Principle of Least Privilege Examples for High School Students

📚 Quick Study Guide

• 🔑 Principle of Least Privilege (PoLP): The idea that every user, application, or process should only have the minimum access rights needed to do its job. No more, no less!
• 🛡️ Why it matters: Reduces the risk of damage from accidents, errors, or malicious attacks. If someone only has access to a small part of the system, they can't do as much harm.
• 💻 Real-world analogy: Think of it like your phone. You wouldn't give every app full access to everything on your phone, right? You only give them permission to access what they *really* need (like your camera for a photo app).
• ⚙️ How it works: Assign roles and permissions carefully. Regularly review and update these permissions as needed.
• ⚠️ Examples:
  • A student account on a school computer should only be able to access student files and applications, not administrative settings.
  • A guest user on a network should only have access to the internet, not shared files or printers.
