In a nutshell: TTP-Chaining validates the exploitability of security vulnerabilities by checking the underlying attack techniques without executing exploits themselves.
Many critical security vulnerabilities cannot be safely validated with real exploits – either because no exploit is available or the system is too critical for testing. TTP-Chaining makes it possible to assess exploitability by validating the underlying attack techniques without running the exploit itself.
Classical vulnerability assessments face a fundamental dilemma in practice: many identified security vulnerabilities cannot be validated through real exploits without endangering the system or disrupting production operations. This is particularly true for critical infrastructure, financial or healthcare systems.
TTP-Chaining (Tactic, Technique, Procedure Chaining) offers an alternative validation approach. Instead of actually executing an exploit, the individual attack techniques and procedures that the exploit relies on are systematically checked. This makes it possible to determine whether a security vulnerability is actually exploitable – without risking actual damage or disrupting operations.
For CISOs, this means pragmatic risk quantification: they can distinguish exploitable from non-exploitable security vulnerabilities, set remediation priorities realistically, and fulfil compliance requirements without exposing critical systems to an exploitation attempt. The procedure thus closes the gap between complete security and practical feasibility.
