Cybersecurity in Education: A Growing Concern

Introduction

Education is often referred to as an "industry of industries," encompassing a vast array of data types, including health records, financial information, and other sensitive data. Educational institutions, from K-12 schools to universities, are increasingly becoming prime targets for cybercriminals. With an average of 2,507 cyberattack attempts per week, the education sector faces unique challenges that require robust cybersecurity measures. This article explores the current cybersecurity landscape in education, the threats faced, and strategies for defending against these attacks.

Security Snapshot

The education sector is characterized by a diverse user base, including students, faculty, and administrative staff, all of whom interact with various digital platforms and devices. This environment creates a fertile ground for cyber threats. Many educational institutions struggle with limited IT resources, often operating a mix of modern and legacy systems. In the U.S., personal devices are frequently used in educational settings, leading to a lack of security awareness among users. The result is a complex cybersecurity landscape where vulnerabilities are abundant, and the stakes are high.

Threat Briefing

A Uniquely Valuable and Vulnerable Environment

The education sector’s openness and collaborative culture make it particularly susceptible to cyber threats. With users ranging from young students to seasoned professionals, the potential for exploitation is significant. Cybercriminals are increasingly targeting educational institutions, with the sector being the third-most attacked industry globally. In the U.K., 43% of higher education institutions reported experiencing a cyberattack at least weekly, underscoring the urgency of the situation.

QR Codes: A New Vector for Phishing Attacks

The rise of quick response (QR) codes in educational settings has introduced new risks. These codes are often embedded in emails and flyers, making them an attractive target for phishing attacks. The U.S. Federal Trade Commission has issued alerts about the dangers of malicious QR codes, which can lead to stolen credentials or malware infections. Microsoft Defender for Office 365 reports that over 15,000 malicious QR code messages target the education sector daily, highlighting the need for vigilance.

Email Systems: A Breeding Ground for Compromise

Many educational institutions maintain open email systems to facilitate communication. However, this openness can lead to vulnerabilities, as cybercriminals exploit weak email hygiene to launch attacks. The combination of high email traffic and limited controls creates an environment ripe for compromise.

Nation-State Actors: Targeting Valuable Intellectual Property

Nation-state actors are increasingly targeting educational institutions for espionage. Universities often conduct sensitive research and collaborate with government agencies, making them attractive targets for cyber espionage. Cybercriminals may compromise lower-level targets within educational institutions to gain access to higher-value targets in government or industry.

Defending Against Attacks

Building a New Security Curriculum

Addressing cybersecurity in education requires more than just technology solutions; it necessitates a cultural shift. Educational institutions must prioritize cybersecurity awareness among students, faculty, and staff. Implementing core cyber hygiene practices, such as strong password policies and multifactor authentication, can significantly reduce the risk of attacks.

Case Studies: Successful Security Implementations

Oregon State University (OSU) faced a significant cybersecurity incident in 2021, prompting the establishment of a Security Operations Center (SOC). This center has become central to OSU’s security efforts, leveraging AI to enhance threat detection and response.

Arizona Department of Education has taken a proactive approach by blocking all traffic from outside the U.S. in its Microsoft 365 environment. This stringent policy helps protect sensitive data and systems from external threats.

Recommendations for Educational Institutions

1. Educate and Train: Regularly train students and staff on cybersecurity best practices, emphasizing the importance of vigilance against phishing attacks and QR code scams.

2. Implement Strong Security Measures: Utilize protective domain name services to block harmful websites and enforce strict password policies with multifactor authentication.

3. Centralize Security Operations: Streamline technology stacks to improve monitoring and response capabilities, allowing for a clearer picture of the institution’s security posture.
