"All interfaces in an interface object must be of the same type: all inline, passive, switched, routed, or ASA FirePOWER. After you create an interface object, you cannot change the type of interfaces it contains."

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.

A custom application detector is a user-defined script that can detect web applications, clients, and application protocols based on patterns in network traffic. Custom application detectors are written in LUA, which is a lightweight and embeddable scripting language. LUA scripts can use predefined functions and variables provided by the Firepower System to access packet data and metadata, and to specify the detection criteria and the application information1.

To import a custom application detector file that was provided by a third party, you need to follow these steps1:

In the FMC web interface, navigate to Objects > Object Management > Application Detectors.

Click Import.

Browse to the location of the LUA script file and select it.

Click Upload.

Review the detector details and click Save.

The other options are incorrect because:

Perl script is not a supported format for custom application detectors. Perl is a general-purpose programming language that is not embedded in the Firepower System.

NBAR protocol is not a file type, but a feature of Cisco IOS routers that can classify and monitor network traffic based on application types. NBAR protocols are predefined and cannot be imported as custom application detectors.

Python program is not a supported format for custom application detectors. Python is a general-purpose programming language that is not embedded in the Firepower System.

If inside clients have intermittent connectivity issues and the Cisco Secure FTD is responding to all ARP requests on the inside network, it indicates that there may be an incorrect proxy ARP configuration in the NAT policy. Proxy ARP can cause the FTD to respond to ARP requests on behalf of other devices, leading to connectivity issues.

Steps to resolve:

Review the NAT policy on the FTD to identify any incorrect proxy ARP configurations.

Disable the proxy ARP setting for the relevant NAT rules that are causing the issue.

This ensures that the FTD only responds to ARP requests as needed, preventing it from interfering with normal ARP traffic on the inside network.

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.

Cisco Security Analytics and Logging (SaaS) licenses come with a default data retention period of 90 days. This retention period allows organizations to store and analyze their security event data for up to 90 days, providing sufficient time for security monitoring and forensic investigations.
