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 )

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
.

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 )
