A sequence in the Administrator Audit Log shows several failed sign-ins from an unfamiliar location,...

Option D combines two high-confidence indicators: unexpected successful access to a privileged identity and an immediate increase in that identity’s permissions. Zscaler records administrator login and configuration activity in audit data; its 2024 Audit Logs update states that the portal records the login name and IP address of administrators who sign in and add or modify configurations. Zscaler also supports restricting administrator access by source IP through Administrator Management settings. The temporal link between an untrusted source and role elevation therefore warrants containment, credential or session revocation, and investigation. The other choices contain either expected administrative maintenance, nonprivileged lockouts, or documented token and password events. They may merit review, but they do not demonstrate the same direct path from suspicious access to privilege escalation.
