Correlation
Correlation: The relationship between two or more variables, such as the relationship between a security incident and a potential vulnerability. It is used in security analysis to identify patterns and connections between different data sets. Examples include using correlation to link network traffic to a specific user or to identify a trend in phishing attacks.
Counter (CTR) Mode
Counter (CTR) Mode: An encryption mode that transforms a block cipher into a stream cipher. It operates by encrypting successive values of a “counter” and then XORing the output with the plaintext to produce the ciphertext. The counter value is incremented for each subsequent block, ensuring a unique sequence for each encryption. This mode allows […]
Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP)
Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP): A security protocol used in wireless networks to encrypt data and ensure its authenticity. It is a combination of the AES encryption algorithm and the CCM mode of operation, which provides both confidentiality and integrity for data transmitted over a wireless network.
Coupling
Coupling: In the context of software design, coupling refers to the degree to which one module or component depends on another. High coupling indicates that a change in one module may require changes in other modules, while low coupling allows for a more modular and independent design.
Covert Channel Analysis
Covert Channel Analysis: The process of examining systems to identify and mitigate covert channels. This process involves reviewing system design and operations to uncover unintended communication paths that could be exploited for unauthorized information transfer. It’s a crucial component of comprehensive security audits and assessments, particularly in high-security environments.
Covert Channel
Covert Channel: A communication channel that enables information transfer in a way that violates security policies, typically by using mechanisms that were not originally intended for communication. This can include using system properties or resources (like processor usage or file modification times) to covertly transmit information, enabling entities to communicate surreptitiously without detection.
