An introduction to unified threat management

Corporate networks are more vulnerable and susceptible to external threats due to virus attacks, network intrusion, spam, worms, etc.. Various network security technologies has been introduced to protect, to get enterprise resources in recent years on the network from these attacks.

Separate modules for protecting the network against viruses and worms were designed, phishing, and pharming are too disabled to activate the credentials of the user. Then came the firewalls, which secured the ports from unauthorized access while in the network work, by identifying the ports, which should leave outsiders and that should not be. All of these technologies worked well until the infrastructure complexity was not too high. The size of the networks has grown, was separately, difficult maintenance of these technologies. It was desired to have a consolidated technology, which could provide the needs and requirements in terms of network security. Therefore introduced the concept of unified threat management, or UTM.

A UTM offers related to network security, the effective and efficient security system on a corporate network offers the following solutions:

FirewallsWeb/URL FilteringAnti SpamAnti VirusNetwork intrusion/spyware ProtectionVPN or virtual private network

and may be a different type of service related to the company.

UTM adds the advantage of multiple appliances to centrally manage and flexible grouping to create policies for the same from a central management console can. It is a preventive as well as reactive protection system offers protection for various infrastructure elements, including business applications and services.

Generally three types of UTM systems it based on the area of the operation and its macroscopic very:

Hardware, special devices with ASIC chip sets are configured, the multiple threats can monitor at the same time.Fixing UTM, that on standard PC server with a specific configuration are hosted. It requires separate software-based security systems, as network operating system security, firewalls etc. on the same server are installed and configured for the backup of the number of users and applications based on the configuration.UTM distributed, the own hardware software requires security linked monitors, each with its own functionality. Even if these devices have a common control separately working interface is it which makes this customized system as a single module.

UTM systems offers a complete solution for companies that facilitates workforce configure it and maintain the entire network architecture different threats and problems.
