Access control is an important security measure that helps protect data and systems from unauthorized access. It is used to limit who can access certain resources and what they can do with them. There are three main types of access control: discretionary, mandatory, and role-based. In this blog post, we will discuss each type in detail and explain how they work.
Discretionary Access Control (DAC) is the most common type of access control. It allows users to control who can access their data or system resources based on their own discretion. With DAC, users have full control over who can access their data or system resources and what actions they can take with them. For example, a user may decide to allow only certain people to view a file or folder, while others may be restricted from viewing it.
Mandatory Access Control (MAC) is a type of access control that uses labels to define the level of security for each resource or system component. With MAC, users are assigned labels based on their clearance level or job role. These labels determine which resources they are allowed to access and what actions they can take with them. For example, a user with a “confidential” label may be allowed to view certain confidential documents but not allowed to modify them in any way.
Role-Based Access Control (RBAC) is a type of access control that assigns roles to users based on their job function or responsibility within an organization. With RBAC, users are granted specific permissions based on their role within the organization. For example, an administrator may be granted full access to all system resources while an end user may only be granted limited permissions such as viewing documents or running specific programs.
Access control is an important security measure that helps protect data and systems from unauthorized access. There are three main types of access control: discretionary, mandatory, and role-based. Each type has its own advantages and disadvantages depending on the needs of the organization or individual user. Understanding these different types of access control will help you make informed decisions when it comes to protecting your data and systems from unauthorized use or manipulation.
