The IBM Security zSecure Suite products must use an external security manager (RACF, ACF2, or TSS) for all account management functions.

An XCCDF Rule

Description

<VulnDiscussion>Enterprise environments make application account management challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. A comprehensive application account management process that includes automation helps to ensure accounts designated as requiring attention are consistently and promptly addressed. Examples include but are not limited to using automation to take action on multiple accounts designated as inactive, suspended, or terminated or by disabling accounts in noncentralized account stores, such as multiple servers. This requirement applies to all account types, including individual/user, shared, group, system, guest/anonymous, emergency, developer/manufacturer/vendor, temporary, and service. The application must be configured to automatically provide account management functions, and these functions must immediately enforce the organization's current account policy. The automated mechanisms may reside within the application or be offered by the operating system or other infrastructure providing automated account management capabilities. Automated mechanisms may be composed of differing technologies that when placed together contain an overall automated mechanism supporting an organization's automated account management requirements. Account management functions include assignment of group or role membership; identifying account type; specifying user access authorizations (i.e., privileges); account removal, update, or termination; and administrative alerts. The use of automated mechanisms can include, for example, using email or text messaging to automatically notify account managers when users are terminated or transferred, using the information system to monitor account usage, and using automated telephonic notification to report atypical system account usage.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Ensure READ access to zSecure functional resources is restricted to the appropriate staff members.

READ access can be given to security administrators (domain level and decentralized), security batch jobs that perform ESM maintenance, and trusted STC users.

The following commands are provided as a sample for implementing zSecure functional resource controls:
rdef xfacilit resource_profile_protecting_zSecure_CKF_ resource  uacc(none) owner(zSecure owner) 
pe resource_profile_protecting_zSecure_CKF_ resource class(XFACILIT) id(SECAAUDT, SECBAUDT, SECDAUDT, TSTCAUDT) access(READ)

rdef xfacilit CKNADMIN.TONODE.<node-name>  uacc(none) owner(zSecure owner) 
pe CKNADMIN.TONODE.<node-name>  class(xfacilit) id(SECAAUDT, SECBAUDT, SECDAUDT, TSTCAUDT) access(READ)

rdef xfacilit CKNADMIN.FROMNODE.<node-name>  uacc(none) owner(zSecure owner) 
pe CKNADMIN.FROMNODE.<node-name>  class(xfacilit) id(SECAAUDT, SECBAUDT, SECDAUDT, TSTCAUDT) access(READ)

rdef xfacilit CKNDSN.<dstype>.<node-name>.<systemname>.ACTIVE  uacc(none) owner(zSecure owner)

rdef xfacilit CKR.ACTION.**  uacc(none) owner(zSecure owner) 
pe CKR.ACTION.** class(xfacilit) id(SYSPAUDT, SECAAUDT, SECBAUDT, SECDAUDT) access(READ)

rdef xfacilit CKR.CKRCARLA.APF  uacc(none) owner(zSecure owner) 
pe CKR.CKRCARLA.APF class(xfacilit) id(SECAUDT, SECBAUDT) access(READ)

rdef xfacilit CKR.READALL  uacc(none) owner(zSecure owner)
