A logic flaw in Cisco ASA/FTD’s SSL VPN handling lets an unauthenticated attacker send a crafted connection request and force the firewall to reload, knocking out VPN and firewall service.
Two things live here.
Advisories — a running brief on the vulnerabilities that matter to people running network and edge infrastructure. Every CISA KEV addition, plus critical flaws in firewalls, VPN gateways, routers and management planes. What it is, what to do about it, and what to tell your leadership — in that order. Sources and the checks every post passes are set out in the methodology.
The workshop — longer write-ups from a home lab: virtualisation, self-hosted AI image and speech generation, build automation, and the things that broke on the way. Slower, and considerably less urgent.

From the workshop
Three AI reviews of the same project, and where they disagreed
I gave three AI models the same data about a project of mine and asked each, separately, why it was not growing. The consensus turned out to be the least useful part.
Auditing a homelab after it breaks: what the documentation got wrong
After a failure I went through my own infrastructure line by line and compared it to my notes. Six things were wrong, and all six were wrong in the same direction.
