Read about: Encryption – critical in any defence strategy
Encryption is a critical component of a defence-in-depth strategy, which is a security approach with a series of designed defensive mechanisms. It means if one security mechanism fails, there is at least one more still operating. As more organisations look to operate faster and at scale, they need ways to meet critical compliance requirements and improve data security. Encryption, when used correctly, can provide an additional layer of protection above basic access control.

How AI will reshape leadership practices in a post-COVID-19 global economy
Advances in Artificial Intelligence (AI) are accelerating at an unprecedented pace. Today, business leaders are able to augment their decision-making and problem-solving capabilities through a myriad of capabilities powered by AI. With a continued rise in the adoption of Industry 4.0 technologies such as Internet of Things (IoT), Analytics, Machine Learning and Big Data, organisations have access to many data sources across their entire ecosystem, which previously was not always available to them.

Studying space weather is important to the SA economy
Space weather has its origin on the Sun resulting in various types of disturbances, such as the 21 May 1921 magnetic storm which is primarily driven by the interaction of the solar wind with the coupled magnetosphere-ionosphere system. It is however on the surface of the Earth that the implications of space weather effects are experienced in our inter-connected society. Ground-based geomagnetism networks therefore play an important role in the monitoring of space weather. In this manuscript Dr P B Kotzé, SANSA Space Science, discusses the impact of the geomagnetic observation network under the auspices of the South African National Space Agency (SANSA) to monitor the behaviour of the Earth’s magnetic field of particular importance to space weather applications in southern Africa.

Three energy trends for data centres
In 2017, a group of researchers estimated global data centres could use 25% of the world’s electricity by 2025. This is more electricity than any country in the world, including the US. This prediction is not materialising thus far, and raises the question of how much energy and electricity data centres consume? The world’s data centres consume around 200 Terawatt-hours (TWh) of energy annually, almost all of it electricity, accounting for about 1% of the world’s electricity consumption. While this is much lower than the prediction, it still makes data centres a considerable consumer of energy. However, the data centre industry has made significant progress to improve its energy efficiency. This has resulted in a plateau in data centre energy consumption in recent years. What is even more exciting is the industry’s ability to achieve such a plateau while successfully meeting its customers increased need for services. In this article Deepa Rungasamy, Cummins Communications Manager, explores three data centre energy trends.
