Title

If the HYCU virtual appliance uses role-based access control, it must enforce organization-defined role-based access control policies over defined subjects and objects. (Cat II impact)

Discussion

Organizations can create specific roles based on job functions and the authorizations (i.e., privileges) to perform needed operations on organizational information systems associated with the organization-defined roles. When administrators are assigned to the organizational roles, they inherit the authorizations or privileges defined for those roles. Role-Based Access Control (RBAC) simplifies privilege administration for organizations because privileges are not assigned directly to every administrator (which can be a significant number of individuals for mid- to large-size organizations) but are instead acquired through role assignments. RBAC can be implemented either as a mandatory or discretionary form of access control. The RBAC policies and the subjects and objects are defined uniquely for each network device, so they cannot be specified in the requirement.

Check Content

HYCU offers the capability to leverage RBAC controls within the Web UI's Self-Service menu. The organization would need to generate and document its own specific requirements around using RBAC in HYCU. For the HYCU VM console, administrators should only allow access to anyone else deemed to be qualified as a server administrator for the system. Review the groups and accounts within Web UI's Self-Service menu. If any RBAC setting does not meet the organization's guidelines, this is a finding.

Fix Text

Ensure the correct RBAC controls and access are applied properly within the HYCU Web UI's Self-Service menu. Avoid granting too much access to any particular user or group. For the HYCU VM console, administrators should only allow access to anyone else deemed to be qualified as a server administrator for the system. To check for any unauthorized users, run the following command within the HYCU Web console: cat /etc/passwd Use the "userdel" command to remove any unauthorized users.
