Masquerading

Masquerading is a cybersecurity threat in which an unauthorized entity assumes the identity of a legitimate user, system, or application to bypass security controls and gain unauthorized access to protected resources. Attackers employ tactics such as stolen credentials, session hijacking, IP or MAC address spoofing, and exploitation of weak authentication mechanisms to disguise themselves as trusted entities. The objective is to leverage this false identity to access sensitive data, execute unauthorized transactions, modify system configurations, or deploy malware—all while evading detection.

Defending against masquerading requires a layered security approach that includes strong authentication measures such as multi-factor authentication (MFA), robust authorization policies, secure session management, and adherence to secure coding practices in application development. Organizations should also deploy advanced anomaly detection and behavioral analytics systems capable of identifying irregular activity patterns that may indicate impersonation attempts, ensuring that deceptive actors are detected and neutralized before they can cause significant damage.
