This KB article provides general information and outlines possible tests to help users determine whether login activity recorded by their Juniper SRX device is valid or if it is being incorrectly recognized as root login activity by a SIEM tool. The article offers insights into common scenarios and troubleshooting steps to assist users in accurately interpreting and addressing user login activity logs in their SIEM environment.

• SRX Cannot Detect Root Login Activity: Users may observe that their Juniper SRX device fails to detect or log root login activity, even when it occurs within the network.
• SIEM Tool Reports Root Login Activity: Conversely, the SIEM tool may indicate root login activity, suggesting that such logins are occurring.
• Other User Activity is Visible: Both the SRX device and the SIEM tool may consistently record and display login activity for other users on the network. However, discrepancies between root login detection persist.

These symptoms highlight a potential issue where root login activity is inconsistently recognized by the SRX device and the SIEM tool, while other user login activities are consistently captured. This inconsistency requires further investigation to determine the cause and ensure accurate monitoring of network login events.

To address the inconsistency in the recognition of root login activity between the Juniper SRX device and the SIEM tool, follow these steps:

Check SSH Root Access Configuration:

Verify whether root access is allowed through SSH on the Juniper SRX device. Ensure that the device configuration permits or restricts root logins via SSH.

Test Login with Different Users:

Perform login tests using different user accounts on your network. Ensure that these login attempts are correctly recorded by both the Juniper SRX device and the SIEM tool. This step helps establish a baseline for normal user login activity.

Test Login with Root User:

Conduct login tests using the root user account on your network. Carefully observe how these login attempts are captured by the Juniper SRX device and the SIEM tool. Pay close attention to any discrepancies or inconsistencies in the recorded activity.

Correlate Login Activity:

Analyze the login activity records from both the SRX device and the SIEM tool. Cross-reference the login events to identify any instances where a non-root user's activity is being incorrectly recognized as root user activity. This correlation process can help pinpoint the source of the issue.

By following these steps, you can diagnose and address the inconsistency in root login activity recognition, ultimately enhancing the accuracy of your network security monitoring and logging processes.
