The Windows DNS Server must restrict individuals from using it for launching denial-of-service (DoS) attacks against other information systems.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-259395	WDNS-22-000067	SV-259395r961152_rule		Medium

Description
Applications and application developers must take steps to ensure users cannot use an authorized application to launch DoS attacks against other systems and networks. For example, applications may include mechanisms that throttle network traffic, so users are not able to generate unlimited network traffic via the application. Limiting system resources that are allocated to any user to a bare minimum may also reduce the ability of users to launch some DoS attacks.
