Computer-Aided Software Engineering (CASE): The use of computer-based tools to support the development, testing, and maintenance of software. It is used to automate and streamline the software development process and to improve the quality and reliability of software. Examples of CASE tools include modeling tools, code generation tools, and testing tools.

Computer-Assisted Audit Technique (CAAT): A set of tools and techniques used by auditors to analyze an organization's data with software, improving efficiency and accuracy in audit processes. CAATs include data extraction and analysis tools, which can automate procedures to identify anomalies or patterns in data related to financial statements or compliance.

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 for random access to encrypted data blocks and can provide high levels of security when implemented correctly. Additionally, CTR mode allows for parallel processing of blocks, which enhances performance.

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.

Cable lock: A physical security tool designed to prevent theft of devices. Typically, it is a cable that is securely attached to an immovable object at one end and a device (like a laptop) at the other end. While not a direct deterrent for advanced attacks, cable locks can help prevent opportunistic theft and tampering, enhancing the overall security posture of an environment.

Cable modem: A type of network bridge that allows bi-directional data communication via radio frequency channels on a hybrid fiber-coaxial and radio frequency over glass infrastructure. Cable modems are primarily used to deliver broadband Internet access, leveraging the high bandwidth of a HFC and RFoG network.
