Network Infrastructure

The Technical University of Košice is considered one of the most advanced university network infrastructures in Slovakia. Since 2009, the high-performance computer network TUNET has been developed and expanded, serving as the backbone of the university’s digital environment, thanks to strategic investments from EU funds.

There is a central data center equipped with powerful routers capable of handling transmission capacities of several terabits per second (Tbps). High availability and reliability are ensured through a backup data center that immediately takes over operations in the event of a failure without any service disruption to users.

Distributed network nodes across university buildings are interconnected by optical links with transmission speeds of up to 100 Gbps. This ensures fast and seamless connectivity for study spaces, offices, IP telephony, and research labs. With more than 11,000 active ports and over 350 professional Cisco switches, the network provides both stability and scalability to support future technological growth.

The TUNET network is connected to the Slovak academic data network, SANET, via a next-generation firewall, providing secure and fast internet access, as well as connectivity with other universities and institutions. Additionally, the university hosts a node of the national peering center SIX (Slovak Internet eXchange), which enhances the speed and stability of data traffic across Slovakia.

At a digital university, where thousands of data requests from teaching, research, and administration are processed daily, cybersecurity is a key pillar of a trustworthy infrastructure. That's why the Technical University of Košice protects its academic network, TUNET, with a cutting-edge solution: the Check Point Next Generation Firewall (NGFW).

This advanced security system offers not only traditional packet-level protection but also intelligent application filtering, intrusion prevention (IPS), advanced identity control, and real-time proactive threat detection. The NGFW also enables transparent rule management, centralized monitoring, and full integration with the academic infrastructure—allowing for rapid incident response without interrupting operations.

With the Check Point Quantum Force 19200 Security Gateway, we are equipped to confront modern threats—from phishing attempts to efforts aimed at compromising research data. Reliable protection for thousands of users, systems, and applications ensures the university can focus on what matters most: education, research, and innovation.

In a modern university environment, flexibility in work and study is essential. Students, teachers, and researchers increasingly need access to university systems outside the campus—from home, labs, international internships, or conferences. To meet these needs, the Technical University of Košice uses Check Point Capsule VPN, a solution that provides secure and encrypted remote access to the TUKE network.

VPN Capsule establishes a secure connection between the user's device and the university infrastructure. This allows seamless and safe access to internal systems, file storage, licensed software, and computing resources—just as if the user were connected directly on campus.

With a focus on data protection, identity verification, and ease of use, Capsule VPN offers a reliable solution that meets the standards of an academic environment. No matter where you are, you remain in control of your access to university resources.

While the university environment is dynamic and open, it also faces a growing number of security threats. Web portals, student systems, online services, and applications all require continuous protection against attacks and misuse. That's why the Technical University of Košice employs F5 Application Security, a state-of-the-art solution that provides an advanced Web Application Firewall (WAF).
