Server logs- how to interpret- how to tell what is being accessed and if it has been compromised
I was wondering if anyone can tell me how to interpret my server logs on Server 2008 Standard? I always see these ip addresses hitting it and I block out the ones I do not recognize or search for and find out they are bots. I just do not know if they have accessed or compromised any files. My site is running perfectly and I see these hits coming from all over the world. How can I tell what if anything is being hit or what files are being corrupted or 'owned' if you will. I am going to launch soon and am looking into server hardening but its complicate and I am a newbie.
This is was one I found to be an attack from yesterday- How can I tell what may have been compromised?
