Channel Service Unit/Digital Service Unit (CSU/DSU)

Channel Service Unit/Digital Service Unit (CSU/DSU): Hardware devices used in digital telecommunications to connect the end customer’s equipment with the public switched network. A CSU/DSU translates the digital signals produced by the customer’s equipment into signals that can be transmitted over the carrier’s network and vice versa. These devices are essential for enabling reliable data […]

Cell-level Encryption (CLE)

Cell-level Encryption (CLE): A database encryption method that encrypts individual cells, or fields, within a database table, allowing for fine-grained control over access to sensitive data. Each cell can be encrypted with a unique key, which prevents unauthorized users from reading the data while still allowing the database to perform complex queries, as the database […]

Channels

Channels: In a communication context, channels refer to the medium through which data is transmitted from one place to another. This could include physical channels, such as wires or fiber optic cables, and wireless channels, such as those used in radio or infrared communication. From a security perspective, protecting these channels is essential to ensure […]

Cache-timing Attack

Cache-timing Attack: A side-channel attack that exploits the timing information of a system’s cache to gain insights into the data and operations processed by the system. Attackers measure the time it takes to perform certain operations to make inferences about the data, such as cryptographic keys, in the cache. These attacks are sophisticated and rely […]

Cellular networks

Cellular networks: A type of wireless communication network that uses radio frequencies to transmit data between mobile devices and the network operator’s network infrastructure. Cellular networks are commonly used in smartphones and other mobile devices to provide access to the Internet, phone calls, and other services. Examples of cellular networks include GSM, LTE, and 5G […]

Chaos engineering

Chaos engineering: A method of testing the resilience and robustness of systems by intentionally introducing failures or disruptions into a system in a controlled manner. It is used to identify and address potential weaknesses or vulnerabilities in a system and to ensure that it can withstand unexpected failures or events. Examples of chaos engineering include […]
