DNS Protection and Challenges

What is DNS Protection?

Given that DNS is a critical component of internet functionality, it is a frequent target for cyberattacks. Attackers may exploit vulnerabilities in DNS to redirect traffic, steal data, or launch further attacks.
By implementing robust DNS protection, organizations can significantly reduce the risk of successful attacks, safeguard sensitive information, and maintain operational continuity.
DNS protection also ensures that unauthorized users cannot exploit the DNS infrastructure to carry out harmful actions such as data exfiltration or malware distribution.

The silent DNS challenge: Exposing invisible threat pathways

Adversaries use DNS protocol to keep their communications covert and evade detection. In particular, modern malwares use DNS to establish a command and control channel and facilitate exfiltration to take advantage of the fact that DNS traffic is not typically analyzed by firewalls and IDS/IPS devices.
Seceon OTM Platform

Stop attackers who hide in DNS

Detect DGA domains, DNS tunneling, fast-flux infrastructure and DDoS amplification, then block high-confidence threats automatically.

DGA Detection and Prediction Engine

Catch malware domains before they are listed

Identifies and predicts malware command-and-control hostnames generated by domain generation algorithms, before they are catalogued, using entropy and n-gram analysis.

Illustrative example.

DNS Tunneling alert

Data hidden in queries

Flags data encoded in DNS queries and responses using query length and entropy analysis.

Suspicious domains

Watches for infrastructure attackers use to stay ahead of blocklists.

Fast-fluxNewly registered domainsDNS-over-HTTPS bypass

SNOED

Newly observed domains

Spots domains with unusual traffic spikes across customers, signaling campaign infrastructure before any external IOC is published.

DDoS alerts

Floods and amplification

Alerts on DDoS conditions, including amplification attacks that abuse third-party services to multiply traffic.

AmplificationTCP SYN floodICMP flood

Proactive Low-Regret Blocking Model

Block before confirmation

Uses probabilistic risk scoring to block high-confidence suspicious indicators before external validation is complete, reducing dwell time.

Malicious domain intelligence

IOCs from 100+ sources across categories including C2 servers, DGA domains, phishing domains, botnet IPs and typosquatting domains.

Containment through SOAR

Cross-Customer Global Correlation Engine

One detection protects everyone

When suspicious activity is detected at one site, correlated indicators propagate to protect all customers. New intelligence is also re-checked against historical telemetry.
