Cisco 300-710 - Securing Networks with Cisco Firepower (300-710 SNCF)

To create a malware and file policy on a Cisco Secure Firewall Threat Defense (FTD) device that ensures PDF, DOCX, and XLSX files are not sent to Cisco Secure Malware Analytics, the security engineer must configure local malware analysis. Local malware analysis allows the FTD to inspect and analyze files locally without sending them to the cloud-based Cisco Secure Malware Analytics.

Steps to configure local malware analysis:

In FMC, navigate toPolicies > Access Control > Malware & FilePolicies.

Create a new malware and file policy or edit an existing one.

Define rules to inspect specific file types, ensuring that PDF, DOCX, and XLSX files are handled locally.

Set the action for these file types to "Local Analysis."

Apply the policy to the relevant access control policy.

This configuration ensures that the specified file types are analyzed locally, meeting the requirement to avoid sending them to Cisco Secure Malware Analytics.

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.

To filter traffic between multiple subnets, the engineer must implement the firewall in routed mode. In routed mode, the firewall operates as a Layer 3 device, capable of routing traffic between different IP subnets. This mode is appropriate for filtering traffic between LAN, DMZ, and WAN subnets.

Steps to configure routed mode:

Access the firewall's management interface.

Configure interfaces for each subnet (LAN, DMZ, WAN) with appropriate IP addresses and network masks.

Define security zones and apply access control policies to filter traffic as required.

This ensures that the firewall can inspect and route traffic between the different subnets, providing the necessary security and control.
