- Binding In computing, this refers to the creation of a linkage between a software object and a data element, a variable and its value, or a user action and a program response. In the realm of cybersecurity, binding often relates to the secure association of credentials with users or devices to ensure secure authentication processes.
- Biometric Locks Advanced security devices that use unique biological traits, such as fingerprints, eye patterns, or facial recognition, to authenticate and grant access to individuals. Biometric locks enhance security by providing a non-transferable and difficult-to-replicate method for verifying identity.
- Biometrics The science and technology of using biological characteristics, such as fingerprints or facial features, to identify individuals and verify their identity. This concept is used in various fields, including security, healthcare, and finance, to improve accuracy and reduce the risk of identity fraud.
- BIOS (Basic Input/Output System) A low-level software that controls the hardware of a computer and enables it to boot up and perform basic functions. This concept is used in computers to provide a user-friendly interface for accessing and configuring hardware settings, as well as to boot up the operating system. For example, a BIOS might allow a user to change the boot order of devices, or to enable or disable specific hardware components.
- Birthday Attack A type of cryptographic attack that exploits the mathematics behind the birthday problem in probability theory. It takes advantage of the fact that in a set of randomly chosen people, there's a high probability that two of them will share the same birthday. Similarly, in cryptography, the attack uses this principle to find collisions in hash functions, which occur when two different inputs produce the same hash output. This can compromise cryptographic systems that rely on the uniqueness of hash values. The attacker generates multiple variants of input data and computes their hash values until a collision is found. This is significantly faster than a brute force search for two inputs with the same hash value due to the birthday paradox's counterintuitive probability curves. It's particularly a concern for digital signatures and data integrity checks that rely on hashing algorithms.
- Bit error rate the number of incorrect bits transmitted in a message, typically measured as a percentage. It is used in communication systems to measure the reliability of a transmission. For example, a bit error rate of 10^-6 means that out of every 1,000,000 bits transmitted, there will be, on average, one error.
- Bit Splitting A method used in data security and encryption where a single bit of data is divided into two or more separate bits. The split bits are then typically distributed across different storage locations or transmission paths. The purpose of bit splitting is to enhance security, since the original bit is not stored or transmitted whole, it becomes more difficult for unauthorized parties to intercept and piece together the complete data.
- Black Box Testing A method of evaluating system functionality without any knowledge of its internal workings or structure. This approach views the system as a "black box," focusing solely on input and output without concerning itself with internal behavior. It can be applied in various scenarios, including functional testing, integration testing, and system testing. In a security context, it is used in penetration testing to identify vulnerabilities or potential entry points for attacks, mimicking the approach of a potential external attacker.
- Blind FTP A form of FTP where the server allows file transfers without requiring the user to log in with credentials. Typically, such servers are configured to permit anonymous access, often used for distributing files that are meant to be publicly available.
- Blind Test in Penetration TestingThe pentest method in which security professionals simulate an actual attack on a system, with limited information provided about the target beforehand. This approach is designed to mimic the real-world tactics and techniques of potential attackers, who typically have no inside information. It allows organizations to get a realistic understanding of their security vulnerabilities and how well their detection and response mechanisms perform under such conditions.
