Question
Which of the following statements best describes a "trap
door" in the context of computer security?Solution
A "trap door" (also known as a "backdoor") in computer security refers to a hidden or secret entry point in a program or system that provides access to the system without going through normal authentication methods. This entry point is intentionally created to allow unauthorized access to the system or software, often by those who designed or modified it. Trap doors can be used for legitimate purposes, such as for developers to access systems for maintenance, but they can also be exploited maliciously to bypass security measures. They are different from software bugs or errors that might cause a program to fail or behave unexpectedly.
