Galileo processors used in cybersecurity classrooms


The fight against cyber attacks and hacking rages on. In response, the North East Independent School District of San Antonio, Texas (NEISD) has opened a novel new cybersecurity training facility, the Institute of CyberSecurity and Innovation (iCSI). iCSI trains students to detect and identify hacks and cyberattacks and respond to threats.

Students at all seven North East ISD high schools have access to networking and cybersecurity courses. Students progress through a four-year path in which they have the opportunity to earn professional certifications in information technology. The curriculum provides students with hands-on learning opportunities and hands-on practice related to the job skills that employers are looking for.

iCSI has two cybersecurity classrooms designed with the look and feel of a security operations center. Each classroom contains three video walls powered by RGB Spectrum’s Galileo video display processors. A single Galileo processor in each classroom controls the three video walls: two consist of 2×4 arrays of 55-inch LCDs and a larger 2×6.

RGB Spectrum’s Galileo processor was selected for its real-time performance, ability to support a wide variety of digital and IP-based signal sources, and exceptional 4K picture quality.

At iCSI, students learn how to set up, configure and secure computer systems and networks in a data center specially designed for this purpose. Students can provision hundreds of virtual machines and private networks. You will be challenged daily to study the most important cybersecurity concepts.

The Galileo processors receive an extensive range of baseband and IP-based inputs: classroom PCs, Open Broadcast Software (OBS) virtual machines driving live RTSP streaming feeds, internet traffic analysis, cyber attack alerts, threat intelligence, local and national Web resources, newscasts and social media channels.

Content on display includes monitoring dark web transactions, hacking community chatter, and maps depicting simulated cyber security attack origin and destination points. The processors consolidate key visualizations and data to provide students with a centralized, correlated view.

Source signals are displayed in windows of any size anywhere on the video wall. Teachers can instantly switch and route sources, select preset display layouts, and pan and zoom to view specific items of interest.

Josh Beck, Senior iCSI Instructor, stated, “The RGB Spectrum Galileo meets our training goals very well. This display technology has become key to the teaching process. It’s great to have displays of sufficient resolution and size so that all students can easily see all relevant information. As we work through step-by-step procedures it is very easy for all students to see what the instructor is doing and use it as a reference point.”

Beck continues: “It looks great and makes a great impression on guests and visitors. It is very flexible and allows instructors to get creative with lessons and challenges. Overall it’s great. “

RGB Spectrum’s CAT Linx 2 HDBaseT extenders were installed to transmit the visual data from the Galileo processor to the video wall monitors. CAT-Linx 2 extenders transmit signals at up to 4K resolution over conventional CAT 5e/6 cables up to 330 feet in length. For easy and convenient installation, these extenders have built-in PoH power delivery to power endpoints over the same CAT5e/6 cable carrying the video and data signals. This eliminates the need for external power connections. A CAT-Linx 2 pair only requires one power supply connected to either the transmitter or receiver end to power both devices. The extender’s advanced features include HDCP 2.2, Dolby and DTS HD audio support, and serial and IR control of display devices.
