Virtual Private Networks - Links

VPN Benefits.   Virtual private networks are commonly used by businesses that have offices in several cities, and would like to ensure that information passed from office to office over the public internet links can not be intercepted and viewed by third parties. Hence it is as if the company is operating a secure intranet.

VPN Security Features.   Properly installed VPNs use cryptographic tunneling protocols to provide the necessary confidentiality (preventing snooping), sender authentication (preventing identity spoofing), and message integrity.
