This article is to share with you about the use of windows firewall. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

The use of windows firewall can: 1, improve the security of an internal network and reduce the risk by filtering insecure services; 2, strengthen the network security strategy; 3, monitor and audit network access and access; 4, through the division of the internal network through the firewall, it can achieve the isolation of key network segments of the internal network and prevent the leakage of internal information.

Firewall technology is a technology that helps computer networks build a relatively isolated protection barrier between their internal and external networks by organically combining all kinds of software and hardware equipment used for security management and screening, in order to protect the security of user data and information.

What can I do with windows firewall?

1. Firewall is the barrier of network security.

A firewall can greatly improve the security of an internal network and reduce risk by filtering insecure services. Because only carefully selected application protocols can pass through the firewall, the network environment becomes more secure. for example, the firewall can prohibit the familiar insecure NFS protocols from entering and leaving the protected network, so that it is impossible for external attackers to use these fragile protocols to attack the internal network, and the firewall can also protect the network from routing-based attacks. Examples include source routing attacks and ICMP redirect paths in the IP option.

2. It can strengthen the network security strategy.

Through the configuration of the security scheme centered on the firewall, all the security software can be configured on the firewall. Compared with distributing the network security problems to each host, the centralized security management of the firewall is more economical.

3. Monitor and audit network access and access.

If all visits go through the firewall, the firewall can record these visits and log them, and it can also provide statistics on network usage. If suspicious actions occur, it is also very important to collect the use and misuse of a network, and network usage statistics are also very important for network demand analysis and threat analysis.

4. Prevent the leakage of internal information

Through the division of the internal network by the firewall, the isolation of the key segments of the intranet can be realized, thus limiting the impact of local key or sensitive network security problems on the global network. secondly, privacy is an issue of great concern to the internal network. an unnoticed detail in an internal network may contain clues about security and arouse the interest of external attackers. As a result, some security loopholes in the internal network have been exposed, and firewalls can be used to hide services that disclose internal details.

Thank you for reading! What is the use of the windows firewall to share here, I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it and let more people see it.
