Discussion

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 or can give configuration details about the network element. Limiting access to system logs and administrative consoles to authorized personnel will help to mitigate this risk. However, user feedback and error messages should also be restricted by type and content in accordance with security best practices (e.g., ICMP messages).

Check Content

Verify the Sentry reveals error messages only to the ISSO, ISSM, and SCA. 

1. Log in to MobileIron Sentry.
2. Go to Monitoring >> Alert Configuration.
3. Verify "Send Notifications" is enabled.
4. Verify an email list containing the ISSO, ISSM, and SCA is input in the Email List.
5. Verify the "Alert Notification Management" section is set to meet organizational requirements.

If Sentry is not configured to reveal error messages only to the ISSO, ISSM, and SCA, this is a finding.
