- Balanced Scorecard (BSC) A strategic planning and management system used to align business activities with the vision and strategy of the organization. Within the realm of risk management, it can help organizations monitor performance against strategic goals, considering perspectives like financial performance, customer knowledge, internal business processes, and learning and growth. This tool is particularly effective in maintaining a comprehensive view of system health, offering valuable insights that can be used for proactive security management and threat mitigation.
- Bandwidth The maximum rate of data transfer across a given path or network connection, typically measured in bits per second (bps). The term is used to denote the capacity of a connection to handle data traffic, affecting the speed and quality of data transfer. High bandwidth is particularly important for the transmission of large volumes of data or for applications with real-time communication needs, such as video conferencing or online gaming.
- Banner A message displayed on a computer screen or network device that identifies the system and provides information about the system's capabilities and limitations. It is commonly used to provide a warning or disclaimer to users before they access a system or network. Examples include the login banner on a server or the banner displayed by a firewall before allowing access to a network.
- Banner Grabbing A technique used to gather information about computer systems on a network by sending requests and analyzing the responses (the banners) that contain details about the services running on the system. It is often an initial step in network reconnaissance for both legitimate purposes, such as network inventory, and malicious intents, like vulnerability assessment for exploitation.
- Bar code A series of parallel lines or bars of varying widths that represent data in a machine-readable format. It is commonly used to identify and track products, documents, or other objects in a variety of industries, including retail, healthcare, and logistics. Examples include the barcodes found on retail products, patient identification wristbands in hospitals, and shipping labels for packages.
- Baseband The original frequency range of a signal before it is modulated for transmission. In data communication, baseband transmission allows digital signals to be sent directly over the medium without modulation into higher frequency ranges. This type of transmission is common in wired local area networks, where the entire bandwidth of the cable is used for a single signal or multiple signals in a time-division multiplexing manner.
- Base Case The simplest instance or the starting point in a series of scenarios, typically used as a benchmark in the context of scenario analysis or problem-solving. For instance, in testing a new security feature, the base case could represent the system's behavior without the new feature being implemented. By examining the base case, one can understand how deviations from this base scenario (like introducing new features or changes) affect the system's performance or security.
- Baseline A reference point or standard against which the performance or status of a system or process can be measured. It is commonly used in project management, quality control, and performance monitoring to establish a baseline for comparison and to identify deviations or improvements. Examples of baselines in IT include the baseline configuration of a server or network device, the baseline performance of a system or application, and the baseline security posture of an organization.
- Baseline Architecture The current state of an architectural framework within an organization, including the interplay of technology, processes, and people. It provides a comprehensive view of how different components of a system interact, from hardware to applications to data flows. This architecture serves as the reference point for planning future changes, identifying gaps, or analyzing potential impacts of modifications. Its understanding is crucial in maintaining system stability and security, ensuring changes don't introduce new vulnerabilities or disrupt existing safeguards.
- Baseline Reporting The process of documenting the standard state or performance level of a system, typically done for comparative analysis over time. In a security context, this can be valuable for identifying abnormalities or potential threats, as significant deviations from the established baseline may indicate an issue. Such reports could include information on normal network traffic patterns, typical user behavior, and system performance metrics, among others.
