Virtual Private Networks: Securing Your Business’s Network
Virtual private networks are an essential part of businesses that utilize telecommuting, as it is an ideal method for businesses that want to provide access to network resources remotely. Virtual private networks have become an industry standard for many organizations that have employees scattered across the globe. These virtual networks increase security because, as the name implies, they are private, therefore restricting access to only authorized parties.
The secure tunnel method that is deployed with these networks has built a solid foundation for remote networking that has changed even the physical infrastructure of business. Employees in remote locations have the same network access as employees that are housed within the buildings where the networks reside.
There are many ways to describe a virtual private network. You may find a great deal of information on the complexity of the process, but in the most simple terms a virtual private network is one that provides network access to remote users. This is typically accomplished through an internet source that allows users to authenticate their identity and log on to their network sources remotely.
This feature is also backed by other new advancements. Virtual private networks are growing in number, which in turn increases the need for improved security features. This is why there have been advancements in security measures. Digital signatures, for example, serve as a new measure of protection from outside intruders.
Businesses that utilize virtual private networks benefit tremendously because it cuts the costs that are associated with the alternative leased lines that are used to perform the same function. Organizations also have the ability to cut the operating costs that would be spent on long distance charges. This yields increased revenues for companies that would also acquire the costs of third party support for the servers that would be required to maintain the remote connectivity.
The ability for remote offices to connect is an essential part of the daily routine for many businesses. Many large corporations have employees that telecommute. There are also companies that have smaller branch offices that rely on the resources of the network to perform a variety of tasks. It has proven to be a powerful tool that is gaining even more use as smart phones and other portable electronic devices grow in popularity.
The concept of virtual private network supersedes the ideology that was formed in the creation of intranet networks. The intranet sites were secure, but virtual private networks take remote access to a whole new level of utility. These virtual resources allow different users to access documents and multiple drives that reside on organizational servers.
It helps increase network productivity because employees within an organization are no longer limited by geographical location. It also cuts down the time that it takes to email documents back and forth. This is ideal for employees that may be working on parts of a project together even though they are not in the same physical location.

NETWORK IP SECURITY
Though many cameras that do this are webcams the term IP camera is frequently useful only to those used for the security purpose. The initial centralized camera was introduced in 1996 by Axis communications. It was known as Axis Net eye 200 and was introduced by the group of Martin Green and Carl Axel. It used a custom web server inside to the camera. In the late 1999 the organization started using fixed Linux to operate their camera. The initial camera was introduced in 1999 by Robotics. IP cameras are accessible at decree from 0.3 to 11 mega pixels. In the customer TV trade in the early on 21st century there has been a move towards high description videos.
TYPES OF IP CAMERAS
There are basically two types of IP cameras.
• Centralized cameras they require a central network video recorder to grip the recording, alarm and video management.
• Decentralized cameras they do not require a central network video recorder as the camera has recording ability built in and can thus record directly to storage media digital.
Such as hard disk drives, flash drives, and network storage attached.
ADVANTAGES
• Two way audio through a single network. Cable allows its users to communicate with what they are watching.
• High image decree IP cameras have a decree of high megapixels and HDTV image quality at per second 30 frames.
• Flexibility IP cameras can rotate around everywhere on an IP networking.
• Distributed aptitude with IP cameras can be located in cameras they allowing in analytics solutions.
• Transmission of command of pan, tilt, zoom cameras through only one wire.
• Authentication and encryption IP cameras give safe and secure data transmission through authentication and encryption methods such as WPA, AES and WEP.
• Remote accessibility live video from selected camera can be seen from any computer.
• Cost benefit for large security systems. Research shows that for system with not more than 16 cameras analogue devices are very cheaper from 16 and 32 they are equal.
• IP cameras are able to purpose on a wireless network. First design has to be done via a router after the IP camera is installed it can be used easily.
