Network security used to be simple: you put a wall around your entire network and secured its borders. Those borders have long since disappeared.

In today’s IT landscape, threats to network security have evolved. We have targeted cyberattacks with the nature of how networks are attacked continuously changing; data breaches from both inside and outside the corporation; unintentional leaks of corporate data from social networking sites such as Twitter and Facebook; mobile device vulnerabilities especially from employees’ personal smartphones that are used to access corporate data; and cloud computing where corporations have to rely on a third-party to ensure the security of their data.
