With that said the amount of granularity can be daunting to a newcomer.SIDs are just variable length strings of alphanumeric characters that represent machines, users and groups.
SIDs are added to ACLs(Access Control Lists) every time you grant a user or group permission to a file or folder. Behind the scene SIDs are stored the same way all other data object are, in binary. However when you see a SID in Windows it will be displayed using a more readable syntax. It is not often that you will see any form of SID in Windows, the most common scenario is when you grant someone permission to a resource, then their user account is deleted, it will then show up as a SID in the ACL. So lets take a look at the typical format in which you will see SIDs in Windows. This is prefixed to all SIDs and is there to inform Windows that what follows is a SID. The second component of a SID is the revision number of the SID specification, if the SID specification was to change it would provide backwards compatibility. The third section of a SID is called the Identifier Authority. In our example this is used to identify the local machine, but could also be the the identifier for a Domain. Security principals can be local or be in the domain context. You manage local security principals through the Local Users and Groups snap-in, under computer management. To get there right click on the computer shortcut in the start menu and choose manage. Take note that when you share a folder by default the Everyone group is given the read permission. Security on folders is usually done with a combination of Share and NTFS Permission if this is the case it is essential to remember that the most restrictive always applies, for example if the share permission is set to Everyone Read(which is the default), but the NTFS Permission allow users to make a change to the file, the Share Permission will take preference and the users will not be allowed to make changes. When you set the permissions the LSASS(Local Security Authority) controls access to the resource. When you logon you are given an access token with your SID on it, when you go to access the resource the LSASS compares the SID that you added to the ACL (Access Control List) and if the SID is on the ACL it determines whether to allow or deny access. No matter what permissions you use there are differences so lets take a look to get a better understanding on when we should use what. They dont apply if you log on locally, for example through terminal services. If you want to provide a more granular sort of restriction scheme you should use NTFS Permission in addition to shared permissions. Read and ReadWrite. The idea was part of the whole Home group mentality and makes it easy share a folder for non computer literate people. This is done via the context menu and shares with your home group easily.
