Cisco's firewall appliances monitor network traffic and determine whether to permit specific traffic based on defined security rules (policies). Unlike pure switches or routers, firewalls can provide transport-layer and application-layer filtering. Cisco's ASA 5500-X Next Generation Firewall (NGFW) Series is designed to replace Cisco's older ASA 5500 family of firewalls, which in turn supplanted Cisco's PIX firewalls. All these products combine Cisco's proven firewall technology with increasingly sophisticated intrusion prevention system (IPS) capabilities. Advantages of the ASA 5500-X line over legacy Cisco firewalls include a 64-bit architecture and multicore CPU technology, higher firewall and VPN throughput, more flexible management options, compatibility with Cisco's powerful advanced security services, and the ability to run multiple security services simultaneously without compromising performance.
With Cisco's acquisition of Sourcefire, the extensive line of Cisco ASA 5500-X firewalls are available with Firepower Services, based on the world's most widely deployed IPS solution and featuring enhanced capabilities such as advanced malware protection, URL filtering, analytics and automation.
Versions of ASA 5500-X firewalls are available to meet the budgets and operational requirements of small and mid-size organizations ranging from branches offices to enterprises. The combination of improved performance plus new firewall services and management options offered by Cisco for the ASA 5500-X family allow IT departments to address the momentous changes in the networking landscape such as bring-your-own-device (BYOD) and cloud computing and to deal with the 100,000-plus web-based threats that appear daily.
Progent's Cisco-certified CCIE network consultants and information security specialists can help you manage and troubleshoot your ASA 5500-X firewalls, reimage your older ASA 5500-X devices to support Firepower services, migrate from older ASA 5500 or PIX firewalls to ASA 5500-X models, configure additional ASA 5500-X devices, implement and validate security policies, connect your on-premises firewalls with public cloud services, tune your firewall configuration to optimize performance, and integrate ASA 5500-X firewall with Cisco Firepower Management Center for centralized management of your security infrastructure.
Basic Firewall Security Services for Cisco's ASA 5500-X Series
First generation Cisco ASA 5500-X firewalls are capable of running Cisco's basic software-based and cloud-based security services without requiring additional hardware modules.
Standard Cisco Security Services that can be run with ASA 5500-X firewalls include:
Firepower Services for Cisco ASA
- Cisco Security Intelligence Operations (SIO) to protect against zero-day threats by providing near-real-time threat intelligence feeds to WSE, IPS, and CWS
- Application Visibility and Control (AVC) to manage individual and group access to specific components of an application and to control certain behaviors within micro-applications
- Web Security Essentials for reputation-based security policies to control access to web sites and applications
- Built-in Cisco IPS for HIPPA, PCI and NERC CIP compliant threat mitigation that combines passive OS fingerprinting with reputation and features on-box and off-box analyses
- Cisco ASA Botnet Traffic Filter (BTF) for detecting rogue activity and infected end points
- Integration with Cisco AnyConnect Mobility Client with VPN split-tunneling to allow critical business applications while excluding unauthorized personal apps
- Cisco Cloud Web Security (CWS) utilizes a worldwide network of data centers to provide web security and application visibility
- Support for native VPN clients such as Apple iOS and Android clients
Cisco ASA 5500-X firewalls can support Cisco's ASA Firepower Services to provide layered threat protection in a single appliance. Firepower support is enabled via software modules for all ASA 5500-X models except the ASA 5585-X, which requires a hardware module. Newer ASA 5500-X models ship with Firewall preinstalled and others can be reimaged with Firepower software. ASA Firepower Services include the software-based features of Cisco's Firepower 4100 Series and Firepower 9300 Series firewall appliances. These software features include:
- Multi-layered threat protection against both familiar and new threats including targeted and persistent malware attacks
- Advanced Malware Protection (AMP) based on big data technology to detect and control breaches
- A next-generation intrusion prevention system (NGIPS) that offers contextual awareness of users, infrastructure, applications, and content to help detect multi-vector threats, automate remediation, and determine the root cause of security breaches
- Granular Application Visibility and Control (AVC) with thousands of application-layer and risk-based controls that can activate custom IPS threat detection policies
Key security features of Firepower Services for Cisco ASA 5500-X Firewalls
Smaller organizations with simpler deployments of ASA 5500-X firewalls can manage and monitor the devices locally using Cisco's on-device Adaptive Security Device Manager (ASDM), which is included with all configurations. The on-box ASDM manager includes a simple web interface that allows you to configure, monitor, and troubleshoot Cisco firewall appliances and service modules.
For more complex deployments including multi-site environments you can centrally manage ASA 5500-X Firepower software and hardware modules with Firepower Management Center physical or virtual appliances. Firepower Management Center offers in-depth unified firewall management, recognition and control over thousands of applications, intrusion defense, URL filtering, and AMP. Cisco has repeatedly rebranded and continuously refined the Firepower Management Center, which was originally the Sourcefire Defense Center and has been subsequently called the Defense Center, FireSIGHT Defense Center, and FireSIGHT Management Center.
Firepower Management Center offers ASA users expanded functionality over Cisco's ASDM on-box manager. Enhanced capabilities include contextual awareness and visibility including file trajectory, network AMP with client remediation, a dashboard with dynamically updated network visualization, automated threat assessment with prioritized impact analysis and policy tuning, full-featured IPS with preprocessor tuning, AVC with custom application detectors, custom health alerting, customization templates and export capabilities for reporting, plus APIs for remediation, host input and database access. Hardware-based features such as clustering, stacking, switching, routing, VPN, and NAT are managed using ASDM and ASA CLI instead of the Firepower Management Center.
Cisco's ASA 5500-X Product Family
Cisco's ASA 5500-X family of firewalls allows organizations to choose a model that delivers appropriate and affordable functionality. All ASA 5500-X appliances are built around Cisco's popular and time-tested stateful-inspection firewall, feature Cisco's new 64-bit multicore hardware architecture, and can run Cisco's advanced security services. The main differences among the various models in the ASA 5500-X family are capacity, performance, scalability, and fault tolerance. Progent can help you evaluate and deploy the firewalls that make the most sense for your current and anticipated requirements.
