  • Report, at least annually, to the institution of higher education head or his or her designated representative(s) the status and effectiveness of information resources security controls.
  • Issue exceptions to information security requirements or controls in this chapter. Any such exceptions shall be justified, documented, and communicated as part of the risk assessment process.
  • Work with the owners of information resources to develop strategies to meet their required responsibilities and to ensure compliance.

Information Owner Responsibilities – the owner or their designated representative(s) are responsible for and authorized to:

  • Approve access and formally assign custody of an information resources asset
  • Determine the asset's value

  • Confirm that controls are in place to ensure confidentiality, integrity, and availability of data and other assigned information resources.
  • Assign custody of information resources assets and provide appropriate authority to implement security controls and procedures
  • Review access lists based on documented security risk management decisions
  • Approve, justify, document and be accountable for exceptions to security controls. The information owner shall coordinate exceptions to security controls with the ISO or other person(s) designated by the state institution of higher education head.

Custodians of information resources shall:

High Risk

Medium Risk

Low Risk

Involve large dollar amounts, or significantly important information that would impact the operations of the HSC, or

Involve a moderate or low dollar value, or

Generally available public information, or

Contain confidential or sensitive data, or

Information that could potentially create problems for the parties involved, or

Managing Security Risks

A security risk analysis of information resources shall be performed and documented on the following schedule:

  • Annually on information resources classified as high risk
  • Biennially on information resources classified as medium or low risk

Security risk assessment results, vulnerability reports and other security analysis information shall be presented to the President of the HSC or their designated representative(s).  The President of the HSC or designated representative(s) shall make the final security risk management decisions to either accept the risks or to modify the security and controls for the information resources based on its value and sensitivity.  The President of the HSC or their designated representative(s) must approve the final security risk management plan.
