How do NAT and VPN work?

NAT

the traffic is visible to the VPN provider. But, VPN can enhance privacy and security in the following manner :

  • It uses encryption techniques to encrypt the network packets so that if an attacker sniffs the packets, he can only see the encrypted data.
  • It uses authentication to prevent unauthorized users from accessing the VPN.
  • It provides message integrity to detect the modification of transmitted data.

Interested readers will get more information on NAT and VPN here:

I hope this helps. Interested readers who want to know more about how different malware and cyberattacks work and how we can prevent them may want to refer to the book “A Guide To Cyber Security.”

Security Fundamentals Practice Tests

The Security Fundamentals Practice Tests test one’s fundamental knowledge of cyber security. They are good for those preparing for various certification exams, such as the CCNA, CCNP, or CompTIA, and for students and IT/security professionals who want to improve their understanding of cybersecurity.
