If logging in IT systems is incorrectly configured, important information will be missed or not recorded properly. It is also possible that incorrect or excessive information will be logged. For example, personal data may be logged and stored without authorisation. The organisation in question could thus be in violation of related legal requirements.

Due to incorrectly configured logging, log data may also be available in inconsistent or proprietary formats. In such cases, logs may be difficult to assess and security incidents may remain undetected.
