ISO 27001 Threat Intelligence Procedure Template

Introduction

Organizations face continuous threats from cybercriminals seeking to compromise systems, steal information, disrupt operations, or exploit vulnerabilities. To protect the confidentiality, integrity, and availability of information, organizations need a structured process for identifying, assessing, communicating, and responding to current and emerging threats. ISO/IEC 27001 specifies requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). Under ISO/IEC 27001:2022, Annex A control 5.7 specifically addresses threat intelligence and requires information relating to information security threats to be collected and analyzed to produce relevant intelligence. This article explains the essential elements of a Threat Intelligence Procedure and how it supports an organization’s ISMS and overall security posture.

Why Threat Intelligence Is Important for ISO 27001?

Threat intelligence helps an organization move beyond relying only on historical incidents. It provides current, relevant, and actionable information about threat actors, vulnerabilities, attack methods, indicators of compromise, and changes in the external threat environment.

A structured threat intelligence capability supports several areas of ISO/IEC 27001:2022 and its Annex A controls:

• Threat intelligence—Annex A 5.7: Information about existing and emerging threats should be collected, analyzed, and converted into relevant intelligence.
  
  

• Information security risk assessment—Clause 6.1.2: Threat intelligence provides context for identifying threats, evaluating risk, and reviewing changes in the organization’s risk environment.
  
  

• Information security incident management—Annex A 5.24 to 5.27: Intelligence can improve incident preparation, event assessment, response, and learning from incidents.
  
  

• Management of technical vulnerabilities—Annex A 8.8: Threat information helps the organization prioritize vulnerabilities according to exploit activity, exposure, and business impact.
  
  

• Monitoring activities—Annex A 8.16: Indicators of compromise and attacker behavior can strengthen security monitoring and detection rules.
  
  

• Independent review—Annex A 5.35: Threat intelligence processes and outputs can be reviewed to confirm their continued suitability and effectiveness.
  
  

• Continual improvement—Clause 10: Lessons learned from threats, incidents, exercises, and feedback can be used to improve the ISMS.

Threat intelligence should be proportionate to the organization’s size, activities, technology, information assets, risk profile, and operating environment.

What Is a Threat Intelligence Procedure?

A Threat Intelligence Procedure is a formal document that explains how an organization plans, collects, processes, analyzes, disseminates, reviews, and improves information about current and potential threats to its information assets.

The procedure ensures that threat intelligence activities are performed consistently and that raw threat data is converted into useful information for decision-makers, security teams, risk owners, and other relevant stakeholders.

Effective threat intelligence should be:

• Relevant: Connected to the organization’s assets, services, industry, geography, suppliers, and risks.
  
  

• Accurate: Based on reliable sources and appropriately validated.
  
  

• Timely: Delivered early enough to support preventive or corrective action.
  
  

• Actionable: Presented in a form that enables recipients to make decisions or implement controls.
  
  

• Controlled: Collected, handled, shared, retained, and protected according to defined requirements.

ISO 27001 Threat Intelligence Procedure: Seven Key Components

The procedure should cover the complete intelligence lifecycle. The following seven components provide a clear and practical structure.

Purpose, Scope, Roles, and Responsibilities

The procedure should begin by explaining why the threat intelligence process exists, what it covers, and who is responsible for each activity.

• Purpose: Establish a consistent process for collecting, analyzing, communicating, and applying actionable threat intelligence to protect the organization’s information and support its ISMS.
  
  

• Scope: Identify the information assets, systems, networks, cloud services, business processes, locations, suppliers, and organizational units covered by the procedure.
  
  

• CISO or Information Security Manager: Oversee the threat intelligence program, approve priorities, provide resources, and report significant matters to management.
  
  

• Threat Intelligence Analysts: Collect, process, validate, analyze, and document threat information.
  
  

• Security Operations Centre Team: Use intelligence to improve monitoring, detection, investigation, and response activities.
  
  

• Incident Response Team: Apply intelligence when preparing for, investigating, containing, and learning from incidents.
  
  

• Risk Management Team: Use relevant intelligence to update risk assessments, treatment plans, and control priorities.
  
  

• Vulnerability Management Team: Use intelligence to prioritize vulnerabilities and remediation activities.
  
  

• System and Asset Owners: Assess how identified threats may affect their systems and implement required actions.
  
  

• Senior Management: Review significant intelligence reports, accept material risks where authorized, and support strategic decisions.

The procedure should also define segregation of duties, escalation authority, and responsibilities for approving intelligence products and external sharing.

Intelligence Requirements, Planning, and Direction

Planning identifies what the organization needs to know and ensures that intelligence activities focus on business priorities rather than collecting information without a clear purpose.

Priority Intelligence Requirements should be based on critical assets, business objectives, regulatory obligations, threat exposure, recent incidents, and stakeholder needs.

Examples include:

• Industry threats: What are the most significant cybersecurity threats affecting the organization’s industry?
  
