Cyber resilience in a hybrid workplace: securing your employees’ devices

As reported by a Unisys study, 64% of business leaders indicated that their organisation planned to adopt a different operating model than the one they had in place before the COVID-19 pandemic.

The zero trust network model is exactly what the name implies: trust nothing.

While flexible working conditions are reported to drive productivity and help with mental wellbeing for staff, there are challenges around this new way of working – one of the biggest being cybersecurity. As outlined in the 2021 Cybersecurity Breach Survey published by the UK government, transitioning to a hybrid or even fully remote working model has brought some new challenges for businesses and organisations when it comes to staying fully protected against cyber attacks. This includes increased difficulty in user monitoring, keeping hardware and software systems updated, and extending security measures to personal devices, just to name a few…READ ON

Satellite data used to create 3D images of Earth, detecting natural disasters

Researchers have developed a way to use satellite imaging data to create 3D images that could quickly detect changes on the Earth’s surface.

Planetscope’s data is open access to educators, allowing other scientists to use the same datasets the study used to create their own simulations.

The Planetscope satellite constellation, operated by the satellite data company Planet collects weekly and sometimes even daily images of the entire globe. Its fleet of Cubesats, or miniature satellites, has about 1,700 images of every location on Earth. The data the constellation captures has been used to monitor the spread of wildfires, detect changes in crop health and survey areas of deforestation.

A group of researchers have found a way to utilise this data to detect significant natural disasters in remote regions of the globe soon after they happen, giving first responders accurate information about the needs of the region affected.

This kind of global coverage is unprecedented, said associate professor Rongjun Qin: “There are a lot of great benefits in terms of having satellites cover the globe very quickly. We’re focused on informing the community about changes to our cities, forests and ecosystems.”…READ ON
