Description
When application accounts are disabled, user accessibility is affected. Accounts are utilized for identifying individual application users or for identifying the application processes themselves. In order to detect and respond to events that affect user accessibility and application processing, applications must audit account disabling actions and, as required, notify the appropriate individuals so they can investigate the event. Such a capability greatly reduces the risk that application accessibility will be negatively affected for extended periods of time and also provides logging that can be used for forensic purposes. To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements. Such integration allows the application developer to off-load those access control functions and focus on core application features and functionality.

Review the Trend Deep Security server configuration to ensure System Administrators and Information System Security Officers are notified when accounts are disabled. 1. Analyze the system using the Administration >> System Settings >> Alerts. Review the email address listed in the “Alert Event Forwarding (From The Manager).” If this email address is not present or does not belong to a distribution for system administrators and ISSOs, this is a finding. 2. Analyze the system using the Administration >> System Settings >> System Events for “User Locked Out” Event ID 603.
