Next-generation firewalls are able to identify the applications you use and distinguish between them. Rather than allowing traffic to pass through typical Web ports, these network tools apply different policies based on your business’ rules for Internet applications, such as YouTube or your CRM, or for desktop applications like Microsoft Outlook.
How And Why Firewalls Evolved
New-age firewalls are a product of new-age threats. These attacks – of the Web-based malware, targeted, application-layer and other varieties – are creating a more threatening network landscape. The simple packet filtering capabilities of Stateful Packet Inspection (SPI) firewalls were once enough to block unwelcomed applications, as most applications met port-protocol expectations and could be blocked. Preventing user access to unsafe applications was swift and effective.
But with the advent of the aforementioned “new-age” threats, the landscape has changed. The issue has not been the network components so much as the application changes and weaknesses. Over 80 percent of all new malware and intrusion attacks exploit those application weaknesses.
Establishing protection guidelines using IP addresses, protocols and ports no longer gets the job done. Applications such as Microsoft 365 are now hosted over the Internet to accommodate new business practices and norms, such as using cloud-based services or enabling team members to work from home. But this change has made it impossible for SPI firewalls to distinguish between business and personal programs.
Obstructing an application that uses Port 80 by blocking that port would also mean obstructing applications that your team needs to do its job. In essence, you would be blocking needed programs like Microsoft 365 and those for personal use because they all use that port.
The response has been next-generation firewalls.
These network tools have better awareness of individual applications because of their deep packet inspection capabilities. They enable you and other network administrators to create detailed rules to regulate the use of any application on your network.
Connecting To Your Network
Next-generation firewall appliances need to be installed in-line, and this creates a risk of network downtime. Should the firewall fail or need maintenance, the network link has to be brought down for repair. With a bypass or network TAP, you’re able to ensure that your network continues to be operable if maintenance is required.
As a firewall technology solution brief explains, “Should the inline device lose power or need to be taken offline for scheduled maintenance, the TAP will ‘bypass’ the device and keep traffic flowing through the network. If the TAP should lose power, it will fail-safe without impacting network traffic.”
To more efficiently and effectively manage your network and safeguard it from applications that might threaten your network, a next-generation firewall is far better equipped to get the job done and maintain the productivity of your business.
