CIA Triad - ANSWER ✓ Confidentiality, Integrity, Availability (CIA) are
typically viewed as the primary goals and objectives of a security infrastructure.
Data Encryption Standard (DES) - ANSWER ✓ Developed by IBM at the request
of the U.S. Government, is a 64-bit data / 56-bit cryptographic symmetric key.
Triple DES (3DES) - ANSWER ✓ Is identical to DES but uses a double-length
key (128-bit) that encrypts, then encrypts, and then encrypts again (called
"folding"). Banks commonly use it.
Secure Hash Algorithm version 1 (SHA-1) - ANSWER ✓ Is specified for creating
a digest of a message or a dat file.
Secure Hash Algorithm version 3 (SHA-3) - ANSWER ✓ In 2007, NIST
announced a public competition to develop a new cryptographic hash algorithm for
standardization. The competition was NIST's response to advances made in the
cryptanalysis of has algorithms. In 2012, NIST announced Keccak the winner of
the 5 year competition.
Block Cipher - ANSWER ✓ An encryption method that encrypts data in fixed-
sized blocks. Used for encrypting bulk data such as files and batches of data as
well as storage systems. Types of encryption using this method are DES, 3DES,
and AES.
, Secure Sockets Layer (SSL) - ANSWER ✓ Most popular form of PPK and has
become the de facto standard for transporting private information across the
Internet.
Nonrepudiation - ANSWER ✓ Guarantees that the sender of a message cannot
deny having sent the message and the receiver cannot deny having received the
message.
Local Area Network (LAN) - ANSWER ✓ A network configuration designed for
a limited space or geographic area, such as a series of offices in the same building.
Wide Area Network (WAN) - ANSWER ✓ Spans a large geographic area such as
a state, province, or country
Internet - ANSWER ✓ An interconnection of different-sized networks (LANs)
around the world.
Intranet - ANSWER ✓ A local or wide area network based on TCP/IP, but with
fences (firewalls) that limit the network's access to the Internet. More secure than
internet because it has a restricted user community and local control.
Stateful Inspection - ANSWER ✓ Keeps track of the state of the current
connection to help ensure that only desired traffic passes through. Allows the
creation of one-way rules.
Packet-Filtering - ANSWER ✓ Yields a permit or deny decision for each packet it
receives. The router examines each IP datagram to determine whether it matches
one of its rules.
Firewall Architecture Models - ANSWER ✓ Used to protect the perimeter of a
network and control the flow of permitted communications.
Intrusion Detection System (IDS) - ANSWER ✓ a computer program that senses
when another computer is attempting to scan or access a computer or network
through intrusion.
