Re: [suse-security] SuSE 8.1 hacked?



A system is only as secure as the administrator makes it.  Your message is too vague to give you any sort of reasonable answer.  For all I know you allowed root to ssh into your box and root had no password, or an easily guessed password.  I could keep guessing why someone hacked your box but  that would be useless.

make sure your box is up to date, you only have the services which you need running on it, you understand the security issues with each service, you have a good security policy in place.

If you do nt understand a service, or how to secure it, do not open it up to the wild.  Play with it and learn it on a private box and THEN implement it with a good security policy.
