Introduction
Technology risks including information security, cyber security and data privacy are all key considerations for licensed firms and persons (“Firms”) regulated by the Guernsey Financial Services Commission (“the Commission”) and should be considered by other interested parties. The Commission applies a pragmatic, risk-based approach to regulating the Bailiwick’s financial services sector, and this is reflected in the Cyber Security Rules, 2020 (“the Rules”). As with other material risks, all licensed institutions are required to have robust policies, procedures and controls in place to identify, assess and manage cyber security risks on an on-going basis consistent with the minimum licensing requirements. The Rules focus on five core principles outlined in a number of international cyber security frameworks; Identify, Protect, Detect, Respond and Recover. The Commission recognises that there is no “one size fits all” approach to addressing cyber risks with specific business circumstances varying greatly from Firm to Firm. The following guidance provides Boards1 with examples of how a Firm may satisfy the requirements laid out in the Rules. Not all of the examples outlined in this guidance will be relevant to all Firms and it remains the responsibility of the Board to ensure that the Firm complies with the Rules. This guidance may also be used by non licensed firms such as Prescribed Businesses or Non-Regulated Financial Services Business. In addition to the below Guidance the Commission recommends that Firms consider the resources made available on the UK Government National Cyber Security Centre website www.ncsc.gov.uk

1 Throughout this guidance the term ‘Boards’ is used to refer to any group or individual who would hold a comparative position, to the Board, in a Firm. The Cyber Security Rules, 2020 are set out in red text boxes.

Application and Operation
Periodic Review
Depending on the size, nature and complexity of a Firm, the Board should decide on the frequency of periodic reviews. The Commission would not expect periodic reviews to take place any less frequently than every 24 months.
1.1 Application and operation
(1) These Rules have direct application to all licensees who are licensed under the Regulatory Laws. (2) The Board of Directors, or equivalent, is responsible for ensuring that these Rules are followed. (3) All licensees must be able to provide evidence, to the Commission on request, that these Rules have been considered and implemented in accordance with the size, nature and complexity of the licensee’s business. (4) The licensee must, taking into consideration the size, nature and complexity of its business, have in place appropriate policies, procedures and controls to mitigate the risk posed by cyber security events. Any policies, procedures and controls adopted, by the licensee, must reflect these Rules and take into consideration any guidance issued by the Commission. (5) All relevant measures adopted, by the licensee in order to comply with these Rules, must be reviewed – (a) in response to a trigger event; (b) following an identified cyber security event; or (c) at least periodically and must be recorded by the licensee. (6) The Commission may in its absolute discretion, by written notice to a licensee, exclude or modify the application of any provision of these Rules if the licensee satisfies the Commission that such a derogation does not prejudice the interests of the clients of the licensee or the reputation of the Bailiwick.

Identification of Assets and Risks
Assets and Data
A Firm should ensure it is able to identify the assets and data it holds and assess the damage, to its business, if it lost access to those assets or if the data it holds were to suffer a breach of confidentiality, integrity or availability. These assets should not be limited to traditional IT assets and should include systems, people and data assets. When considering the requirement to identify assets, in line with 2.1 of the Rules, Firms should consider the materiality and the possible underlying risks associated with that asset. All assets should be considered through a cyber security lens but not all assets will require bespoke or in depth analysis. Without knowing what you have to protect you cannot determine the appropriate controls to protect it. This assessment of cyber risks could be a standalone document or could be part of a pre-existing risk assessment document. Risks The Commission expects that the Board of all licensed Firms, or the relevant board committee, will have evaluated the Cyber Risks associated with the assets that it has identified and reviewed the impact that a cyber security event would have on the integrity, availability and confidentiality of those assets. Understanding the risks associated with the assets held will enable Firms to judge the appropriate level of controls and mitigants that are needed.
2.1 Risk Assessment of Cyber Vulnerabilities
(1) The licensee must ensure that it has taken appropriate steps to identify all of its material assets and carried out an assessment of significant associated cyber risks.
PART 2 - IDENTIFY
2.2 Risk Assessment of Cyber Vulnerabilities
(2) The licensee must ensure that it has taken appropriate steps to identify all of its assets and carried out an assessment of all associated cyber risks.
PART 2 - IDENTIFY
2.3 Risk Assessment of Cyber Vulnerabilities
(3) The licensee must ensure that it has taken appropriate steps to identify all of its assets and carried out an assessment of all associated cyber risks.
PART 2 - IDENTIFY
2.4 Risk Assessment of Cyber Vulnerabilities
(4) The licensee must ensure that it has taken appropriate steps to identify all of its assets and carried out an assessment of all associated cyber risks.

