1 PURPOSE
The purpose of this policy is to ensure the secure use and handling of all district data, computer systems and computer equipment by District students, patrons, and employees.
2 POLICY
2.1 Technology Security
It is the policy of Walden School of Liberal Arts (hereafter Walden) to support secure network systems in the district, including security for all personally identifiable information that is stored on paper or stored digitally on district-maintained computers and networks. This policy supports efforts to mitigate threats that may cause harm to the district, its students, or its employees.
The district will ensure reasonable efforts will be made to maintain network security. Data loss can be caused by human error, hardware malfunction, natural disaster, security breach, etc., and may not be preventable.
All persons who are granted access to the district network and other technology resources are expected to be careful and aware of suspicious communications and unauthorized use of district devices and the network. When an employee or other user becomes aware of suspicious activity, he/she is to immediately contact the district’s Information Security Officer with the relevant information.
This policy and procedure also covers third party vendors/contractors that contain or have access to Walden’s critically sensitive data. All third party entities will be required to sign the Restriction on Use of Confidential Information Agreement before accessing our systems or receiving information.
It is the policy of Walden to fully conform with all federal and state privacy and data governance laws. Including the Family Educational Rights and privacy Act, 20 U.S. Code §1232g and 34 CFR Part 99 (hereinafter “FERPA”), the Government Records and Management Act U.C.A. §62G-2 (hereinafter “GRAMA”), U.C.A. §53A-1-1401 et seq and Utah Administrative Code R277-487.
Professional development for staff and students regarding the importance of network security and best practices are included in the procedures. The procedures associated with this policy are consistent with guidelines provided by cyber security professionals worldwide and in accordance with Utah Education Network and the Utah State Office of Education. Walden supports the development, implementation and ongoing improvements for a robust security system of hardware and software that is designed to protect Walden’s data, users, and electronic assets.
