por ¿Do you know what a firewall UTM And what is it used for in cybersecurity?
A firewall It can be represented, metaphorically, as the policeman who protects a network. That is to say, It is a device that serves to filter traffic entering and leaving a computer. For this, a firewall It allows us to monitor, block or admit all requests that come from a device and the responses that servers send to it.
However, it should be noted that there are different types of firewalls, which use different methods to protect networks. In this post, we will talk about one of the most commonly used types and that, in cybersecurity, it is essential to know. Next, we will explain what is a firewall UTM and why they are so widely used today to protect computer systems from threats.
What is a UTM firewall?
A firewall o UTM (Unified Threat Management) firewall It is, as the name suggests, unified threat management. That is to say, is a set of computer tools and protocols that serve to keep the perimeter network safe. Among these tools are, for example:
Virtual private network (VPN) managers– serve to maintain a secure connection with the servers used for these services.
IDS and IPS: Intrusion Detection Systems (IDS) and Intrusion Protection Systems (IPS) are software automated based on system behavior rules, which serve to detect and eliminate threats in real time. These programs, especially IPS, allow us to recognize and block cyberattacks effectively, once the rules of behavior related to them are known.
Network monitoring: is the typical function of the firewall, which is responsible for monitoring traffic entering and leaving the device. Thanks to this monitoring, cyber threats can be avoided such as:
Spyware.
Malware Trojans. Man-in-the-middle attacks man in the middle. Brute force attacks. Connections to botnets.
Why use a firewall?
We have already seen what a firewall UTM and now we will talk about What is the importance of using tools like this.
The defense of a computer system is a task that is divided into several complex functions. This happens because each system is made up of thousands of elements that could fail. Defense teams, also known as Blue Teams, must take care of each and every one of the elements that make up the system, no matter what they are.. Attackers, on the other hand, have the advantage that they only need a small security breach to cause a critical threat..
Therefore, the Blue Team must apply special security measures for each of the elements of the system. One of them, which is of high importance for companies, is the network. Networks are made up of a series of devices that connect to it and, like all parts of a system, have vulnerabilities..
There are different measures to maintain a secure network, such as strengthening the authentication processes of users who access it. In addition, It is necessary to take care of and monitor the traffic, that is, the connections established with other servers and the requests they exchange..
For this, the firewalls and UTM (United Threat Management) types are quite complete alternatives to comply with this management.. Since systems are complex and have many more elements, a firewall alone is not sufficient security to protect a network. However, it is essential to have one.
