Information security incidents should be responded to by a designated team with the required competency (see A.5.24). The incident response should: a) outline the systems affected by the incident; b) include evidence (see A.5.28) as soon as possible after the occurrence; c) follow the escalation procedures as outlined in business continuity plans (see A.5.29 and A.5.30); d) ensure that all involved response activities are properly logged for later analysis; e) communicate the existence of the information security incident or any relevant details thereof to all relevant internal and external interested parties following the need-to-know principle; f) coordinate with internal and external parties such as authorities, external interest groups and forums, suppliers and clients to improve response effectiveness and help to minimise consequences for other organisations; g) once the incident has been successfully addressed, follow procedure to formally close and record it; h) conduct information security forensic analysis, as required (see A.5.28); i) include post-incident analysis to identify root cause. Ensure it is documented and communicated according to defined procedures (see A.5.27); j) identify and manage information security vulnerabilities and weaknesses including those related to controls which have caused, contributed to or failed to prevent the incident. - [Getting Started](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#main-content) - [Getting Started](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#getting-started) - [Accounts & Billing](https://knowledge.adoptech.co.uk/getting-started?hsLang=en#accounts-billing) - [FAQ's on Adoptech](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#main-content) - [Frameworks](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#frameworks) - [Policies & Documents](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#policies-documents) - [Risk Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#risk-management) - [Supplier Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#supplier-management) - [Audit Preparation](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#audit-preparation) - [Trust Centre](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#trust-centre) - [User Management](https://knowledge.adoptech.co.uk/faqs-on-adoptech?hsLang=en#user-management) - [Frameworks & Certifications](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#main-content) - [ISO 27001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-27001) - [ISO 42001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-42001) - [Cyber Essentials](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#cyber-essentials) - [CAF](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#caf) - [PCI-DSS](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#pci-dss) - [SOC2](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#soc2) - [Data Privacy (GDPR)](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#data-privacy-gdpr) - [DORA](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#dora) - [ISO 9001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-9001) - [ISO 22301](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-22301) - [ISO 14001](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-14001) - [NIST 800-53](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nist-800-53) - [NIST-CSF](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nist-csf) - [NIS2](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#nis2) - [ISO 20000-1](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#iso-20000-1) - [HIPAA](https://knowledge.adoptech.co.uk/frameworks-certifications?hsLang=en#hipaa) - [Integrations](https://knowledge.adoptech.co.uk/integrations?hsLang=en#main-content) - [Cloud Infrastructure](https://knowledge.adoptech.co.uk/integrations?hsLang=en#cloud-infrastructure) - [Identity & Access](https://knowledge.adoptech.co.uk/integrations?hsLang=en#identity-access) - [DevOps & Code](https://knowledge.adoptech.co.uk/integrations?hsLang=en#devops-code) - [Project Management](https://knowledge.adoptech.co.uk/integrations?hsLang=en#project-management) - [HR & People Systems](https://knowledge.adoptech.co.uk/integrations?hsLang=en#hr-people-systems) - [Security & Devices](https://knowledge.adoptech.co.uk/integrations?hsLang=en#security-devices) - [Communication & Collaboration](https://knowledge.adoptech.co.uk/integrations?hsLang=en#communication-collaboration) - [Legal & Regulations](https://knowledge.adoptech.co.uk/legal-regulations?hsLang=en) - [Security Guidance](https://knowledge.adoptech.co.uk/security-guidance?hsLang=en) - [Troubleshooting](https://knowledge.adoptech.co.uk/troubleshooting?hsLang=en) [![Chill listening crop-3](https://knowledge.adoptech.co.uk/hs-fs/hubfs/adoptech-logo-1.png?width=209&height=54&name=adoptech-logo-1.png "Chill listening crop-3")](https://adoptech.co.uk/) Copyright © 2026, Adoptech Ltd.
