Reduce complexity that is inherent in the security change process.
The modern data center is chock full of business applications comprised of complex, multi-tier architectures, numerous components, and intricate, underlying communication patterns that drive network security policies. While individual rules support various applications, an individual "communication" may be forced to travel across multiple policy enforcement points. Hundreds or even thousands of rules can be involved and can consist of multiple potential interdependencies that are configured across tens to hundreds of devices.
Along with this complexity is the challenge of keeping up with dynamic business needs — whether it’s spinning up new applications or keeping existing applications relevant for your users, change is something that organizations must both deal with and embrace. A quarter of respondents to a recent study reported that they must wait more than 11 weeks for a new application to go live. The time required by IT to deploy application updates is also slower than what the business demands; the majority of respondents (59 percent) spend more than eight hours on each application connectivity change. Streamlining and automating the change process can ensure a more agile business while also ensuring that changes are accurate and secure.
A recent survey of 240 information IT and security professionals found that many organizations plan to migrate data center applications to the cloud despite often experiencing application connectivity disruptions in the process.
Virtualizing a physical data center and moving it to a private or hybrid cloud requires careful analysis of both security and connectivity needs. The challenge is that you must perform these actions without disrupting existing services and without unplanned downtime. And with data center applications typically being composed of servers, networking and storage components and security infrastructure baked with complexity, when a new application is deployed or a connectivity update is made, it is often fraught with risk. In this slideshow, AlgoSec, a security policy management company, examines five things to consider before migrating data center applications to the cloud.
