It includes Application Visibility and Control (AVC), optional FirePOWER next-generation IPS (NGIPS), Cisco's Advanced Malware Protection (AMP), and URL Filtering. The FirePOWER NGFW enhancement provides advanced threat protection before, during, and after Attacks.

Used to gain total visibility into everything on your network. The technology comprises physical and virtual hosts, operating systems, applications, services, protocols, users, geolocation information, content, network behaviour, network attacks, and malware recognition. All viewed within a central, unified Management Console.

The "FirePOWER" Management Appliance is the central security management console (Figure 1) and delivers the centralised point of event and policy management for your Intrusion Prevention security operations. It provides the automatic aggregation and correlation of information generated by Cisco's next-generation firewall, ASA with FirePOWER™ Services and by the next-generation Intrusion Prevention System (NGIPS). Furthermore it manages network security and operational functions, including event monitoring, analysis, incident prioritization, and reporting, so that your Business is best protected.

CISCO ASA FIREWALL IN SUMMARY

ASA Image

The traditional firewall controlled traffic passing through it using the Layer 2 and 3 routing of the packets. Next Generation firewalls enhance that routing capability by introducing "Stateful inspection" (up to Layer 7 packet inspection) functionality to the firewall.

With the Adaptive Security Appliance (ASA) Cisco brings to the market its Next Generation Firewall. ASA implements the security screening of network traffic using sophisticated algorithms to analyse and understand what Applications are using which traffic protocols, or piggy-backing upon them, to better protect infrastructures from Internet Threats and Attacks. This is a vital modern requirement, because many legitimate Business Applications and the more refined Hacks for example, today use http port 80 protocol to exchange data and information to and from the Internet; amongst others.

Cisco ASA is available in 3 model families that are the 41xx, 55xx and 93xx (carrier) series Appliances. Appliances in the series have a range in throughput performance that are 10 to 60Gbps for 41xx models; 125Mbps to 4Gbps for 55xx models; and 20Gbps to a massive 225Gbps for the 93xx Carrier models. Performance differs between each Appliance depending upon the model that's selected and the features activated, network traffic protocols, and packet size characteristics.

The NGFW firewall enhancing features include Application Visibility Control (AVC), Advanced Malware Protection (AMP) and URL Filtering. Now the FirePOWER next-gen IPS can optionally be imaged onto the Appliances to deliver very advanced threat protection before, during and after Attacks.

Cisco Application Visibility and Control (AVC) uses deep packet inspection found in Layers 3 and 7 to recognize, analyse, and control over 1000 Applications that include voice and video, email, file sharing, gaming, peer-to-peer (P2P), and cloud-based Applications. AVC combines several Cisco IOS/IOS XE components, as well as communicating with external tools, to integrate the functions of Application Recognition; Metrics Collection and Exporting; Management and Reporting Systems; and Control, i.e. prioritization and management of application bandwidth, functionality into their firewall.

Cisco Advanced Malware Protection (AMP) uses global threat intelligence, advanced sandboxing, and real-time malware blocking to prevent breaches. It continuously analyses file activity across the network, so malware can be proactively defended against. The global threat intelligence is generated and correlated by Cisco Talos experts who analyse millions of malware samples and terabytes of data per day. That intelligence is pushed to AMP image on the ASA Appliance and then files, telemetry data, and file behaviour is compared against this context-rich knowledge base to proactively defend against known and emerging threats.
