Securing the Cloud - Image by Free Photos from Pixabay-2020 has been the year of COVID-19, with new norms for organisations relying on geographically separated workforces. It has seen a significant uptake in cloud-based applications and services to keep businesses operating. At the top of this list has been virtual communication technologies. Products such as Microsoft Teams, Zoom and similar collaboration platforms have been almost universally adopted. Document sharing, personnel management, and financial applications are not far behind.

COVID-19 lockdown restrictions arrived very quickly. Organisations which had not proactively prepared a business continuity plan had to make quick procurement decisions for the products and services needed to keep trading. Others required undertaking a formal review of privacy policies. It meant understanding the geographic location of processed and store data. Just as important was assessing whether the cloud service provider would willingly support GDPR requirements. Notifying breach reports and cooperating with data subject right requests has become a secondary consideration to “how much” and “how soon”.

What are the best practices?

Organisations need to decide on what is the best practice for in-house services. It means assessing technical resilience, software patching, user access management and data backups. Whilst cloud services are essentially “data processed on somebody else’s server”, responsibilities remain with the data controller and still need to be considered. Sadly, that is where most risk assessments fail.

Many cloud service providers will willingly share their security and data protection controls. Worryingly, however, most potential customers either do not know that this information exists or fail to understand the importance of reviewing it. The UK Government’s National Cyber Security Centre has published “14 Cloud Security Principles.” These focus on the main areas which should be considered, from the perspective of the organisation providing the cloud service, and potential consumers.

The role of ISO 27001

ISO27001 is the most used standard for providing information security. It extends to the activities that may affect its confidentiality, integrity, or availability. Moving from an in-house managed capability to a cloud service will change the overall assessment of risk. This is because at least part of the protection for the valuable data being entrusted to the cloud will pass to the cloud service provider. The same is true for the physical data centre provider for software-as-a-service “SaaS” applications. It is exceedingly difficult to physically assess such third-party activities. It makes the reliance on contractual clauses and supporting evidence even more important.

Customers do not need to be aiming for formal ISO27001 certification to benefit from the best practice security controls that it contains within its “Annex A”. These can be considered in the context of an external cloud service (typically SaaS offerings). Importantly, more focused guidance can be found within the supplementary controls within the ISO27017 standard. Helpfully, this framework introduces the different role and responsibilities of the supplier (e.g. technical responsibilities for keeping the cloud service secure). It also defines the customer responsibilities (e.g. understanding the capabilities and limitations of a cloud service and guidance on how to consume it securely).

The long term impact of COVID-19

COVID-19 is likely to persist for a while to come. Organisations should take the time to identify those hasty lockdown decisions that may have been taken. It is also an opportunity to revisit the security of data which now finds itself in the cloud. A further consideration is to re-assess the workforce’s readiness for using the cloud. Is human error (most commonly caused by ignorance of published policy) challenging the organisation’s risk posture?

Assessments of the security of home workers must address several key areas. They will be on the outside of the strong perimeter and network controls which are in place within most corporate premises. Do individuals understand the organisation’s posture of using virtual private networks (VPNs) to secure communications? What about the requirements of the acceptable use policy (AUP) governing what software can and cannot be installed? Is there clear communication of how personal (BYOD) devices can (or cannot) be used for business purposes? All of these considerations are most usefully served up in an updated training session. This, of course, can be delivered remotely to ensure maximum participation.

Cloud services have certainly assisted many organisations in keeping trading during these difficult times. However, this “new normal” brings different and changing risks which need to be managed and controlled. There is no better time to take a look at these than now. Proactive prevention is always significantly better than reactive investigations. Nobody wants to risk losing the trust of valuable customers and the inevitable effect on that all too vulnerable revenue stream.

An experienced and innovative IT and Communications engineer, Andy graduated with a first-class honours in Computer Systems from the University of Salford. He spent the first 10 years of his career as an engineering officer in the Royal Navy, gaining extensive experience of service delivery, often in demanding circumstances. His naval career was spent in a wide variety of positions, from heading-up the IT department of an aircraft career, to implementing critical communications systems ashore in support of military operations. During his time as an engineer in the Royal Navy he learnt intimately the challenges of information security, not just technically, but also more importantly the process and people aspect. He realised that whilst there were many technical solutions, there was a big gap in the market for software to manage information security and ensure its robust and effective organisation and processes. On leaving the Navy, he used this knowledge and awareness to partner with other professionals in the industry to set up InfoSaaS. Andy has been involved in a number of other tech start-ups, including obtaining ISO27001 for those companies. Using InfoSaaS within these organisations significantly improved certification results and provided an opportunity to refine and enhance the solution's functionality.
