"We have checkpoints now on campus, increased communication with law enforcement," Sacks said. "We increased the number of emergency drills we do. We revamped our emergency communication plan and crisis communication plan and all that."

Sacks said the school has hired an extra security officer, expanded and upgraded its 911 notification capabilities, created stricter campus visitor policies, and implemented a workplace violence prevention policy.

On campus, the school has installed a digital patrol check system for 24-hour security patrols. And it's completed a cyber re-keying project, limiting access to the building without first being approved.
