The Windows 2012 DNS Server must restrict incoming dynamic update requests to known clients.
Description
Discussion Text
Limiting the number of concurrent sessions reduces the risk of Denial of Service (DoS) on any system.
A DNS server's function requires it to be able to handle multiple sessions at a time so limiting concurrent sessions could potentially cause an impact to availability.
Primary name servers need to be configured to limit the actual hosts from which they will accept dynamic updates and from which they will accept zone transfer requests, and all name servers should be configured to limit the hosts from/to which they receive/send zone transfers. Restricting sessions to known hosts will mitigate the DoS vulnerability.
