A penetration test, or pen-test, is a simulated cyberattack against your computer system to check for exploitable vulnerabilities. These vulnerabilities may exist in operating systems, services and application flaws, improper configurations or risky end-user behavior. Such assessments are also useful in validating the efficacy of defensive mechanisms, as well as, end-user adherence to security policies.
Information about any security vulnerabilities successfully exploited through penetration testing is typically aggregated and presented to IT and network system managers to help those professionals make strategic conclusions and prioritize related remediation efforts. The main objective of penetration testing is to determine security weaknesses. A pen test can also be used to test an organization’s security policy compliance, its employees’ security awareness and the organization’s ability to identify and respond to security incidents.
