Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services. [1] [2] Originally, only centralized domain management used Active Directory. However, it ultimately became an umbrella title for various directory-based identity ...
Microsoft's Active Directory service implements an LDAP server that store and disseminate configuration information about users and computers in a domain. [17] Active Directory extends the LDAP specification by adding the same type of access-control list mechanism as Windows NT uses for the NTFS filesystem. Windows 2000 then extended the syntax ...
NewSID ensures that this SID is in a standard NT 4.0 format (3 32-bit subauthorities preceded by three 32-bit authority fields). Next, NewSID generates a new random SID for the computer. NewSID's generation takes great pains to create a truly random 96-bit value, which replaces the 96-bits of the 3 subauthority values that make up a computer SID.
Ambiguous Name Resolution (ANR) is a feature available in Microsoft's Active Directory which allows resolution of multiple objects on a computer network based on limited input. The user will be able to select the correct entry from these results. To allow this feature to operate, attributes need to be ANR enabled in the directory schema.
AGDLP (an abbreviation of "account, global, domain local, permission") briefly summarizes Microsoft's recommendations for implementing role-based access controls (RBAC) using nested groups in a native-mode Active Directory (AD) domain: User and computer accounts are members of global groups that represent business roles, which are members of domain local groups that describe resource ...
Attribute-based access control or ABAC is a model which evolves from RBAC to consider additional attributes in addition to roles and groups. In ABAC, it is possible to use attributes of: the user e.g. citizenship, clearance, the resource e.g. classification, department, owner, the action, and; the context e.g. time, location, IP.
Active Directory: A set of technologies introduced with Windows 2000 that allows administrators to assign enterprise-wide policies, deploy apps to many computers, and apply critical updates to an entire organization. Active Directory stores information and settings relating to an organization in a central, organized, accessible database.
Attribute values can be set-valued or atomic-valued. Set-valued attributes contain more than one atomic value. Examples are role and project. Atomic-valued attributes contain only one atomic value. Examples are clearance and sensitivity. Attributes can be compared to static values or to one another, thus enabling relation-based access control.
