This type of Access controls refers to allowing some access to our resource, but only up to a certain point.

• Allowing access

• Denying access

• Limiting access

• Revocation of access

What is authorization?

• The process of breaking through the encryption used to create the ciphertext

• The process of recovering the plaintext message from the ciphertext

• The process of establishing a claim of identity as being true

• The process of determining what a party is allowed to do

What is the purpose of access controls?

• To allow access to a resource

• To deny access to a resource

• To limit access to a resource

• All of the above

What is discretionary access control (DAC)?

• Access control based on access being determined by the owner of the resource

• Access control based on access controls set by an authority responsible for doing so

• Access control in which the owner of the resource does not get to decide who gets to access it

• Access control based on attributes of a person, resource, or environment
