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 […]
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 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, […]
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 Execution Prevention (DEP)
Data Execution Prevention (DEP): A security feature included in most modern operating systems. Its primary function is to help prevent damage to your system from viruses and other security threats by monitoring programs to ensure they use system memory safely. When DEP detects a program using memory incorrectly, it closes the program and notifies the […]
Cryptosystem
Cryptosystem: A suite of cryptographic algorithms and protocols designed to secure communication and data by providing confidentiality, data integrity, authentication, and non-repudiation. A cryptosystem facilitates secure data storage and transmission in various IT applications.
