Essential guide to securing hybrid IT infrastructure

Tackling security challenges when moving to a hybrid cloud architecture


Security is a constant for any IT architecture, but when moving to a hybrid IT infrastructure, new challenges open up from extending on-premise systems into the public cloud. The greater the potential attack surface, the higher the risk. In this essential guide, we examine the key security considerations for infrastructure, networks, data and hybrid cloud.

Focus: Network security

During the course of 2016 we saw the clamour around network security – which was already very loud – reach fever pitch. From allegations of nation state-level interference in crucial elections, to massive botnet attacks that brought down critical online services for millions, network security dominated mainstream news cycles for weeks on end. All of this adds up to a real problem for hard-worked network managers, who are coming under more and more pressure to maintain the everyday running of the enterprise network while protecting it from multiple different threats to its well-being. One mistake could bring an entire business down for days, and in some cases, this can prove fatal. In this guide we will explore some of the key themes driving enterprise network security initiatives, from how to protect and monitor day-to-day activity on the network, to tips on how to defend it from malicious external attackers, and the effect that emerging networking technologies, such as the Internet of Things (IoT) and software-defined networking (SDN) will have on enterprise network security, and how to adapt to face these changing realities.

Focus: Securing the cloud

While cloud services’ benefits of quick deployment and flexible scalability at a lower cost have driven enterprise adoption, security concerns continue to be a key factor in determining the extent and style of cloud adoption. However, for many enterprises the benefits outweigh the risks, and as a result, cloud adoption is still outpacing security capability. Cloud security processes in many companies are still relatively immature, according to some information security leaders. Already heavily-invested in cloud services, technology companies are stepping up efforts around security and the UK Government Digital Service (GDS) has published guidelines that it claims will make public cloud services safe for most government information and services. Despite these positive developments, the reality is that most apps are not enterprise ready from a security standpoint. In the light of the global rise in cyber crime,security experts warn that is more important than ever for applications developed on the widely-adopted Microsoft Azure platform to be secure by design.
