After a series of Zoom "bombings" across the district and state, Leander ISD is upgrading its technology with greater security control settings and added security layers.

The district started improvements Sept. 11 and will add more security enhancements in the coming weeks, according to a district release. LISD is piloting the requirement of district account authentication.

"Our goal is to ensure the safest and most secure learning environment where our kids can focus on learning and will not be exposed to content that is not intended for young minds," said the district in the release. "We recommend that families discuss the importance of staying safe online and look forward to partnering with our families and community in this endeavor."

Technology upgrades include attendance tracking, additional instructional tools such as polls and premade breakout groups, instructors' use of additional authentication, students' inability to start meetings, varying access based on groups and enhanced support from Zoom.

The total number of Zoom incidents is unknown, LISD spokesperson Matt Mitchell said. Larger incidents, including the Zoom bombing at River Ridge Elementary School, are more reported, but smaller, less horrific incidents may go unreported to the district.
