Write 'did-you-know' article about auditd

[vpetersson]

Using auditd is really important for security. An overview for this can be found here. I want an article that expands on the recommended actions in greater details.

Things to include:

• What auditd is
• How it ties into the Linux Audit System
• The importance of combining this with remote logging

(Need to hook this up with NCSC/NIST references)
