An administrator receives reports that users cannot access a cloud-hosted web server. The access control policy was recently updated with several new policy additions and URL filtering. What must be…

Downloading a PCAP provides raw packet data but does not immediately indicate which policy rule caused a block, and using FlexConfig to override policies can be complex and risky without clear understanding of the blocking mechanism.

Cisco Secure Firewall Management Center's connection events provide detailed logs for traffic processing, including which access control rule blocked traffic and why, which is crucial for identifying the precise root cause of the access issue. Once the specific blocking rule or reason is identified, the administrator can then precisely modify the access control policy to permit the necessary traffic to the web server without broadly opening up the network and compromising security.

Creating a new access control policy rule without first understanding the existing block may lead to conflicts, bypass necessary security controls, or fail to resolve the issue if a different rule takes precedence.

Verifying blocks with a packet capture is a troubleshooting step, but creating a rule with the 'monitor' action would only log traffic, not permit it, therefore failing to restore access to the web server.
