Now, in addition to the built in firewall of the system, which security is better? 5

Rising firewall is good, but it takes up a lot of space, if your antivirus software is Rising, you can also not install a firewall, try to install the patch as much as possible.

Many people think Kaspersky is easier to use, and I personally think Norton genuine is more secure, followed by Rising genuine. (Rising should be updated frequently).

Of course, the firewall is Skynet.,It's a pretty professional firewall.。

Basically, attacks can be blocked.

Kaba, NOD

However, the memory of Kaba is too large, so it is recommended to use NOD32

It is recommended that you buy a Rising antivirus

Hello! There are two aspects to the ease of use of firewalls:

It is good to meet the firewall standards, that is, different requirements require different firewalls, and the standards can be referred to:

Good value for money. Rising Firewall is the first in China. Edamame Firewall is the world's No. 1.

Suggestions for general netizens: use 360 firewall, 360 "Trojan firewall" is the world's first firewall dedicated to defending against Trojan intrusion, the application of 360 original "100 million cloud defense", from preventing Trojan intrusion to system defense and killing, from enhancing network protection to strengthening the underlying driver, combined with advanced "intelligent active defense", multi-level and all-round protection system security, 300 million 360 users are intercepted every day The peak number of Trojan intrusions exceeds 100 million times, ranking first among all kinds of security software. It has surpassed the protection capabilities of ordinary traditional antivirus software.

The system has its own firewall, and if you don't think it's enough, you can install a 360 security guard, which has both a firewall and a clean up of system garbage and web traces. Features that make your computer run faster.

Skynet is good, but these antivirus software are all based on personal hobbies, so it's good to use them easily.

Symantec's is good, and the company is using it.

You can consider using H3C's firewall, which is more cost-effective, and which one you need depends mainly on what requirements you have.

Firewalls are also security software.

A firewall is a combination of components that are set up between different networks (such as trusted intranets and untrusted public networks) or network security domains. It can monitor, restrict, and change the data flow across the firewall, and shield the information, structure, and operation of the network as much as possible from the outside, so as to achieve network security.

Logically, a firewall is a splitter, a limiter, and an analyzer that effectively monitors any activity between the intranet and the Internet, guaranteeing the security of the internal network. In general, it is divided into several types, such as packet filtering, application-level gateway, and server.

The benefits of using Firewall are as follows:

1) Protect fragile services.

By filtering out insecure services, Firewall can greatly improve network security and reduce risk to hosts in subnets. For example, Firewall can disable NIS and NFS services from passing through, and FireWall can reject both source routes and ICMP redirect packets.

2) Control access to the system.

Firewall can provide access control to the system. For example, allowing external access to some hosts while disabling access to others. For example, Firewall allows external access to specific mail servers and web servers.

3) Centralized security management.

Firewall implements centralized security management for the enterprise intranet, and the security rules defined in the firewall can run on the entire intranet system, without the need to set up security policies on each machine on the intranet. Firewall can define different authentication methods without the need to install specific authentication software on each machine. External users only need to be authenticated once to access the intranet.

4) Enhance the confidentiality of Chi Heng.

Using Firewall prevents attackers from gaining useful information about attacking network systems, such as figer and DNS.

5) Recording and statistics of network usage data and illegal use of data.

Firewall can record and count network traffic through Firewall, provide statistics about network usage, and Firewall can provide statistics to determine possible attacks and probes.

6) Policy Execution.

Firewall provides the means to develop and enforce a cybersecurity strategy. When Firewall is not set up, network security depends on the user of each host.

The role of a firewall in a network system can be summarized as follows:

1.The firewall can effectively prevent external intrusion, and its role in the network system is:

2.control the flow of information and packets in and out of the network;

3.Provide logs and audits of usage and traffic;

4.Hide the details of the internal IP address and network structure;

5.VPN functionality is available.

One comes with it and one comes from itself.
