The amount of URI text that is stored in Cisco WSA log files is controlled by the log-entry size parameter, which can be configured using the advancedproxyconfig command. The log-entry size parameter specifies the maximum number of bytes of the URI that will be logged for each request. The default value is 1024 bytes, but it can be changed to any value between 1 and 4096 bytes. If the URI is longer than the log-entry size, it will be truncated and a plus sign (+) will be appended to indicate that the URI was cut off. Configuring a small log-entry size can reduce the disk space and bandwidth consumption of the log files, but it can also limit the visibility and analysis of the requests.

the first three access control rules in the policy—Monitor, Trust, and Block—cannot inspect matching traffic. Monitor rules track and log but do not inspect network traffic, so the system continues to match traffic against additional rules to determine whether to permit or deny it

Explanation

With Cisco pxGrid (Platform Exchange Grid), your multiple security products can now share data and work together. This open, scalable, and IETF standards-driven platform helps you automate security to get answers and contain threats faster.

 Dynamic ARP Inspection (DAI) is a security feature that protects ARP (Address Resolution Protocol) from an attack like ARP poisoning. ARP poisoning is a technique where an attacker sends forged ARP responses to trick hosts into associating IP addresses with the attacker’s MAC address. This allows the attacker to intercept, modify, or drop traffic between the victims, creating a “man-in-the-middle” scenario. DAI can prevent this attack by validating ARP packets on untrusted interfaces, using information from the DHCP snooping database and/or an ARP access-list. If the ARP packet contains invalid MAC address to IP address bindings, it will be dropped and logged. DAI can also rate-limit ARP packets to mitigate ARP flooding attacks. DAI is configured on a per-VLAN basis and requires DHCP snooping to be enabled on the same VLANs. References :=
