How to solve
Every system has its own role to support the business. Depending on the data stored, or transported, the system needs controls in place to detect malware. A web server would benefit from detecting PHP backdoors, where a mail server would benefit from detecting a wide variety of viruses, worms, and trojans.
It is suggested to perform regular malware scanning.
Generic virus detection
Use ClamAV or a commercial alternative
- Rootkit Hunter (rkhunter)
Malware detection for web servers
- Linux Malware Detect (LMD)
