In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1]
In computer security, discretionary access control (DAC) is a type of access control defined by the Trusted Computer System Evaluation Criteria [1] (TCSEC) as a means of restricting access to objects based on the identity of subjects and/or groups to which they belong.
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.

A real attack could have destroyed the unit much more quickly. [6] For example, a generator built without a rotating rubber coupling between the diesel engine and the alternator would experience the crankshaft-destroying abnormal forces in its diesel engine immediately, given the absence of a shock-absorbing material between these two rotating ...
Also in June 2021, MIT researchers revealed the PACMAN attack on Pointer Authentication Codes (PAC) in ARM v8.3A. [35] [36] [37] In August 2021 a vulnerability called "Transient Execution of Non-canonical Accesses" affecting certain AMD CPUs was disclosed.
