Ensure 'Active Logins' is set to 'Disabled'

MediaNivel 1Automatizadafirefox

Descripción

This policy setting allows for the user session to be cleared upon closing the browser. The recommended state for this setting is: Disabled. Rationale: Deleting browser data will delete information that may be important for a computer investigation and investigators such as Computer Forensics Analysts may not be able to retrieve pertinent information to the investigation. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Mozilla\Firefox\SanitizeOnShutdown:Sessions (REG_DWORD); compliant when it is 0. Remediation writes 0 locally; in a domain set it through the ADMX so Group Policy does not revert it.
