Anycast DNS Hardening
Resilient Topographies, Zone File Audits & Domain Isolation
Resilient DNSSEC Topography
Domain configuration lies at the very heart of an organisation's transit vector. A compromise here redirects all application traffic, email transit, and client verification loops instantly.
SiteCraft designs robust Anycast DNS distribution infrastructures. Instead of relying on vulnerable unicast name servers, we distribute zone files across multiple globally dispersed nodes, ensuring zero single-point-of-failure vulnerabilities. By signing our records with DNSSEC (Domain Name System Security Extensions), we provide mathematical proof of origin, rendering DNS cache poisoning and BGP redirect hijacking completely ineffective.
Physical Analogy: Think of a web application firewall like a concrete boundary wall surrounding an office building. Security guards stand at the gate, checking visitors' badges and communicating over the radio to verify authorization before anyone is allowed inside.
Domain Defence Systems:
- Anycast Redundancy Topology: Spreads query resolution workload to prevent denial-of-service compromises.
- Registrar Lockdown Auditing: Configuring multi-layered operational locks to stop malicious administrative takeover attempts.
- Perfect Zone File Integrity: Implementing strict CAA records, DMARC alignment, and cryptographic verification loops.
Domain Hardening Checklist
- Distributed global Anycast name servers
- Full DNSSEC signature origin validation
- Rigid SPF, DKIM, and DMARC alignments
- Multi-factor registrar lock configurations
- Continuous zone file integrity scanning
