Unified Threat Management and Network Security

To build comprehensive protection against complex and blended network threats, multiple security features need to be integrated into unified security architecture, which requires in a unified threat management (UTM).

The most significant limitations of the traditional firewall are its ability to perform payload inspection and to distinguish applications. Unified Threat Management (UTM) offers a comprehensive solution to secure network traffic without performance degradation or DDoS. UTM systems integrate multiple security fucntions like firewall, intrusuion detection/prevention, anti-virus, anti malware, anti spam, webfiltering, content filtering and VPN functions.

UTM is a set of features designed to provide applications layer inspection of traffic as it traverses a network. Similar to Intrusion detection and prevention, security devices that support UTM features decode and inspect upper layer protocols to detect malicious or simply disallowed traffic.

UTM appliances have several benefits including operating multiple defences through a single administrative interface without the burden of running multiple servers.

In the current context, network security threats are real and growing. Service providers and end users are becoming painfully aware of the consequences of unsecured networks and databases.

Most enterprises deploy security devices behind legacy routers to detect and stop malicious traffic before it reaches servers and desktops. In the event of a network intrusion security threats cause unexpected service interruption and impacts quality of service.

Inevitably, mobility, QoS and security can be viewed as three different indispensable aspects of a network. As security is an end-to-end issue, it is essential that quality of service be configurable, predictable and maintainable system-wide, including the end system devices, communication subsystem and networks. Furthermore, it is also important that all end-to-end elements of distributed systems architecture work in unison to achieve the desired application-level security.
