Minimumsecurity

Minimum security is a term used across disciplines to describe the baseline level of protection necessary to reduce risk to an acceptable level. The meaning and requirements vary by context, including corrections, information security, and physical security.

In the criminal justice system, minimum security refers to a designation for facilities housing inmates assessed as low risk of escape or violence. These prisons typically feature dormitory-style housing, limited or no perimeter fencing, fewer guards, and more freedoms for daily activities. Inmates may participate in work programs, education, and supervised movement outside secure areas. Security levels range from minimum to medium and maximum, with classifications adjusted over time based on behavior and risk assessments.

In information security, minimum security often denotes a baseline set of controls that must be in place to protect information systems and data. This baseline may be defined by standards or regulatory frameworks such as NIST SP 800-53 or ISO/IEC 27001, and can include asset inventory, access control, authentication, patch management, configuration management, logging, incident response, and security training. The goal is to reduce common vulnerabilities and provide a foundation for stronger protections, while allowing organizations to tailor the baseline to their risk environment and compliance requirements.

In physical security and risk management, minimum security indicates the least protective measures required for an asset, facility, or operation, determined by factors such as value, threat level, and regulatory obligations. Regular review and updates are recommended to maintain an appropriate balance between security, usability, and cost.
