TECHNICAL DEFINITION

In cybersecurity incident response and threat intelligence, a 'skill' refers to a granular, atomic adversary technique or procedure used to accomplish a tactical objective within an attack lifecycle. These skills are often mapped to frameworks like MITRE ATT&CK (as techniques or sub-techniques) and are used in SOAR platforms to trigger automated defensive playbooks.

BACKGROUND

In computer security, Capture the Flag (CTF) is an exercise in which participants attempt to find text strings, called "flags", which are secretly hidden in purposefully vulnerable programs or websites. They can be used for both competitive or educational purposes. In two main variations of CTFs, participants either steal flags from other participants or from organizers. A mixed competition combines these two styles. Competitions can include hiding flags in hardware devices, they can be both online or in-person, and can be advanced or entry-level. The game is inspired by the traditional outdoor sport with the same name. CTFs are used as a tool for developing and refining cybersecurity skills, making them popular in both professional and academic settings.
