Its monitoring systems, cameras, and doors all stopped working. The facility shut down for 30 hours. The source of the attack? An employee had opened an e-mail and clicked the link inside, which contained malware, a type of software designed to damage computer networks.

There, students learn the basics of programming using Python, the coding language favored by many hackers. In one activity, students investigate a crime scene — a computer where intentionally harmful code was used. Physical clues lead them to a Twitter account. And they must decrypt(解密) a message posted to the account. “Cybersecurity is not a fixed thing,” Baggili says. “Every day, you’re going to be facing different kinds of problems.
