apparmor.d VS lynis

If anyone want to look further into sandboxing applications on Linux, you can also look at AppArmor and the sandboxing features built into systemd.

I love this repository for bases for AppArmor profiles[1], really good work. Never found a repository as good for systemd, but there are a few around.

Then, categorize all your script zoo: maybe some script group want to only read the data, while some need to write, maybe one group needs to use certain set of binaries, and other group - others.

You could utilize some profiles from apparmor.d repo, but you should be slightly aware how it works (disclaimer: I'm the contributor).

Regardless, I wrote an AppArmor profile so it couldn't happen again.

Maintainer's response.

There is a project in early development: apparmor.d. Adopting some or all profiles will do the job. To use it smoothly, basic AppArmor knowledge is required. (I'm the contributor)

Dependent on the OS and Firefox distribution. I can advertise profile that I co-maintain. It uses non-standard tunables, which will require some README reading to get them into the system.

Red Hat based distros come preconfigured with a lot of SELinux policies. With AppArmor, you get basically nothing. There is a project I also contribute to from time to time, that gives you a lot more policies, but this is entirely out-of-tree (https://github.com/roddhjav/apparmor.d).

Linux has (free) tools to improve security and detect/remove malware: Lynis,Chkrootkit,Rkhunter,ClamAV,Vuls,LMD,radare2,Yara,ntopng,maltrail,Snort,Suricata...

What I would do in your place is run this https://github.com/CISOfy/lynis and follow some of the instructions.
