• Tips to Stay Safe Online

  • Be mindful of what you share online and what site you share it to
  • Do not just accept terms and conditions; read it
  • Check out the privacy policy page of a website to learn how the website handles the information you share
  • Know the security features of the social networking site you use. By keeping your profile private, search engines will not be able to scan your profile
  • Do not share your password with anyone
  • Avoid logging in to public networks/Wi-Fi. Browsing in “incognito mode” a feature of a browser, will not protect you from hackers
  • Do not talk to strangers whether online or face to face
  • Never post anything about a future vacation. It is similar to posting, “Rob my house at this date”
  • Add friends you know in real life
  • Avoid visiting untrusted websites
  • Install and update an antivirus software on your computer. Use only one anti-virus to avoid conflicts
  • If you have a Wi-Fi at home, make it a private network by adding a password
  • Avoid downloading anything from untrusted websites. You are most vulnerable in peer-to-peer downloads (torrents) as the download is most likely not monitored by the site owner
  • Buy software; do not use pirated ones
  • Do not reply or click links from suspicious emails
• Online Safety and Security: 'The internet is one of the most dangerous places, especially if you do not know what you are doing with it. The internet, truly, is a powerful tool. It can be used to promote your business, gain new friends, and stay in touch with the old ones. It is also a source of entertainment through games, online communities and everything in between. But most like things in this world, there is always the “other side of the coin”'

• Think Before You Click: 'Before you post something on the web, ask these questions to yourself: Would you want your parents or grandparents to see it? Would you want your future boss to see it? Once you post something on the web, you have no control of who sees your posts. Your friends depend on you to protect their reputation online. Talk to your friends about this serious responsibility'