Protection and Detection
Policy and Controls
Following the identification and evaluation of cyber risks, Firms are expected to put in place processes, procedures and controls that are appropriate for the size, nature and complexity of their businesses and the risks faced. These controls and policies should be used to fulfil the Protect and Detect principles outlined in the Rules including the requirement to continue to deliver critical infrastructure where possible. A Firm should document how it has assessed the appropriateness of these controls, and its approach to mitigation, for the size and complexity of its business. Controls can broadly be categorised under the following headings:
1- Technical Controls
2- People Controls
3- Administrative Policy and Governance Controls
3.1 Protecting IT Services
(1) The licensee must ensure that it has the appropriate policies and controls in place to mitigate the risks it has identified and to ensure the delivery of critical infrastructure during and following a cyber security event. These policies and controls should include but are not limited to – (a) having appropriate cyber security software in place; (b) ensuring that IT system updates, from infrastructure and software providers, are implemented in a timely manner; (c) the provision of employee training to enable the recognition of possible cyber security events; (d) having policies in place to ensure that all users are aware of their impact on cyber security.
PART 3 – PROTECT
3.2 Protecting IT Services
(2) The licensee must ensure that it has the appropriate safeguards in place to mitigate the risks it has identified and to ensure the delivery of critical infrastructure during and following a cyber security event. These safeguards should include but are not limited to – (e) having appropriate cyber security software in place; (f) ensuring that IT system updates, from infrastructure and software providers, are implemented in a timely manner; (g) the provision of employee training to enable the recognition of possible cyber security events; (h) having policies in place to ensure that all users are aware of their impact on cyber security.

1. Technical Controls
   Technical Controls are procedures and controls that result in security measures executed or controlled through computer systems. They offer automated protection against misuse, unauthorised access to valuable information, facilitate security violation detection and support requirements of security related to data and application. The variety of Technical Controls available is vast and not all Technical Controls will be suitable to all Firms. Each Firm should consider which controls are suitable to their circumstances and should document these decisions. Technical Controls include, but are not limited to; Network monitoring tools Network monitoring tools enable Firms to monitor their networks and to detect security related events. Early identification of events can result in reducing damage and disruption. Vulnerability management. Vulnerability Management is the process of identifying, evaluating, treating, and reporting on security vulnerabilities in systems and the software that runs on them. Vulnerability management tools can include scheduled penetration tests and the use of automated system scanning tools. Patch Management Patch management is the process that helps acquire, test and install patches (code changes) on existing applications and software tools on a computer, enabling systems to stay updated. All security patches should be reviewed not just those that are flagged as critical or high. Lower rated vulnerabilities are used in vast numbers of attacks partly because some Firms don’t prioritise patching them so remain exposed for longer. 2 Factor Authentication (2FA)/Multi Factor Authentication (MFA) Firms should consider activating 2FA or MFA on any account accessed over the internet. 2FA or MFA adds an extra layer of security to every online platform accessed. The first layer is generally a combination of a username and password. The second layer is a further requirement to authenticate your identity; traditionally a code or token that has been sent to your email or generated by an application on a device. Adding the additional layer in the process to authenticate your identity makes it harder for an attacker to access your data. 2FA/MFA is a simple and cost effective measure to increase security of access to online systems. Email protection tools (phishing) Successful phishing attacks are one of the most common causes of cyber security breaches. The risks from phishing are extremely difficult to completely mitigate using technical controls. However, Firms can benefit from a technical solution in filtering out a lot of phishing emails, spam, spear-phishing and other email based threats and should consider the appropriateness of these tools. Firms should consider how it can increase employee awareness of phishing threats. Antimalware Antivirus or antimalware controls are universally used, however, older or lower cost antivirus solutions can depend on outdated signature based rules that are susceptible to more modern

