Is Linux truly secure, or are we clinging to a myth born in the ‘70s? This video delivers a brutal but honest verdict: for the average user, Linux security is a dangerous illusion.

We expose how the very tools meant to protect — from iptables to LSM — are often too complex, too fragile, and architecturally outdated. It's not just about misconfigurations: it's about flawed design choices baked into the system. Security in Linux isn't automatic — it demands deep expertise. And that makes it inaccessible and unsafe for most.

We back this up with real academic research, measurable performance limitations, and cutting-edge alternatives like formal verification, eBPF, declarative policies, and Zero Trust architectures.

This is not a rant — it’s a call for awareness. Based on peer-reviewed papers and verified benchmarks. Full references below.
