Features for Next-Generation Firewalls

Next-Generation Firewalls (NGFW) and Firewalls as a Service (FWaaS)

Next-generation firewalls is a network security system – hardware or software – capable of detecting and blocking sophisticated attacks by applying security rules at the application and communication port or protocol levels.

A Next-generation firewalls trust the capabilities of traditional firewalls – packet filtering, address translation (NAT), URL blocking, and VPN – with quality of service (QoS) management features and features typically absent from firewalls. Includes intrusion prevention, And also SSL and SSH inspection. Deep packet inspection (DPI). Reputation-based malware detection. And application awareness. In addition, application-specific features are design to protect against many attacks targeting layers 4 through 7 of the OSI model.

The type of firewall a company needs depends on its infrastructure. If all network infrastructure and applications are on-premises, a hardware NGFW may suffice. But most modern organizations run some workloads in the cloud. Which makes FWaaS necessary (ideally, an FWaaS solution with next-gen capabilities).

What Does A Next Generation Firewalls Do?

What Does A Next Generation Firewalls Do?

A firewall is a security product that monitors and controls the network traffic based on security rules. Firewalls can be software applications installed on a server or computer or physical hardware devices that connect to an internal network. Firewalls usually sit between a trust network and an untrust network. Often the trusted network is a company’s internal network. And the untrusted network is the Internet.

What is a Next Generation Firewalls (NGFW)?

NGFWs take traditional firewalls’ capabilities. But they also consume additional features to meet a wider variety of organizational needs and block more potential threats. They call it “next generation” to differentiate them from older firewalls that do not have these capabilities.

NGFW Technologies Include:

  • Intrusion Prevention System (IPS): Analyzes network traffic. Identifies malware and blocks it.
  • Deep Packet Inspection (DPI): Improves packet filtering by analyzing each packet’s body and the header.
  • And also Application awareness and control: Identifies and blocks traffic based on its destine applications.
  • Threat Intelligence Feeds: Integrates up-to-date threat intelligence feeds to identify the latest threats

What Is Firewalls-As-A-Service (Fwaas) of Next Generation Firewalls?

A Firewall-as-a-Service (FWaaS) is a firewall hosted in the cloud by a third-party provider. “Cloud firewall” is another term for this type of service.

An FWaaS is not a physical device. And also  it is not host on an organization’s premises. Like other “as-a-Service” categories, SaaS (Software as a Service). FWaaS runs in the cloud and is accessible over the Internet.

Before the coming of cloud computing. A firewall stood between a secure network. And also an insecure network. There was a clear boundary (called a “network perimeter”) between secure and insecure networks. But in cloud computing. And also this boundary does not exist because access to trust cloud resources is over an untrust network (the Internet). Cloud-host firewalls protect these assets despite this lack of a network perimeter. The firewall vendor is configure, maintain, and update by cloud-hosted firewalls, not the customer.

What Is Cloudflare Magic Firewall of Generation Firewalls?

Cloudflare Magic Firewall is a cloud-based firewall with next-generation capabilities host on Cloudflare’s global network. And also It protects data centers, remote users, branch offices. And cloud infrastructure.

Techopedia Clarifies Next Generation Firewalls

Standard features found in traditional firewalls such as stateful inspection. Virtual private network. And packet filtering are also found in next-generation firewalls. However, next-generation firewalls are better able to detect application-specific attacks than standard firewalls. And also can thus prevent more malicious intrusions. They perform full packet inspection by checking packet signatures and payload for anomalies or malware.

Next-generation firewalls also have better application awareness and deploy various techniques to identify different applications, And also Including web-based ones. In addition. They store details of trust apps and examine data packets for any issues. And also They also keep a baseline for deviations from normal application behavior. Which can help system administrators.

Next Generation Firewalls Should Provide The Following:

  • All traditional firewall capabilities
  • Identification of unwanted encrypt applications using SSL decryption
  • And also Granular control and application awareness
  • Continuous service concerning the line bump in the wiring pattern
  • Built-in network intrusion prevention techniques
  • And also Ability to use intelligence to improve blocking decisions
  • An integrated signature-based intrusion prevention engine

Conclusion

Next Generation Firewall FWaaS can have next-generation capabilities. And an NGFW can host in the cloud. Next-generation firewalls trust the capabilities of traditional firewalls – packet filtering. Address translation (NAT). URL blocking. And also VPN – with quality of service (QoS) management features and features typically absent from firewalls.
