6. Future Learn
The Introduction to Cyber Security course from Future Learn, owned by the UK-based Open University, is available to take at any time on any schedule, and is accredited by UK Government intelligence organization GCHQ, global accreditation and examination institute APMG International, and The Institute of Information Security Professionals.
Future Learn also offers a free three-week online course called Cyber Security: Safety at Home, Online, in Life, designed to teach the essentials of maintaining security and privacy online and at home.
However, FutureLearn courses tend to provide general overviews and introductions rather than detailed technical explorations of the subject, so don’t expect to need to learn Python programming in these courses.
