Interactive Exercise: Personal Risk Assessment

High-Risk Factors (Critical — Address Immediately)

• Using simple or reused passwords like 'password123' or your birthday across multiple accounts
• Not using two-factor authentication on email, banking, or social media accounts
• Frequently connecting to public Wi-Fi networks without a VPN (coffee shops, airports, hotels)
• Clicking on links or downloading attachments from unfamiliar emails without verifying the sender
• Not keeping your operating system, browser, and applications updated with security patches

Medium-Risk Factors (Important — Plan to Fix)

• Sharing excessive personal information on social media (location, workplace, daily routines)
• Not backing up important data regularly to a secure external or cloud location
• Using default or weak privacy settings on social media and online accounts
• Not having antivirus or endpoint protection software installed on your devices
• Using shared or public computers to access personal accounts

Low-Risk Indicators (Good Practices — Keep Doing These)

• Using unique, strong passwords for every account (ideally with a password manager)
• Keeping all devices, browsers, and applications updated automatically
• Using secure, private networks and a VPN on untrusted connections
• Being cautious with links, downloads, and email attachments from unknown sources
• Regularly backing up data and verifying that backups can be restored
