WGU D430 FINAL REVIEW QUESTIONS
VERIFIED COMPLETE ANSWERS 100
PERCENT CORRECT
◉ 3DES
Answer: Triple Digital Encryption Standard. A symmetric algorithm
used to encrypt data and provide confidentiality. It was originally
designed as a replacement for DES. It uses multiple keys and
multiple passes and is not as efficient as AES, but is still used in
some applications, such as when hardware doesn't support AES.
◉ AES
Answer: A set of symmetrical block ciphers endorsed by the us
government through NIST . Is used by a variety of organizations. It is
the replacement for DES as the standard encryption for us
government . Uses 3 different ciphers one a 128 bit key one 192-bit
key and one 256- bit key
◉ Symmetric block cipher programs
Answer: Two fish, serpent, blowfish , cat5, IDEA
◉ Stream cipher programs
Answer: RC4, ORXY, and SEAL
,◉ Elliptic Curve Cryptography (ECC)
Answer: A type of public key cryptosystem that requires a shorter
key length than many other cryptography systems (including the de
facto industry standard, RSA).
◉ Protecting data at rest
Answer: Data is at ready when it is on a storage device of some kind
and is not moving over a network, or a protocol
◉ Data security
Answer: The process of keeping data, both in transit and at rest, safe
from unauthorized access, alteration, or destruction
◉ Protecting Data in Motion
Answer: The primary method of securing data from exposure on
network media is encryption, and we may choose to apply it in one
of two main ways: by encrypting the data itself to protect it or by
protecting the entire connection.
◉ Protecting data itself
Answer: SLL&TLS are used to protect info sent over the network and
over internet. The operate in conjunction with other protocols like
, internet message access protocol (IMAP) , post office protocol (POP)
for email
◉ VPN (Virtual Private Network)
Answer: A private network that is configured within a public
network such as the Internet. A secure connection between two
systems
◉ Internet Protocol security (IPSEC)
Answer: A set of protocols developed to support the secure exchange
of packets between hosts or networks.
◉ Protecting data in use
Answer: Hardest to protect. Data is in use when a user is accessing
the data.
◉ FISMA
Answer: Federal Information Security Management Act provides a
framework for ensuring the effectiveness of information security
controls in government
◉ FERPA
Answer: Family Educational Rights and Privacy Act. Protects the
privacy of students and parents
