MAR

MAR (Modify and Remember) is a type of security method used primarily in the field of computer programming. It is an acronym for Modify and Remember, referring to a system in which a user or program is given two different versions of a given program and is responsible for storage of both.

MAR is based on the principle of dynamic access control. In order to use a MAR system, a user must first be granted access to both versions of the program. Then the user can make modifications to the program and commit the changes to the main program’s source code. Once committed, the program can then be reconfigured and used in the way it was originally intended.

Most commonly, MAR systems are used in the field of software engineering, where they are used as an alternative to traditional source control systems. MAR is an efficient way to keep track of the differences between versions of code over time, and to quickly debug or fix any errors that may arise from the modifications.

MAR is also used in encryption and security applications, where it offers a layer of protection against malicious attacks. By segregating the changes between versions of the program, a MAR system prevents attackers from accessing data that they are not meant to have access to.

Overall, MAR provides a simple and secure way of making modifications to a given program without compromising the security of the system. It is a valuable tool for software engineers and security professionals.
