Cyber Security Academy Instructor
Growing up in China, Jun Dai didn’t own a computer but he was still able to master video games. He got access to computers and the internet through “net bars” that rented machines by the hour. And there, he discovered his passion and a profession, not as a gamer but as a defender.
“Many computers there were infected and behaved abnormally,” Dai recalled, with unexpected websites popping up randomly. He started thinking about online security, how hackers threaten the cyber world and how he would defend against cyber attacks.
Dai is a professor in the Computer Science Department at Sacramento State and among his six courses, a class in computer system attacks and countermeasures. He will bring his expertise to the new Cyber Security Academy, the latest addition to the Summer Academies for High School Students. His academy runs July 24 – 28.
“Cyber security is very important,” Dai says. “Even if you don’t choose this as a career, you still need to know the basics, how to defend yourself online and how to protect your home network.”
Students will see a demonstration of a simulated cyber attack and the increasingly sophisticated methods of hackers, like spoofing an individual’s identity online. Dai will guide students with hands-on labs and show them techniques to protect their computers.
“We never use any techniques as hackers. We only use techniques as defenders,” Dai says, stressing ethics and personal responsibility.
Dai studied computer science in China, earning a bachelor’s degree in information security and a master’s degree in network control. He continued his studies in the U.S. and earned his doctorate from Pennsylvania State University in cyber security. He began teaching at Sacramento State in 2014.
Dai is also the associate director of the Center for Information Assurance and Security within the College of Engineering and Computer Science at the University, which is a designated National Center of Academic Excellence in Information Assurance Education. The center received the designation from the Department of Homeland Security and the National Security Agency.
No doubt, a boyhood of playing video games left a lasting impression for Dai, only the “master battle” against hackers is real. “They are the dark side” of the cyber world, he says, “and we are the bright side.”
