provide additional security along with normal authentication.

(a)  

is the science of secret communication where the aim is to transfer the information over an insecure channel in such a way that no third party can understand what is being conveyed.

(a)  

vulnerability: a weakness in any information system component.

(a)  

is the process of securing and managing passwords throughout their life cycle from creation to closure by adhering to a set of sustainable practices.

(a)  

also known as privileged password management is an integral part of any organization's IT security management and is focused on protecting the credentials of corporate accounts that hold elevated access privileges.

(a)  

one of the most common methods hackers use to steal admin login credentials.

(a)  

provides a simple method to expand the key size of DES (by applying DES algorithm thrice to each data block), without the need to develop a completely new block cipher algorithm.

(a)  

Uses different keys for encryption and decryption.

(a)  

Uses the same key for both encryption and decryption.

(a)  

is the successor of DES and trusted as the standard by the United States government and various organizations.

(a)  

is basically the maintenance of system integrity, availability, and confidentiality.

(a)  

security violation or attack that can happen any time because of a security vulnerability.

(a)  

a known security gap left open.

(a)  

an asymmetric key encryption technique and a standard for encrypting data sent over the Internet.

(a)  

is a public key cryptography technique followed shortly after RSA.Also known as Exponential Key Exchange,

(a)  

is asymmetric key cryptography based on the Diffie-Hellman Key Exchange. Its security depends on the difficulty of computing discrete logs in a large prime modulus.

(a)  

identifying each user of the system and associating the executing programs with those users.

(a)  

is a symmetric key encryption method that uses 128-bit block size and key size up to 256 bits.

(a)  

works with a 64-bit block length and a variable key size, ranging between 32 bits to 448 bits.

(a)  

described as the life of a computer system. It's the primary software component that is loaded into the system which allows the system to become operational and controllable.
