Frequency Analysis
Frequency Analysis: A method used in cryptanalysis to study the frequency of letters or groups of letters in a ciphertext. The technique is based on the fact that, in any given stretch of written language, certain letters and combinations of letters occur with varying frequencies. If an unauthorized entity conducts frequency analysis successfully, it can […]
Full Backup
Full Backup: The process of copying every file and piece of data from a particular system or storage device. This backup type creates a comprehensive replica of all directories, files, and databases, ensuring that all information can be restored from this single backup if necessary. While full backups can be more resource-intensive than other types […]
Full Disk Encryption (FDE)
Full Disk Encryption (FDE): A security measure used to protect all data on a hard drive. By encrypting every bit of data, including files, folders, and the operating system itself, FDE renders the stored information unreadable to unauthorized individuals. This measure is particularly useful if a device gets lost or stolen, as it prevents unauthorized […]
Functional Testing
Functional Testing: A type of software testing that validates the software system against the functional requirements/specifications. The purpose of functional tests is to test each function of the software application by providing appropriate input and verifying the output against the Functional requirements. This testing mainly involves black box testing and is not concerned about the […]
Fuzzing or Fuzz Testing
Fuzzing or Fuzz Testing: A software testing technique that involves providing invalid, unexpected, or random data as input to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks. A fuzzer is a tool used to carry out fuzz testing. Fuzzing is often automated […]
Flaw
Flaw: A weakness or a defect in a system, be it in a software, hardware component, network design, or business process. This could be a result of coding errors in software, design oversights, or configuration errors. When a flaw is discovered, it often needs to be rectified quickly to prevent exploitation that could compromise system […]
