At a special media event hosted by Cisco at the RSA Security conference in San Francisco this week, the company unveiled a new vision for network security. Cisco is deploying new security technologies adapted to meet the needs of an increasingly diverse and mobile network.

Between the BYOD trend, and the need to allow various partners, suppliers, contractors, and others to access the network in some limited capacity, businesses need finer control over access permissions. The problem is that most of the security tools available today do not provide enough control, so many organizations are being forced into a choice between security and productivity.
