What are the challenges of identifying risks in encrypted DNS-over-HTTPS (DoH) traffic?

Identifying risks in encrypted DNS-over-HTTPS (DoH) traffic poses challenges due to the following reasons:

1. Visibility: Encryption in DoH traffic conceals domain queries and responses, making it harder for network security tools to inspect and analyze the data.

2. Security Blind Spots: Traditional security measures may not be able to detect malicious activities hidden within encrypted DoH traffic, leading to potential security blind spots.

3. Tracking and Monitoring: Monitoring user activity and tracking potentially harmful domains becomes difficult when DNS queries are encrypted, complicating threat detection and response.

4. Compliance and Governance: Organizations may face compliance challenges in terms of maintaining visibility and control over encrypted DoH traffic to ensure data security and legal compliance.

5. Mitigation and Response: Responding to threats or attacks originating from encrypted DoH traffic requires advanced security solutions capable of dealing with encrypted data and anomalies effectively.

Understanding these challenges is crucial in implementing comprehensive security measures to protect networks against potential risks associated with encrypted DoH traffic.
