Data Security Policy
Introduction
Institutional data is information that supports the mission and operation of
Tennessee Tech University. It is a vital asset and is owned by the University.
Some institutional data may be distributed across multiple departments or units of
the University, as well as outside entities. Institutional data is considered
essential, and must comply with legal, regulatory, and administrative
requirements.
Departments and units must assess institutional risks and threats to the data
for which they are responsible, and accordingly classify its relative
sensitivity as Level I (low sensitivity), Level II (moderate sensitivity), or
Level III (high sensitivity). Unless otherwise classified, institutional data is
Level II. University personnel may not broaden access to institutional data
without authorization from the department or unit responsible for the data. This
limitation applies to all means of copying, replicating, or otherwise
propagating university data.
All data shares to be set up between systems must be requested via ITS to
ensure data integrity.
Data Classification
Authorization to access institutional data varies according to its
sensitivity (the need for care or caution in handling). For each classification,
several data handling requirements are defined to appropriately safeguard the
information. It’s important to understand that overall sensitivity of
institutional data encompasses not only its confidentiality (need for secrecy),
but also the need for integrity and availability. The need for integrity, or
trustworthiness, of institutional data should be considered and aligned with
institutional risk; that is, what is the impact on the institution should the
data not be trustworthy? Finally, the need for availability relates to the
impact on the institution’s ability to function should the data not be available
for some period of time. There are three classification levels of relative
sensitivity which apply to institutional data:
Level I: Low Sensitivity
Access to Level I institutional data may be granted to any requester, or it is
published with no restrictions. Public data is not considered sensitive. The
integrity of “Public” data should be protected, and the appropriate department
or unit must authorize replication or copying of the data in order to ensure it
remains accurate over time. The impact on the institution should Level I data
not be available is typically low, (inconvenient but not debilitating). Examples
of Level I “Public” data include published “white pages” directory information,
maps, departmental websites, and academic course descriptions.
Level II: Moderate Sensitivity
Access to Level II institutional data must be requested from, and authorized by,
the department or unit who is responsible for the data. Access to internal data
may be authorized to individuals based on job classification or
responsibilities (“role-based” access), and may also be limited by one’s
employing unit or affiliation. Non-Public or Internal data is moderately
sensitive in nature. Often, Level II data is used for making decisions, and
therefore it’s important this information remain timely and accurate. The risk
for negative impact on the institution should this information not be available
when needed is typically moderate. Examples of Level II “Non-Public/Internal”
institutional data include project information, official university records such
as financial reports, human resources information, some research data,
unofficial student records (including grade books without SSNs), and budget information.
Level III: High Sensitivity
Access to Level III institutional data must be controlled from creation to
destruction, and will be granted only to those persons affiliated with the
University who require such access in order to perform their job, or to those
individuals permitted by law. Access to confidential/restricted data must be
individually requested and then authorized by the department or unit who is
responsible for the data. Level III data is highly sensitive and may have
personal privacy considerations, or may be restricted by federal or state law.
In addition, the negative impact on the institution should this data be
incorrect, improperly disclosed, or not available when needed is typically very
high. Examples of Level III “Confidential/Restricted” data include official
student grades and financial aid data; social security and credit card numbers;
individuals’ health information, and human subjects research data that
identifies an individual.
Policy Statement
- Institutional data must be protected from unauthorized modification,
destruction, or disclosure. Permission to access institutional data will be
granted to all eligible University employees for legitimate university
purposes.
- Authorization for access to Level II and Level III institutional data
comes from the department or unit, and is typically made in conjunction with
an acknowledgement or authorization from the requestor’s department head,
supervisor, or other authority.
- Where access to Level II and Level III institutional data has been
authorized, use of such data shall be limited to the purpose for which
access to the data was granted.
- University employees must report instances in which institutional data
is at risk of unauthorized modification, disclosure, or destruction in
accordance with TBR Guideline B-080.
- Departments and units must ensure that all decisions regarding the
collection and use of institutional data are in compliance with the law and
with University policy and procedure.
- Departments and units must ensure that appropriate security practices,
consistent with the data handling requirements in this policy, are used to
protect institutional data.
- Users will respect the confidentiality and privacy of individuals whose
records they access, observe ethical restrictions that apply to the
information they access, and abide by applicable laws and policies with
respect to accessing, using, or disclosing information.
