IPSec

Short for: IP Security

Taken from http://openbsd.org/faq/faq13.html:

“IPsec is a set of extensions to the IP protocol family. It provides cryptographic security services. These services allow for authentication, integrity, access control, and confidentiality. IPsec provides similar services as SSL, but at the network layer, in a way that is completely transparent to your applications, and much more powerful. We say this because your applications do not have to have any knowledge of IPsec to be able to use it. You can use any IP protocol over IPsec. You can create encrypted tunnels (Virtual Private Networks), or just do encryption between computers. Since you have so many options, IPsec is rather complex (much more so then SSL!)”
