Information security is a critical aspect of the rapid development of information technology in government agencies. The Directorate General of Corrections has been continuously improving its information security due to its highly confidential system's data, which includes the data of inmates and their relatives. This study aims to measure the level of employee information security awareness at the Indonesian Correctional Institution. The importance of each focus area was adopted from the KAMI Index and the HAIS-Q was measured by using the Analytical Hierarchy Process (AHP). A total of 87 valid questionnaire questions were distributed to 218 employees at the Directorate General of Corrections and the Correctional Unit. The questionnaire was processed by using descriptive statistics. The results showed that employee awareness regarding information security was satisfactory, with a value of 85.81%. This study also provides some recommendations to maintain and improve information security awareness.
