NIST SP 800-53 is a security and privacy control standard for information systems and organizations. Threat hunters use it as a reference when formalizing a threat-hunting practice, especially in organizations structured around NIST controls. section 2.7.2 section 2.0
Key features relevant to threat hunting include:
- Rev. 5 organizes controls into three impact classes: low, moderate, and high, and 18 control families. section 2.7.2
- Risk Assessment control RA-10 establishes and maintains a cyber threat-hunting capability. section 2.7.2
- RA-10 directs hunters to search for indicators of compromise and detect, track, and disrupt threats that evade existing controls. section 2.7.2
- Threat hunting is framed as active defense through proactive searches across organizational systems, networks, and infrastructure. section 2.7.2
Applying RA-10
A security team can use RA-10 to justify and structure hunts for advanced threats that bypass firewalls, intrusion prevention, sandboxing, or security information and event management technologies. section 2.7.2
