🧒 5살도 이해할 수 있게 설명
Imagine you want to send a secret drawing to a friend at school. Instead of just handing it to them, you put it in a lunchbox with a combination lock that only you and your friend know. Even if someone steals your lunchbox, they can't see your drawing. That secret lunchbox is like IPSec for your computer data.
🤓 Expert Deep Dive
Technically, IPSec implementation centers around the 'Security Association' (SA), a set of rules that two devices agree on for their secure communication. It uses 'IKE' (Internet Key Exchange) to securely set up these rules. In 'Transport Mode', only the payload of the IP packet is encrypted. In 'Tunnel Mode', the entire original packet—including the header—is encrypted and placed inside a new IP packet. This is critical for hiding the true source and destination of the traffic. IPSec is often contrasted with SSL/TLS (used for HTTPS); while SSL/TLS works at the Application layer, IPSec works at the Network layer, meaning it can protect any type of traffic without the application even knowing it exists.
