Demystifying the Catalyst: Cisco Context Aware Secure Access (Security Group Tags – SGT) Technology

In this blog, let us take a look at how Catalyst access switches enable and enforce context aware access to IT resources.

Many types of devices, including laptops, smartphones, and tablets, are used by end users to connect to the network wired, wirelessly, and remotely through VPN. With bring your own device (BYOD) access, the devices can be personal or corporate owned. Every enterprise has policies that dictate who can access what applications and databases, when and how. Traditionally, IT manages the policy either by introducing appliances at points in the campus where users connect or by manually configuring all the access switches. Appliances incur additional capital and operational expenses, whereas manual configuration of the switches requires maintenance of every switch. Moreover, the network can carry traffic using Ethernet, IPv4, IPv6, or other technologies, so the configuration must keep up with changes in technology, which leads to higher operational complexity and costs.
