Enterprise IT infrastructures today have been developing rapidly over recent years and becoming increasingly complex. Cloud computing, the Internet of Things (IoT), mobile internet access and more have vastly increased the applications and endpoints run on typical organisational infrastructures – and the speed at which they can be provisioned.  In this article, we explore three of the key challenges facing IT security teams today amidst this landscape of complexity – and how they can best turn that complexity into clarity.

Challenge 1: decreased visibility

IT security begins with an understanding of what you are trying to protect. Which servers, databases, applications and devices exist within your IT infrastructure? How are they connected to each other? How is your data flowing and residing?

Challenge 2: increased endpoints

The Internet of Things (IoT) is, quite rightly, one of the hottest enterprise IT concepts of the moment. Deploy IoT devices throughout your organisation and you can gather previously untapped data, generate new business intelligence and ultimately drive powerful efficiencies and even the development of new products and services.

Challenge 3: rapidly evolving threats

Looking beyond each business’s own IT infrastructure, it is important to consider the broader cyber threat landscape which organisations need to protect themselves against. Unfortunately, like enterprise IT itself, this is a world which has developed dramatically in sophistication in recent years – and it is still evolving.

The answer: A multi-layered approach

When new IoT devices are being provisioned daily, when mobile devices are being taken off-premise and used to access the corporate system from remote locations, when public and private cloud environments are being used to deploy key business applications – the overall picture is multifaceted and multi-layered. This means, then, that a multi-layered approach to security is the only option.

What does this look like in practice? First, security needs to work at the network, the individual device and the application layer in order to provide comprehensive protection.

Second, enterprise security needs to draw on intelligence from a wide range of technical sources – as well as first-hand human experience.

Third, enterprise security needs to work on both a proactive and a reactive basis.

The role of managed services

Perhaps this sounds no less dynamic and complex than the enterprise IT landscape we laid out at the start? This is why for many organisations, a managed services approach to IT security is the ideal solution. This enables you to focus on running your business, and be assured security is in safe hands.
