NGFW vs. Traditional Firewalls

 



Traditional firewalls and NGFWs are both designed to detect and block malicious or unwanted traffic that crosses network boundaries. However, this occurs at different levels of the TCP/IP network protocol stack.

Traditional firewalls operate primarily at the TCP and IP layers of the protocol stack. They restrict the types of traffic that can enter or leave their protected network by checking the IP addresses and port numbers of inbound and outbound packets. However, their inability to see the contents of network packets leaves them blind to many modern threats.

NGFWs, on the other hand, operate at the application layer of the protocol stack. Their understanding of application traffic and ability to decrypt encrypted traffic streams allows them to identify and control application traffic and also block a wider range of threats. And unlike traditional firewall policies based on IP and service ports,

NGFWs integrate user and machine identity into security policies, which better captures business intent and provides better insight into traffic patterns within an organization.

NGFW Capabilities

As the foundation of an enterprise network security strategy, the ngfw is responsible for protecting the enterprise network from incoming threats and enforcing network segmentation, which is the cornerstone of an effective Zero Trust security strategy.

    All traffic passing through an ngfw is inspected by that firewall. This inspection allows the firewall to apply security policy rules which permit or block traffic.

20 IOT Devices connecting the world

Image
  What are IoT devices? IoT devices are non-standard computing devices that connect wirelessly to the Internet or a local area network , TechTarget reports. Internally controlled devices may transmit and receive data from other devices. Some everyday examples might be a car, a doorbell or even a refrigerator. These IoT devices can be hardware, sensors, devices, machines or devices that communicate with the network or the Internet through their applications and programs, such as the dictionary from the company that manufactures Arm . These smart devices turn ordinary objects into information-capable devices, says Cert NZ magazine.   How do IoT devices work? Many IoT devices collect information from their sensors, then use analytics software to make decisions based on that data. These devices often connect to a central server to access other information, according to Cert NZ. They compare and transfer data to websites and social services to collect data, and connect ...

Advantages of GPON

Image
  Factors such as the rise in bandwidth-intensive applications, smart cities, the proliferation of IoT, the widespread adoption of 5G, and GPON for mobile backhaul have made GPON and upcoming upgrades such as NG-PON2 the optical network of choice. Gigabit passive optical networks are becoming more popular due to their many advantages, including: • Energy efficient: As a passive system, GPON consumes very little power to operate. It is also 95% more energy efficient than copper networks. • Cost-effective: As a direct result of the previous point, GPON requires very little energy to function, which reduces operational costs. It also does not require much IT support. This is another area where costs can be significantly reduced. Because GPON is a fiber optic system that can connect directly to multiple customers using splitter technology, it requires less equipment, making it a very efficient and cost-effective solution. • High speed: Since speed is a key requirement for mo...
