It contains things like who has access, what they can do, and when they can, basically everything that helps protect your data from unauthorized access. The SDDL is how we store that information in a string format to easily compare it against other strings containing similar information. For example, if we try to figure out whether two people have equal permissions on something, I can use their SDDLs as part of my comparison process!
