Description
Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state. Additionally, sensitive account information must not be revealed through error messages to unauthorized personnel or their designated representatives. In the A10 Networks ADC, the audit log is maintained in a separate file separate from the system log. Access to the audit log is role-based. The audit log messages that are displayed for an admin depend upon that administrator’s role (privilege level). Administrators with Root, Read Write, or Read Only privileges who view the audit log can view all the messages, for all system partitions.
