Final answer:
A security descriptor defines the type and contents of security attributes associated with an object. Option D is correct.
Step-by-step explanation:
A security descriptor in computing defines the type and contents of security attributes associated with an object. The type and contents of a security descriptor include:
DACLs (Discretionary Access Control Lists): These lists specify the permissions granted or denied to users and groups on an object.
SACLs (System Access Control Lists): These lists specify the types of security events that should be audited for the object.
Owners: The owner of an object is a security principal who has control over the object's discretionary access control.
Flags: These are used to control various aspects of the security descriptor, such as inheritance and auditing.
The type and contents of a security descriptor are defined by Discretionary Access Control Lists (DACLs) and System Access Control Lists (SACLs). Among the options provided, the correct answer is D) DACLs. A DACL is a component of a security descriptor that grants or denies access to securable objects to users and groups. Each entry in a DACL is an access control entry (ACE) that specifies the permissions for a user or group. On the other hand, a SACL controls how access attempts to the object are audited.
