Back in the old days (before cloud computing) most companies built firewalls around their networks to protect themselves from outside intruders and data breaches. This was the most common approach to network security and was one of the best lines of defense.

Ah, the good old days! We’ve all seen the tremendous evolution of the cloud from software-as-a-service (SaaS) to low-cost, outsourced IT Infrastructure-as-a-Service (IaaS) to what is now widely referred to as enterprise cloud computing.

Now that cloud computing has become a mainstream practice and companies are implementing hybrid and multi-cloud solutions, they have to up the ante on their security practices. This includes a departure in the traditional way they’ve approached security. They can no longer just build a wall around their network. They have to protect their infrastructure from a variety of access points.

A great example of how this can be done is the recent partnership between Australia’s incumbent telecommunications provider Telstra, and data center security company vArmor. As Telstra moves to the cloud, it is building up its security arsenal to protect its virtualized and cloud assets.

“This is really important to our strategy, really important to Telstra in terms of us adding value as a cloud provider, and adding value as a multi-cloud and hybrid cloud provider. Not just providing cloud services, but the network and the security layers are really fundamentally important to us.”

As cloud computing has evolved, so has cloud security. It is still a top priority for the IT department, especially in highly regulated industries that have been the target of some very high profile security breaches.  And, as the mobile workforce expands, more employees are accessing data from multiple locations, making the challenge even greater.

As VMware CTO Chris Wolf states in this Virtualization Review article: “….it ultimately is the job of IT to protect, secure and ensure availability of applications and content residing in datacenters we don’t own, traversing networks we don’t own, and accessed by devices we don’t own. This is the new world in which IT operates.”

So how can IT managers ensure that the highest cloud security standards are in place while still focusing on all of the other network and infrastructure priorities?

The answer lies among a new generation cloud automation technologies and tools. These solutions can help companies secure their data by simplifying the management of hybrid clouds and automating processes that make compliance and policy enforcement easy.

They can alert IT managers when changes occur across their diverse cloud infrastructure; understand key interdependencies and potential impact radius; and automatically take action solving issues as they occur and closing vulnerabilities.

So, while IT managers can’t go back to the good old days when managing network security was not as complex, they can rest assured that all of their public and private clouds are being monitored 24/7 and that they will be the first to know if anything is amiss.
