Linux logging on Splunk

[mksingh]

I want to know industry standard for Linux system logging for security purpose. What files needs to be logged and how to capture command line commands logging?

Hi mksingh,

That is quite a broad question/topic, but I would recommend you start here:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security_Guide/chap-sy...

The actual configuration and logs you monitor will depend heavily on the flavor of the nix system (RHEL, HPUX, AIX), but as RHEL is mostly what you might see...check out the docs on the Linux audit system.

A couple good resources here as well:

Your best bet would be to consult a security and compliance SME in your field to ensure you are capturing what matters to securing the systems in use.