malware or viruses. Antivirus or antimalware programmes should be reviewed regularly to ensure they are fit for purpose and able to detect newer threats and configuration settings reviewed to ensure that the antivirus or antimalware programmes are delivering the expected level of protection. Mobile Device Management Firms should give consideration the appropriateness of employing mobile device management (MDM) solutions to ensure that corporate data is suitably secure. Data Loss Prevention tools Firms should consider appropriateness of data loss prevention tools that enable it to gain visibility of data loss and ultimately provide better detection and prevention of the unauthorised exfiltration of sensitive or confidential corporate data.
2. People Controls
Users have a critical role to play in their Firm’s security and so it is important that policies and procedure, and the technology provided, enable users to do their job as well as keeping the Firm secure. This can be supported by a systematic delivery of awareness programmes and training, that deliver security expertise, as well helping to establish a security-conscious culture. User/staff training Human error is one of the biggest threats to the cyber security of a Firm. All new joiners to the organisation should be clear on the cyber security culture and cyber security training should be mandatory for every new employee. Training programs should be formalised and should be updated and repeated regularly, making cyber training a continuous process. Best practice for a security awareness training program should include, without limitation:
 Email Scams, Phishing and Social Engineering;  Passwords;  Clear Desk Policy;  Bring-Your-Own-Device (“BYOD”) Policy (if the Firm has a BYOD policy);  Data Management;  Removable Media;  Safe Internet Habits;  Physical Security and Environmental Controls;  Social Networking Dangers;  Malware;  Hoaxes. Phishing Testing Formalised and structured phishing testing should be carried out on a regular basis. Simulating phishing attacks enables a Firm to assess its cyber maturity and security awareness, as well as that of its staff, and aids the development of effective phishing awareness training initiatives.

3. Administrative Policy and Governance Controls
   It is important for every Firm to have documented security policies to help protect the Firm’s data and other assets. Documented security policies that clearly define a Firm’s position on security can be of critical importance in the event of a security incident or data breach. Creation and maintenance of policies and procedures The three core objectives for information security policies should be:
    Confidentiality – the protection of IT assets and data from unauthorised users;  Integrity – ensuring that IT assets and data are correct, accurate, able to be relied upon and have not been changed or modified in an unauthorised manner;  Availability – ensuring IT assets, data and networks are available to authorised users. Firms should, at a minimum, consider the following areas when compiling policies and procedures:
    Acceptable Use Policy;
    Confidential Data Policy;
    Email Policy;
    Mobile Device Policy;
    Network Security Policy;
    Password Policy;
    Physical Security Policy;
    Home Working Policy;
    Wireless Network and Guest Access Policy.
   These policies could exist as separate documents or in one single document. Review of existing tools, products and services A Firm should conduct regular reviews of the security tools, products and services that it has in place to ensure that they are:
    fit for purpose;
    being utilised to the fullest extent possible/applicable;  configured to the bespoke needs of the Firm and not left on default ‘out of the box’ configuration settings;  meeting existing and near future needs;  providing appropriate protections for the risks the Firm faces. Management Information Firms should ensure that reporting to the Board, or the relevant board committee, on cyber matters is fit for purpose and contains adequate information to inform the Board and allow it to make decisions and direct attention where it is needed. Where appropriate Firms should have the capability to monitor their networks and detect security related events. Meaningful data should be supplied to the Board. Management Information

