Subsequent-generation firewalls (NGFWs) are integral to the way forward for zero-trust safety. Gartner defines NGFWs as “deep-packet inspection firewalls that transfer past port/protocol inspection and blocking so as to add application-level inspection, intrusion prevention, and bringing intelligence from outdoors the firewall.” Persevering with its definition, Gartner advises that “an NGFW shouldn’t be confused with a stand-alone community intrusion prevention system (IPS), which features a commodity or nonenterprise firewall, or a firewall and IPS in the identical equipment that isn’t intently built-in.” 

As famous by Forrester, “NGFWs are the cornerstone of zero belief.” In a zero-trust community, NGFWs act as segmentation gateways, “taking safety controls present in particular person level merchandise (firewalls, intrusion prevention programs, net software firewalls, content material filtering gateways, community entry controls, VPN gateways, and different encryption merchandise) and embedding them in a single answer.”

Investing closely in AI and machine studying 

NGFW distributors are doubling down on R&D investments in synthetic intelligence (AI) and machine studying (ML) to distinguish themselves and ship extra worth as a part of enterprise zero-trust safety initiatives. The main focus areas of improvement are automated risk detection and response; consumer and system conduct evaluation; superior software management; and predictive analytics to determine potential safety threats earlier than they happen. By leveraging AI and ML, NGFWs can repeatedly study and adapt to the altering risk panorama, offering a simpler zero-trust strategy to defending in opposition to cyberattacks.

“Firewall distributors retooled their portfolios to use synthetic intelligence, vendor-delivered providers, and associate service for community safety. Synthetic intelligence is beginning to ship each safety efficacy and configuration steering,” mentioned David Holmes, senior analyst in The Forrester Wave™: Enterprise Firewalls Q4 2022 report. “Palo Alto Networks‘ new policy-creation wizards use AIops to repeatedly suggest greatest practices on any change, successfully offering real-time guardrails to the consumer,” Holmes writes within the Forrester report.

How firewalls contribute to zero belief 

General, next-generation firewalls are important for enterprises pursuing zero-trust safety; they assist implement strict entry controls, phase the community and shield in opposition to cyberthreats. NGFWs contribute to zero-trust safety by offering the next: 

Superior risk safety and visibility to implement least privileged entry

NGFWs’ system firmware and, for a lot of distributors, native silicon, too, are designed to be regularly up to date with enhancements towards extra granular management over who has entry to a given useful resource, for the way lengthy, from which gadgets and utilizing which particular privileged entry credential. Updates are delivered in milliseconds and clear to directors, assuaging the necessity for IT groups to carry out patch administration.

NGFWs that may combine into zero-trust environments have automated patch updates to their firmware, which hold present their IPS, software management, automated malware evaluation, IPsec tunneling, TLS decryption, IoT safety and community visitors administration (SD-WAN). 

Offering microsegmentation to cut back the assault floor of an enterprise community

Subsequent-generation firewalls could be configured to supply microsegmentation, organizing networks into smaller, extra granular safety zones that scale back the assault floor of an enterprise’s community.

NGFWs monitor and examine visitors for threats and anomalies in actual time, then act on them primarily based on the logic and guidelines outlined throughout implementation.

This may embrace blocking malicious visitors, quarantining contaminated gadgets and alerting safety personnel to potential threats.

Integration with different zero-trust safety platforms, apps and instruments

Main NGFW suppliers generally publish open APIs designed to streamline the mixing of their programs throughout enterprise tech stacks. NGFWs are most frequently built-in with software gateways and safety data and occasion administration (SIEM) programs so safety groups can achieve a extra complete view of the community and its safety posture. This might help enterprises to detect and reply to safety threats extra successfully.

Consumer- and system identity-based controls prohibit entry to particular areas of a company community

NGFWs use entry controls which might be primarily based on the identification of the consumer or system making an attempt to entry the community.

For instance, an NGFW could be configured to permit or block entry to sure assets or areas of the community primarily based on the consumer’s function, job perform or the kind of system getting used. This helps make sure that solely approved customers and gadgets have entry to delicate assets, lowering the chance of unauthorized entry and information breaches.

System- and identity-based authentication for each useful resource request

Conventional firewalls usually depend on community location to find out belief. NGFWs built-in right into a zero-trust framework use identity-based insurance policies and multifactor authentication to confirm gadgets’ and customers’ trustworthiness. This can be a extra granular and dynamic strategy to granting entry to community assets, endpoints and gadgets. 

Microsoft Azure depends on NGFWs to ship zero belief 

Microsoft Azure makes use of next-generation firewalls (NGFWs) to supply zero-trust safety by permitting enterprises to implement strict entry controls and phase their networks into separate safety zones, enhancing the networks’ total safety posture.

With Azure Firewall, enterprises can create and implement guidelines to manage inbound and outbound visitors to and from their Azure digital networks. This consists of permitting or blocking visitors primarily based on varied standards, such because the visitors kind, the visitors’s supply and vacation spot, and the identification of the consumer or system initiating the visitors.

Through the use of Azure Firewall to phase the community into separate safety zones, enterprises can higher safe delicate areas of the community, comparable to servers or databases, and isolate them from different elements of the community that will not want entry to these assets.

Along with controlling visitors circulate, Azure Firewall could be configured to watch and examine visitors for threats and anomalies and reply appropriately. This may embrace blocking malicious visitors, quarantining contaminated gadgets and alerting safety personnel to potential threats.

Along with Azure Firewall, Microsoft Azure affords different safety options supporting zero-trust rules, comparable to Azure Non-public Hyperlink. This service permits enterprises to securely entry Azure PaaS providers and Azure-hosted APIs over a personal community connection, serving to to guard in opposition to information exfiltration and different kinds of cyberthreats.

Through the use of Azure Non-public Hyperlink and different safety options, enterprises can set up safe, personal community connections to assets in Azure, additional lowering the chance of knowledge breaches and different safety incidents.

NGFWs and 0 belief are on a collaborative path 

Search for NGFW distributors to proceed investing in AI and ML applied sciences to distinguish their platforms additional. Search for them to additionally opportunistically determine particular areas of the tech stack that they’ll actively consolidate into their product and repair methods. NGFWs will more and more be designed to fit into zero-trust community entry (ZTNA) networks and play a cooperative function in zero-trust frameworks. 

Distributors might want to additional enhance API integrations, primarily with IPS, SIEM programs and data-loss prevention (DLP) programs, to supply a extra complete strategy to safety. They’ll additionally want to focus on how software-defined networking (SDN) could be extra adaptive whereas offering extra granular management over community visitors.
