Skill Guide
Threat Intelligence & Attack Frameworks (MITRE ATT&CK, TTPs) is the systematic practice of analyzing adversary behavior, mapping it to known frameworks like MITRE ATT&CK, and using this knowledge to improve organizational detection, response, and defensive postures.
Scenario
You are a junior CTI analyst tasked with creating a one-page profile of a notorious APT group (e.g., APT29) for your security operations center (SOC).
Scenario
Your SOC suspects a competitor in your sector is being targeted by a specific threat actor known for credential dumping. You need to test your detections.
Scenario
As a security architect, you are tasked with redesigning the security control budget for the next fiscal year based on a threat-centric approach.
ATT&CK is the primary behavioral model; Navigator visualizes coverage. D3FEND links techniques to defenses. STIX/TAXII standardize intel sharing. The Kill Chain provides a high-phase adversary lifecycle view for strategic planning.
TIPs (OpenCTI, MISP) aggregate and correlate intel. Adversary emulation tools (Caldera) safely simulate TTPs to test detections. SIEM query skills are essential for turning TTPs into actionable hunts. Commercial feeds provide structured, real-time data.
Answer Strategy
Use the Diamond Model or ATT&CK chain to structure the response. Prioritize: 1) Map specific tools/procedures to Techniques (e.g., PsExec -> T1021.002 Remote Services: SMB/Windows Admin Shares). 2) Query SIEM for all historical activity matching those techniques. 3) Issue immediate tactical mitigations (e.g., block C2 IPs, disable PsExec via GPO).
Answer Strategy
Testing for impact and influence. Use the STAR (Situation, Task, Action, Result) method. Emphasize the analytical link: 'We saw Group X using MFA fatigue attacks (T1621) against our sector. I mapped this to our identity provider logs, found we had no alerting. I worked with IAM to implement suspicious MFA volume alerting, which later detected a real attempt.'
