What is Network Security?
Life would be grand if we could all exchange information freely and never worry about any malicious intent, stealing or sabotaging of our information. However, we do not live in a perfect world, so we need to be concerned about the safety and security of any data we send across any network.
Since we rely more and more each day on the Internet to manage our bank accounts, our medical records, and our credit card payments, we need to protect this valuable information. This means we must turn to network security .
But what is it really?
The field of network security was conceived with the intent of designing security methods to protect our most valued assets from the continuing threat of cyber criminals.
When referring to network security, we are really referring to a three-dimensional solution; consisting of hardware, software and physical security methods used to combat any security threat. In particular, devices such as routers, IDS's and firewalls are hardware devices used within a network to add security to all its users.
Anti-virus software and VPN's are some of the software tools used to add additional protection for any network.
The most secure networks combine hardware, software and physical security methods together, offering the most protection to all users of any network. Let's have a look at a few common tools utilized to secure modern networks.
