User Account Control (UAC) is a mandatory access control enforcement feature introduced with Microsoft's Windows Vista [1] and Windows Server 2008 operating systems, with a more relaxed [2] version also present in Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, Windows 8.1, Windows Server 2012 R2, Windows 10, and Windows 11.
Mandatory Integrity Control is defined using a new access control entry (ACE) type to represent the object's IL in its security descriptor.In Windows, Access Control Lists (ACLs) are used to grant access rights (read, write, and execute permissions) and privileges to users or groups.
In some systems, users have the authority to decide whether to grant access to any other user. To allow that, all users have clearances for all data. This is not necessarily true of an MLS system. If individuals or processes exist that may be denied access to any of the data in the system environment, then the system must be trusted to enforce MAC.
Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously ...
Local Security Authority Subsystem Service (LSASS) [1] is a process in Microsoft Windows operating systems that is responsible for enforcing the security policy on the system. It verifies users logging on to a Windows computer or server, handles password changes, and creates access tokens. [2] It also writes to the Windows Security Log.
Privileged Access Management (PAM) is a type of identity management and branch of cybersecurity that focuses on the control, monitoring, and protection of privileged accounts within an organization. Accounts with privileged status grant users enhanced permissions, making them prime targets for attackers due to their extensive access to vital ...
Discretionary access control is commonly discussed in contrast to mandatory access control (MAC). Occasionally, a system as a whole is said to have "discretionary" or "purely discretionary" access control when that system lacks mandatory access control. On the other hand, systems can implement both MAC and DAC simultaneously, where DAC refers ...
User Interface Privilege Isolation (UIPI) is a technology introduced in Windows Vista and Windows Server 2008 to combat shatter attack exploits. By making use of Mandatory Integrity Control , it prevents processes with a lower "integrity level" (IL) from sending messages to higher IL processes (except for a very specific set of UI messages).
