a different network segment and/or IP address,
or constraining access to the target data to the minimum possible subset of users.
 Cyber Incident Playbooks provide details of eradication considerations for specific attacks
and should be referred to as appropriate
4.6 Step 7 – Recovery
Actions can be taken to restore services back to the pre-incident state once the CIRT or Core IT CIRT
confirm the remediation actions have been successful. However careful monitoring of the estate
should be taken to ensure any vulnerabilities have been successfully closed. The recovery actions
will include the following:
 Ensure that the impacted services are accessible again
 Ensure performance is in line with known (pre-attack) baseline
 Switch back traffic to the original network
 Restart stopped services
 Continue to monitor the performance/activities of the affected systems
 Confirm application behaviour is as expected
 Conduct vulnerability scan if deemed appropriate
4.7 Step 8 & 9 – Reporting and Lessons Identified
All cyber incidents will have a cyber incident report created. Cyber incidents will be fully reported and
reviewed within 5 days of the incident resolution.  Summary reports of all incidents will be reviewed at
the next ICT Steering board/Resilience meeting whose members will decide on actions to take
forward from the cyber incident report.
A cyber incident review is important so the business and CIRT can improve the systems and
procedures to reduce the impact of future cyber incidents.
Where external partners have been involved in the incident management process, consideration
should be given to their involvement in the post incident debrief (which will form the lessons
identified). Where appropriate the Resilience Lead from the Civil Contingencies Service will be tasked
with sharing the lessons identified with the wider Resilience Partnerships through the Local and
Regional Partnership structures.
Details to be captured in a cyber incident report include:

Page 22

OFFICIAL
Following the publication of a given Incident Report, the Information Security Officer will:
 Seek recipient feedback in relation to the incident report
 Confirm the viability of each security control change/addition recommended in the incident
report
 Identify a proposed action owner and action target date for delivering each proposed
recommendation
 Identify the proposed funding route for each proposed recommendation that requires financial
expenditure
 Seek the ICT Managers endorsement of the proposed actions and associated funding routes
 Seek the action owner’s acceptance of the relevant actions and target dates
 Review, at not less than monthly intervals, progress with each action with each action owner
 Notify the ICT Manager of any action at risk of not being delivered prior to its target date
 Consider sharing the lessons identified with appropriate external partners, including but not
limited to Police Scotland, Scottish Government (CRU and lead Policy team), Resilience
Partnerships, SGoRR, ScoRDS and NCSC

5. Appendix A – Forensic Imaging Guide
The steps listed below are a guide to assist in the capture of forensic images. Forensic evidence must only be
gathered by trained personnel. Failure to follow the correct procedure when creating a forensic image can result
in the image being inadmissible as evidence
 If a forensic bridge/write blocker is available, remove the HDD from the machine and attach it to the
write blocker which in turn is connected to an imaging machine. Proceed to take a forensic image using
forensic imaging software which should be installed on the imaging machine and refer to the official
user guide if required
 If a forensic bridge is unavailable or it is impractical to remove the HDD from the machine then boot the
machine to a live Linux distribution, such as Raptor v3.0. Ensure that the boot options are known for that
particular machine and that the BIOS is configured to allow booting from USB or disc. To help ensure
Windows does not boot if the live boot is missed, be prepared to disconnect from the power immediately
(always remove the battery from laptops)
 Once successfully booted, the imaging wizard should automatically launch. Attach a destination drive
where the forensic image is to be copied to and proceed to image using the wizard and refer to the
official Raptor user guide if required
 For both forensic imaging software and Raptor, ensure the verification option is checked and hash
values produced (see image on next page)
 Enter the machine’s BIOS settings and record (take photo) as a minimum of the system clock settings
 For cases involving theft, fraud, computer misuse, unauthorised access and other cases involving
where the user is under investigation, check optical drives for discs, USB ports for other media which
should be labelled, placed in an evidence bag and placed in locked storage pending an investigation.
Do NOT browse these devices live
 If unable to capture a forensic image using the provided tools secure the device and seek advice from
Head of Digital & Community Safety as soon as practically possible as third parties may need to be
informed
 Do NOT boot the machine and perform a live analysis unless all other methods have been exhausted
and advice sought from the Head of Digital & Community Safety
 If the infected machine is remote, instruct the user accordingly:
o For malware, remove from the network. If forensic imaging software is available instruct the
user how to image RAM and hard drive, disconnect power and return the machine and
RAM/drive image to IT for further imaging and analysis
o For other types of investigation, such as misuse, inform a line manager to disconnect the power
and seize the machine for return to IT, ensuring all actions have been recorded and that no one
interferes with the evidence
If the suspected user(s) is no longer an employee and the machine is not in use, consider seizing and place in
an evidence bag after a forensic image has been captured, record all details and place in locked storage.
If the machine needs to be re-introduced into the business (i.e. issued to another user) the HDD should be
removed and placed in an evidence bag, then a new HDD placed in the machine ready for re-issue. If not then
the HDD must be securely erased rather than simply formatting and re-building with the corporate image.
If the machine is currently in use by another user, capture a forensic image (RAM not required) and record
details of when the new user came into possession of the machine.
Virtual servers – Forensic image is not required, but obtain a snapshot or clone (VMSN, VMDK) for investigation
and reset to last known good state

9. Appendix F – Notifiable Reporting Form
First point of notification should always be via Chief Officer People and Technology
and the SIRO and/or CEO, thereafter;
Notifiable Scottish Public Sector Cyber Incidents are defined as incidents or attacks against Scottish public
sector network information systems which:
have the potential to disrupt the continued operation of the organisation or delivery of public services;
and/or
carry a likelihood that other public, private or third sector organisations may experience a similar attack,
or that the incident could spread to those organisations; and/or
could have a negative impact on the reputation of the Scottish public sector or Scottish Government;
and/or
carry the likelihood of Scottish Parliament or national media interest.
Scottish public sector organisations who are impacted by notifiable cyber incidents should complete the
notifiable cyber incident reporting form below as early as possible and, if email services are available, send the
completed form simultaneously to the following addresses in addition to those relevant to your own
organisational requirements:
The National Cyber Security Centre (NCSC): Incidents@ncsc.gov.uk
The Scottish Government Cyber Resilience Unit (CRU): cyberresilience@gov.scot
Police Scotland: C3DivisionServiceOverview@scotland.pnn.police.uk
SGOR: SGORRInformation@gov.scot
These services are available 24 hours a day, 7 days a week, and can be contacted at any time in the event of a
notifiable cyber incident. The ‘follow up’ numbers are as follows:
The National Cyber Security Centre (NCSC): 03000 200 973
