Least-Privilege Administration and Encryption for HR Data
A Spectrum Protect environment supports 450 nodes and 35 administrators. The help desk has 12 staff who reset node passwords and check whether backups ran. Backup administrators, 8 staff, manage storage pools and schedules. The security team requires least privilege, no shared admin IDs, TLS for all client and admin traffic, and auditable changes. Today all administrators use one SYSTEM-authority ID, and client data for HR is stored unencrypted in a directory-container pool. A new DR server will receive node replication copies over the WAN. The network team can open only TCP 1500 and one additional port. The compliance officer asks whether client-side encryption can be used for HR without breaking deduplication and replication, and whether the help desk can be given authority without letting them delete backups.
1. Define the administrator roles, authority classes, and controls you would implement. Explain how to keep the help desk from deleting backups.

Create individual admin IDs and grant only the class needed. SYSTEM stays with a small break-glass group and is not used for daily work. Storage administrators get STORAGE; policy administrators get POLICY; a read-only auditor gets ANALYST. The help desk needs query and limited node updates, so I would test the smallest built-in class that allows the required password reset and session query; if OPERATOR is broader than policy allows, put the reset behind a controlled script or restricted ID rather than granting SYSTEM. Remove the shared ID, set password expiration, and review QUERY ADMIN and the activity log for authority changes. The help desk must not be able to DELETE FILESPACE, DELETE VOLHISTORY, or change copy groups; those are storage or policy functions. Segregate DR target administration from source administration and review authority quarterly.
2. Design the TLS and network-port approach for client, admin, and replication traffic given only two open ports.

TLS should be required for client and admin sessions; enable it on the server and enforce it through client option sets, then verify with QUERY OPTION and session output. TCP 1500 is the server port. The additional port is for the client acceptor if you use prompted scheduling or the web client; confirm the configured acceptor port rather than assuming. If only polling is used, the client still needs outbound 1500, and the server does not need inbound to the client. For the DR server, open only the replication path required between servers, not the whole admin subnet. Do not rely on the shared admin ID; TLS protects the channel but not authorization. Document which service uses the second port and test from each network zone.
3. Evaluate client-side encryption for HR data. Can it coexist with deduplication and node replication, and what operational risks must be documented?
Read the worked answer
Client-side encryption protects HR data before it leaves the client, but it also makes the data opaque to server-side deduplication, so the expected dedup ratio will not apply to that data and storage estimates must assume little dedup. Replication can still copy encrypted objects to the DR server, but the target cannot dedup them either, and key management becomes the recovery risk: if the key is lost, backups are unrecoverable. I would bind HR to a separate management class and, if possible, a separate pool so capacity and replication lag are visible, and document key escrow. If dedup of HR is a hard requirement, use storage-level encryption or accept that client-side encryption and dedup are mutually exclusive. Test a restore from the DR copy before signing off.