(“MI”) should go beyond what is happening at the perimeter of the network and should include what is going on inside the network and what the Firm is doing to defend itself. Relevant MI will differ for each Firm based on its size, nature and complexity. The Commission does not require a Firm to provide a mandated list of MI to its Board but expects a Firm to consider the MI that is relevant to its unique position. A Firm may wish to consider, but is not mandated to, provide the following MI. Current Cyber Security Risks:
 Patching/vulnerability status – details of vulnerabilities not patched across the estate, aged by criticality, i.e. criticals/highs/mediums/lows unpatched over 30, 60, 90, 180, 365 days, etc., with reasons why patches have not been applied or detail of mitigating controls that exist;  List any unsupported operating systems/software, roadmaps to migrate to supported versions or timeline to decommission;  Staff education and awareness updates - how many staff are still to complete mandatory annual security training;  Phishing simulation click rates;  Findings of the most recent penetration test and when findings will be mitigated;  Third Party Management. Emerging Risks, Threats and Vulnerabilities:
 What is happening in terms of emerging risks, threat and vulnerabilities, top stories from open source or other threat intelligence feeds/etc. Incidents:
 Numbers of actual events (with analysis on why, did tools work/not work, whether this is a wider risk, what actions are required, lessons learned, etc.);  Significant near miss events;  Actual breaches;  Data loss events;  Phishing attacks blocked. Compliance Status:
 How compliant is the Firm with any regulatory requirements, standards and any models or accreditations with which it is aligned, either locally or as part of a group entity. Materiality When a Firm reviews or implements cyber controls, policies and procedures it should consider whether these are appropriate for its business and whether they are already covered by existing control frameworks.

Respond and Recover
In the event of a cyber security event occurring Firms are expected to have processes, procedures and controls in place that allow them to assess the damage of the event and to respond and recover as described in the Respond and Recover sections of the Rules. The sophistication of these processes, procedures and controls should be appropriate for the size, nature and complexity of its business. Firms should consider the following controls. Technical Controls Backups A Firm should ensure it has adequate backups both online and offline. Online backups should be connected to systems, and be backed up in real time, and offline backups should not be connected to a machine or to the network so that they cannot be themselves corrupted in the event of ransomware.
5.1 Responding to cyber security events
(1) The licensee must be able to demonstrate that it has a plan in place which aims to mitigate any disruption caused by a cyber security event. (2) Where the licensee is part of a group and the maintenance and recovery of IT systems is controlled at group level; the licensee must be able to demonstrate that it is aware of any group plan specific to the systems it uses and that the plan is appropriate to the licensee. (3) Where the maintenance and recovery of the licensee’s IT systems are outsourced to a third party provider it must ensure that it is aware of any plan which has been put in place, by that provider, and that the plan is appropriate to the licensee.
PART 5 – RESPOND
5.2 Responding to cyber security events
(4) The licensee must be able to demonstrate that it has a plan in place which aims to mitigate any disruption caused by a cyber security event. (5) Where the licensee is part of a group, and the maintenance and recovery of IT systems is controlled at group level, the licensee must be able to demonstrate that it is aware of any group plan specific to the systems it uses, and that the plan is appropriate to the licensee. (6) Where the maintenance and recovery of the licensee’s IT systems are outsourced to a third party provider it must ensure that it is aware of any plan which has been put in place by that provider, and that the plan is appropriate to the licensee.
PART 5 – RESPOND
5.3 Responding to cyber security events
(7) The licensee must be able to demonstrate that it has a plan in place which aims to mitigate any disruption caused by a cyber security event. (8) Where the licensee is part of a group, and the maintenance and recovery of IT systems is controlled at group level, the licensee must be able to demonstrate that it is aware of any group plan specific to the systems it uses, and that the plan is appropriate to the licensee. (9) Where the maintenance and recovery of the licensee’s IT systems are outsourced to
6.1 Recovery from a cyber security event
(1) The licensee must be able to demonstrate that it is aware of the appropriate steps that need to be taken in order to restore business capabilities, following a cyber security event, and ensure essential activities are capable of being undertaken in the interim period.
PART 6 – RECOVER
6.2 Recovery from a cyber security event
(2) The licensee must be able to demonstrate that it is aware of the appropriate steps that need to be taken in order to restore business capabilities following a cyber security event and ensure essential activities are capable of being undertaken in the interim period.
PART 6 – RECOVER
6.3 Recovery from a cyber security event
(3) The licensee must be able to demonstrate that it is aware of the appropriate steps that need to be taken in order to restore business capabilities following a cyber security event and ensure essential activities are capable of being undertaken in the interim period.

