Next-generation firewalls (NGFW)

Next-generation firewalls (NGFW) combine traditional firewall technology with additional functionality, such as encrypted traffic inspection, intrusion prevention systems, anti-virus, and more. Most notably, it includes deep packet inspection (DPI). While basic firewalls only look at packet headers, deep packet inspection examines the data within the packet itself, enabling users to more effectively identify, categorize, or stop packets with malicious data.

Proxy firewalls filter network traffic at the application level. Unlike basic firewalls, the proxy acts an intermediary between two end systems. The client must send a request to the firewall, where it is then evaluated against a set of security rules and then permitted or blocked. Most notably, proxy firewalls monitor traffic for layer 7 protocols such as HTTP and FTP, and use both stateful and deep packet inspection to detect malicious traffic.

Network address translation (NAT) firewalls allow multiple devices with independent network addresses to connect to the internet using a single IP address, keeping individual IP addresses hidden. As a result, attackers scanning a network for IP addresses can't capture specific details, providing greater security against attacks. NAT firewalls are similar to proxy firewalls in that they act as an intermediary between a group of computers and outside traffic.

Real-time Bandwidth Monitoring

Firewall Analyzer provides network administrators and MSSPs (Managed Security Service Providers) an unique way to monitor the internet traffic of the network in near real-time. Firewall traffic data is collected and analyzed to get granular details about the traffic across each firewall. There is no requirement for any probes or collection agents to get these details on the traffic.

Live Reports
The Live Reports on traffic through a firewall is displayed in the graph and table format. The Live Reports of a firewall are automatically updated to show details of incoming and outgoing traffic for each monitored firewall. The graph is available for the last 24 hours, 7 days, 30 days, and 1 year. The graph can be drilled down to find the amount of data transacted. The table displays the minimum, maximum, and average speed during the period.

How stateful inspection firewalls work

Stateful inspection firewalls -- also known as dynamic packet-filtering firewalls -- maintain a table that keeps track of all open connections. When new packets arrive, the firewall compares information in the packet header to the state table and determines whether it is part of an established connection. If it is part of an existing connection, then the packet is allowed through without further analysis. If the packet doesn't match an existing connection, it is evaluated according to the rule set for new connections.

Stateful inspection firewalls monitor communication packets over time and examine both incoming and outgoing packets. Outgoing packets that are requests for specific types of incoming packets are tracked, and only those incoming packets constituting a proper response are allowed through the firewall. Although stateful inspection firewalls are quite effective, they can be vulnerable to denial-of-service (DoS) attacks.
