Cyber safety refers to safely using the internet while protecting personal information. It is important to be aware of potential dangers like identity theft, where someone steals personal details to pose as another person online. Websites can track users using their IP address, browser history, cookies, and other methods to build profiles for targeted advertising. Users should practice safe browsing habits, use private browsing when possible, and adjust privacy settings to control what information is visible to others online to avoid identity fraud or privacy violations. Digital footprints created by all online activities are permanent, so caution is needed regarding what information is shared or posted.
