Stanford has classified its information assets into risk based categories for the purpose of determining who is allowed to access the information and what security precautions must be taken to protect it against unauthorized access.
As of May 2015, a new set of classifications has been established and is now in effect for Stanford data and systems: Low Risk, Moderate Risk, and High Risk. The former framework - Prohibited, Restricted, Confidential, and Unrestricted - will be phased out by January 2016.
Special note to Stanford researchers: Except for regulated data such as protected health information (PHI), Social Security Numbers, and financial account numbers, research data and systems predominately fall into the Low Risk classification. Review the classification definitions and examples below to determine the appropriate risk level to apply.
Low Risk
Data and systems are classified as Low Risk if they are not considered to be Moderate or High Risk, and:
- The data is intended for public disclosure, or
- The loss of confidentiality, integrity, or availability of the data or system would have no adverse impact on our mission, safety, finances or reputation.
Moderate Risk
Data and systems are classified as Moderate Risk if they are not considered to be High Risk, and:
- The data is not generally available to the public, or
- The loss of confidentiality, integrity, or availability of the data or system could have a mildly adverse impact on our mission, safety, finances or reputation.
High Risk
Data and systems are classified as High Risk if:
- Protection of the data is required by law/regulation,
- Stanford is required to self-report to the government and/or provide notice to the individual if the data is inappropriately accessed, or
- The loss of confidentiality, integrity, or availability of the data or system could have a significant adverse impact on our mission, safety, finances or reputation.
Data Risk Classification Examples
Use the examples below to determine which risk classification is appropriate for a particular type of data. When mixed data falls into multiple risk categories, use the highest risk classification across all.
