Penetration testing simulates attacks to expose exploitable weaknesses and likely business impact, supporting risk-based fixes and layered defenses.

Background for this topic.
Penetration testing is an authorized, time-bounded simulation of attacks against defined systems, applications, networks, cloud services, or users. Testers use realistic techniques to determine whether an attacker could gain access, escalate privileges, move between systems, or reach sensitive assets—not merely whether a scanner reports a vulnerability. The results show how weaknesses can be combined and whether preventive and detective controls work in practice.
Its value depends on a clear scope and threat model: an external test may examine exposed services and authentication, while an application test may target authorization flaws, APIs, and sensitive-data handling. Testing can disrupt systems or expose real personal or operational data, so written rules of engagement, test accounts, least-privilege access, monitoring, and protected findings are essential. Organizations should assign remediation owners, prioritize exploitable paths and business impact, and retest fixes; a penetration test complements, but does not replace, continuous vulnerability management.
