Information

This policy setting allows a user to adjust the maximum amount of memory that is available to a process. The ability to adjust memory quotas is useful for system tuning, but it can be abused. In the wrong hands, it could be used to launch a denial-of-service (DoS) attack.

The recommended state for this setting is: Administrators, LOCAL SERVICE, NETWORK SERVICE.

Note: A Member Server that holds the Web Server (IIS) Role with Web Server Role Service will require a special exception to this recommendation, to allow IIS application pool(s) to be granted this user right.

Note #2: A Member Server with Microsoft SQL Server installed will require a special exception to this recommendation for additional SQL-generated entries to be granted this user right.

A user with the Adjust memory quotas for a process user right can reduce the amount of memory that is available to any process, which could cause business-critical network applications to become slow or to fail. In the wrong hands, this privilege could be used to start a DoS attack.

Solution

To establish the recommended configuration via GP, set the following UI path to Administrators, LOCAL SERVICE, NETWORK SERVICE :

Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Adjust memory quotas for a process

Impact:

Organizations that have not restricted users to roles with limited privileges will find it difficult to impose this countermeasure. Also, if you have installed optional components such as ASP.NET or IIS, you may need to assign the Adjust memory quotas for a process user right to additional accounts that are required by those components. Otherwise, this countermeasure should have no impact on most computers. If this user right is necessary for a user account, it can be assigned to a local computer account instead of a domain account.
