ISO 27001 Annex A: A.16

This security incident response policy is intended to establish controls to ensure detection of security vulnerabilities and incidents, as well as quick reaction and response to security breaches.
This document also provides implementing instructions for security incident response, to include definitions, procedures, responsibilities, and performance measures (metrics and reporting mechanisms).
This policy applies to all users of information systems within Affiliatly. This typically includes employees and contractors, as well as any external parties that come into contact with systems and information controlled by Affiliatly (hereinafter referred to as “users”). This policy must be made readily available to all users.
A key objective of Affiliatly’s Information Security Program is to focus on detecting information security weaknesses and vulnerabilities so that incidents and breaches can be prevented wherever possible. Affiliatly is committed to protecting its employees, customers, and partners from illegal or damaging actions taken by others, either knowingly or unknowingly. Despite this, incidents and data breaches are likely to happen; when they do, Affiliatly is committed to rapidly responding to them, which may include identifying, containing, investigating, resolving , and communicating information related to the breach.
This policy requires that all users report any perceived or actual information security vulnerability or incident as soon as possible using the contact mechanisms prescribed in this document. In addition, Affiliatly must employ automated scanning and reporting mechanisms that can be used to identify possible information security vulnerabilities and incidents. If a vulnerability is identified, it must be resolved within a set period of time based on its severity. If an incident is identified, it must be investigated within a set period of time based on its severity. If an incident is confirmed as a breach, a set procedure must be followed to contain, investigate, resolve, and communicate information to employees, customers, partners and other stakeholders.
Within this document, the following definitions apply:
- Information Security Vulnerability:
A vulnerability in an information system, information system security procedures, or administrative controls that could be exploited to gain unauthorized access to information or to disrupt critical processing.
- Information Security Incident:
A suspected, attempted, successful, or imminent threat of unauthorized access, use, disclosure, breach, modification, or destruction of information; interference with information technology operations; or significant violation of information security policy.
4. Roles and Responsibilities
The acting Information Security Manager (ISM) and team will facilitate and maintain this policy and ensure all employees have reviewed and read the policy.
- All users must report any system vulnerability, incident, or event pointing to a possible Incident to the Information Security Manager (ISM) as quickly as possible but no later than 24 hours.
- Incidents must be reported by sending an email message to firstname.lastname@example.org or to the acting information security officer with details of the incident.
- Users must be trained on the procedures for reporting information security incidents or discovered vulnerabilities, and their responsibilities to report such incidents. Failure to report information security incidents shall be considered to be a security violation and will be reported to the Operations Manager for disciplinary action.
- Information and artifacts associated with security incidents (including but not limited to files, logs, and screen captures) must be preserved in the event that they need to be used as evidence of a crime.
- All information security incidents must be responded to through the incident management procedures defined below.
It is important to note that the processes surrounding security incident response should be periodically reviewed and evaluated for effectiveness. This also involves appropriate training of resources expected to respond to security incidents, as well as the training of the general population regarding Affiliatly’s expectation for them, relative to security responsibilities. The incident response plan is tested annually.
Procedure For Establishing Incident Response System:
- Define on-call schedule and assign the Information Security Manager (ISM) as responsible for managing incident response procedure during each availability window.
- Define notification channel to alert the on-call ISM of a potential security incident. Establish a company resource that includes up to date contact information for on-call ISM.
- Assign the Operations Manager as default collaborator for management collaboration during the execution of the plan.
- Distribute Procedure For Executing Incident Response to all staff and ensure up-to-date versions are accessible in a dedicated company resource.
- Require all staff to complete training for Procedure For Executing Incident Response at least once per year.
The following situations are to be considered for information security event reporting:
- Ineffective security control;
- Breach of information integrity, confidentiality or availability expectations;
- Human errors;
- Non-compliances with policies or guidelines;
- Breaches of physical security arrangements;
- Uncontrolled system changes;
- Malfunctions of software or hardware;
- Access violations; and,
- Malfunctions or other anomalous system behavior indicative of a security attack or actual security breach.
Procedure For Executing Incident Response:
- When an information security incident is identified or detected, users must notify their immediate manager within 24 hours. The manager must immediately notify the ISM on call for proper response. The following information must be included as part of the notification:
- Description of the incident
- Date, time, and location of the incident
- Person who discovered the incident
- How the incident was discovered
- Known evidence of the incident
- Affected system(s)
- Within 48 hours of the incident being reported, the ISM shall conduct a preliminary investigation and risk assessment to review and confirm the details of the incident. If the incident is confirmed, the ISM must assess the impact to Affiliatly and assign a severity level, which will determine the level of remediation effort required:
- High: the incident is potentially catastrophic to Affiliatly and/or disrupts Affiliatly’s day-to-day operations; a violation of legal, regulatory or contractual requirements is likely.
- Medium: the incident will cause harm to one or more merchant users within Affiliatly and/or will cause delays to a merchant user’s activities.
- Low: the incident is a clear violation of organizational security policy, but will not substantively impact the business.
- The ISM, in consultation with the Operations Manager, shall determine appropriate incident response activities in order to contain and resolve incidents.
- The ISM must take all necessary steps to preserve forensic evidence (e.g. log information, files, images) for further investigation to determine if any malicious activity has taken place. All such information must be preserved and provided to law enforcement if the incident is determined to be malicious.
- If the incident is deemed as High or Medium, the ISM must work with the Operations Manager to create and execute a communications plan that communicates the incident to users, the public, and others affected.
- The ISM must take all necessary steps to resolve the incident and recover information systems, data, and connectivity. All technical steps taken during an incident must be documented in Affiliatly’s incident log, and must contain the following:
- Description of the incident
- Incident severity level
- Root cause (e.g. source address, website malware, vulnerability)
- Mitigations applied (e.g. patch, re-image)
- Status (open, closed, archived)
- Disclosures (parties to which the details of this incident were disclosed to, such as customers, vendors, law enforcement, etc.)
- After an incident has been resolved, the ISM must conduct a post-mortem that includes root cause analysis and documentation of any lessons learned.
- Depending on the severity of the incident, the Owner (CEO) may elect to contact external authorities, including but not limited to law enforcement, private investigation firms, and government organizations as part of the response to the incident.
- The ISM must notify all users of the incident, conduct additional training if necessary, and present any lessons learned to prevent future occurrences. Where necessary, the Operations Manager must take disciplinary action if a user’s activity is deemed as malicious.
