Advanced DNS Security

It protects Network with DNS-Level Defense. DNS Security focuses on safeguarding the Domain Name System (DNS) from various cyber threats, such as malicious DNS queries, DNS spoofing, DDoS attacks, and data exfiltration.

Common DNS Attacks & How Advanced DNS Security Protects Against Them

1. DNS Spoofing (Cache Poisoning)

  • Attackers manipulate DNS caches to redirect traffic to malicious sites.
  • Advanced DNS security uses DNSSEC to prevent tampering and ensures authenticity of responses.

2. DNS Amplification Attacks (DDoS)

  • Attackers exploit the DNS server to amplify the attack and target a victim.
  • DNS protection includes rate-limiting, filtering, and Anycast DNS to mitigate these threats.

3. Phishing & Malware Distribution

  • Malicious domains can be used to host phishing websites or distribute malware.
  • DNS filtering blocks these malicious domains before users can visit them.

4. DNS Tunneling (Data Exfiltration)

  • Attackers use DNS queries to send stolen data out of the network undetected.
  • Anomaly detection and DNS tunneling detection are employed to prevent data exfiltration through DNS.
