🔐 Week 5: Zero Trust Security — Why "Trust No One" Is the New Rule in Cybersecurity

-

 

Hey everyone! 👋

Welcome back to the Cyber Secure Weekly Blog! This week, we’re talking about something really important in the world of cybersecurity: Zero Trust Security.

🌐 What Is Zero Trust Security?

Zero Trust is a new way of protecting networks. The old way was to trust people or devices inside your network and only check outsiders. But today, hackers are getting smarter, and attacks can come from anywhere even inside your company.

So, Zero Trust says:

"Never trust, always verify."

This means you should check everyone and everything before giving access to your systems or data no matter where they are.


🔑 Key Ideas of Zero Trust

Here are some of the main ideas behind Zero Trust:

  • ✅ Verify every time – Don’t trust users or devices just because they’re in the network.

  • 🔐 Give only what’s needed – People should only have access to what they need to do their job.

  • 🚨 Assume breaches happen – Always be ready in case someone gets in.

  • 🧱 Break up your network – Divide it into small sections so hackers can’t move around easily.

  • 👁️‍🗨️ Watch everything – Keep track of who logs in and what they’re doing.

💡 Why Is Zero Trust Important?

Zero Trust is important because the way we work has changed:

  • People work from home more.

  • We use cloud services (like Google Drive or Microsoft Teams).

  • Cyberattacks are getting more common and more dangerous.

Hackers no longer have to break into a network — sometimes they already have a way in. That’s why checking every request is so important.

🛠️ How Do You Use Zero Trust?

Here are some ways companies use Zero Trust in real life:

  1. Use strong passwords and multi-factor authentication (MFA)
    ➤ This means even if someone steals your password, they still can’t log in.

  2. Check devices
    ➤ Make sure phones and computers are safe before they connect to your network.

  3. Block parts of the network
    ➤ Don’t let people go everywhere — only where they’re allowed.

  4. Use smart rules
    ➤ Only allow access based on where the person is, what device they’re using, and the time of day.

  5. Keep watching and updating
    ➤ Always review who has access and remove people who don’t need it anymore.

📊 Real-Life Examples

  • 🏦 Some banks use Zero Trust and have stopped many cyberattacks.

  • 💼 Big companies like Google and Microsoft are using Zero Trust to keep their data safe.

  • 💸 Businesses save money on cyberattack costs when they use Zero Trust.

⚠️ Things to Keep in Mind

Zero Trust is great, but it can take time and effort to set up. It’s not just one tool you can buy it’s a way of thinking and protecting your digital world.

✅ Final Thoughts

Zero Trust might sound a little scary “trust no one?” but it’s actually about keeping everyone safe. In today’s world, it’s better to be careful than sorry. So next time you log in somewhere, remember: verify first, then trust.

Thanks for reading! 🙌
Stay safe, stay smart, and I’ll see you in next week’s blog post! 😊💻

    This week, I learned about ransomware . Ransomware is a type of virus that locks your computer or files. Then the hacker asks for money (a ransom) to unlock them. This is very dangerous because it can stop people from using their computers. Many hospitals, schools, and companies have been attacked with ransomware. Here is an article I read: 🔗 What Is Ransomware? | IBM What I learned: I learned that ransomware can come from bad emails or fake websites. If you click on a bad link, the virus can start. To stay safe, we should not click strange links and always back up our files.

What I Hope to Learn About Cybersecurity This Semester

-
As I begin this Computer Security course ( CYBR 332), I’m really excited because it will teach me how to keep information safe from hackers and other threats. In this class, I’ll learn about lots of important things like: Different types of security problems and how to stop them How to control who can access important information How encryption ( secret codes) helps protect data Why privacy matters and the rules we should follow How to keep computer files and networks safe from attacks What I like most is that this course has hands- on labs, so I can practice the skills instead of just reading about them. I hope by the end of the semester, I will know how to protect computers and networks better and be ready for a job in cybersecurity. I’m excited to share what I learn and some cool articles about security with everyone here!
