![]() For example, NGFWs integrate intrusion prevention (IPS), enabling them to identify and block malicious content contained within the body of a network packet. When used as a combined firewall and router, an NGFW will inspect a packet’s headers and contents, evaluate it against its predefined rulesets, and then use the IP address included in the packet header to send the traffic out the port that will take it to its intended destination.Īn NGFW has the ability to dramatically simplify and improve an organization’s network security by integrating multiple network and security functions in a single solution. In fact, most NGFWs incorporate routing functionality, enabling them to replace a standalone router at the boundary of a private network. NGFWs are firewalls that incorporate a range of security capabilities, including both deep packet inspection and networking functions. Firewalls, on the other hand, are security appliances designed to protect a private network against external cyber threats. Routers link networks together and help to direct network traffic from its source to its intended destination. Routers and firewalls are both critical components of an organization’s network infrastructure. Firewalls come in a variety of forms, including stateless and stateful firewalls - which make decisions based solely on IP address and port in packet headers - and next-generation firewalls (NGFWs), which incorporate additional functions - such as an intrusion prevention system (IPS) - and can identify malicious content in the body of a network packet. For example, a firewall may be configured to block traffic to or from certain IP ranges, restrict inbound network connections, or prevent certain network protocols from entering or leaving the corporate network.įirewalls are important to an organization’s cybersecurity program because they can block potential inbound threats and outbound data exfiltration. The rules use the packet’s header - and potentially its contents - to determine whether or not it should be permitted to enter or leave the network. For instance organizations often have a perimeter firewall to segment internal networks and assets of an organization from the Internet.įirewalls work based on predefined firewall rules. ![]() Firewalls are deployed at the edge of the network - where it connects to another network - and all traffic flows through the firewall for inspection and filtering. ![]() A firewall is a solution that defines and protects network boundaries.
