Peer poll time controls how frequently one high-availability unit sends hello or polling messages to determine whether its peer remains responsive. Peer hold time specifies how long the appliance waits without receiving the expected peer communication before declaring that peer unavailable. Decreasing both values causes the appliances to test peer availability more frequently and wait less time before initiating failover. Interface- oriented timers are used to evaluate monitored data-interface failures and do not specifically accelerate detection of a failed failover link. Although shorter peer timers improve failover speed, excessively aggressive values can cause false failovers during congestion or high CPU utilization. Cisco explains that threat defense appliances monitor peer health through hello messages on the failover link and begin additional testing after consecutive messages are missed. Cisco Secure Firewall high-availability monitoring

Cisco Defense Orchestrator (CDO) is the tool that assists engineers in performing an audit of network projects to determine which objects are duplicated across various firewall models, including Cisco Secure Firewall Threat Defense, Cisco Secure Firewall ASA, and Meraki MX Series. CDO provides a unified management interface for managing multiple security devices and can identify duplicate objects across these devices.
Steps:
* Access Cisco Defense Orchestrator.
* Connect and synchronize all relevant firewall devices (FTD, ASA, Meraki MX).
* Use the audit and reporting features in CDO to identify and manage duplicate objects.
This helps ensure consistency and efficient management across the organization's firewall deployments.

To streamline the process of reviewing events and modifying blocking of specific files across both the firewall console and the endpoint console, the security engineer should initiate the integration between Secure FMC and Cisco Secure Endpoint (formerly AMP for Endpoints) from the Secure FMC using the AMP tab.
Steps:
* In the FMC, navigate to Devices > Device Management.
* Select the device and go to the AMP tab.
* Initiate the integration by configuring the necessary API credentials and linking the FMC to the Cisco Secure Endpoint console.
* This integration allows the security engineer to view endpoint events and apply blocking actions directly from the FMC, consolidating the management tasks.
This approach simplifies the workflow by providing a single interface to manage both network and endpoint security, reducing the time and effort required to maintain security across the organization.

To allow access to a specific banking site over HTTPS, the network administrator must use SSL decryption (also known as SSL/TLS inspection) and specify the URL. This is because HTTPS traffic is encrypted, and the firewall needs to decrypt the traffic to inspect the URL and enforce the access rule.
Steps:
* Enable SSL Decryption: Configure SSL policies to decrypt the HTTPS traffic.
* Specify the URL: Define the URL of the banking site in the access control policy, ensuring that the decrypted traffic is inspected and allowed based on the specified URL.
This method ensures that only the desired banking site is accessed over HTTPS, while other HTTPS traffic can be filtered or blocked according to the organization's security policies.
