Rogers was replaced as the banquet speaker by Maj. Gen. Kimberly Crider, mobilization assistant to the commander of Air Force Space Command. She will be part of a panel that also includes Erin Miller, vice president of operations for the Space Information Sharing and Analysis Center, an affiliate of symposium host the National Cybersecurity Center. The panel is expected to discuss threats in space and whether U.S. satellites are vulnerable to cyberattacks.

John Chen, executive chairman and CEO of BlackBerry, follows Rogers on the agenda and is expected to discuss the company’s move from its popular mobile devices to software and cybersecurity, largely through acquisitions. A native of Hong Kong while the city was still under British control, he has served on many councils and committees related to U.S.-China trade and relations.

The symposium also will feature multiple breakout sessions on election security, education and training, workforce development, artificial intelligence and the growth of internet-connected devices.

The second day will include the Mayor’s Cyber Cup, a competition among students to create public service announcements about cyberbullying, safe social media and online practices and cybersecurity for children. The creator of the winning announcement will receive a free iPad.
