A digital footprint is a term used to describe the data that’s left behind whenever a person uses a digital service. It’s normal to have a digital footprint, and everyone is likely to have one.  However, if it's not protected properly, it can leave you vulnerable to attacks. Remember, once something is shared online, it can be there forever. 

Hear from John at National Cyber Security Centre (NCSC) on how to keep your digital footprint safe.
