  "bluf": "MITRE ATT&CK T1599 (Network Boundary Bridging) is an Enterprise Defense Evasion technique. Adversaries may bridge network boundaries by compromising perimeter network devices or internal devices responsible for network segmentation. Breaching these devices may enable an adversary to bypass restrictions on traffic routing that otherwise separate trusted and untrusted networks. Devices such as routers and firewalls can be used to create boundaries between trusted and untrusted networks. ATT&CK documents 1 sub-technique: T1599.001 Network Address Translation Traversal. Affected platforms: Network. MITRE-documented mitigations include M1032 Multi-factor Authentication, M1027 Password Policies, M1026 Privileged Account Management, M1037 Filter Network Traffic, M1043 Credential Access Protection. The Center for Threat-Informed Defense maps this technique to NIST SP 800-53 Rev 5 controls AC-02, AC-03, AC-04, AC-05, AC-06, CA-07, CM-02, CM-05.",
