FRIEND
The article provides a defensive technique (ACL implementation) that helps defenders secure their networks against external threats.
Defender Context
Defenders should consider implementing robust and simplified ACLs to segment their networks and restrict access, especially for IoT devices which are often less secure. This approach helps minimize the attack surface and prevent lateral movement by adversaries.
