Page 6 of the DSE Cybersecurity knowledge center, with source-backed guidance and practical next steps.
Source-backed guidance for identity, vulnerability reduction, ransomware readiness, detection, response, and recovery.
Cyber resilience is an engineered ability to continue mission-essential outcomes through attack and compromise—not a synonym for prevention or backup. Define what must endure, then design and test for anticipation, resistance, recovery, and adaptation.

Windows devices can keep booting after the 2011 Secure Boot certificates expire yet miss future early-boot protections. Inventory status, update OEM firmware, pilot by hardware family, and verify the 2023 trust chain with evidence.

Microsoft now plans to disable SMTP AUTH Basic authentication by default for existing Exchange Online tenants at the end of December 2026. Find every sender, choose a supported replacement, pilot it, and prove the legacy path is quiet.

SMB over QUIC protects Windows file access with TLS 1.3 over UDP 443, but Windows clients can still prefer TCP and external authentication can fall back to NTLM. Prove transport, identity, certificates, and renewal before production.

RPKI lets resource holders authorize which ASN may originate a prefix and lets operators validate BGP origins. It does not validate the full AS path or prove a route is benign. Build careful ROAs, redundant validators, policy, and monitoring.

Kubernetes Pod Security Admission can enforce privileged, baseline, or restricted profiles by namespace while audit and warn modes expose violations first. Govern labels, policy versions, exemptions, and controller-created Pods as one system.

GitHub Actions can exchange a GitHub-issued OIDC token for a short-lived cloud credential instead of storing a long-lived key. The security gain depends on strict trust claims, least-privilege cloud roles, protected environments, and tested revocation.

Azure Policy exemptions preserve compliance visibility while recording a Mitigated or Waiver decision, but expiration is optional and the object remains after expiry. Treat each exemption as a governed, time-bound risk record.

Terraform state binds configuration to real infrastructure and can contain sensitive data. A team needs controlled remote storage, supported locking, restricted access, serialized changes, versioned recovery, and a tested process for failed writes.

NTLM is deprecated and Microsoft is preparing Windows for stronger Kerberos-based authentication. A safe retirement starts with auditing real use, assigning every dependency, repairing its cause, and testing progressively tighter blocking.
