Multi-Factor Authentication – A Simple Step That Stops Hackers

Article Topic: “Why MFA (Multi-Factor Authentication) is No Longer Optional”


This week, I explored a short but important article from the Cybersecurity & Infrastructure Security Agency (CISA) about Multi-Factor Authentication (MFA).



 What is MFA?

Multi-Factor Authentication means using more than one method to log into your account like a password plus a code sent to your phone. It adds an extra layer of security even if your password is stolen.


Key Points I Learned:

  • MFA blocks 99% of automated attacks

  • It's now available on most major platforms like Google, Apple, and banks

  • Cybercriminals rely on stolen passwords, but MFA stops them


My Reflection:

This article helped me understand how simple but powerful Multi-Factor Authentication (MFA) really is when it comes to protecting accounts. Before reading it, I assumed that having a strong password was enough to keep my information safe. But now I realize that even strong passwords can be stolen through phishing attacks, data breaches, or malware and once that happens, attackers can access your accounts without you even knowing.

MFA works by requiring something you know (like your password) and something you have (like a code sent to your phone, a fingerprint, or a hardware token). That second layer can stop a hacker even if they have your password.

For example, I recently enabled MFA on my Google account using Google Authenticator. Now, even if someone guesses or steals my password, they still can’t log in without my phone. I also set it up on my school email and GitHub, which was surprisingly easy and took less than five minutes.

As a cybersecurity student, I see MFA not just as a personal tool, but as a critical defense in both personal and enterprise security. Many cyberattacks today begin with stolen login credentials — and MFA is one of the simplest ways to stop them. Going forward, I will make sure to enable MFA on every account that supports it, and I’ll also encourage friends, family, and future clients to do the same.

    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.

The Dark Web: What It Is and Why It Matters in Cybersecurity

-

What It Is: The Dark Web is a hidden part of the internet that you can’t find using normal search engines like Google. To access it, you need special software like the Tor browser. This browser hides your identity and location, so people can go online without being tracked. That’s why the Dark Web is known for anonymous communication. Some people use it for privacy, but others use it for bad reasons. Why It Matters in Cybersecurity: The Dark Web is important in cybersecurity because it’s often used by cybercriminals. They sell stolen data like usernames, passwords, and credit card numbers. You can also find hacking tools and malware there. Cybersecurity experts monitor the Dark Web to find out about new threats before they happen. This helps protect people, businesses, and organizations. It also helps law enforcement track down and stop criminals who use the Dark Web to plan or carry out attacks. In short: Even though the Dark Web is not always bad, it’s often linked to dangerous ...
