The evidence is clear – organizations are challenged just as much by internal attacks as they are by attacks coming from outside of their “network boundaries.” With the advent of distributed Internet connectivity, VPNs, wireless technology, laptops, network-connected PDAs, and extranets, enterprise networks are now ‘borderless.’
The modern workforce of internal employees, contractors and consultants telecommute and/or regularly connect to the network from home via the Internet – and not just for e-mail – but for accessing critical internal information. This increased connectivity has led to enormous employee productivity for those who depend on easy access to information resources anytime and from anywhere, but has also created a security nightmare. Consequently, organizations realize the need to enforce granular network access policy for all forms of external access as well as internally tethered endpoints.