  

• Critical systems: Are new threats or vulnerabilities targeting the organization’s critical systems, applications, or technologies?
  
  

• Threat actors: Which threat groups are likely to target the organization, and what are their motives and capabilities?
  
  

• Ransomware activity: Which tactics, techniques, and procedures are being used by ransomware groups targeting similar organizations?
  
  

• Supply-chain threats: Could geopolitical events, supplier compromises, or third-party vulnerabilities affect the organization?
  
  

• Emerging technologies: What risks are associated with newly adopted cloud, AI, operational technology, or remote-working solutions?

Each requirement should identify its owner, intended users, priority, review frequency, information sources, and expected output.

Threat Intelligence Collection

The collection phase identifies approved sources and gathers information relevant to the organization’s intelligence requirements.

• Open-Source Intelligence: Public information from government advisories, security researchers, news outlets, vendor blogs, vulnerability databases, and other reputable sources.
  
  

• Commercial intelligence feeds: Subscription services providing indicators, threat-actor profiles, vulnerability intelligence, or other specialist information.
  
  

• Information-sharing groups: Sector-based Information Sharing and Analysis Centres, Information Sharing and Analysis Organizations, professional groups, and trusted communities.
  
  

• Government and law-enforcement sources: Alerts, advisories, reports, and notifications issued by relevant authorities.
  
  

• Internal sources: Security logs, incident records, vulnerability scans, endpoint tools, firewalls, intrusion-detection systems, email-security tools, and threat intelligence platforms.
  
  

• Supplier and partner sources: Notifications and intelligence received from service providers, customers, vendors, and other trusted parties.
  
  

• Deep-web or dark-web sources: Information collected through lawful, authorized, and appropriately controlled monitoring activities.
  
  

• Human intelligence: Information provided by subject-matter experts, employees, partners, or other authorized contacts where appropriate.

The procedure should define source-approval criteria, reliability ratings, collection frequency, legal restrictions, privacy requirements, access controls, and rules for handling sensitive information.

Processing, Validation, and Analysis

Collected data must be prepared, validated, and analyzed before it can be treated as actionable intelligence.

Processing activities may include:

• Parsing: Extracting relevant fields from reports, alerts, feeds, and logs.
  
  

• Normalization: Converting information into consistent formats.
  
  

• De-duplication: Removing repeated or overlapping records.
  
  

• Enrichment: Adding context such as asset exposure, geography, threat-actor information, vulnerability severity, or observed exploitation.
  
  

• Aggregation: Combining related information from different sources.
  
  

• Validation: Checking the accuracy, reliability, timeliness, and relevance of the information.

Analysis methods may include:

• Contextual analysis: Determining whether a threat is relevant to the organization and its environment.
  
  

• Correlation: Identifying relationships among indicators, incidents, vulnerabilities, actors, and affected assets.
  
  

• Attribution: Assessing the likely origin or responsible threat actor while clearly stating the level of confidence and uncertainty.
  
  

• Impact analysis: Evaluating the potential operational, financial, legal, security, privacy, and reputational effects of a threat.
  
  

• Framework mapping: Organizing attacker behavior using recognized frameworks.
  
  

• Indicator and TTP analysis: Identifying indicators of compromise and attacker tactics, techniques, and procedures.
  
  

• Risk prioritization: Ranking threats according to likelihood, exposure, exploitability, business impact, and control effectiveness.

The analysis should document assumptions, source confidence, analytical confidence, limitations, and recommended actions.

Intelligence Production, Dissemination, and Escalation

Analyzed intelligence should be converted into products suitable for its intended audience and delivered through approved channels.

• Strategic intelligence: High-level information for senior management concerning threat trends, business risks, investment priorities, and long-term security strategy.
  
  

• Operational intelligence: Information supporting incident preparation, threat hunting, investigation, and coordinated security operations.
  
  

• Tactical intelligence: Details of attacker behaviors, campaigns, tactics, techniques, and procedures used to improve controls and detection capabilities.
  
  

• Technical intelligence: Indicators such as malicious addresses, domains, hashes, signatures, or detection rules intended for security tools and technical teams.

The procedure should define:

• Reporting format: Alerts, dashboards, briefings, intelligence reports, tickets, or machine-readable feeds.
  
  

• Recipients: The roles, teams, suppliers, customers, or authorities authorized to receive each type of intelligence.
  
  

• Frequency: Real-time, daily, weekly, monthly, quarterly, or event-driven reporting.
  
  

• Classification and handling: How intelligence products are labelled, protected, retained, and shared.
  
  

• Escalation thresholds: Conditions requiring urgent notification, incident activation, risk reassessment, or management attention.
  
  

• Recommended actions: The changes to controls, monitoring, patching, configurations, communications, or response plans expected from recipients.

Sensitive intelligence should only be shared with authorized recipients and in accordance with legal, contractual, privacy, and information-sharing requirements.

