Misconfiguration

A **misconfiguration** refers to a state in which a system, device, or software is set up with incorrect or inappropriate settings, parameters, or options. This can lead to a variety of undesirable consequences, including security vulnerabilities, performance issues, instability, data loss, and overall system malfunction. These errors often stem from human error during setup, lack of proper documentation, insufficient understanding of system requirements, or a failure to keep up with system updates and security best practices. Detection and remediation of misconfigurations are critical for maintaining system integrity and functionality.
