I have been searching for logs specific to file deletion from Linux servers. I've searched audit logs but do not get any relevant logs . I have also searched in auth folder. Can anyone help me identify which folder to look in for logs that are being ingested into Splunk?
If you can't use something like inotify to update you. The next best thing i can think of is to monitor the history command for any time the rm command is called. That is the next best thing i can think of. This way you can setup a search for anytime the remove command is used and this can be a report or an alert based on the condition you would like
It is unlikely this is being logged by default on a standard *nix system. Your sysadmins should be able to set something up for you (have a google, it depends on your distribution) and then its just a matter of adding those logs to Splunk.
If the files are on some kind of filer that may be a different matter, again it will depend on the vendor.
