Firewall<\/em>\u00a0\u00a0is generally known as a system that regulates communication between 2 different networks.\u00a0With the development of the times, many companies use private internet networks to protect digital data assets from unwanted attacks.\u00a0This time, Matob<\/a> will review the definition of a firewall, its functions, benefits, types, and how it works.\u00a0<\/strong>Read on until it’s finished..<\/p>\n

What is Firewall?<\/strong><\/h2>\n

Firewall is<\/a> <\/strong>a combination of hardware and software whose function is to separate computer networks into two or more to maintain data security.<\/p>\n

Today companies have access to the internet.\u00a0Of course the network at the company has a legal entity in it.\u00a0Therefore, the company’s digital devices need to be protected from hacker attacks and other bad things.<\/p>\n

By definition, a\u00a0firewall<\/i>\u00a0is a computer network security system capable of protecting against\u00a0viruses, malware, spam,<\/i>\u00a0and other types of attacks.\u00a0It can also be said that, a\u00a0firewall<\/i>\u00a0is software to prevent access that is considered illegal or unauthorized from a private network (\u00a0private network<\/i>\u00a0).<\/p>\n

Thus, the main task of the\u00a0firewall<\/i>\u00a0itself is to monitor and control all incoming or outgoing access to network connections based on predetermined security rules.<\/p>\n

However, there are still some people or\u00a0users<\/i>\u00a0who are not\u00a0aware<\/i>\u00a0of this system and tend to ignore the security system on the computer network.\u00a0In addition, the\u00a0firewall<\/i>\u00a0also has an important role in maintaining the security of traffic on the internet network that is connected to your computer device.<\/p>\n

Firewall function<\/strong><\/h2>\n

The functions of a firewall in a network are:<\/p>\n

1. Controlling and Monitoring Data Packet Flow<\/strong><\/h3>\n

The firewall function on the first computer network<\/a> is useful in controlling and monitoring the flow of data packets flowing on the network.\u00a0The firewall function also includes modification of incoming data packets and is able to hide an IP address.<\/p>\n

2. Become a Network Security Post<\/strong><\/h3>\n

Furthermore, the firewall function on a computer network is able to control data traffic when accessing a protected private network.\u00a0All traffic either coming out or entering the network must pass through the firewall in order to be checked, either by filtering, limiting or even rejecting.\u00a0The firewall itself will work according to criteria such as the IP address of the source computer, the source TCP\/UDP port, the IP address<\/a> of the destination computer, the destination TCP\/UDP port, and information coming from the header.<\/p>\n

3. Log User Activity<\/strong><\/h3>\n

When a computer user accesses data, the firewall will record it as documentation (log files).\u00a0The existence of these data records will be used to develop a computer security system.\u00a0Then, the function of the firewall is to authenticate access to the network.<\/p>\n

4. Prevent Information Leakage<\/strong><\/h3>\n

The function of a firewall on a computer network is not just to record user activity.\u00a0Firewalls are also able to prevent the leakage of valuable information.\u00a0Simply put, a firewall that will prevent users from sending valuable files that are confidential or secret to other parties without realizing it.<\/p>\n
