What Is a UTM Appliance and How Does It Work

Because threats to network systems are rapidly increasing, many companies and organizations are installing multi-layer security systems that are designed to handle the many different types of threats that can compromise a network system. Some of the different layers include a firewall, antivirus program, spam killers, vulnerability scanners, and other anti-penetration programs.

With the deployment of so many different security layers, IT administrators have to invest a lot of time managing the different layers and monitoring for security threats. A UTM appliance is capable of performing the tasks of the multi-layering system through a single appliance.

What is a UTM Appliance?

UTM stands for Unified Threat Management and is a device that is used for handling all of the tasks of programs that are generally used for multi-layered network security. A UTM appliance is a piece of security hardware that is installed on a large network and contains multiple security programs all in one application. A UTM provides an easier way to detect vulnerabilities in a network system and contains configurations that provide protection against both external and internal malicious acts.

How a UTM Appliance Works

Once a UTM appliance is installed on the network, it carries out a lot of the capabilities of the common programs that are deployed in a multi-layered network security system. Additionally, a UTM appliance contains its own vulnerability scanner which eliminates the need for a separate vulnerability scanning system.

  • Spam and Web Content Filtering: Many organizations deploy two separate programs for filtering spam and monitoring Web content to prevent network penetration by Trojans, worms, and viruses that enter the system through Web pages and email. With a UTM appliance, all of these concerns are covered with the use of a single device.
  • Traffic Control: A UTM appliance can control the traffic that is coming in and out of the network. It also helps to control browsing activities on the Web by providing site filtering services and restricts the amount of streaming media that can be downloaded onto the network which can significantly affect the performance of the network.

A lot of companies and organizations install a UTM appliance to cut back on costs of network security maintenance. When you deploy a multi-layered security system, you also have the expense of upgrades to all of the devices in the layers and the security software. With a UTM system, the maintenance and upgrades are cheaper due to the fact that it is an all-in-one appliance. Additionally, it is easier to solve technical problems and configuration issues without having to interrupt service on the network to perform these tasks.

A computer crash can occur at anytime and on any computer.

By backing up your files--personal documents, financial records, and digital pictures--you can ensure that you will never loose your precious and irreplaceable information.

There are many ways one can back up a computer: special equipment or online programs, which are becoming increasingly popular, can help you to create a sort of 'insurance policy' for the protection of all of your computer-based data.
