Network security: Protects against unauthorized access attempts, malware, and viruses. It also protects network infrastructure from attacks. Cryptography: Secures communication over a network and protects data's confidentiality, integrity, and authentication. It uses keys to encrypt and decrypt data. Viruses: Malicious, downloadable files that can replicate themselves by changing other computer programs with their own code. They can corrupt or destroy network data, or spread from one computer to another. Ransomware: A type of malware that encrypts a user's data and demands a ransom for...

Viruses: Malicious, downloadable files that can replicate themselves by changing other computer programs with their own code. They can corrupt or destroy network data, or spread from one computer to another. Ransomware: A type of malware that encrypts a user's data and demands a ransom for access. Ransomware uses asymmetric encryption, which uses a pair of keys to encrypt and decrypt a file. Encryption: Often made irreversible so that the original password cannot be deciphered from the encrypted one. When the password is entered for authentication, it is encrypted and compared with the stored one. If a match occurs, the authentication becomes valid. Salting: A cryptographic technique used in hashing to enhance and make them unreadable. A random salt string can be placed on either side of any password to change its hash string. Show less
