Submitted my proposal for the @nluug conference in May! It is about #systemd and how to leverage it for improved #LinuxSecurity.

Do you also have something to share about #OpenSource, #OpenStandards or anything related? Submit your proposal: cfp.nluug.nl/nluug-voorjaarsco

If you are a speaker at #FOSDEM or #cfgmgmtcamp, then most likely you are a good match 😉

Another improvement: on the command pages is now a list of tools that are related to the current command.

With this functionality you can find an alternative or a related tool that might just provide you with the right information or perform the task at hand. Also great for discovering additional tools for your #linux toolkit.

Example: linux-audit.com/system-adminis

Linux Audit · capsh commandThe Linux command capsh provides a capability shell wrapper to set, test, and assist in debugging issues related to Linux capabilities.

With #systemd extending the unit settings, I can't stay behind and add them to the blog. Updated list: linux-audit.com/systemd/settin

This time the PrivatePIDs setting has been added. It allows a service to run in a separate PID namespace. Yes, including PID 1!

linux-audit.com/systemd/settin

When I got my hands on a #Linux system running 257, I will definitely be testing that. Shame it can't be added to services with the type of 'forking', but still, it might be useful for those others.

Linux Audit · Settings for systemd unitsSystemd units can be configured with a lot of fine-grained settings. This overview shows which settings are available and what they do.

Using #nginx and #systemd on a system is more common nowadays. Did you already check out this #linuxsecurity hardening profile for nginx?

linux-audit.com/systemd/harden

It's a set of parameters that sandbox nginx. The best part of implementing is that you really start to learn what a process does or does not need very quickly. Good for your #linux knowledge 💪

Also interesting, unit settings: linux-audit.com/systemd/settin

If you implemented the profile, love to hear how you like it! Anything missing?

Linux Audit · Nginx hardening profileHarden the nginx configuration with the help of this predefined profile that implements systemd sandboxing capabilities and restricting resources.

Very very... scary news in #Linuxsecurity

Seems like the at least one of the devs that contributed to #xz in the last 2 years has intentionally placed a backdoor in the package, shipped on almost all Linux distros.

arstechnica.com/security/2024/

(seems like this is already blowing up on mstdn)

Ars Technica · Backdoor found in widely used Linux utility breaks encrypted SSH connectionsMalicious code planted in xz Utils has been circulating for more than a month.