Integration With the ISMS and Security Operations

Threat intelligence creates value when it informs decisions and produces measurable security action. The procedure should explain how intelligence is integrated into the organization’s ISMS and operational processes.

• Risk management: Update threat scenarios, likelihood assessments, risk ratings, treatment plans, and control priorities.
  
  

• Vulnerability management: Prioritize remediation based on active exploitation, threat-actor interest, asset criticality, and exposure.
  
  

• Security monitoring: Create or improve alerts, signatures, detection rules, dashboards, and threat-hunting activities.
  
  

• Incident management: Strengthen preparation, triage, investigation, containment, recovery, and lessons learned.
  
  

• Security architecture: Inform the selection, design, configuration, and improvement of preventive and detective controls.
  
  

• Supplier management: Assess threats involving vendors, cloud providers, managed services, software dependencies, and supply chains.
  
  

• Awareness and training: Update personnel on relevant phishing themes, attacker behavior, scams, vulnerabilities, and emerging risks.
  
  

• Business continuity: Consider threat scenarios that may disrupt critical services, facilities, suppliers, or technology.
  
  

• Management review: Present significant trends, exposures, outcomes, resource needs, and performance results to management.

Actions arising from intelligence should be assigned to owners, given due dates, tracked to completion, and verified for effectiveness.

Feedback, Performance Measurement, Review, and Improvement

The final component ensures that the procedure remains useful, efficient, and responsive to changes in the threat environment.

• User feedback: Obtain feedback from intelligence consumers on relevance, timeliness, accuracy, clarity, and usefulness.
  
  

• Performance measures: Monitor agreed indicators such as reporting timeliness, source reliability, number of actionable findings, detection improvements, remediation outcomes, and stakeholder satisfaction.
  
  

• False-positive and false-negative analysis: Review inaccurate or missed intelligence to improve sources, tools, and analytical methods.
  
  

• Lessons learned: Incorporate findings from incidents, exercises, threat hunts, audits, and completed intelligence activities.
  
  

• Requirement review: Confirm that intelligence requirements continue to reflect the organization’s assets, risks, strategy, and operating environment.
  
  

• Source review: Reassess the quality, legality, cost, relevance, and reliability of intelligence sources.
  
  

• Procedure review: Review the complete procedure at planned intervals and after significant incidents, organizational changes, or major changes in the threat landscape.
  
  

• Approval and version control: Record the procedure owner, approver, version, effective date, changes, and next review date.

Improvement actions should be documented, assigned, monitored, and incorporated into the ISMS.

Benefits of a Threat Intelligence Procedure

An effective Threat Intelligence Procedure can provide the following benefits:

• Earlier threat identification: Detect potential threats and vulnerabilities before they cause significant harm.
  
  

• Risk-based prioritization: Focus resources on threats that are most relevant to critical information and business services.
  
  

• Proactive security: Move from reactive incident handling toward prevention, preparation, and early detection.
  
  

• Faster incident response: Provide incident teams with timely indicators, context, and attacker behavior information.
  
  

• Better security investment decisions: Support informed decisions about tools, staffing, controls, and remediation priorities.
  
  

• Improved security posture: Strengthen monitoring, vulnerability management, security architecture, and user awareness.
  
  

• Business alignment: Connect security activities with organizational objectives, risk appetite, and operational priorities.
  
  

• ISO 27001 support: Provide evidence that threat information is systematically collected, analyzed, communicated, and applied.

Tips for Implementing the Procedure

1. Start small and scale gradually: Begin with a limited number of high-priority intelligence requirements and expand the program as its capability matures.
   
   

2. Define measurable objectives: Establish what the program is expected to achieve and how success will be evaluated.
   
   

3. Use reliable sources: Approve and periodically assess sources for relevance, timeliness, accuracy, and legal acceptability.
   
   

4. Train analysts and consumers: Ensure that analysts can evaluate intelligence and that recipients understand how to apply it.
   
   

5. Gain executive support: Explain how the program reduces risk, supports decisions, and protects critical business objectives.
   
   

6. Integrate existing tools: Use security platforms, logs, vulnerability-management tools, incident systems, and risk registers to avoid isolated intelligence activities.
   
   

7. Protect the intelligence: Apply classification, access, retention, and sharing controls appropriate to its sensitivity.

Conclusion

An ISO 27001-aligned Threat Intelligence Procedure provides a consistent method for turning threat data into actionable security intelligence. By defining requirements, sources, analytical methods, reporting arrangements, ISMS integration, responsibilities, and improvement activities, the organization can strengthen its ability to anticipate and respond to evolving threats. The procedure supports ISO/IEC 27001:2022 Annex A control 5.7 and contributes to risk assessment, vulnerability management, monitoring, incident management, and continual improvement. However, a procedure alone does not establish conformity or guarantee certification. The organization must implement the process, apply relevant intelligence, monitor its effectiveness, and retain appropriate evidence within the ISMS.
