IPsec: Secure Internet Data Transmission 🔒

When data travels across the internet, it can be exposed to hackers. IPsec (Internet Protocol Security) keeps it safe.

IPsec is a set of protocols that:

Encrypts IP packets for privacy

Authenticates data to prevent tampering

Secures VPNs and private communication

Think of it like sending a locked and sealed package instead of a postcard — only the right person with the key can open it.

Essential for CCNA learners, cybersecurity students, and anyone learning about secure networking.
