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.
