CYB-15 · Cyber security
Orphaned accounts (former staff, former contractors) represent a persistent access risk. A formal joiners-movers-leavers (JML) process must exist to provision, modify, and revoke access to all systems within defined timeframes. Departing staff access must be revoked on the same day as departure.
Trigger
No formal JML access management process; evidence of active accounts for former employees; access not reviewed in last 6 months; no defined revocation SLA
Applicability gate
This is a readiness rule mapped to JS2 themes. Its presence in the library does not establish that JS2 applies directly to the firm.
Citation
This control maps to the public instruments below. The mapping does not establish entity applicability.
Remediation
Implement a JML access management checklist. Define revocation SLA (same-day for involuntary, 24-hour for voluntary departures). Conduct a full access audit. Implement quarterly access certification reviews.
