Network Security

Network Security

A network server is often utilized by businesses to ease file sharing, Internet access, and remote management, amongst other things. Typically, the network server appliance is an inexpensive personal computer (sometimes referred to as a ”thin client”). The network appliance then accesses applications stored on a Web server. Businesses often choose network appliances known as “closed box systems” which lack many features of a fully equipped PC, but provide a complete solution including limited hardware and software needed to perform a single or specialized set of functions required by the business. These “thin clients” allow for quick installation and ease-of-use, are low maintenance, and managed through a Web browser. In this environment, network security is usually provided by a software-based solution.

Network Security appliances generally consist of a set of network management and security tools that are installed on-site. Many Network Security appliances will also provide organizations with a secure virtual private network (VPN) for remote access.

Unified Threat Management (UTM) is a category of security appliances integrating a range of security features into a single appliance that has become popular with business and enterprise.

UTM appliances combine a firewall, gateway anti-virus, and an intrusion detection system (IDS) or intrusion prevention capabilities into a single platform. A UTM is deployed to both reduce complexity and protect users from blended threats. UTM appliances also provide a way to manage multiple appliances from a single location, create and manage global security policies, provide real-time monitoring and logging, as well as a single security management interface. A UTM appliance is the next step in the evolution of the traditional firewall with VPN solutions that also incorporate many additional products and services.
