CompTIA Security+ Exam Prep

Answer: C - Maintenance hooks allow for easy maintenance by means of a random sequence of keystrokes that provide access into software. Maintenance hooks are a type of backdoor. They are instructions within software that only the developer knows and can invoke to give easy access to the code. They allow the developer to view and edit the code without having to go through regular access controls. During the development phase of software this is useful, but if they are not removed before the software production, they are a security issue.
