    Data Center Applications and the Cloud: What You Need to Know-

    Remove access rules when applications are decommissioned.

    More often than not, firewall rules are left in place by organizations when an application is decommissioned because of fears that if they are removed, an outage may occur. While breaking the connectivity for a critical application has a significant impact on the business, organizations should make it a priority to quickly and accurately remove unneeded access because this creates openings that can be exploited by attackers. Additionally, organizations should leverage their firewall rules to identify network components and applications that can be removed in order to successfully eliminate the unneeded access, without impacting the business.

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.
