Policy information: IT-12 System and Communications Protection (SC) Standard
About This Standard
Status: Effective July 9, 2024
Responsible University Office: University Information Policy Office
Responsible University Administrator: Office of the Vice President for Information Technology and Chief Information Officer
Policy Contact: University Information Security Office uiso@iu.edu
Scope
This standard supports Policy IT-12 (Security of Information Technology Resources) and applies to all Indiana University information technology resources, regardless of whether those resources are managed by the university or provisioned from third parties on behalf of the university, and to all users of those resources regardless of affiliation.
Objectives
The key objectives of this standard are to ensure that:
- Organizational communications (i.e., information transmitted or received by organizational information systems) are monitored, controlled, and protected at the external boundaries and at key internal boundaries of the information systems; and
- Architectural designs, software development techniques, and systems engineering principles are employed to promote effective information security within organizational information systems.
Standard
The following tables detail baseline security controls for awareness and training that are to be applied to a particular information technology resource based on its security categorization. Select controls as applicable. For example, all controls may not apply to every system component or technology, or to situations governed by specific regulations.
Control: | Denial of Service Protection | ||
Required for: | High | Moderate | |
IU Implementation | Implement safeguards to mitigate the risk of Denial of Service (DoS) attacks. | ||
Notes | Use of centrally provisioned, common IT infrastructure and services provided by UITS often fulfills many of these requirements. Check with the service owner for details. | ||
NIST Cross Reference | SC-5 | ||
Control: | Boundary Protection | ||
Required for: | High | Moderate | |
IU Implementation | Control network communications at internal and external boundaries. Implement as many of the following as practicable:
| ||
Notes | Use of centrally provisioned, common IT infrastructure and services provided by UITS often fulfills many of these requirements. Check with the service owner for details. | ||
NIST Cross Reference | SC-7 | ||
Control: | Transmission Confidentiality and Integrity | ||
Required for: | High | Moderate | |
IU Implementation |
| ||
Notes |
| ||
NIST Cross Reference | SC-8 | ||
Control: | Cryptographic Key Establishment and Management | ||
Required for: | High | Moderate | Low |
IU Implementation | Manage encryption keys to keep them secure:
| ||
Notes | Do not use a self-made encryption algorithm. See also Passphrase vaulting and About data encryption. Use of centrally provisioned, common IT infrastructure and services provided by UITS often fulfills many of these requirements. Check with the service owner for details. | ||
NIST Cross Reference | SC-12 | ||
Control: | Protection of Information at Rest | ||
Required for: | High | ||
IU Implementation | Encrypt Critical and Restricted data at rest.
| ||
Notes |
| ||
NIST Cross Reference | SC-28 | ||
Definitions
Standard – Standards (like procedures) support policy by further describing specific implementation details (i.e., the "how"). A standard can be thought of as an extension of policy that articulates the rules, mechanisms, technical or procedural requirements, or specifications to be used in carrying out/complying with policy. Standards, along with procedures, promote a consistent approach to following policy. Standards make policies more practically meaningful and effective. Standards are definitional and clarifying in nature, specifying the minimums necessary to meet policy objectives. Because standards directly support policies, compliance with standards is nonoptional and failure to follow standards may result in sanctions imposed by the appropriate university office.
Sanctions
Indiana University will handle reports of misuse and abuse of information and information technology resources in accordance with existing policies and procedures issued by appropriate authorities. Depending on the individual and circumstances involved, this could include the Office of Human Resources, Vice Provost or Vice Chancellor of Faculties (or campus equivalent), Dean of Students (or campus equivalent), Office of the Vice President and General Counsel, and/or appropriate law enforcement agencies. See Policy IT-02 (Misuse and Abuse of Information Technology Resources) for more details.
Failure to comply with Indiana University information technology policies may result in sanctions relating to the individual's use of information technology resources (such as suspension or termination of access, or removal of online material); the individual's employment (up to and including immediate termination of employment in accordance with applicable university policy); the individual's studies within the university (such as student discipline in accordance with applicable university policy); civil or criminal liability; or any combination of these.
