Network servers, regardless of their application, must deal with a variety of security issues, attacks, and, in some cases, harm. These problems aren't specifically related to hardware or software, but they are problems. The security problems you should understand include the following:
- File integrity: File integrity means that data and program files have not been the target of an attack and modified in any way by an unauthorized person or function. An attacker, either internal or external, can compromise the integrity of a file purposefully or accidentally. Monitoring the integrity of stored data and programs should be a part of a standard monitoring procedure. File integrity monitor (FIM) software uses checksums and hashing to detect changes to a file. The most common hashing algorithm used is Message Digest 5 (MD5).
- Privilege escalation:...
