Cyber Resilience Briefing — April 7, 2025
Cloud-native threat hunting now requires deep observability on serverless and edge workloads; Zeph Tech maps priorities to MITRE D3FEND and CIS Control 8.
Executive briefing: Serverless functions, managed containers, and edge nodes expand the attack surface far beyond traditional hosts. Zeph Tech is standardising telemetry capture, hunt hypothesis backlogs, and remediation workflows so SecOps teams can align their playbooks to MITRE D3FEND countermeasures and CIS Control 8 expectations.
Key industry signals
- Technique catalogues are mature. MITRE D3FEND now maps defensive techniques to offensive behaviours, giving hunters a common language for hardening serverless pipelines.
- CIS Control 8 refresh. The CIS Controls v8 guidance emphasises inventorying and monitoring enterprise assets, including ephemeral workloads that previously escaped asset management scopes.
- Serverless exposures documented. The OWASP Serverless Top 10 captures event injection, privilege escalation, and data leakage paths that hunters must model within hypothesis development.
Control alignment
- MITRE D3FEND. Map hunts to techniques such as Credential Hardening (D3-CH) and Network Segmentation (D3-NS) so coverage aligns with proven countermeasures.
- CIS Control 8.2 and 8.7. Automate asset discovery across Kubernetes, container registries, and serverless runtimes, and log administrative actions for detection engineering.
Detection and response priorities
- Alert on unusual spikes in serverless invocations tied to privileged identities or new environment variables, indicating token replay or injection attempts.
- Baseline edge device process lists and outbound traffic; flag binaries or destinations that deviate from approved manifests.
Enablement moves
- Run joint hunts between cloud engineering and security to validate telemetry coverage, then capture repeatable steps within an internal playbook library.
- Publish remediation templates that translate hunt findings into infrastructure-as-code guardrails and CI/CD policy updates.
