Implementing Threat Intelligence Lifecycle Management
Overview
The threat intelligence lifecycle is a structured, iterative process for transforming raw data into actionable intelligence. Based on the intelligence cycle used by military and government agencies, it comprises six phases: Direction (requirements gathering), Collection (data acquisition), Processing (normalization and deduplication), Analysis (contextualization and assessment), Dissemination (distribution to stakeholders), and Feedback (evaluation and refinement). This skill covers building each phase with tooling, metrics, and integration points for a mature CTI program.
When to Use
Trigger phrases:
"implementing threat intelligence lifecycle management"
"Implement a structured threat intelligence lifecycle encompassing planning, coll"
When deploying or configuring implementing threat intelligence lifecycle management capabilities in your environment

Key Concepts
This section covers key concepts for implementing threat intelligence lifecycle management.
Ensure all prerequisites are met before proceeding
Follow the documented workflow steps in sequence
Record results and any anomalies encountered during this phase
Intelligence Requirements (IR)
Priority Intelligence Requirements (PIRs) define what the organization needs to know. Examples: Which threat actors target our sector? What vulnerabilities are being actively exploited? Are our brand or credentials being traded on dark web? PIRs drive collection planning and ensure intelligence production is relevant.
Collection Management Framework
A collection management framework maps intelligence requirements to collection sources, tracks collection gaps, and ensures coverage across the threat landscape. Sources include OSINT, commercial feeds, ISAC sharing, internal telemetry, and human intelligence from industry contacts.
Intelligence Levels Strategic intelligence informs executive decision-making (threat landscape, risk trends, geopolitical context). Operational intelligence supports security operations (campaign tracking, actor TTPs, attack timing). Tactical intelligence enables immediate defense (IOCs, detection rules, blocklists).
Workflow
Scope the task — define objectives, boundaries, and success criteriaGather information — collect all necessary data and context before proceedingExecute the core workflow — follow the domain-specific steps methodicallyValidate results — verify outputs against expected outcomes or baselinesDocument findings — record results, anomalies, and recommendations

Validation Criteria
Intelligence requirements defined with priorities and stakeholders
Collection pipeline gathering from multiple sources
Processing deduplicates and normalizes data correctly
Analysis produces intelligence answering specific requirements
Dissemination reaches appropriate stakeholders through right channels
Feedback mechanism captures and incorporates stakeholder input
When NOT to Use
You need to test the implementation (use performing-* skills)
Task is about configuring existing tools (use configuring-* skills)
You need to analyze security events (use analyzing-* skills)
Task is about building detection rules (use building-* skills)
You don't have access to the target environment
Task requires vendor-specific expertise (consult vendor docs)
Red Flags
Performing actions without explicit written authorization from the asset owner
Testing against production systems without a defined scope and rules of engagement
Acting on threat intelligence without validating source reliability
Sharing classified or sensitive indicators without proper handling procedures
Alerting threat actors to detection capabilities through visible response actions
Verification
All steps executed successfully against a test environment before production use
Output documented with screenshots or logs demonstrating expected behavior
Results validated against known-good baselines or reference implementations
Documentation complete enough for another analyst to reproduce findings
References
Process
Analyze the task requirements
Apply domain expertise
Verify output quality
Anti-Rationalization Table Rationalization Reality "We are too small to be targeted" Automated attacks target everyone. Size does not matter. "Security slows us down" A breach slows you down 100x more. Build security in from the start. "We will fix it after launch" Vulnerabilities in production are exploited within hours. Fix before deploy.
