Ransomware risk: Malicious actors can target encrypted data in ransomware attacks, holding it hostage until a ransom is paid. Common Encryption Algorithms Several encryption algorithms exist for different circumstances. The most common algorithms are: Data Encryption Standard (DES): An original and less...
Reused passwords: The same password is used to log in to different websites so that hackers can use the password of a single account to obtain the access permissions of all the user's accounts. Cleartext passwords: During password storage and transmission, cleartext passwords are not encrypted,...
In cryptography, an encryption key is a variable value that is applied using analgorithmto a string or block of unencrypted text to produce encrypted text or to decrypt encrypted text. The length of the key is a factor in considering how difficult it will be to decrypt the text in a given...
it is converted into a format that is unreadable without the corresponding decryption key. This means even if someone gained unauthorized access to the device, they would not be able to view the encrypted data without the key, thereby providing an additional layer of security for sensitive informa...
Column-level encryption is an approach to database encryption in which the information in every cell in a particular column has the same password for access, reading and writing purposes. Deniable encryption is a type of cryptography that enables encrypted data to be decrypted in two or more way...
A plaintext password is a password that is not encrypted using an encryption algorithm, rather than the password displayed on the screen when you enter it through the keyboard. For example, when you configure the authentication password of a SNMPv3 USM user, the system prompts you to enter th...
Caesar encrypted his messages by changing the order of the alphabetical letters. In order to decrypt the message, the intended recipient would have to substitute the written letter for the corresponding letter in the original message to decode the encrypted message. This is called a substitution cip...
What Are a Plaintext Password and a Ciphertext Password A plaintext password is a password that is not encrypted using an encryption algorithm, rather than the password displayed on the screen when you enter it through the keyboard. For example, when you configure the authentication password of...
What is Hypertext Transfer Protocol Secure (HTTPS)? Hypertext Transfer Protocol Secure (HTTPS) is an extension of Hypertext Transfer Protocol (HTTP). It is used to securely transfer data over a network. In HTTPS, the communication is encrypted using TLS. HTTPS provides authenticated of the accesse...
million credit cards. Although the credit card information was encrypted, the hackers’ sophistication still broke through the encryption and is regarded as one of the largest breaches of its kind in U.S. history, leading to an investigation by the U.S. Secret Service and the Justice ...
