System security

Hi guys, I have to make guidelines to secure our linux server, well i have found many checklist, but I am wondering if there is any tools that can tell us what aplication has been intalled on the server, well there is ps for the running process but we done have the version of the application, rpm -qa which is good but what if the application has been compile from source and not rpm -i.

The purpose of this is to identify the application running on the server, to unistall all unnecessary one and make a vulnerability assessment for the other, so maybe there is a script of application to identify all the application ?

Thanks in advance!!

hi,
you could try the command top ..... it shows all the cpu processes in real time

You're looking to check all installed applications on the system ?
Along with their versions ?

Or just want to know all the binaries on the system


Remember that they will usually go to specific locations

/usr/bin
/bin
/sbin
/usr/sbin
/usr/local/bin

etc
etc

Thx gyus for your advice, well I am looking for all the version of the application installed.... if you know any script of application who can do that coz it is too much effort to check the binarie and try to get the version one by one ...

Many thanks !!!
