Overview

Finding ID Version Rule ID IA Controls Severity
V-4116 3.101 SV-32358r2_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.
