To integrate a third-party security intelligence feed with Cisco Secure Firewall Management Center (FMC) using Threat Intelligence Director (TID), the following actions are necessary:

Upgrade to version 6.6:The FMC must be running at least version 6.6 to support Threat Intelligence Director. Version 6.2.3 does not support the necessary features for this integration.

Add the URL of the TAXII server:Threat Intelligence Director uses TAXII (Trusted Automated eXchange of Indicator Information) to pull threat intelligence data from third-party sources. The URL of the TAXII server must be added to the TID configuration in FMC.

Steps:

Upgrade FMC to version 6.6 or later.

In FMC, navigate toIntegration > Threat Intelligence Director.

Add a new TAXII server by entering the URL of the TAXII server.

These actions enable the integration of third-party threat intelligence feeds, enhancing the security capabilities of the FMC.

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.

“You cannot send backups to one remote system and reports to another, but you can choose to send either to a remote system and store the other on the Firepower Management Center.”

A file policy defines the actions that the Cisco Firepower Threat Defense (FTD) device should take when it encounters different types of files. The file policy is applied as part of an access control policy. If an access control policy does not include a file policy, the FTD device will not take any action on the files it encounters, resulting in a disposition of " unknown " for all file types except exe.
