RS-232 interface
RS-232 interface: A serial communication standard used to connect devices, such as computers and terminals. It is used to transmit data between devices, typically at slow speeds. Examples include a serial cable used to connect a computer to a modem or a serial port used to connect a terminal to a mainframe.
Scalability in cloud computing
Scalability in cloud computing: The ability to handle an increased workload without a decrease in performance. This concept is used in cloud computing to ensure that a system can handle the added demand of new users or applications without slowing down. For example, a company might need to add new users to its cloud-based email […]
Risk-based access control
Risk-based access control: A dynamic method of controlling access to resources based on the risk associated with a user’s access at any given time. This approach considers factors such as the value of the resources being accessed, the current security state of the system, and the identity or role of the user in making access […]
RSA (Rivest-Shamir-Adleman)
RSA (Rivest-Shamir-Adleman): A widely accepted public key cryptosystem developed by Ron Rivest, Adi Shamir, and Leonard Adleman. It enables secure data transmission and is commonly used for securing sensitive data, particularly when sent over an insecure network. RSA’s security comes from the computational difficulty of factoring large composite integers, which is the product of two […]
Scavenging
Scavenging: The practice of searching for and reusing discarded or abandoned data, often involving combing through discarded hardware devices, network traffic, or public domains for residual data. Unprotected data or insufficiently sanitized storage media can be exploited, emphasizing the need for robust data disposal practices and secure data transmission to prevent unauthorized access.
Rivest Cipher 4 (RC4)
Rivest Cipher 4 (RC4): A stream cipher that was widely used in various protocols, most notably in WEP for wireless network security and in early versions of SSL/TLS for securing web traffic. However, due to vulnerabilities that have been discovered over time, RC4 is no longer considered secure and has been largely replaced by more […]
