In your area, do you trust that local schools are prepared to handle major cyberattacks?

A report from the Center for Internet Security, MS-ISAC, and CoSN highlights that 51% of surveyed K-12 schools experienced a cyber incident during the recent school year. These incidents frequently disrupt essential classroom instruction, student information systems, and payroll operations.

Why it matters

Schools rely on digital networks for critical infrastructure, including security cameras, smart locks, and bus scheduling systems. When these systems are compromised, it threatens both the operational continuity of schools and the safety of the campus environment.

Approximately 83% of schools have implemented multi-factor authentication and email security protections. Additionally, the MS-ISAC protective DNS web security service successfully blocked 3.1 million potential cyber threats throughout the school year.

The players

Center for Internet Security

The Center for Internet Security is a non-profit organization focused on enhancing the cybersecurity readiness and response of public and private sector entities.

MS-ISAC

The Multi-State Information Sharing and Analysis Center serves as a key resource for the United States to protect state, local, tribal, and territorial governments from cyber threats.

CoSN

The Consortium for School Networking is a professional association for school system technology leaders that provides resources to support digital learning.

The details

Nearly 34% of schools reported that these digital attacks directly impacted daily operations. While 33% of organizations have adopted formal AI policies, 80% of respondents stated they still require additional resources and expert guidance to bolster their defenses.

Timeline

  1. The 2025-2026 school year saw 11,600 cyber incidents requiring escalation and response.

  2. The report was officially released on October 27, 2026.

  3. A webinar hosted by CIS and MS-ISAC is scheduled for November 4, 2026.

The Tech Race

The reliance on the MS-ISAC protective DNS web security service highlights a systemic defense strategy that schools must adopt to combat evolving digital threats. This marks a transition from reactive recovery methods to proactive network security as the primary industry standard.

Parents and staff may experience disruptions to school communications, payroll systems, and digital learning platforms due to these escalating network attacks. Schools are increasingly adopting multi-factor authentication to secure student data, requiring users to adapt to new login procedures.

The takeaway

Schools must prioritize the integration of formal security policies to protect both operational infrastructure and student information. Administrators should leverage available resources like protective DNS services to mitigate the high volume of threats targeting the education sector.

What happens next

A webinar hosted by CIS and MS-ISAC will take place on November 4, 2026, to discuss the report findings and provide further guidance.
