Anomaly-based monitoring - correct answer Also known as statistical anomaly based;
establishes a performance baseline based on a set of normal network traffic
evaluations.
Signature-based monitoring - correct answer Frames and packets of network traffic are
analyzed for predetermined attack patterns. These attack patterns are known as
signatures.
Behavior-based monitoring - correct answer A monitoring system that looks at the
previous behavior of applications, executables, and/or the operating system and
compares that to current activity on the system.
Simple Network Management Protocol (SNMP) - correct answer A TCP/IP protocol that
monitors network-attached devices and computers. It's usually incorporated as part of a
network management system. Application layer protocol UDP port 161/162
Cipher - correct answer An algorithm used to encrypt and decrypt text.
Cryptography - correct answer The study and use of techniques for securing
communication or hiding information
Algorithms - correct answer Well defined instructions that describe computations from
their initial state to their final state
Steganography - correct answer the art and science of hiding information by
embedding messages within other, seemingly harmless messages. It is a form of
security through obscurity
, Advanced Encryption Standard (AES) - correct answer A symmetric key encryption
standard, used with WPA and WPA2, that is the successor to DES/3DES and is
composed of three different block ciphers: 128, 192, 256
Blowfish - correct answer A 64-bit block cipher designed by Bruce Schneier as an
alternative to DES
Twofish - correct answer A 128-bit block cipher designed by Bruce Schneier and based

encrypting and decrypting e-mail messages, that does not use patented algorithms.
Pseudorandom number generator (PRNG) - correct answer Used by cryptographic
applications that require unpredictable output. Example: SHA2 PRNG. Threat: random
number generator attack. Prevention: additional randomness, AES, SHA256 or higher
and physical control of the system
Pass the hash - correct answer An attack where the password hashes are obtained
from a server and reused in an attempt to trick the server's authentication system
Birthday attack - correct answer An attack on a hashing system that attempts to send
two different messages with the same hash function, causing a collision
