ACE Full Form Name
Full Form of ACE:
Access Control Entry
ACE Full Form is Access
Control Entry. The entries in a control list with the information of the
security user access rights are called Access control entries. Each access
control entry has a distinct indentify (ID), which helps to identify the
individual or a subject group. An access control list can have multiple access
control entries, with each one having a defined access rights to an individual
or different groups. The access control entries in ACL (Access Control List)
controls all the access to the objects that users or programs might use.
It defines who and at which level
can access the object and resources thus, ensuring optimum security in a
system. When a user accesses a system and tries to execute a particular
program, the systemdemands for rights and credentials of an user so as to allow
the access to the program. When the program tries to open an object the
credentials that are used to allow access are compared with the security
control of the user.
The ACE information is then
monitored by the security and then it is determined whether a user should be
permitted to access the program. Whenever one modifies an ACL, windows will
automatically construct an appropriate ACE which takes care of implementation
details. There are 6 type of ACEs three are generic and can be used in ACL
where as other three are object specific. ACE contains following Access
Control Information:
1. A Security
Identifier (SID) that identifies a user and grants permission
2. An Access Mask
that specifies access rights controlled by access control entry
3. A Flag that
indicates type of ACE
