The system must be configured to ignore NetBIOS name release requests except from WINS servers.


Overview

Finding ID Version Rule ID IA Controls Severity
V-4116 WN08-SO-000043 SV-48126r1_rule ECSC-1 Low
Description
Configuring the system to ignore name release requests, except from WINS servers, prevents a denial of service (DoS) attack. The DoS consists of sending a NetBIOS name release request to the server for each entry in the server's cache, causing a response delay in the normal operation of the servers WINS resolution capability.
