Linux input for process monitoring (similar to Windows Sysmon)

[ejwade]

We're looking for a tool that does the same thing as Windows Sysmon (Sysinternals), but for Linux. The problem with ps and other process monitoring inputs in the Linux TA is the interval. If a process launches and closely quickly, an interval capture will missed it. We need something that will write a log whenever a process is created, preferably with the command launching the process.

Any input is appreciated.

Good afternoon,

I did some brief research and testing with Linux systems for the same reasons; We were looking for command-line capture and process execution within our Linux environment. The best we came up with is Auditd. This provided close to the same results as Sysmon (i.e. if someone ran a command in command-line). The way it operates though is different to Sysmon where when you configured Sysmon and installed it, it began logging right away. With Auditd we had to create "rules" to look for activity.

I hope this answers your question.

Have a wonderful day!

Here are some references that I have come across regarding auditd and creating the rules.

You can achieve this using Linux auditd, please check with your Linux system administrator to configure auditd on Linux server and then monitor auditd.log file in Splunk.

@harsmarvania57 That's good advice. We've been exploring auditd; specifically EXEVCE system calls. Thanks for the suggestion!
