NETWORK SECURITY

A quantum of security

If you think practical quantum computers arriving within 5-10 years means you don’t need to worry about their impact on communication network security yet, you’re in for a nasty surprise. That’s according to Jane Melia, vice president of strategic business development at Canberra, Australia-headquartered quantum security system vendor QuintessenceLabs. Adopting new security technology takes at least two years, and that protection must often continue for more than five years, so ‘this deadline is actually very close indeed’, she warns.

Securing the cloud networking supernova

Cloud services have burst upon us like a supernova, simultaneously expanding and changing network traffic patterns. The light of a supernova is also a metaphor for freedom. Like clouds floating in the sky, the internet cloud frees users from old restraints. Business users and individuals can access cloud computing and applications on-demand, at any time, from anywhere, for as much as they want and as long as they want, and pay only for what they use. It also frees IT departments from maintaining a physical infrastructure and dealing with software updates and bug fixes.
