CISO Architecture: Strategic Resilience: Moving Beyond DNS Filtering
Three-pillar executive guidance covering threat surface exposure, control isolation, and operational roadmaps.
In light of the Underminr protocol, architects must transition from DNS-based security to 'Identity-Centric Infrastructure.' This involves: 1. Implementing TLS Inspection (Break-and-Inspect) at the edge to validate SNI-Host header matching. 2. Adopting JA4 fingerprints to identify and block non-standard TLS clients used by C2 frameworks. 3. Moving to 'Private Package Repositories' (e.g., Artifactory, Sonatype) for all PHP, npm, and Python dependencies to prevent supply chain poisoning. 4. Enforcing 'Signed Commits' and 'Attestations' (SLSA) for all internal and third-party code. The goal is to create a 'Verifiable Supply Chain' where trust is earned through cryptographic proof, not assumed based on domain reputation.
