Our personal attitude and behavior is the best protection when using the internet. When connecting to search for webpages, a user's computer first connects to an internet service provider who assigns an IP address. The user then opens a browser, types a URL, and their request is sent to a DNS server to locate the corresponding server hosting the requested webpage. The server then sends the webpage back to the user's computer in packets which are reassembled and displayed in their browser. Key tools to enhance security include antivirus software, firewalls, strong passwords, and taking care to avoid phishing, cyberbullying or sharing private information. Everything done online contributes to our digital footprint which traces our digital identity over time.
