SELinux and confined users, make the Linux Desktop more secure - eviltoast
Security enthusiasts wanted: from beginners up to SELinux experts to make up the SELinux "Confined Users (SIG)" to foster Fedora's security capabilities

SELinux provides a strong security measure that can make an SELinux-enabled operating system a type of “fortress”: the so-called “confined users” [1] [2] [3], which add security and isolation capabilities that are in several respects comparable to containers but without many of their restrictions in GUI use cases (this topic is focused on desktop use cases, not server, infra, and such). By default, SELinux does not enforce much within user accounts but only around them. But in graphical desktop...

    Really good points from here:

    The “many eyes” theory is dead since the NSA backdoor in OpenSSL clearly showed how delusional that belief is. SELinux has never been audited by any trustworthy truly US-independent entity, making it nearly as untrustworthy as closed source. On top of that, there is always The Underhanded C Contest, proving that looking at the source is not enough. You need to be an expert who can detect underhanded backdoors too. – Evi1M4chine Feb 3, 2018 at 13:05

    I don’t think the NSA’s official mission is a good reason to believe it wouldn’t add backdoors. The agency considers American citizens to be adversaries, not beneficiaries of its operations. – augurar Oct 21, 2014 at 4:23
