In what network environment is the firewall specifically used?

The firewall can be used in both local area network and public network environments. Its main function is to close unnecessary ports on the computer to prevent malicious intrusions. It can also prevent files in the computer from being leaked through special ports.

There are computer firewalls, LAN firewalls, and LAN firewalls can protect a LAN environment.(Recommended learning:web front-end video tutorial)

Firewall technology helps computer networks within it by organically combining various software and hardware devices for security management and screening. A technology that builds a relatively isolated protective barrier between , and external networks to protect the security of user data and information.

The so-called "firewall" refers to a method of separating an intranet from a public access network (such as the Internet). It is actually an application based on modern communication network technology and information security technology. Security technology, isolation technology. It is increasingly used in the interconnection environment between private networks and public networks, especially when accessing the Internet network.

At present, in terms of firewall products, new products include: intelligent firewalls, distributed firewalls and systematic applications of network products, etc.

Intelligent firewall: Adding artificial intelligence recognition technology to firewall products not only improves the firewall's security prevention capabilities, but also prevents the latest attacks from the network because the firewall has a self-learning function.

Distributed firewall: a new firewall architecture. Network firewall, host firewall and management center are the components of distributed firewall. Traditional firewalls are actually firewalls that implement protection at the edge of the network, while distributed firewalls add another layer of security protection within the network. The advantages of distributed firewalls include: supporting mobile computing; supporting encryption and authentication functions, and having nothing to do with network topology.

Systematic application of network products: mainly refers to the direct integration of security products of certain manufacturers with firewalls and packaged sales. In addition, although the products of some manufacturers are independent of each other, they can communicate with each other.
