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).**”
