Sent here too from the Harvard Cybersecurity course. This video really helped me because, the Wikipedia article just got me confused.

[@ProTechShow]

Glad to hear it was helpful

Interesting video. But
"Patch patch patch!" doesn't resonate too well with what's happened with XZ/LZMA a few days ago

[@ProTechShow]

On the contrary, anyone who installed an affected distro last week and hasn't patched now has a dangerous backdoor. Patching is exactly what they need to do.

[@hugues90]

@@ProTechShow I beg to differ. The version affected was the latest. Currently, the only way for someone to "patch" their version is to actually *downgrade* to a previous release known not to be infected. Fortunately, no stable Linux distro had included the package yet, AFAIK.

[@ProTechShow]

@hugues90 that is not the case. Debian (unstable) and Kali were both affected and released patches almost immediately.
Patching regularly might occasionally mean you get a bad update; but it also means you'll get the fix quickly, too.
If you don't patch, you won't avoid vulnerabilities - you simply guarantee the ones you have don't get fixed. The older the vulnerability, the more likely it is to be exploited.

You're welcome

[@leandrosly]

how can you channel have so few likes? very usefull videos! tks!

[@ProTechShow]

Thanks! This was an early one when I had a handful of subs, and it doesn't seem to be a topic people are searching for so it's not had many views. I'm glad someone enjoyed it though!

[@kaliniliev447]

Very well explained ! cs50 cybersecurity did use a good source.

[@ProTechShow]

Thanks 🙂
