If there’s one topic that is never far from a CTO’s mind, it is security. After all, it is never a job that can be considered complete, given the fluid nature of risk. It is not only changing threats that have made the security landscape change in recent years, but also a massive shift towards cloud models.
This shift is generally positive. Most businesses now are taking advantage of opportunities to gain flexibility, cut capital expenditure, and access enterprise-level infrastructure without the hassle of managing it.
The benefits are great, but new security risks are apparent. As we always maintain, security must be a key consideration of any technology change or progression, and this is still the case. For some businesses, the potential security hazards of cloud have inhibited adoption, but this does not have to be the case.
So, to borrow a phrase from The Sound of Music, how do you catch a cloud and pin it down? The simple answer is, you don’t. Nobody wants to hold back the benefits of cloud, so instead it is necessary to adapt and rethink security to keep your environment safe in a new era.
If we’re going to create a secure environment in the cloud, we must consider the technology that underpins it. In a virtualised environment, traditional network-based firewalls and intrusion detection are limited to the physical network. We need to consider solutions that are designed to give IT professionals visibility of traffic between virtualised machines.
Juniper, whose Cloud Security white paper addresses the issue in depth, says that adding hypervisor-based security is the only way that organisations can get full benefit from the scalability offered by the cloud, while still allowing for the necessary segmentation of users. Their advice is worth taking time to read.
The right security architecture integrates protection of virtualised and physical workloads, making it a lot simpler to administer. The big advantage is the gains in visibility of the entire cloud-based and physical environment from a single point. IT security specialists don’t have to divide their attention between multiple systems, which gives them the opportunity for greater focus.
It stands to reason that when expertise is not spread too thinly, there is a greater possibility of noticing problems before they become crises. True cloud security options go beyond mere visibility, with an intelligence that helps anticipate potential threats before they even emerge. While in a constantly changing digital world there are no absolutes, it is possible to present a far smaller target than ever.
