Information Security, sometimes shortened to Info Sec, is the practice of defending information from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction. It is a general term that can be used regardless of the form the data may take (e.g. electronic, physical). Virtual Private Networks (VPNs) offer low-cost, secure, dynamic access to private networks. Such access would otherwise only be possible by using an expensive leased line solution or by dialing directly into the Local Area Network (LAN).
