Best Practices
What seems to be all the buzz these days is the deployment of critical infrastructure or Software-as-a-Service (SaaS) applications into a cloud environment in order to provide additional security. While most businesses are looking for the benefits that this offers to them and their customers, an area of concern is the alignment of their business operations and that security meets their specific needs or requirements. Cloud Security Companies and organizations are looking for the following when it comes to the migration of their infrastructure to the cloud:
Centralized Security Cloud security is all about control. If you are able to control access requirements and resources from one online portal, the company will save on having to deploy specialized personnel to a data center. This is how services such as AWS (Amazon Web Services) are accessed and managed. The centralization of the security means that the IT Security Pro will have more time to devote to other areas of the infrastructure, like perimeter defenses or vulnerability scanning. Reduction in Costs One of the biggest reasons if not the sole reason that an organization will choose to deploy infrastructure or applications to the cloud is the cost savings they get from using the resources that are available within that environment. Whether it is the bandwidth, server resources, or just the overall cost savings from not having to pay for a capital expenditure. Businesses continue to move to the cloud in order to gain a financial benefit from the move. This can be a significant amount, so thinking about security and how it will be used within that environment should be understood before anything moves to the cloud. Reduced Administration
The reduction in costs that a company might see from moving to a more cloud centric environment is directly associated with the reduction in the administrative costs. With streamlined services and online portals to access all of the resources in the cloud infrastructure, companies may employ a fewer number of admins than they would if they had to create the environment on their own. Also, the people who do fill these admin roles are going to be crucial to the deployment and maintenance of the cloud environment after the deployment. Reliability of Services When we look at cloud services, one of the most significant aspects that we take into consideration is the reliability of the services that are offered (up-time percentage is a BIG one here). Additionally, looking at the redundancy of various services such as:
Summary While there are a lot of reasons to move to the cloud, a business should determine how they will address security and what sort of benefits they are looking for from this critical realignment of their network architecture. Whether it happens to be overall cost savings or the enhanced capabilities that the cloud offers, IT Security and how that will be addressed needs to be a part of the discussion. Understanding the security posture once the critical assets are migrated is the wrong time to try to figure out how your security posture will be effected in such a move.
