I wish there was a list of those tools that would alert a webmaster (red flag) for potential problems.
The archives (i. e., old topics) at Webmaster World are archived by multiple search engines.
You just need to become aware of the options for searching those old pages.
Once gain, the questions that you seem to be asking have been discussed here time and again.
You simply need to review these old discussions and not expect an instant notification of intrusion and a solution. . .and all within the same response or email.
