Configuration errors occur when settings in a system or application are incorrectly set, leading to unintended behavior or failures. These errors can arise from human mistakes, such as entering the wrong values, or from software bugs that misinterpret the intended configuration. Common examples of configuration errors include incorrect network settings, which can prevent devices from communicating, or misconfigured security settings that leave systems vulnerable to attacks. Addressing these errors often requires careful review and testing of the configuration files or settings to ensure they align with the desired operational standards.
