If humans have an immune system that must be maintained to prevent disease, so does the company’s network and devices, and its immune system is called a firewall in a computer network. For those of you who have studied the term media, maybe this system also applies there, it’s just that the definition is different.
Either the firewall in the company’s computer system or the mass media, the goal is the same, namely, to keep one part of the other, to be more secure.
Understanding Firewall
Maybe you are wondering what this word means. What does this wall of fire mean? To find out, we will start from the meaning first.
It can be said that this method or device is a safety device that must be installed by those who are connected to the internet. Either a personal network or a corporate network.
The goal is to protect, whether in the form of filtering, limiting, or even denying a relationship. The relationship in question is the relationship between networks, namely private networks and external networks that are not within its scope.
In addition, the firewall aims to keep unauthorized and authorized people from accessing company data or systems. Both from outside and inside. In other words, this method is used to implement securities policies within the company.
Know the Functions and Use of Firewalls
There are several points related to the function of this system that we can use and adapt to our needs. Following are some of its functions:
Network Security Post
It is said to be a network security post because every traffic that occurs between networks, both outgoing and incoming must pass through this system. Later this method or system will filter and sort all traffic flows according to the established procedure.
Keeping Information
The existence of a firewall is expected to protect information from leaks that occur without the knowledge of the company.
User Activity Log
When your company’s computer equipment is equipped with this system, you will pass it when you enter. In a sense, when you are going to access data, then you need to go through this firewall system so that all your activities can be recorded and monitored. You can monitor it through the statistical records available in this firewall system.
Prevent Data Modification
The next function of the firewall is to prevent data modification from other parties. For example, in terms of company data, financial reports, product specifications, and others that are company secrets. Having a firewall can prevent modification from happening.
Importance of Firewall
A firewall is a security system with the ability to activate the connected service at any time so that it automatically operates when needed and unknown access occurs.
When there is an illegal connection or suspicious traffic enters a computer network device, then the problem will become more complicated because it usually spreads everywhere. To prevent this from happening, it is very important to activate protection by using a firewall in the computer network to help avoid the practice of data theft or leakage of confidential information.
