When packet capture is used on a Cisco Secure Firewall Threat Defense (FTD) device and the packet flow is waiting on the malware query, the Snort verdict appears as 'retry.' This indicates that the device is still processing the malware analysis and has not yet determined the final action for the packet.

The 'retry' verdict signifies that the packet is in a holding state while awaiting the result of the malware inspection, which helps in maintaining the security posture until a definitive decision is made.

To configure URL filtering such that users receive a warning when they access a specific website (e.g., http://www.badadultsite.com) and have the option to continue to the site, the engineer needs to perform the following actions:

Configure an access control rule:

Create a URL object for http://www.badadultsite.com.

Set the action for this URL object to 'Interactive Block,' which prompts the user with a warning and allows them to proceed if they choose to.

Set the Interactive Block Response Page:

Navigate to the HTTP Responses tab in the access control policy editor.

Set the Interactive Block Response Page to 'System-provided' to ensure that users see the default warning page provided by Cisco Secure Firewall Management Center.

These actions ensure that only the specified website triggers an interactive block, while other websites are not blocked.

The Encrypted Visibility Engine (EVE) in Cisco Secure Firewall Management Center is enabled under the SSL tab of an access control policy. EVE provides visibility into encrypted traffic, allowing the firewall to detect threats even when traffic is encrypted.

Steps to enable EVE:

Navigate to the access control policy in FMC.

Go to the SSL tab.

Enable Encrypted Visibility Engine (EVE) to analyze encrypted traffic.

This configuration helps in identifying and mitigating threats within encrypted traffic without the need for full decryption.

To connect to a Secure Endpoint private cloud instance from Cisco Secure Firewall Management Center (FMC), the network engineer requires the SSL certificate for the Secure Endpoint private cloud instance. This SSL certificate is necessary to establish a secure, trusted connection between the FMC and the private cloud instance.

Steps:

Obtain the SSL certificate from the server administrator.

Import the SSL certificate into the FMC.

Configure the connection to the Secure Endpoint private cloud instance using the provided hostname and SSL certificate.

This ensures a secure and authenticated connection to the private cloud instance.

When performing packet capture on a Cisco Secure Firewall Threat Defense (FTD) device, ensuring that the allocated memory is sufficient is crucial for capturing all necessary traffic during a specified capture session. If users experience issues accessing a server and the engineer suspects not all traffic was collected, it indicates that the current memory allocation might not be enough to store the entire capture data for the 15-minute session.

Steps:

Check the current memory allocation for packet captures on the FTD device.

Increase the memory allocation if it is insufficient to handle the volume of traffic expected during the capture session.

This ensures that all relevant traffic is captured and can be analyzed to diagnose and resolve the network issue.

If users report that Cisco Duo 2FA fails when attempting to connect to the VPN on a Cisco Secure Firewall Threat Defense (FTD) device, and the VPN troubleshooting log in FMC shows an error indicating that the Cisco Duo AAA server has been marked as failed, the root cause is likely missing Duo trust certificates on the FTD device. Trust certificates are essential for establishing a secure and trusted connection between the FTD and the Duo authentication service.

Steps:

Obtain the necessary Duo trust certificates.

Install the certificates on the FTD device.

Verify the configuration to ensure that the FTD device can properly communicate with the Duo AAA server.

This resolves the authentication failure by ensuring that the FTD device can trust the Duo server.

To change the mode of a Cisco Secure Firewall Threat Defense (FTD) device in the Cisco Secure Firewall Management Center (FMC) inventory, the engineer must follow these steps:

Register the Secure FTD with Secure FMC.

Change the firewall mode.

Deregister the Secure FTD device from Secure FMC.

To perform these actions, accessing the Secure FTD CLI from the console port is necessary. This allows the engineer to execute the required commands to change the firewall mode and manage the registration status of the FTD device.

Steps:

Connect to the Secure FTD device via the console port.

Access the CLI and execute the command to change the firewall mode (configure firewall-mode).

Deregister the device from FMC if needed.

Register or re-register the device with FMC as required.

To block traffic to known cryptomining networks using Cisco Secure Firewall Threat Defense (FTD) managed by Cisco Secure Firewall Management Center (FMC), the network administrator needs to configure Security Intelligence in an Access Control Policy. Security Intelligence allows administrators to block traffic based on threat intelligence feeds, which include known malicious IP addresses, domains, and URLs.

Steps:

Navigate to Policies > Access Control > Access Control Policy in FMC.

Edit or create an Access Control Policy.

Go to the Security Intelligence tab.

Enable the relevant threat intelligence feeds that include cryptomining networks.

Apply the policy to the FTD device.

This configuration ensures that traffic to known cryptomining networks is blocked, enhancing the network's security posture against cryptomining threats.

In a passive IPS deployment for a Cisco Secure Firewall Threat Defense (FTD) device, the administrator must configure the interface to operate in passive mode. This involves setting the interface mode, associating it with a security zone, enabling the interface, and setting the MTU parameter.

Steps:

Set the interface mode to passive:

In FMC, navigate to Devices > Device Management.

Select the FTD device and configure the relevant interface.

Set the interface mode to 'Passive.'

Associate the interface with a security zone:

Create or select an appropriate security zone.

Assign the passive interface to this security zone.

Enable the interface:

Ensure the interface is enabled to receive traffic.

Set the MTU parameter:

Configure the Maximum Transmission Unit (MTU) parameter as required.

This ensures that the FTD device can inspect traffic passively without impacting the network flow.
