The IP Security Protocol (Linux Journal)
[Posted September 9, 2002 by ris]
This Linux Journal article
explains
IPSec, different levels of security and how to be safe sending and
receiving packets over the network. "
Several different solutions
exist that allow us to cope with this problem, each operating at a
different level of abstraction. In this article, we will discuss the
differences between and purposes of application-level security,
socket-level security and network-level security."
This article continues with part 2 which
moves on to encapsulating security payloads and key exchange mechanisms.
