What is a key principle in maintaining the security of CJIS data?

The choice highlighting the importance of not sharing access credentials underscores a fundamental principle in maintaining the security of Criminal Justice Information Services (CJIS) data. Access credentials serve as the keys to sensitive information; when shared, they can lead to unauthorized access and potential misuse of confidential data. Each user is granted specific access based on their role, and sharing these credentials compromises the accountability and traceability of actions taken within the system.

When individuals do not share their credentials, it reinforces security protocols that prevent unauthorized individuals from accessing critical information that could affect law enforcement operations and the safety of the public. This principle is vital for safeguarding public and sensitive data managed by law enforcement agencies.

The other options, while they may have relevance in broader security contexts, do not address the immediate and critical aspect of securing access to data. Public awareness campaigns, system downtime, and restrictions on user training are not as direct or impactful in protecting CJIS data integrity and confidentiality as the practice of keeping access credentials secure.
