Homonym: Back Doors (Entrances)
A "Back Door" in computer security refers to a method that allows unauthorized access to a system or software, bypassing normal authentication processes. This can be intentionally created by developers for maintenance purposes or maliciously installed by hackers to exploit vulnerabilities.
Back doors can exist in various forms, such as hidden features in software or compromised hardware. They pose significant risks, as they can lead to data breaches and unauthorized control over systems. Organizations often implement security measures to detect and close these back doors to protect sensitive information and maintain system integrity.
