The network device must terminate shared/group account credentials when members leave the group.

Description

<VulnDiscussion>A shared/group account credential is a shared form of authentication that allows multiple individuals to access the network device using a single account. If shared/group account credentials are not terminated when individuals leave the group, the user that left the group can still gain access even though they are no longer authorized. There may also be instances when specific user actions need to be performed on the network device without unique administrator identification or authentication. Examples of credentials include passwords and group membership certificates. The “mazu” account is the local Linux OS account created and used by the NetProfiler and Flow Gateway application for ownership of application, configuration, and data files stored on the appliance. Operations such as changing appliance settings and running reports on a cluster, as well as using backup/restore functionality rely on the existence of the “mazu” user. The account is required for proper operation of the solution. However, the ability to login to this account can be disabled on the Security Compliance page, as well as firewall rules can be used to restrict the remote access.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
