Intrusion detection
The process of monitoring the events occurring in a computer system or network to detect signs of
unauthorized access or attack.20
Nation-state attack
A cyber-attack conducted by nation states or state-backed cybercriminals.
Penetration testing
An evaluation methodology whereby assessors search for vulnerabilities and attempt to circumvent the

set of risks24
A rootkit is a clandestine computer program designed to provide continued privileged access to a
computer while actively hiding its presence25
Spear Phishing
Spear phishing is a phishing method that targets specific individuals or groups within an organization. It is
