CM-5 Access Restrictions for Change
Description
Any changes to the hardware, software, and/or firmware components of information systems can potentially have significant effects on the overall security of the systems. Therefore, organizations permit only qualified and authorized individuals to access information systems for purposes of initiating changes, including upgrades and modifications. Organizations maintain records of access to ensure that configuration change control is implemented and to support after-the-fact actions should organizations discover any unauthorized changes. Access restrictions for change also include software libraries. Access restrictions include, for example, physical and logical access controls (see AC-3 and PE-3), workflow automation, media libraries, abstract layers (e.g., changes implemented into third-party interfaces rather than directly into information systems), and change windows (e.g., changes occur only during specified times, making unauthorized changes easy to discover)
Applicability
The information resource owner, or designee, is responsible for ensuring that the risk mitigation measures described in this Control are implemented. The intended audience is information resource owners and custodians of university information resources that store or process mission critical and/or confidential information.
Implementation
TAMU-CC defines, documents, approves, and enforces physical and logical access restrictions associated with changes to the information system.
