1. Introductory provisions

These operating regulations define the rules for using the Technical University of Liberec's computer network (hereinafter, the “network”). The aim is to ensure secure, efficient and responsible access to the university’s network and computing resources.

2. Scope of application

These rules apply to all network users – students, employees, guests, partners, and other authorized persons.

3. Terminology

The network infrastructure consists of cabling, wireless frequencies, and active components (switches, routers, Wi-Fi access points, etc.), as well as all other connected devices (computers, servers, disk arrays, computer classrooms, uninterruptible power supplies, and more).

A network user (the "user") is a person who uses the network's infrastructure and/or central services.

The network administrator (the "Administrator") is the Information Systems Department at the Rector's Office. You can contact the Administrator at net@tul.cz, through the Helpdesk system, or through other information systems operated by the Administrator.

4. Access to the network

Any employee, student, guest, or supplier of the Technical University of Liberec (TUL) can become a user.

Account creation

User accounts are created automatically when a person is added to the employee or student registry. For guests and suppliers, accounts are created upon request submitted to the Administrator. The account is provided to:

1. TUL employees for the duration of their employment relationship (longer than three months).
2. TUL students for the duration of their studies. The account is typically set up for one academic year and automatically renewed if the student enrolls for the next academic year and is listed in IS/STAG.
3. TUL guests, based on a justified request submitted by a TUL employee; guest accounts are always limited to the shortest necessary time period.
4. Suppliers on the basis of a contractual relationship, to the extent necessary for contract performance.

Account termination

A user account on the network is terminated:

1. at the user's request,
2. for employees upon termination of employment at TUL; in the case of retirement, the email address may be retained and redirected at the employee’s request,
3. for students upon completion of studies; for 30 days thereafter, access to email, IS/STAG, and cloud storage is retained,
4. for guests upon expiration of the account validity period,
5. for suppliers upon termination of the contractual relationship,
6. in the case of a serious violation of these operating rules.
