Vulnerability Assessment

The process of identifying, quantifying, and prioritising security vulnerabilities in systems and applications.

Penetration Testing

A simulated cyberattack against a system to evaluate the security of its defences and identify exploitable vulnerabilities.

Red Team

A group of security professionals who simulate real-world attacks to test an organisation's defensive capabilities.

Blue Team

A group of security professionals who defend against both real attackers and simulated attacks from red teams.

Purple Team

A collaborative security approach combining red team attack knowledge with blue team defensive capabilities.

Intrusion Prevention System
