Most people treat the Recycle Bin, and emptying it, as the final word on a deleted file. This lab walked through why that assumption is wrong, and why both sides of that fact matter for a network defe
There's a meaningful difference between encrypting a file and encrypting a volume, and it's not just a matter of scale. A single encrypted file still reveals its own existence, its name, its size, rou

A wireless router arrives from the factory configured to work, not to be secure. Those are different goals, and the gap between them is exactly what this lab walked through: taking a consumer-grade TP
The Wazuh lab I'd worked through earlier caught an attack by watching a single host's own logs. This lab tackled a related but genuinely different problem: catching the same kind of attack by inspecti
Every firewall lab I'd worked through up to this point answered the same basic question: was a connection allowed or blocked? This lab asked a different one entirely: if an attack gets through anyway,

Most firewall thinking defaults to the network level: which IPs, which ports, which subnets. This lab worked at a different, more granular layer entirely, blocking internet access for one specific use
