Security of Webserver

Are there anyways I can scan my servers IP and let is show me all the vulnerabilities i have...
I want to keep it secure.

Something like the linux software "dont be a dick"...
Is there an online version of this somewhere?

what kind of server is it? (what OS?)
Just as general advice, I would recommend asking this in the Linux Admin TA (or whatever is appropriate for your OS). This really isn't the type of thing that you can just test once then sit back and be sure everything is ok. It really requires a person to be on top of things -- otherwise there would be no such thing as a sys admin ;)

As for testing security vulnerabilities, I doubt anyone has a site or anything where you can do this -- that would basically be considered hacking, since anyone could use it to find out about servers that do not belong to them.

On the other hand, there are some well-known security holes that you can plug up (for example, you shouldn't allow direct ssh login as root; instead you should log in as another user, and then su to root -- that way someone has to find out two passwords instead of one to do real damage to your server). Here's a good place to get started (assuming you're on *nix):

but for reasons of security, as Matt mentioned, it will only scan the current computer so you cannot scan a remote IP.

Hope this helps.

Cool site Diablo ;)
BTW, you can try this on your remote server if you have SSH access:

prompt> lynx

I just tried on one of mine and it worked fine (you'll have to wait a while for it to finish downloading the page, but it should work eventually).

Great thanks guys!
I am running some tests now.

The thing is its a Windows server.
Behind a hardware firewall.
So things are looking good from the scans so far.

Run your own tests from home or a borrowed connection.

short answer: no
long answer: no
very long answer: there're dozents of tools to do partially what you asked for.
first you have to distinguish which kinds of vulnerabilities you whant to identidy: networ/OS or application or web application in particular
then you can select the proper tools
For network/OS the most common is nmap, but there're some commercial ones too.
For applications there's nmap and nessus, and the commercial ones again.
For web applications (as your PHP suggest) you need specialized tools. nmap/nessus are very weak in this area, whisker and nikto are good starters, but if you want a more complete scan you definitely need commercial ones like AppScan, WebInspect, ScanDo (just to mention a few). Then keep in mind that all of these tools only find simple flaws like XSS, SQL Injection , path traversal, file enumeration etc. etc.. None of them will find flaws in your application itself, like unadequate session management (session hijacking, session fixation, etc. etc.), logical flaws like posibility of user/password enumeration, or semantical like invalid SSL certs.

You see, my list may just name approx. 2% off currently know vulnerabilities, there is a long way to go to "all" as you asked for.
