This document discusses several issues related to internet use, including:
1. There is no single organization that controls the internet, so anyone can create websites and publish information without verification, allowing for misinformation to spread.
2. To avoid undesirable content, some organizations and parents use webpage filtering software, but people can also be careful about the links and search terms they use.
3. When sending sensitive data online, it's important to use encryption and digital certificates to keep information secure, as well as having strong passwords and firewall protection.
