All rights reserved. Cisco Firepower Threat Defense Configuration Guide for Firepower Device Manager, Version 6.6.0. The Firepower Management Center (FMC) controller provides centralized command and control for all Firepower firewalls in the same location. It makes network-based security stronger and easier to manage while also freeing resources on our ACI leaf switches. Licensing the System. This document describes the operation and configuration of the Management Interface on Firepower Threat Defense (FTD). The options consist of defining and enabling SNMP servers, specifying the Read Community string and the SNMP User Datagram Protocol port to use, and assigning the system administrator name and location if desired. Best Practices: Use Cases for Firepower Threat Defense. Cisco is … To minimize latency when FTD inspects traffic, we used FMC to create pre-filter policies. Git also automates the approval workflow, forwarding change requests from Cisco IT to our InfoSec team for approval. A Firepower Threat Defense device is normally deployed as an active firewall and IPS (intrusion prevention system) security device. Compliance with formatting rules is automatically verified every time we check in ACL code. On FTD the next hop is a L3 device (router): © 2020 Cisco and/or its affiliates.
All of the devices used in this document started with a cleared (default) configuration. Now we’re making network-based security easier to manage—and less of a burden on our Nexus switches. We overcame those problems using FTD software.
Cisco IT gained finer control over network-based application security when we started moving to application-centric infrastructure (ACI) in 2016. “Together, FTD and Git save us hundreds of hours each quarter,” Kelly says. To save time maintaining ACLs, we’re shifting to a software development approach. The Firepower chassis runs its own OS called FXOS while the FTD is installed on a module/blade. From the FTD Command Line Interface (CLI) this can be verified in the show tech-support output. When an FTD image is installed on 5506/08/16 the management interface is shown as Management1/1.
Figure 1 illustrates this deployment. A feature called FastPath looks at the outer headers (which takes less time than checking the inner headers) to see if the flow is trusted.
“Traffic between workloads in the same network security zone passes through ACI leaf switches, which enforce security policy with contracts,” says Christopher Stokes, network engineer. Scenario 1. Best Practices: Use Cases for Firepower Threat Defense, Logical Devices on the Firepower 4100/9300, Route Maps and Other Objects for Route Tuning, 3000 Series Industrial Security Appliances (ISA). In this example Ethernet1/3 is chosen as the FTD management interface: p1, This can be also seen from the Logical Devices tab:p2, On FMC the interface is shown as diagnostic: p3. This interface is configured during FTD installation (setup).
A vulnerability in the Clientless SSL VPN (WebVPN) portal of Cisco Adaptive Security Appliance (ASA) and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.
FTD and FMC on the same subnet. Firepower System Release Notes, Version 6.1.0, Reimage the Cisco ASA or Firepower Threat Defense Device, Cisco Firepower Threat Defense Configuration Guide for Firepower Device Manager, Version 6.1, Technical Support & Documentation - Cisco Systems, FTD running on ASA5508-X hardware appliance, FTD running on ASA5512-X hardware appliance, FTD running on FPR9300 hardware appliance, ASA5506-X, ASA5506W-X, ASA5506H-X, ASA5508-X, ASA5516-X, ASA5512-X, ASA5515-X, ASA5525-X, ASA5545-X, ASA5555-X, FTD Management interface architecture on ASA5500-X devices, FTD Management interface when FDM is used, FTD Management interface on FP41xx/FP9300 series, FTD/Firepower Management Center (FMC) integration scenarios. If your network is live, ensure that you understand the potential impact of any command. Used as a source for LINA-level syslogs, AAA, SNMP etc messages.
Before then, all endpoints on the same subnet could talk to each other. Monitoring the Device. Scenario 2. Later we’ll add more FTD features and functionality. It makes network-based security stronger and easier to manage while also freeing resources on our ACI leaf switches. The vulnerability is due to inefficient memory management. This interface is used in order to assign the FTD IP that is used for FTD/FMC communication. Plans under consideration include: Cisco ACI + Firepower Threat Defense simplifies application security (PDF), Cisco Firepower Next-Generation Firewalls, To read additional Cisco IT business solution case studies, visit Cisco on Cisco: Inside Cisco IT, Automatically deploying new ACLs to FTD appliances if code passes all checks, Automatically creating endpoint groups (EPGs) that need to be in the same zone, using Cisco Tetration Analytics for application dependency mapping (ADM). Later you can modify the br1 settings as follows: Select the Edit button and navigate to Interfaces, Devices > Device Management > Device > Management, select the Edit button and navigate to Interfaces. Control-plane does not go through the FTD. This document describes the operation and configuration of the Management Interface on Firepower Threat Defense (FTD). Cisco Firepower Threat Defense (FTD) is an integrative software image combining CISCO ASA and FirePOWER feature into one hardware and software inclusive system.
