looking for security hardening guide
 

hello. just install 31 and am looking for security hardening guide. the fedora site documention doesn't seem to have what i'm looking for (like disabling unneeded services, etc.,). appreciate if someone who have done it or have an article could point me in the right direction.

Since Fedora is a test distribution of Red Hat, do an online search for 'securing Red Hat' which will give you numerous sites, many at the Red Hat site.

We can help with specific things, but asking for 'security' is like asking "how high is up?". Everything depends on the environment you're in, users, application(s), etc., etc....a thousand different things.

You mention disabling unneeded services....but only YOU can tell anyone what those would be. If you need to print, you obviously need CUPS or a printer service, and if you don't, that would be unneeded. Same for anything else; only you are going to have that answer. Past that, you need to think about what you're trying to accomplish. If you have a laptop, and want it to be more secure on the Internet, that's far different than an in-place server, behind a firewall/DMZ on a monitored corporate network.

Security is a process; there are no guides, past anything basic. Tip guides are abundant:
https://www.tecmint.com/linux-server...security-tips/
https://www.cyberciti.biz/tips/linux-security.html

..but again, they're guides, and shouldn't be taken as ALL you need to do.

This search suggests that what you are looking for is available for both Redhat and fedora.
