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.

Dynamic Analysis submits eligible files with an Unknown or Unavailable malware-cloud disposition to Cisco Secure Malware Analytics, formerly Cisco Threat Grid. The service executes and observes the file in a controlled environment, examines its behavior, and returns a threat score and detailed analysis report. Secure Firewall Management Center can use the returned threat score and the threshold configured in the file policy to determine whether the file should be treated as malware. Spero Analysis is different because it examines structural characteristics and generates a signature primarily for executable files. It does not provide the comprehensive sandbox-based behavioral examination described in the question. Therefore, when unknown files must be submitted to Secure Malware Analytics for deeper investigation, Dynamic Analysis is the required configuration. Cisco file-policy documentation

To perform rapid threat containment with Cisco FMC, the necessary component is Cisco Identity Services Engine (ISE). ISE integrates with FMC to provide dynamic network access control and enforcement, allowing for quick isolation of compromised endpoints based on security events detected by FMC.

Steps:

Integrate FMC with ISE by configuring the necessary settings in both platforms.

Define security policies in FMC that trigger rapid threat containment actions via ISE.

When a threat is detected, FMC can instruct ISE to isolate the affected endpoint, limiting its access to the network.

This integration enables automated and efficient threat containment, reducing the response time and mitigating the impact of security incidents.