A Firm should ensure it tests restoring from backups and that the backups provide the expected restored data. Policy and Governance Controls Incident Response Planning and Exercising around a Cyber Security Event Firms should have a documented incident response plan in place, outlining the actions that should be undertaken in the event of a cyber security event. This plan should be well known to key stakeholders and should be rehearsed on a periodic basis. Recovery Planning following a Cyber Security Event Firms should have a recovery plan in place. Effective planning is a critical component of a Firm’s preparedness for cyber security event recovery. Recovery planning enables Firms to understand system dependencies; critical personnel identities such as crisis management and incident management roles; arrangements for alternate communication channels, services, and facilities; and many other elements of business continuity. Planning also enables Firms to explore “what if” scenarios, which might be largely based on recent cyber security events that have negatively impacted other organisations, in order to develop customised playbooks. Thinking about scenarios helps the Firm to evaluate the potential impact, planned response activities, and resulting recovery processes long before an actual cyber security event takes place. These exercises help identify gaps that can be addressed before a crisis situation, reducing their business impact. Such scenarios also help to exercise both technical and non-technical aspects of recovery such as personnel considerations, legal concerns, and facility issues. Both incident response and recovery plans could be considered as standalone documents or could be included as part of a Firm’s business continuity and disaster recovery plans.

Notification
Notification Requirements
The notification requirements under the Rules are not intended to replace any separate notification requirements a Firm may have. 7.1.Notification to the Commission (1) A licensee must notify the Commission upon becoming aware of a cyber security event which has resulted in – (a) any loss of significant user data; (b) significant loss of availability to IT systems; (c) significant cost to the business; (d) significant loss of business capability; (e) significant loss of service to users. (2) The notification must include the following details pertaining to the cyber security event – (a) date on which it was discovered; (b) date on which it occurred; (c) its nature; (d) current resulting consequences; (e) any possible future consequences; (f) actions taken to mitigate the consequences; (g) any further steps to be taken.

General Provision
8.1.Interpretation
(1)In these Rules terms have their ordinary meaning unless specifically defined. (2)In these Rules the following definitions should be followed - “cyber security event” means any occurrence which threatens, or has the potential to threaten, the confidentiality, integrity or availability of any IT Assets or services utilised by the licensee in the course of its business; “critical infrastructure” means any system or service, utilised by the licensee in the course of its business, the loss of confidentiality, integrity or availability of which would lead to the failure of the operations of the licensee; “trigger event” means any significant occurrence which would indicate that the licensee may be susceptible to a cyber security event. Such occurrences, dependent on severity, may include, but are not limited to – (a) a threat warning generated by internal systems; (b) a vulnerability announcement issued by a software or hardware provider; (c) international warnings of cyber security threats, vulnerabilities or incidents; (d) a system failure where the reason for the failure cannot be traced or may have been the result of a cyber security event. (3)The Interpretation and Standard Provisions (Bailiwick of Guernsey) Law, 2016 applies to the interpretation of these Rules. (4)A reference in these Rules to an enactment should be taken to include any amendments, re-enactments (with or without modification), extensions and applications.

Materiality
The Commission recognises the requirement for the use of judgement when considering various matters within the Rules and this guidance, specifically when considering the terms “trigger event” and “cyber security event”. For example, the Commission would expect that a Firm operating an advanced network monitoring tool would be likely to generate a significant number of threat warnings. However, it would not be expected to treat all those threat warnings as trigger events. Likewise, an internal report of a Firewall or Antimalware system blocking a virus should not automatically be considered a cyber security event. 8.2.Citation and commencement (1) These rules may be cited as the Guernsey Financial Services Commission Cyber Security Rules, 2020. (2) These rules come into force on .

SELF-ASSURANCE. HOME WORKING - INFORMATION SECURITY RISKS Home routers Most employees working from home will make use of a home router in order to access data and if the home router becomes compromised, the home network may be compromised. Employees’ routers may have inadequate Wi-Fi security making it possible for neighbours or other nearby individuals to connect and extract information without trace.

