Today's dynamic computing environments require a more flexible and adaptive approach to security; here's how to get there.
It's no secret that information security has failed to keep up with the speed of business and IT. While data centers have become increasingly dynamic, accommodating rapid application changes and on-the-fly deployments that span private and public clouds, security has remained relatively static, based on perimeter appliances like firewalls or other network chokepoint devices that leave the insides of the data center vulnerable to attack.
In addition, security policies are tied to network parameters like IP addresses, ports, subnets, and zones. As a result, security is highly manual, potentially error-prone, lacking visibility inside the perimeter, and inflexible to changes like cloud migrations or application and environment changes. Enterprises should consider the following strategies to make their security more adaptive to the demands of rapidly changing computing environments:
