SOC Hardening & Defensive Containment
Defending enterprise perimeters against campaigns staged by TA547 requires defense-in-depth posture enforcement:
- Egress Filtering & C2 Interception: Enforce strict egress inspection and block communication to unclassified external IP blocks, fast-flux proxy relays, and dynamic DNS providers.
- Credential Isolation & Privileged Access Management: Enforce FIDO2 hardware MFA across all administrative and VPN entry points to prevent session token hijacking and password reuse.
- Attack Surface Reduction & Patch Velocity: Prioritize remediation of public-facing edge network appliances (VPN concentrators, web servers, file transfer appliances).