• Have employees using home routers reviewed their router’s security features and enabled
  the highest level of encryption?
• Have employees disabled remote access management from the internet, thereby
  potentially increasing the security of their router and their home working environment?
• Have employees configured and adequately secured their home router? (This might
  include for example the use of complex passwords, ensuring that the default password is modified and checking that any software patches are deployed). Hardware, software and the use of personal devices Some employers will issue staff with hardware supplied by the firm, whilst in other cases staff may use their own devices. If staff use their own devices, then there may be additional security risks. Corporate hardware is likely to be configured to a higher security standard than personal devices. Despite many firms using their own, or a provider’s secure Virtual Private Network (“VPN”), if a personal device has been compromised with a virus or malware, a malicious actor could still access important and confidential data via the recording of keystrokes, or the viewing of an employee’s computer screen.
• Are staff aware, or have they been made aware through training or discussions, of the
  additional risks of using personal devices?
• Do all devices used by employees have adequate anti malware and antivirus protection
  and use the appropriate security settings?

  RELEVANT CONSIDERATIONS

  RELEVANT CONSIDERATIONS

Home equipment may have unpatched vulnerabilities or lack crucial security updates or antivirus protections, which could represent increased risks if these devices are connected to the corporate network.

• Have home working devices been patched and checked regularly to ensure that any
  software updates have been deployed?

• Do devices that employees use to access business systems or applications contain all
  updates installed to the latest versions of operating systems and software? With large volumes of internet users, connection speeds may deteriorate, which could result in users becoming frustrated and choosing to store business data locally on the hard drive of their device, which might mean that there would not be a backup. Additionally, such information may not follow a corporate data classification system and so may be at greater risk of theft, ransom or disruption.

• Is downloading data to devices that are not under the firm’s control discouraged, or even
  prohibited?

• Has web filtering been enabled, so that websites that are known to be compromised or
  linked to malware are not easily accessible to employees?
  The use of shadow IT (i.e. the use of systems, software or applications without explicit IT department approval - for example the ad hoc purchase of video conferencing facilities), may present a risk. When firms moved into lockdown there was an initial rush to ensure that employees were able to work from home. Some employees may have used or downloaded unauthorised software and systems to make their jobs easier. POTENTIAL RISK POTENTIAL RISK POTENTIAL RISK RELEVANT CONSIDERATIONS RELEVANT CONSIDERATIONS

• Has the firm considered whether enterprise licences (which could provide more control
  and allow for the control of configurations), rather than personal licences or free licences, are most appropriate?

• Do employees use only authorised applications, software and services?

• Can employees install software on corporate device devices if such software is not
  approved?

• Have appropriate security provisions been enabled on any cloud service?
  Staffing
  When employees are working outside of the office environment non-employees may also be in the vicinity of the work environment, for example employees may share a house with other occupants, and those occupants may also have visitors. Leaving papers on a desk at home, or leaving a computer unlocked may present additional security risks.

• Are employees able to conduct telephone and video calls discreetly, and in a separate
  room, especially where confidential or sensitive data is being discussed?

• Have your employees been reminded about the importance of information data security?
  Whilst staff are working at home, employers may find it more difficult to identify employees that become disillusioned and this might heighten the risk of unauthorised transfer of key documents or data from the firm’s systems. Staff may move to a different department, or may leave employment, but retain system access.

• Has the firm considered using e-mail scanning which identifies if an employee attempted
  to e-mail key documents outside of the firm?

• Are staff able to download information to personal devices from a remote desktop
  system?

• Are processes in place to track employee changes and is access to systems and data
  (including third party platforms) adequately controlled?

Staff may be less security conscious whilst working from home, meaning that there is an increased risk that employees may be less vigilant with regard to suspicious emails and other security threats.

• Are employees encouraged to keep their work environment separate from their personal
  social media accounts?
• Has additional phishing testing or training been considered?
  Devices (Printers, scanners and USBs)
  Using scanners and printers in the home environment may also create additional risks. Allowing the use of USB sticks and other devices may result in the transfer of viruses and malware
• Are security patches for printer and scanner software up to date?
• Can hard copy confidential information be disposed of securely?
• If use of USB sticks is permitted, are there controls in place?
  Returning to work
  The return of hardware and materials at the point when employees return to the office, may also represent certain risks.
• Has consideration been given to ensuring that returned hardware is appropriately
  inspected and patched?
• Has confidential information, whether it be notes or printed material, been disposed of
  securely?
