University students can use their knowledge of encryption to make their campus networks safer. Here’s how:

1. What is Encryption?

• Definition: Encryption is a way to change regular information (called plaintext) into a secret code (called ciphertext) so that only people with the right key can read it. This is really important for keeping private information safe, especially at universities where there’s a lot of personal and school data.
• History: Encryption has a long history. It started with simple codes like the Caesar cipher and has grown into more advanced methods like the Advanced Encryption Standard (AES). AES was adopted by the U.S. government in 2001 and uses different key sizes (128, 192, or 256 bits). It’s very secure and hard for hackers to break.

2. Why is Encryption Important for Network Security?

• Protecting Data: A report from Cybersecurity Ventures says that by 2031, ransomware attacks could cost businesses and schools $265 billion. Good encryption can help protect against these kinds of attacks by making sure that stolen data is unreadable without the right key.
• Keeping Information Safe: Cyberattacks are increasing, especially on schools, which saw a 30% rise in 2021. By using encryption, students and staff can keep emails, research data, and private school records safe from being intercepted or altered.

3. How Can Students Use Encryption?

• Secure Communication: Students can use encryption tools like TLS to make sure their data stays safe when working together on projects or research.
• Protecting Stored Data: It’s important to encrypt important files on personal devices or on campus networks to keep them safe from unwanted access.

Conclusion

By using these encryption methods, students can help make their university’s network security much stronger.
