Cryptography
Cryptography: The science and practice of secure communication in the presence of third parties called adversaries. It involves creating written or generated codes that allow information to be kept secret. Cryptography encompasses various techniques such as encryption (scrambling data so it’s unreadable without a key), decryption (making the scrambled data readable again with the correct […]
Data Discovery Methods
Data Discovery Methods: Data Discovery Methods refer to a range of processes and tools used to identify, classify, and analyze an organization’s data assets. They are crucial for data governance, risk management, and compliance, ensuring that sensitive data is properly handled and protected. Techniques include automated discovery using software to scan storage systems and databases, […]
Cryptology
Cryptology: The study of codes and ciphers, which encompasses both cryptography (creating codes and ciphers to keep information secure) and cryptanalysis (breaking them to access the information). Cryptology is a branch of mathematics and computer science that deals with the principles and techniques of translating readable data into secure forms and vice versa. It’s fundamental […]
Data Emanation
Data Emanation: The unintentional radiation or transmission of electrical signals from electronic equipment, such as a computer or a network device, which can potentially disclose sensitive information. Adversaries can intercept and decode these signals, also known as compromising emanations, to gain unauthorized access to the information, making mitigation techniques such as shielding, signal jamming, or […]
Cryptoprocessor
Cryptoprocessor: A dedicated microprocessor designed specifically to handle cryptographic operations, such as creating digital signatures and managing keys securely. These processors are often embedded in hardware devices and provide an extra layer of security, protecting sensitive data even if the system’s main processor is compromised. They are often found in applications requiring high levels of […]
Data Encryption Standard (DES)
Data Encryption Standard (DES): A symmetric-key algorithm for encrypting electronic data. Developed in the 1970s and once widely used, DES encrypts data in 64-bit blocks using a 56-bit key. It was eventually found to be vulnerable to brute-force attacks and has been largely replaced by more secure standards like the Advanced Encryption Standard (AES). However, […]
