Schools (public and nonpublic) and school districts face a myriad of challenging hazards and threats. In addition to natural hazards, technological hazards, and biological hazards, they now have to prepare for human-caused cyber threats. These incidents can be accidental or deliberate and disrupt education and critical operations; expose sensitive personally identifiable information (PII) of students, teachers, and staff; and lead to high recovery costs. This fact sheet focuses on addressing threats to a school's or school district's network and systems also called "cybersecurity" considerations.