As from 6.1 version, an FTD that is installed on ASA5500-X appliances can be managed either by FMC (off-box management) or by Firepower Device Manager (FDM) (on-box management). Alarms for the Cisco … As it can be seen in the figure, the FMC is on the same subnet as the FTD br1 interface: In this deployment the FTD must have a route towards the FMC and vice versa. The other problem was how much time it took to manually maintain ACLs for each VLAN — some with thousands of access-list entries.”. View with Adobe Reader on a variety of devices, View in various apps on iPhone, iPad, Android, Sony Reader, or Windows Phone, View on Kindle device or Kindle app on multiple devices, Management Interface on ASA 5500-X Devices, Management Interface on FTD Firepower Hardware Appliances, Integrate FTD with FMC - Management Scenarios. There are no specific requirements for this document. On 5512/15/25/45/55-X devices this becomes Management0/0. We have a full audit trail of ACL changes thanks to Git, an open source version control system. The recommendation is to use, a data interface instead* (check the note below). This can be visualized as: From FDM UI the management interface is accessible from the Device Dashboard > System Settings > Device Management IP: FTD can be also installed on Firepower 2100, 4100 and 9300 hardware appliances.
“One problem is scale,” says Ben Kelly, network architect. The information in this document was created from the devices in a specific lab environment. This design had two shortcomings. As of May 2020, we had migrated nearly 1,000 workloads, or 100 applications, behind FTD. Firepower Threat Defense frees up data center switches. On FPR2100 this interface is shared between the chassis (FXOS) and the FTD logical appliance: This screenshot is from Firepower Chassis Manager (FCM) UI on FPR4100 where a seperate interface for FTD managment is allocated.
FTD is a unified software image that can be installed on the following platforms : The purpose of this document is to demonstrate: The Management interface on ASA5506/08/16-X and ASA5512/15/25/45/55-X devices. For the FTD module allocate a separate data interface that for the FTD management. System Monitoring. Provides remote access (e.g. Given are some of the deployment options that allows to manage FTD that runs on ASA5500-X devices from FMC.
SNMP) to ASA engine. Now, using ACI “contracts,” we can control which specific endpoints within the subnet can communicate with one another. For FTD devices, a Firepower Threat Defence Platform Settings policy must be created, and the SNMP options configured.
© 2020 Cisco and/or its affiliates. On FPR4100/9300 this interface is only for the chassis management and cannot be used/shared with the FTD software that runs inside the FP module. FTD and FMC on different subnets.
If so, the traffic is passed through without deeper inspection.
“Traffic moving between network security zones has to pass through FTD, which enforces security policy with access control policy rules, conserving critical resources on the ACI leaf switches.”. The core function of the device is to provide active protection to the network, dropping undesirable connections and threats. “Each pair of Nexus switches can support a limited number of workloads—and we couldn’t easily move workloads from overutilized switch pairs to underutilized pairs.
Here’s how it works. The Firepower Threat Defense device does not resend the packet, because it may have freed the buffers that held the first part of the packet. Each of our production data centers has one or more pairs of Cisco Nexus 7000 switches. Provides SSH and HTTPS access to the FTD box. Connect to the FTD console and run the command: The Management interface is divided into 2 logical interfaces: br1 (management0 on FPR2100/4100/9300 appliances) and diagnostic: Yes, since it is used for FTD/FMC communication, configure it.
This is not a real problem because networking protocols are designed to cope with collisions by resending packets. Approximately 20% of our DC workloads — around 1,000 of 5,000 total — require network-based security. Before, every protected application had its own VLAN on the switch pair—and each VLAN had its own access control lists (ACLs). A vulnerability in the packet processing functionality of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. We’re starting by using FTD for high-speed packet filtering.
All rights reserved. Every workload is assigned to a zone. Getting Started.
For a standard three-tier application, like supply chain, the web server is typically assigned to the Protected DMZ zone while the application and database servers are assigned to the Protected Internal zone. Output from FTD CLISH when the device is managed by FDM: FDM it uses the br1 logical interface. We use ACI virtual routing forwarding (VRF) contexts to create network security zones: Protected DMZ, Protected Internal, and Internal. Restricting SSH access is done using the CLISH CLI, On the other hand, when Access Control Policy (ACP).
