This project can be used as a resource to easily create customized security baselines of technical security controls by leveraging a library of atomic actions which are mapped to the compliance requirements defined in NIST SP 800-53 (Rev. 5). It can also be used to develop customized guidance to meet the particular cybersecurity needs of any organization.
The objective of this effort was to simplify and radically accelerate the process of producing up-to-date macOS security guidance that is also accessible to any organization and tailorable to meet each organization’s specific security needs.
Any and all risk based decisions to tailor the content produced by this project in order to meet the needs of a specific organization shall be approved by the responsible Information System Owner (ISO) and Authorizing Official (AO) and formally documented in their System Security Plan (SSP). While the project attempts to provide settings to meet compliance requirements, it is recommended that each rule be reviewed by your organization's Information System Security Officer (ISSO) prior to implementation.
