What is IPSec sad?
One is the Security Association Database (SAD, referred to as TDB or TDB table throughout Open BSD’s IPSec source code) and the other is the Security Policy Database (SPD). They are similar in that given a number of selectors that describe some traffic, they deliver an entry that describes the processing needed.
What is the difference between SAD and SPD?
It’s often hard to distinguish the SPD and the SAD, since they are similar in concept. The main difference between them is that security policies are general while security associations are more specific. The security policies in the SPD may reference a particular security association in the SAD.
