Symmetric Encryption - Answer-Type of cryptography. secret-key, shared-key-private
key.) uses same key for encryption and decryption.
DES - Answer-Symmetric Algo. Data Encryption Standard - the archetypal block cipher.
Designed to encipher and decipher blocks of data consisting of 64 bits under control of
a 56bit key. (8bit parity); fixed block
3DES - Answer-Symmetric Algo. Triple repeated process for added strength until orgs
can afford AES. 168bit keys (56bitx3)
AES - Answer-Symmetric Algo. Advanced Encryption Standard is a symmetric key
algorithm used by US gov to secure sensitive but unclassified material. Iterated block
cipher, works by repeating the same operation multiple times. Replaced DES. It has a
128-bit block size with key sizes of 129, 192, and 256.
IDEA - Answer-Symmetric Algo. International Data Encryption Algorithm. Block Cipher.
Operates similar to DES (operates on 64bit blocks using 128bit key). Used with PGP
Twofish - Answer-Symmetric Algo. Block cipher key size greater than or equal to 256bit
Threefish - Answer-Symmetric Algo. Large tweakable symmetric key block cipher. Block
and key sizes are equal (256, 512, 1024)
Blowfish - Answer-Symmetric Algo. Rep by AES, 64bit block
RC4 - Answer-A variable key size symmetric key stream cipher used in WPA and WEP.
RC5 - Answer-RC5, is a fast block cipher. a parameterized algorithm with variable block
sizes, variable key size, and variable number of rounds. key size is 128 bits
RC6 - Answer-A symmetric key block cipher derived from RC5 with integer
multiplication, for 4-bit working registers)
, asymmetric encryption - Answer-uses two keys (public and private) created as a
matched pair.
ECC - Answer-Asymmetric Algo. Elliptical Curve Cryptography. Low process
power/mobile
El Gamal - Answer-Asymmetric Algo. !=Primes, log problem to encrypt/sign
RSA - Answer-Public Key crypto system for internet encryption and authentication. 2
very large Prime #s, 4,096bit. Modern std for asymmetric encryption.
MD5 - Answer-Hash Algo. 128bit hash, express as 32bit hex
SHA1: - Answer-Hash Algo. 160bit has, rq 4 use in US apps
Web of trust - Answer-Entities sign certs for each other
Single authority - Answer-CA at top. Trust based on CA itself
Hierarchical - Answer-CA at top. RA's Under to manage certs
XMKS - Answer-XML PKI System
5 phases to a penetration test/hacking phases - Answer-Recon
Scanning & Enumeration
Gaining Access
Maintaining Access
Covering Tracks
Attack types - Answer-OS: Attacks targeting default OS Settings
App Level: Application code attacks
Shrink Wrap: off the shelf scripts and code
Misconfiguration: not configured well
RFC 1918 - Answer-Private IP Standard
RFC 3227 - Answer-collecting and storing data
ISO 27002 - Answer-InfoSec Guidelines
CAN-SPAM - Answer-email marketing
