External vs Internal Threat Posture
Treat external and internal threat surfaces as distinct problems. Perimeter defenses address outside actors. The internal surface includes staff devices, home networks, and family computers, and requires its own control set. The cost asymmetry is clear: extending the security umbrella to every endpoint is a fraction of incident response spend.
Ransomware Entry Points Persist
Paying a ransom, even a modest demand, does not end the event. Access credentials and vulnerability details are packaged and sold on darknet forums. The same vector gets reused or resold. Closure demands forensic identification of the initial penetration, hard closure of that vector, then expansion of monitoring, training, and scheduled penetration testing across the extended estate.
