Cisco 300-710 - Securing Networks with Cisco Firewalls

To ensure high availability of internet access when deploying a pair of Cisco Secure Firewall Threat Defense (FTD) devices managed by Cisco Secure Firewall Management Center (FMC), the following features must be deployed:

Route Tracking:This feature monitors the reachability of a specified target (such as an external IP address) through the configured routes. If the route to the target is lost, the FTD can dynamically adjust the routing to use an alternate path, ensuring continuous internet access.

SLA Monitor:Service Level Agreement (SLA) monitoring works alongside route tracking to continuously verify the status and performance of the internet links. If the SLA for one of the ISP links fails (indicating the link is down or underperforming), the FTD can switch traffic to the secondary ISP link.

Steps to configure:

In FMC, navigate toDevices > Device Management.

Select the FTD device and configure route tracking to monitor the ISP links.

Configure SLA monitors to continuously check the health and performance of the internet circuits.

These configurations ensure that internet access remains available to users even if one of the ISPs goes down.

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.

In Cisco Secure Firewall Management Center (FMC), when two users attempt to modify a VPN policy simultaneously, the system implements a locking mechanism to prevent conflicts. The first user who selects edit on the policy locks the configuration, preventing other users from making changes until the lock is released.

Steps:

When the first user selects edit on the VPN policy, FMC locks the policy for editing.

The lock ensures that only the first user can make changes.

Once the first user saves or cancels their changes, the lock is released.

Other users can then edit the policy.

This locking mechanism ensures that configuration conflicts are avoided and only one set of changes is applied at a time.

Encrypted Visibility Engine provides visibility into encrypted TLS sessions by fingerprinting characteristics of the TLS handshake and associating them with known client applications or processes. The SSL/TLS policy supplies the encrypted-traffic handling framework used with the access control policy. Application detection must also be enabled so that the system can identify and classify applications represented by EVE fingerprints. Cisco Success Network is a telemetry and product-support capability and is unrelated to encrypted-session classification. Identity policy configuration maps users to network activity but is not an EVE prerequisite. Although current Vulnerability Database content provides fingerprinting intelligence, merely scheduling VDB updates does not complete the policy configuration described in the question. Therefore, configuring the SSL/TLS policy and enabling application detectors are the required actions. Cisco Encrypted Visibility Engine documentation

================

Reason: the command " capture-traffic " is used for SNORT Engine Captures. To capture a LINA Engine Capture, you use the " capture " command. Since the Lina Engine represents the actual physical interface of the device, " capture " is the only reasonable choice Reference:https://www.cisco.com/c/en/us/support/docs/security/firepower-ngfw/212474-working-with-firepower-threat-defense-f.html#anc10

The command is

firepower# capture DMZ interface dmz trace detail match ip host 192.168.76.14 host 192.168.76.100

firepower# capture INSIDE interface inside trace detail match ip host 192.168.76.14 host 192.168.75.14
