Adaptive DNS Security To Ensure Service Continuity and Data Protection
Secure DNS Services Require A Purpose-Built Security Solution
The nature of DNS threats is quickly evolving and DNS attacks have become highly sophisticated based on distributed, multi-vector and multi-stage assault modes. Signature-based security solutions such as firewall, anti-DoS or IPS are not adapted to efficiently ensure DNS services availability and integrity. They have proved to be insufficient against most DNS attacks – such as DNS hijacking, amplification and reflection attacks, and DNS flooding – and even worse, present a high risk of blocking legitimate clients (false positives).
Restricted DNS analytics capacity and basic blocking-based countermeasure imply serious security limitations and risks: Business downtime, customer data or intellectual property theft, damaged reputations and embezzlement of money.
A modern DNS security system must be agile enough to adapt its DNS protection mechanisms to mitigate the risk of false positives, while safeguarding data and ensuring DNS service integrity and continuity to legitimate clients.
