The MQ Appliance messaging server must protect against or limit the effects of all types of Denial of Service (DoS) attacks by employing operationally-defined security safeguards.
An XCCDF Rule
Description
<VulnDiscussion>DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. To reduce the possibility or effect of a DoS, the messaging server must employ defined security safeguards. These safeguards will be determined by the placement of the messaging server and the type of applications being hosted within the messaging server framework. There are many examples of technologies that exist to limit or, in some cases, eliminate the effects of DoS attacks (e.g., limiting processes or restricting the number of sessions the application opens at one time). Employing increased capacity and bandwidth, combined with service redundancy or clustering, may reduce the susceptibility to some DoS attacks. Note: IBM recommends that neither MQ server nor the MQ Appliance be placed in the DMZ where it could be vulnerable to DoS attacks. IBM recommends that this protection be provided by a firewall: https://ibm.biz/BdraMj For internal queue managers, You can restrict the total number of incoming connections by setting the MaxConnectionThreads property: https://ibm.biz/BdraMZ Satisfies: SRG-APP-000435-AS-000163, SRG-APP-000001-AS-000001</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
