1. CIA Triad (Confidentiality, Integrity, Availability) The three principles of security control and
management: confidentiality integrity and availability. Also known as the informa-
tion security triad or triple.
2. Parkerian Hexad A model that adds three more principles to the CIA triad: possession or control,
utility, and authenticity
3. Interception At- Allow unauthorized users to access our data, applications, or environments, and
tacks are primarily an attack against confidentiality.
4. Interruption An attack that causes our assets to become unusable or unavailable for our use,
AAsttack on a temporary or permanent basis
-primarily affects availability
-can affect integrity
5. Modification At- An attack that involves tampering with our assets
tack -primarily affects integrity
-can affect availability
6. Fabrication At- An attack that involves generating data, processes, communications, or other
tack similar activities with a system;
- affects primarily integrity and availability
7. Authentication verifying the identity of the person or device attempting to access the system
8. Least Privilege a principle that users be granted the privilege for some activity only if there is a
justifiable need to grant this authorization
9. Access Control Determines types of user access, such as read-only access
10. Symmetric En- An encryption method whereby the same key is used to encode and to decode the
cryption message

asymmetric en- two keys are used; one key encodes the message, and the other key decodes the
cryption message
12. Symmetric Key DES, 3DES, AES
Algorithms
13. Symmetric Key Uses three different ciphers: one with a 128-bit key, one with a 192-bit key, and
Algorithms: AES one with a 256-bit key, all having a block length of 128 bits
14. Symmetric Key DES used to encrypt each block three times, each with a different key
Algorithms: 3DES
15. Symmetric Key A block cipher based on symmetric key cryptography and uses a 56-bit key. Not
Algorithms: DES that secured any more.
16. Symmetric Cryp- Encryption that uses a single key to encrypt and decrypt a message.
tography
17. Asymmetric-Key SSL, to secure transactions like web and e-mail traffic
Algorithm:
Secure Sockets
Layer (RSA)
18. Asymmetric-Key can secure all browser connections to the Web servers
Algorithm:
Elliptic Curve
Cryptography
19. Asymmetric-Key securing messages and files
Algorithm: Pretty
Good Privacy
(PGP)
