Description

This curriculum spans the design and operational integration of threat intelligence across an ISO 27001-aligned ISMS, comparable in scope to a multi-phase advisory engagement that embeds intelligence practices into risk assessment, control management, third-party oversight, incident response, and audit readiness.

Module 1: Integrating Threat Intelligence into ISMS Scope and Context

Determine which business units and assets require threat intelligence coverage based on criticality and exposure to external attack surfaces.
Define the boundaries of threat intelligence applicability within the ISMS, including cloud environments, third-party ecosystems, and OT systems.
Map threat intelligence inputs to organizational context (e.g., regulatory obligations, supply chain dependencies, geographical operations).
Establish criteria for including or excluding threat data sources based on relevance to the organization’s threat landscape.
Align threat intelligence scope with risk assessment methodologies already in use under ISO 27001:2022 Clause 6.1.2.
Document external and internal stakeholders who influence or are impacted by threat intelligence decisions.
Decide whether threat intelligence will inform only security controls or also business continuity and incident response planning.
Assess the maturity of existing security monitoring capabilities to determine feasibility of integrating proactive threat intelligence.

Module 2: Sourcing and Evaluating Threat Intelligence Feeds

Select commercial, open-source, and ISAC-provided feeds based on format compatibility (STIX/TAXII), update frequency, and specificity to industry sector.
Conduct cost-benefit analysis of paid vs. community-driven intelligence sources, including hidden operational overhead.
Validate the timeliness and accuracy of indicators (IOCs) by correlating with internal detection logs over a trial period.
Implement a scoring system for feed reliability based on false positive rates and historical detection success.
Negotiate data-sharing agreements with peer organizations while ensuring compliance with data protection laws.
Filter out irrelevant threat data (e.g., geographically distant campaigns, non-applicable malware families) to reduce analyst fatigue.
Assess vendor claims of "actionable intelligence" against measurable outcomes such as detection rate improvements.
Establish procedures for rotating or decommissioning underperforming feeds without disrupting monitoring workflows.

Module 3: Aligning Threat Intelligence with Risk Assessment Processes

Modify risk assessment templates to include threat actor capability, intent, and prevalence derived from intelligence sources.
Adjust likelihood ratings in risk registers based on observed targeting patterns affecting peer organizations.
Integrate threat intelligence into scenario development for high-impact risks, such as ransomware or supply chain compromises.
Document how threat data influenced risk treatment decisions, ensuring auditability under ISO 27001 Clause 8.2.
Define thresholds for updating risk assessments when new threat intelligence indicates significant shifts in the landscape.
Coordinate with business risk owners to interpret threat data in the context of operational impact.
Ensure threat-informed risks are traceable to specific controls in the Statement of Applicability (SoA).
Balance intelligence-driven risk adjustments against resource constraints and control feasibility.

Module 4: Operationalizing Threat Intelligence in Security Controls

Configure SIEM correlation rules to ingest and act on IOCs from trusted threat feeds in near real time.
Update firewall and EDR blocklists automatically while maintaining manual override for false positives.
Map MITRE ATT&CK techniques from threat reports to existing defensive controls and identify coverage gaps.
Adjust email gateway filtering rules based on intelligence about active phishing campaigns using organizational branding.
Modify web proxy policies to block domains associated with C2 infrastructure identified in recent reports.
Integrate threat intelligence into vulnerability management by prioritizing patching for systems exposed to active exploitation.
Develop playbooks that trigger specific response actions when threat indicators are detected in network traffic.
Ensure control modifications are logged and reviewed during internal audits for compliance consistency.

Module 5: Threat Intelligence in Third-Party Risk Management

Require vendors to disclose participation in threat information sharing groups as part of due diligence.
Incorporate threat intelligence findings into third-party risk scoring, particularly for providers with access to critical systems.
Monitor for threat reports indicating compromise of supply chain partners and initiate reassessment procedures.
Use breach disclosure data and dark web monitoring to validate vendor security claims.
Define contractual obligations for timely notification of incidents involving shared threat indicators.
Assess the security posture of cloud service providers using threat intelligence on attacks targeting their platforms.
Share anonymized threat data with key partners under legally binding information sharing agreements.
Conduct targeted audits of high-risk vendors when intelligence suggests increased targeting of their sector.

Module 6: Incident Response and Threat Intelligence Integration

Pre-load incident response toolkits with threat profiles relevant to the organization’s industry and technology stack.
Use threat actor TTPs to guide forensic investigation scope during active incidents.
Compare observed attack patterns against known adversary campaigns to support attribution and response strategy.
Update IR playbooks to include intelligence-driven containment and eradication steps.
Establish a process for feeding internal incident findings back into threat intelligence repositories.
Coordinate with external CSIRTs when threat data indicates coordinated attacks across multiple organizations.
Preserve threat intelligence context in incident reports for regulatory reporting and executive briefings.
Conduct post-incident reviews to evaluate whether available intelligence could have accelerated detection or response.

Module 7: Governance and Oversight of Threat Intelligence Programs

Define roles and responsibilities for threat intelligence management within the information security team and SOC.
Establish KPIs such as time-to-integrate intelligence, detection rate improvements, and false positive ratios.
Report threat intelligence effectiveness to the information security steering committee on a quarterly basis.
Conduct periodic reviews of intelligence program alignment with ISO 27001 control objectives.
Ensure threat intelligence activities comply with privacy regulations when handling personal or third-party data.
Maintain documentation of intelligence sources, usage, and decisions for internal and external audits.
Review access controls to threat intelligence platforms to prevent unauthorized dissemination of sensitive data.
Assess the impact of intelligence program changes on other ISMS processes during management review meetings.

Module 8: Threat Intelligence in Internal and External Audits

Prepare evidence that threat intelligence inputs are considered during risk assessments and control selection.
Demonstrate traceability from threat data to specific control enhancements or policy updates.
Provide logs showing regular ingestion and evaluation of threat intelligence feeds during audit walkthroughs.
Justify exclusion of certain threat sources by documenting relevance assessments and risk-based rationale.
Respond to auditor findings on intelligence gaps by initiating targeted capability improvements.
Use threat intelligence summaries to support audit sampling decisions for high-risk areas.
Ensure audit checklists include verification of threat-informed control testing procedures.
Coordinate with external auditors on the scope of threat intelligence review to avoid disclosure of sensitive sources.

Module 9: Sustaining and Evolving the Threat Intelligence Capability

Conduct annual maturity assessments of the threat intelligence function using frameworks such as VERIS or NIST CSF.
Adjust intelligence collection priorities based on changes in business strategy, such as market expansion or M&A activity.
Invest in staff training to maintain proficiency in analyzing advanced threat reports and adversary behaviors.
Upgrade tooling to support automation, such as SOAR integration for IOC ingestion and response triggering.
