Troubleshooting Methods
You need to check both the users and applications of your Linux servers.
- Users: Check processes and networks and view the users of the running processes. Check for abnormal files in the username directory under the /home directory, and check for abnormal logins and brute-force attacks.
- Applications: Check for abnormal files in application process directories.
For details, see Troubleshooting Process.
