Definition[edit | edit source]

Access control technologies

ensure that only authorized users or systems can access and use computers, networks, and the information stored on these systems, and these technologies help to protect sensitive data and systems.[1]

Overview[edit | edit source]

Access control simplifies network security by reducing the number of

paths that attackers might use to penetrate system or network defenses. Access control includes three different control types: boundary protection, authentication, and authorization.[2]

Recent reductions in the price of biometric hardware have spurred logical access control applications. Fingerprint, iris, and speaker recognition are replacing passwords to authenticate individuals accessing computers and networks.
