SSL stands for Secure Sockets Layer and is the security standard technology when a web server and a web browser establish an encrypted link. SSL keeps communications private and secure and out of the hands of the unscrupulous-minded Internet thugs. VPN stands for virtual private network, which provides a secure Internet connection by providing “tunneling” technology. Between SSL and VPN, users are more than assured that their connection to the Internet and that data transfer is safe and secure.

SSL provides data encryption and is used with online ordering and payment systems. Most browsers have SSL built into it and offer more flexibility and less administrative work for the user. Coupled with VPN benefits, it takes security to the next level. To run SSL with a VPN does not require any specialized software.

SSL uses public keys that are subject to encryption which requires two different types of keys, one of which is known to the first computer, and the other is a key sent to the second computer with which it will communicate. Once the data reaches the network’s end, it is no longer encrypted. That is where the VPN server takes over and keeps the data private and secure.

An SSL VPN is compatible with most standard web browsers and does not need special software to make the program work. Wireless connections can also be used with an SSL VPN system and are ideal when connecting to a Wi-Fi hot spot or an unsecured public network.
SSL VPN systems offer a secure and flexible option for telecommuters, travelers, and contractors to connect to an internal or private network. This is a great way to put efficiency into a task and produce more work in a timelier manner.

It is essential to ensure each computer has an up-to-date antivirus program to protect the computers from worms and viruses that do nothing but play havoc with computers and sometimes even destroy the operating system, rendering the computer useless.
