Implementing ISO 27001 Annex A 5.7 is the strategic process of gathering, analysing, and distributing Threat Intelligence to inform risk-based decision-making. It requires organizations to filter global security feeds against their specific asset inventory to identify relevant vulnerabilities, document the business impact, and execute targeted remediation actions to preemptively secure critical systems against evolving attack vectors.
ISO 27001 Threat Intelligence Implementation Checklist
Use this implementation checklist to achieve compliance with ISO 27001 Annex A 5.7. Compliance with this control requires a manual, analytical process to identify, filter, and act upon security threats relevant to your specific technology stack, not just a passive subscription to a news feed.
1. Audit and Define Critical Assets
Control Requirement: The organization must determine which information relating to information security threats is relevant to its specific environment.
Required Implementation Step: Open your Asset Register (Excel or CSV). Filter for ‘Critical’ assets. List the specific hardware (e.g., Dell PowerEdge), operating systems (e.g., Ubuntu 22.04), and software stacks (e.g., Nginx, PostgreSQL) that support these assets. You cannot gather intelligence if you do not know what you are defending.
Minimum Requirement: A list of the top 5 critical technologies used by the business, saved in
/compliance/threat-intel/scope.txt.
2. Configure Vendor-Specific Direct Alerts
Control Requirement: Information regarding threats must be collected from relevant sources.
Required Implementation Step: Log in to the administrative consoles of your critical vendors (e.g., AWS Health Dashboard, Microsoft 365 Admin Center, Adobe Admin Console). Configure email alerts specifically for “Security Advisories” and “Critical Vulnerabilities” to be sent to a dedicated technical distribution list (e.g., sec-ops@company.com), not a generic “info@” address.
Minimum Requirement: Screenshot evidence of notification settings enabled for your primary Cloud Service Provider (CSP).
3. Subscribe to National CERT/CSIRT Feeds
Control Requirement: The organization must monitor specialized interest groups and government advisories.
Required Implementation Step: Manually subscribe to the mailing list of your national Computer Emergency Response Team (e.g., NCSC in the UK, CISA in the US). Select options for “Weekly Threat Reports” and “Critical Alerts” only to avoid alert fatigue. Do not rely on Twitter or RSS feeds that cannot be audited easily.
Minimum Requirement: A confirmation email from the national CERT stored in your evidence folder.
