Which implements mainly access control matrixes?
A.
Mandatory
B.
Centralized
C.
Decentralized
D.
Discretionary
Explanation:
DAC is implemented and enforce through the use of access control lists (ACLs), which are held in a matrix. MAC is implemented and enforced through the use of security labels.
Mandatory access controls (MACs) are those controls determined by the system and based primarily on organization policy. The answer should be A.
it should be Discretionary reason it maps subjects (users) with rights on objects (capabilities).
Agreed, it is DAC. Per Harris:
“An access control matrix is a table of subjects and objects indicating what actions individual subjects can take upon individual objects. Matrices are data structures that programmers implement as table lookups that will be used and enforced by the operating system. Table 4-1 provides an example of an access control matrix.
**This type of access control is usually an attribute of DAC models. The access rights can be assigned directly to the subjects capabilities) or to the objects (ACLs).**”
