SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps security engineers evaluate the security and integrity of DNS infrastructure, including DNSSEC deployment, resolver validation, and filtering practices.

Core Features & Use Cases

  • DNSSEC Configuration Analysis: Checks whether authoritative zones are signed correctly with strong algorithms and proper key management practices.
  • Resolver Validation Evaluation: Verifies if recursive resolvers have DNSSEC validation enabled and trust anchors are current.
  • Encrypted DNS Assessment: Reviews the deployment of DNS over TLS and HTTPS, ensuring client and resolver privacy.
  • DNS Filtering & RPZ Inspection: Examines Response Policy Zones and protective DNS services for malicious domain filtering and policy enforcement.
  • Exfiltration Detection Readiness: Assesses if DNS query logging and anomaly detection capabilities are implemented to identify covert exfiltration channels.
  • Threat Detection & Policy Enforcement: Evaluates infrastructure against best practices per NIST and CIS controls for DNS security.

Quick Start

Review your DNS configurations by analyzing the files and settings across your authoritative servers, recursive resolvers, and filtering services.

FAQPage Schema
How do I perform a DNS security assessment on my infrastructure?

A DNS security assessment analyzes configuration files across authoritative servers, recursive resolvers, and filtering services to detect vulnerabilities and ensure compliance with industry standards.

What is DNSSEC configuration analysis and how does it validate zone signing?

DNSSEC configuration analysis verifies that authoritative zones are correctly signed using strong algorithms and proper key management practices to ensure DNS data integrity.

How do I check if my recursive resolvers have DNSSEC validation enabled?

Resolver validation evaluation verifies if recursive resolvers have DNSSEC validation enabled and confirms that trust anchors are current to prevent response spoofing.

Can I assess DNS over TLS and HTTPS deployment for client privacy?

Encrypted DNS assessment reviews the deployment of DNS over TLS and DNS over HTTPS to ensure client and resolver query privacy is properly enforced.

How do I detect DNS exfiltration channels in my network?

Exfiltration detection readiness assesses if DNS query logging and anomaly detection capabilities are implemented to identify covert data exfiltration channels.

What is the best way to inspect DNS filtering and Response Policy Zones?

DNS filtering and RPZ inspection examines Response Policy Zones and protective DNS services to verify malicious domain filtering and policy enforcement effectiveness.
