Business-to-business (B2B): B2B refers to the exchange of products, services, or information between businesses, rather than between businesses and consumers. Cybersecurity in B2B transactions is crucial to protect trade secrets, customer data, and maintain the integrity of business operations.

Business-to-consumer E-commerce (B2C): The online sale of products or services by businesses directly to consumers. This process often involves financial transactions and the exchange of personal data, making the implementation of robust security measures crucial to protect the consumers' personal and financial information and to maintain the trust and reputation of the businesses involved.

Bus topology: A network design where each computer and network device are connected to a single cable or backbone. In this topology, information sent from a device moves in both directions along the backbone until it reaches its destination device. If the backbone fails, the entire network becomes unusable, highlighting the importance of regular checks and maintenance in these setups. Despite this drawback, bus topology is appreciated for its simplicity and cost-effectiveness, especially for small networks.

BYOD (Bring Your Own Device): A corporate policy allowing employees to use their personal electronic devices for work-related tasks. This approach can increase flexibility and employee satisfaction but also introduces security implications. Personal devices may not have the same stringent security controls as company-issued hardware, potentially exposing the network to malware or data breaches. To mitigate risks, businesses often implement BYOD security policies that include the use of VPNs, mandatory antivirus software, regular security updates, and the compartmentalization of company data through containerization or secure applications. These measures aim to safeguard sensitive information while accommodating the convenience of using personal devices.

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.
