3DES - CORRECT ANSWER: DES used to encrypt each block three times , each with

a different key

Access Control List - CORRECT ANSWER: info about what kind of access certain

parties are allowed to have to a given system

Read , write , execute

Access Control Models - CORRECT ANSWER: Discretionary ( DAC )

Mandatory ( MAC )

Rule - based

Role - based ( RBAC )

Attribute - based ( ABAC )

Accountability - CORRECT ANSWER: Refers to making sure that a person is

responsible for their actions .

-It provides us with the means to trace activities in our environment back to their source

.

-Depends on identification , authentication , and access control being present so that we

Asymmetric cryptography - CORRECT ANSWER: a public key and a private key . The

public key is used to encrypt data sent from the sender to the receiver and is shared

with everyone . Private keys are used to decrypt data that arrives at the receiving end

and are very carefully guarded by the receive ( aka the public key cryptography )

Asymmetric Key Algorithms - CORRECT ANSWER: Secure Sockets Layer ( RSA )

Elliptic Curve Cryptography ( ECC )

Pretty Good Privacy ( PGP )

Transport Layer Security ( TLS )
