What Steps Can K–12 IT Teams Take in the Face of Increasing Cyberattacks?

Ransomware and phishing attacks are too common in today’s learning environment. Here’s how schools can keep bad actors out now and in the future.

School districts are facing increased cybersecurity risks, continuing a trend we’ve seen over the past few years, which was exacerbated by last year’s shift to online learning. The large-scale increase in network and technology use allowed bad actors new opportunities, which they quickly seized with phishing attacks and other attempts to exploit new vulnerabilities.

K–12 Education Faces Growing Cybersecurity Concerns

Across sectors, 2021 has been a banner year for ransomware. FortiGuard Labs found that average weekly ransomware activity in June 2021 was 10 times higher than activity in the same month one year earlier. Attacks devastated the supply chains of multiple organizations — particularly in sectors of critical importance — and impacted daily life, productivity and commerce more than ever before. High-profile incidents have even led the federal government to take action, launching a joint task force specifically devoted to combatting ransomware.

In looking at IPS detections, FortiGuard Labs researchers also found that education saw higher levels of activity regardless of the exploit in question. This continues a trend from 2020, which saw a record-setting 408 publicly disclosed cybersecurity incidents in the K–12 sector, according to The State of K-12 Cybersecurity: 2020 Year in Review, published by the K-12 Cybersecurity Resource Center. The attacks affected 377 school districts in 40 states and cost millions of dollars to remediate.

Thankfully, although the risks are real and growing, there are ways to combat these attacks. The shift to remote learning left many districts and schools vulnerable as the threat landscape became larger and more complicated. But district IT teams don’t need to feel alone in this situation.

How Can Schools Prepare for Cyberattacks Now?

For schools already grappling with numerous challenges related to the pandemic, many IT systems likely remain underfunded. But cybersecurity isn’t something that can be ignored.

Prevention is always key, and users are the first and best line of defense. It’s important to implement security awareness training as an immediate first step. All faculty and staff members should be able to spot phishing emails and know not to click on dangerous links.

Anti-spam and anti-malware capabilities are another preventive security to combat phishing. Software-defined WAN will also play a major role in both evolving and securing networks as the edge expands. Real-time endpoint protection, detection, and automated response solutions will be vital to secure environments along with a zero-trust approach to access.

Network firewalls are another important security component, combined with network segmentation to separate internet-facing applications from back-office applications. Web application firewalls should be placed in front of learning management systems and anything else that’s externally facing.

In addition, make sure to create, test and maintain a cybersecurity incident response plan that outlines the steps to take during incidents such as a ransomware attack.

How Can Schools Prepare for Future Cybersecurity Threats?

As school districts around the country enter a new school year already fraught with pandemic concerns, cyber risks are ever present. Even with classes taking place in person, the danger still exists. In response, the U.S. Senate recently passed the K-12 Cybersecurity Act, which would direct the Cybersecurity and Infrastructure Security Agency to conduct a comprehensive study of the cybersecurity risks schools face and develop recommendations and resources for schools.

Bad actors also know that schools are chronically underfunded and their IT departments are frequently understaffed. Not to mention that these teams are often working with legacy systems and heterogenous infrastructure.

These factors don’t mean the education sector is helpless. Educating network users, implementing key technologies and putting an incident response plan in place will all help to defend schools against cyberthreats today and into the future.
