Data Classification Standard


All university data must be classified into one of the four categories described in this standard and protected using appropriate security measures consistent with the minimum standards for the classification level as described in related information/data security policies.

The Standard

This standard serves as a supplement to the Data Access and Security Policy. Adherence to the standard will facilitate applying the appropriate security controls to university data.

The objective of this standard is to assist data owners, data access managers, and data custodians in determining the level of security required to protect data on the systems for which they are responsible. The standard divides data into four categories:

Data Classification

Institutional Risk from Disclosure



Category I: Regulated Private Data



Regulated data whose unauthorized access or loss could seriously or adversely affect UB, a partner, or the public. Security breaches of these data are subject to the NY State Information Security and Breach Notification Act and other federal, state, and industry rules and regulations.

Category II: Protected Data


Regulated data subject to FERPA or other federal, state, or business regulation; any data specifically exempt from release/disclosure to the public by state or federal statue.  This includes data exempt from disclosure in NY State‚Äôs Freedom of Information Law (FOIL).  FOIL exempts data that if disclosed would constitute an unwarranted invasion of personal privacy.

  • FERPA-protected data
  • Gramm Leach Bliley data and other data protected by law or regulation
  • Final Course Grades, Exam Questions or Answers

Category IV: Public Data

This standard exists in addition to all other university policies and federal and state regulations governing the protection of the university’s data. Compliance with this classification standard will not ensure that data will be properly secured. Instead, this standard should be integrated into a comprehensive information security plan.

All university data stored on university resources or other resources where university business occurs must be classified into one of the four categories. Based on the data classification, data owners, trustees, custodians, and users are required to implement appropriate technical security measures to protect the data consistent with the university Minimum Security Standards for protecting the data. Category-I data has more stringent requirements than Categories II, III, and IV. All systems require some protective measures.

Note: Data that is personal to the operator of a system and stored on a university IT resource as a result of incidental personal use is not considered university data. University data stored on non-university IT resources must still be verifiably protected according to the respective university minimum security standards.

Applicability and Scope

This policy applies to all members of the University at Buffalo community, as well as to external vendors and contractors.


Category I: Regulated Private Data

Regulated private data is defined using the definition of private information in the New York State Security and Breach Notification Act of 2005 as a foundation: bank account/credit card/debit card numbers, Social Security Numbers, state-issued drivers’ license numbers, and state-issued non-drivers’ identification numbers. To this list UB policy adds protected health information (PHI), computer passwords and other computer access protection data, and passport numbers. Note that Category I data are exempt from disclosure/release under the NY State Freedom of Information Law (FOIL). The Breach Notification Act requires that the university must disclose any breach of the data to NY residents. (State entities must also notify non-residents, see Information Security Policy P03-002 V3.3 Part 12) - pdf.)

Category II Protected Data

Includes University data not identified as Category-I data, but data protected by state and federal regulations. This includes FERPA-protected student records and electronic records that are specifically exempted from disclosure by the NY State Freedom of Information Law (FOIL).  

Such data must be appropriately protected to ensure that they are not disclosed in a FOIL request. FOIL excludes data that if disclosed would constitute an unwarranted invasion of personal privacy. Specific details on FOIL-excluded data are provided in the Appendix.

Category III Internal Use Data

Includes University non-public data not included in Category I (regulated private data) or Category II (protected data); Internal Use data includes Person Number, licensed software, as well as university business records, intellectual property, and any non-public data that is releasable in accordance with FOIL.

Category IV Public Data

General access data, such as that available on unauthenticated portions of; Category IV data have no requirement for confidentiality.
