Cloud computing has been a great enabler for a great many companies and individuals in the decade or so since it gained traction. The ability to access new systems rapidly without concern for forward planning, accessing corporate budgets and in particular the ability to scale up (or down) on demand has proved particularly attractive. A great many researchers have been actively involved to ensure that systems are developed in a responsible way to ensure the security and privacy of users.

However, there remains a fundamental issue which is of great concern. Namely, that once an attacker successfully breaches a cloud system and becomes an intruder, usually escalating privileges the longer they are in the system, there is nothing then to prevent them from deleting or modifying the forensic trail. This presents a serious challenge, and in the light of the forthcoming regulation from various countries, and of particular interest the forthcoming EU General Data Protection Regulation (GDPR), which has a regime of penalties that can rise up to the greater of €20 million or 4% of Global Turnover. The other challenging aspect of this legislation is that any security breach must be reported within 72 hours. For cloud users who are breached, particularly where the intruder deletes or modifies the forensic trail, this becomes a virtually impossible requirement to comply with, which can also lead to an increase in the fine levied.

Solving this problem presents a seriously difficult challenge, but without solving this problem, this leads to a serious issue with compliance on the EU GDPR and other similar legislation around the globe, which can lead to massive levels of fines being levied. Looking at the cyber breach reports regularly carried out each year by a number of security organizations, it is very clear that a great many companies are nowhere near being able to comply with this tight reporting requirement, let alone understand which records have been accessed, modified or deleted. Given that the regulation comes into effect on the 25th May 2018, it is clear that many companies are walking blind into a major disaster.

This panel will address the above issues and consequences.

In the Exascale era, a computing system is capable of processing at least one billion billion calculations per second. This higher level of performance in computing systems will have profound impacts on every aspect of current research communities, especially those in High Performance Computing (HPC) community.

Meanwhile, the rapid development of Cloud based technologies makes more applications possible. Furthermore, the techniques in Intelligent Systems and Analytics, especially Deep Learning, have matured enough to a degree that they are applicable to a variety of versatile research areas, including those in HPC.

This panel will discuss the opportunities and challenges in HPC that can be addressed by Intelligent Systems, Deep Learning, Clouds, and Analytics. Simultaneously, it will also attempt to discuss the opportunities and challenges in Intelligent Systems, Deep Learning, Clouds, and Analytics that can be addressed by HPC.

Bob Duncan has a background in accounting, with many decades of experience in industry, and has watched the development and implementation of IT systems over the decades. With a recent MA (Hons) in Computing and a PhD in Computing Science, specialising in Cloud Security, he has an avid interest in Cloud Cyber Security. He is particularly interested in Cloud systems from a security perspective, due to the possible opportunities offered by the flexibility of cloud systems, but is concerned as to how easy it is for corporates to lose sight of the security implications for their business. This is particularly problematic with the development of modern legislation and regulation concerning matters of data protection, and in particular, the forthcoming EU General Data Protection Regulation.
