NIST SP 800-192 under Discretionary access control (DAC) A means of restricting access to objects (e.g., files, data entities) based on the identity and need-to-know of subjects (e.g., users, processes) and/or groups to which the object belongs Discretionary access control (DAC) is a model of access control based on access being determined by the owner of the resource in question. The owner of the resource can decide who does and does not have access, and exactly what access they are allowed to have. In Microsoft operating systems, we can see DAC implemented

Discretionary access control (DAC) is a type of security access control that grants or restricts object access via an access policy determined by an object's owner group and/or subjects. DAC mechanism controls are defined by user identification with supplied credentials during authentication, such as username and password 임의적 접근통제 DAC 에 대해 알아봅시다. * 임의적 접근통제 (DAC, Discretionary Access Control) 란? 어떤 사용자든지 임의적으로 다른 객체에 접근할 수 있도록 허용하는 기법을 임의적 접근통제라고 한다. 기본 개념은 이렇고. 그냥 쉽게. Discretionary access control can operate in conjunction with mandatory access control as described in AC-3 (3) and AC-3 (15). A subject that is constrained in its operation by mandatory access control policies can still operate under the less rigorous constraints of discretionary access control 임의적 접근통제 (DAC, Discretionary Access Control) DAC 은 자원에 대한 접근을 사용자계정에 기반한다. 사용자는 자원과 관련된 ACL 이 수정됨으로써 자원 대한 권한을 부여 받는다

Discretionary Access Control (DAC) Filesystem objects and services added to the build frequently need separate, unique IDs, known as Android IDs (AIDs). Currently, many resources such as files and services use core (Android-defined) AIDs unnecessarily; in many cases you can use OEM (OEM-defined) AIDs instead A discretionary access control (DAC) policy is a means of assigning access rights based on rules specified by users. The underlying philosophy in DAC is that subjects can determine who has access to their objects. DAC policies includes the file permissions model implemented by nearly all operating systems In campo di sicurezza informatica, il discretionary access control (DAC) è un tipo di controllo d'accesso definito dalla Trusted Computer System Evaluation Criteria come una forma per limitare l'accesso a contenuto appartenente a soggetti e/o gruppi

Discretionary access control (DAC) is a paradigm of controlling accesses to resources. According to the trusted computer system evaluation criteria (TCSEC) (often referred to as the Orange Book)[], discretionary access control is a means of restricting access to objects based on the identity of subjects and/or groups to which they belong Discretionary access control (also called security scheme) is based on the concept of access rights (also called privileges) and mechanism for giving users such privileges. It grants the privileges (access rights) to users on different objects, including the capability to access specific data files, records or fields in a specified mode, such as, read, insert, delete or update or combination. A discretionary access control list (DACL) identifies the trustees that are allowed or denied access to a securable object. When a process tries to access a securable object, the system checks the ACEs in the object's DACL to determine whether to grant access to it. If the object does not have a DACL, the system grants full access to everyone

When discretionary access control policies are implemented, subjects are not constrained with regard to what actions they can take with information for which they have already been granted access. Thus, subjects that have been granted access to information are not prevented from passing (i.e., the subjects have the discretion to pass) the information to other subjects or objects Access control models are based on requirements, technology, and implementations. Different types of access control models exist. The most popular access control models are a Discretionary Access Control (DAC), Mandatory Access Control (MAC), Role Based Access Control (RBAC), and Attribute Based Access Control (ABAC) Discretionary Access Controls, also known as DAC, are types of cybersecurity measures that allow or restrict access based upon the discretion of the file or resource owner.For example, if Bob owns a file or resource, then Bob can, at his discretion grant access to Susie and deny access to Jennifer.
