Question

Explain des in computer network security

Answer 1

DES key length and brute-force attacks. The Data Encryption Standard is a block cipher, meaning a cryptographic key and algorithm are applied to a block of data simultaneously rather than one bit at a time. ... Hence, it would take a maximum of 2^56, or 72,057,594,037,927,936, attempts to find the correct key.

Answer 2

Computer security:

Computer security is a branch of computer technology, known as coin coin and information security implemented in the network. The purpose of computer security is to protect information and content from theft, corruption or natural disaster while keeping information and content accessible to its intended users.

Computer system security means the publication of sensitive and important information and services by collective processes and mechanisms, from tampering or unauthorized activities or unrelated persons and unplanned events, respectively.

Computer security strategies and practices often differ from most other computer technologies because its hidden purpose is to prevent unwanted computer behavior rather than to enable the desired computer behavior.
