The National Cyber Security Centre has reported a record number of sign-ups for its summer courses, which aim to teach young people key cybersecurity skills. CyberFirst teaches students how to analyse common attacks, crack codes, and defend their devices or networks. The courses, available for 14 to 17-year-olds, had to be moved online, which has proved fortuitous as 1,700 pupils are due to sign up. The scheme is part of efforts to improve diversity in STEM careers.
