Zero trust, one request at a time
4 of 10 open
Where a request comes from earns it nothing: be the policy engine, plant an attacker, relay a login.
Security in the age of AI
4 of 7 open
Against attackers that move in seconds, I argue only constant monitoring keeps up: the hours nobody is watching, with sources.
