    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    Good link DocBop. Myself, I keep the source web pages backed up (in version control) along with md5sums. So, I can check the current site, and if the checksums have changed, then I know I've been pwnd. In such a case I do this:

    0. Change root (and if necessary web-browser) password, along with disabling all sudo access to the root account.
    1. Take site off-line, with a "under maintenance" static page (read-only - not capable of modification by anybody).
    2. Figure out why I was vulnerable.
    3. Fix vulnerability and re-install known infected pages.
    4. Set up inotify to inform me if anything changes any of the pages on the site.
    5. Re-enable the site.

    This is a general roadmap.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
