REST (Representational State Transfer)
REST (Representational State Transfer): An architectural style for designing networked applications. It uses a stateless, client-server communication model, where each message contains all the information necessary to understand and process the request. REST is often used in web services development due to its simplicity, scalability, and performance. The principles of REST encourage the use of […]
Remote rekeying
Remote rekeying: The practice of updating cryptographic keys on a remote device or system. It is used in secure network environments where encryption is utilized to maintain the security of the encrypted data. Remote rekeying is performed periodically or under specific circumstances, such as when a key is compromised, to ensure the continued security and […]
Restricted interface
Restricted interface: A security principle that advocates for limiting the exposure of the working of a system. It involves providing only the necessary features and functionalities needed to fulfill specific tasks, thereby reducing the attack surface and limiting the potential for misuse. By restricting the functionality and information available, the scope for errors or security […]
Remote Terminal Units (RTUs)
Remote Terminal Units (RTUs): Devices deployed in the field that interface with sensors or other equipment to collect real-time data, typically in industrial control systems like SCADA. They serve as a focal point for monitoring and controlling physical processes, converting sensor signals into digital data that can be sent to a central system or controller […]
Restrictive defaults
Restrictive defaults: A security principle that advocates for configuring systems with the most secure settings by default. This approach limits access and permissions to the minimum necessary, requiring explicit granting of additional access by users or administrators to ensure security and prevent unintended access or breaches.
Renewal
Renewal: The process of extending the validity of something, such as a digital certificate or subscription to a security service. This is an important process that ensures continued protection and access to service. Failure to renew may lead to a lapse in service, possibly leaving systems unprotected or causing service disruptions.
