| SSAC Advisory on DDoS Attacks Leveraging DNS Infrastructure (R-4) | SAC065 |
|
Description:
Authoritative DNS server operators should investigate deploying authoritative response rate limiting. This involves:
a. Investigate mechanisms to deter DNS amplification attacks (e.g., Response Rate Limiting (RRL) in DNS server software), and implement those that are appropriate for their environment;
b. Encourage DNS software vendors to provide such capabilities; and
c. Frequently review the state of the art of such mechanisms and update their environment as necessary.
