Pros:
- This program provides methods of checking for common procedural errors.
- COPS collect outputs and either mails the information to the admin or logs it in.
Cons:
- It could be modified by an intruder or even take advantage of its features.
- It is meant to tighten the security, not a tool to be used to find security flaws. It does not directly correct errors found.
