Misfeasor - legitimate user who makes unauthorized accesses or misuses his privileges (inside)
Clandestine user - seizes supervisory control to evade auditing and access controls or suppress audit collection (inside|outside)

OVERVIEW

System Intrusion refers to a type of attack, commonly known as a "hacking attack," on a computer system. It can also be initiated by an insider who abuses their privileges on the system. This attack is characterized by actions such as deleting, modifying, or adding files, creating additional accounts, and using disk or memory without proper explanation.
