Authentication
Authentication is the process of verifying the identity of a user, system, or entity trying to access a resource. It confirms that they are who they claim to be, often by checking credentials like passwords or biometrics.
TECHNICAL DEFINITION
Authentication is a core cybersecurity mechanism within defense architectures, establishing and validating the claimed identity of a user, system, or network entity seeking access to protected resources or systems. It typically involves credential verification (e.g., passwords, biometrics, tokens) to prevent unauthorized access and ensure security posture.
BACKGROUND
Defense in depth is a concept used in information security in which multiple layers of security controls (defense) are placed throughout an information technology (IT) system. Its intent is to provide redundancy in the event a security control fails or a vulnerability is exploited.
