This corresponds to a different condition: A firewall's application logs show unknown users on a legacy rule and Policy Optimizer cannot recommend identity restrictions. The directly relevant correction here is: Use Policy Optimizer or hit information to review historical usage, dependencies and change windows before a controlled removal.

This corresponds to a different condition: A rule appears to allow unknown-tcp traffic from a critical factory subnet; App-ID recommendations do not identify a clear business application. The directly relevant correction here is: Use Policy Optimizer or hit information to review historical usage, dependencies and change windows before a controlled removal.

This corresponds to a different condition: An e-commerce policy continues to allow broad application any on service any despite the last quarter showing only two approved apps. The current report has a distinct control gap; Unused-rule findings require observation-window and business-impact review, not automatic deletion.

This corresponds to a different condition: An e-commerce policy continues to allow broad application any on service any despite the last quarter showing only two approved apps. The directly relevant correction here is: Use Policy Optimizer or hit information to review historical usage, dependencies and change windows before a controlled removal.

This corresponds to a different condition: A firewall's application logs show unknown users on a legacy rule and Policy Optimizer cannot recommend identity restrictions. The discriminating evidence is: Check hit history, business owner, policy dependencies and planned monitoring period.

This corresponds to a different condition: A rule appears to allow unknown-tcp traffic from a critical factory subnet; App-ID recommendations do not identify a clear business application. The discriminating evidence is: Check hit history, business owner, policy dependencies and planned monitoring period.

This corresponds to a different condition: A firewall's application logs show unknown users on a legacy rule and Policy Optimizer cannot recommend identity restrictions. Known employees appear under correct identities and the replacement rule includes reliable user conditions.

This corresponds to a different condition: An e-commerce policy continues to allow broad application any on service any despite the last quarter showing only two approved apps. The two approved apps continue on expected ports while a third test app is denied under the new rule.

The current report has a distinct control gap; Unused-rule findings require observation-window and business-impact review, not automatic deletion.

This is a controlled and useful step for the described condition, not the unsafe shortcut. Unused-rule findings require observation-window and business-impact review, not automatic deletion.

This is a controlled and useful step for the described condition, not the unsafe shortcut. The shortcut to reject is: Bulk-delete every rule with a zero counter since the last device reboot.

This is a controlled and useful step for the described condition, not the unsafe shortcut. Check hit history, business owner, policy dependencies and planned monitoring period.

Check mapping agent/connector health and unknown-user events in Log Viewer. Correct: Repair User-ID data visibility and correlate sources before using recommended source-user restrictions. Verify: Known employees appear under correct identities and the replacement rule includes reliable user conditions. This corresponds to a different condition: A firewall's application logs show unknown users on a legacy rule and Policy Optimizer cannot recommend identity restrictions. The current report has a distinct control gap; Unused-rule findings require observation-window and business-impact review, not automatic deletion. The directly relevant correction here is: Use Policy Optimizer or hit information to review historical usage, dependencies and change windows before a controlled removal. The discriminating evidence is: Check hit history, business owner, policy dependencies and planned monitoring period.

Compare 90-day App-ID observations, rule hit history and suggested service field values. Correct: Use policy optimization findings to restrict app identities and set application-default where normal service ports are observed. Verify: The two approved apps continue on expected ports while a third test app is denied under the new rule. This corresponds to a different condition: An e-commerce policy continues to allow broad application any on service any despite the last quarter showing only two approved apps. The current report has a distinct control gap; Unused-rule findings require observation-window and business-impact review, not automatic deletion. The directly relevant correction here is: Use Policy Optimizer or hit information to review historical usage, dependencies and change windows before a controlled removal. The discriminating evidence is: Check hit history, business owner, policy dependencies and planned monitoring period.

Inspect unknown-tcp source/destination pairs, traffic samples and allowed service/port scope. Correct: Investigate the unknown flow using session logs and packet/context evidence before selecting a restrictive App-ID policy. Verify: Legitimate proprietary sessions are documented and safely constrained while unexplained traffic is denied. This corresponds to a different condition: A rule appears to allow unknown-tcp traffic from a critical factory subnet; App-ID recommendations do not identify a clear business application. The current report has a distinct control gap; Unused-rule findings require observation-window and business-impact review, not automatic deletion. The directly relevant correction here is: Use Policy Optimizer or hit information to review historical usage, dependencies and change windows before a controlled removal. The discriminating evidence is: Check hit history, business owner, policy dependencies and planned monitoring period.

Convert unknown-tcp to application any to avoid maintaining a custom policy. This is the shortcut under scrutiny. In this case it fails because: Unknown application classification can reflect proprietary protocols, incomplete inspection or evasive traffic. A safe correction instead is: Investigate the unknown flow using session logs and packet/context evidence before selecting a restrictive App-ID policy. Verify using: Inspect unknown-tcp source/destination pairs, traffic samples and allowed service/port scope.

This corresponds to a different condition: A firewall's application logs show unknown users on a legacy rule and Policy Optimizer cannot recommend identity restrictions. The current report has a distinct control gap; Unknown application classification can reflect proprietary protocols, incomplete inspection or evasive traffic.
