Kuinka suojata peruskoulupiiriäsi kyberhyökkäyksiltä

Cyberattacks on K-12 schools are rising and every district, regardless of size or location, needs a plan. This guide covers the most common threats and the strategies your team can deploy today to protect your students, staff, and data.

For years, cyberattacks have been a source of concern for K-12 schools, and studies show, they’re rising. 

Districts need to do more to protect their school networks and their data.

Cyberattacks against K-12 schools are rising for multiple reasons:

  • Many district IT departments are overtaxed and underfunded
  • BYOD is increasing (both on and off-campus)
  • Districts have a wealth of personal data (both student and staff)
  • Districts frequently use new software

Simply put, school districts are viewed as easy targets by cybercriminals.

Once cybercriminals compromise your data, not only are your students at risk but also teachers, staff, and administrators whose personal data has also been stored within district networks.

Cyberattacks can also prevent you from contacting your staff in an emergency, from paying your staff or other service providers, and from retrieving students’ coursework or your district’s data and financial records.

As such, it should not be solely up to your IT department to protect your district from cyberattacks. It is up to you and your district leaders to work closely with your colleagues in IT to ensure cybersecurity is given the time and resources required to secure your district. This guide will cover strategies all districts—regardless of size or location—can deploy to help mitigate the risk of cyberattacks.

In this section, we will examine the most common ways districts are targeted by cybercriminals and what you can do to mitigate that risk.

The human factor

Breaches in cybersecurity most often occur because of human error. While this could be caused by careless behavior, it is more likely the person has a poor understanding of cybersecurity as a process.

What can your district do?

Regular cybersecurity training is your best defense against human error. Educate your students and staff about the dangers of security breaches, the typical threats, and the ways to protect against them.

Next, make password protection part of your district's culture by:

Additionally, it is always better to restrict access to all important data and to blacklist websites that are unnecessary for education. Your district’s web filter can help with this.

You can also consider software that resets passwords and restricts access to prevent data breaches tai monitors student engagement and privacy to help mitigate student data privacy vulnerabilities.

While phishing scams used to be easy to spot, the scams continue to evolve to better target savvier internet users.

What can your district do?

One of the most effective ways to avoid phishing scams is to adequately train staff and teachers to recognize the signs of fraudulent communications.

Let them know they should look out for:

Regularly remind your district—whether through weekly cybersecurity newsletters, in-service days, or a combination—to err on the side of caution.

Let them know they should look out for:

Finally, a good spam filter can help block phishing emails and is a critical backup to cybersecurity education and awareness campaigns.

Today, most districts have blogs, websites, and social media pages. But if anyone can comment on your post or page, they can also spam your page’s comments section or insert potentially harmful links in those comments.

What your district can do:

To prevent this vulnerability, your district needs to manage its online pages with intention, deeper understanding, and cautiousness. One way to do this is to use spam filters for comments on your blog and website. This will help block any malicious link injection in your comments section.

Your district’s web filter can play a part in keeping your students and your district safe on social media. Software like Lightspeed Filter™ gives admins control over social media access and the ability to set policies by group, age, grade, or user to ensure the right users have the right access.

Malware is one of the most common and dangerous types of cyberattacks because it can be hard to spot quickly.

What your district can do:

Personal devices, malicious links or websites, and outdated software can all serve as entry points for malware. Ensure you have strong firewalls at the network and application levels to help stop malware from infiltrating your district’s network. Additionally, your web filter can be an effective tool. For instance, Lightspeed Filter™ offers security features that help categorize and block malware.

Next, create a malware playbook with the steps you will take if a malware attack occurs. Be sure to include a contact list with your insurance carrier and even the local FBI contact. Your malware playbook should also address your communication plan. For instance, who will need to be notified and what information should you share? It is important to test your playbook, so run a gameday around it.

In the case of a successful malware attack, seek immediate professional help. Malware can be very serious and fighting it requires a strong understanding of cybersecurity and security systems. The solution here is not to deal with it individually unless you are a professional.

Usually used to siphon credit card information and other financial data, formjacking may be a particular threat to private and parochial schools that require parents to make payments online.

What your district can do:

Most formjacking attacks occur via third-party software and the code is put in long before that software is installed on the user’s network. Districts can combat this by consistently testing new updates and running vulnerability tests.

Using a masked credit card or paying via Apple Pay®, Google Pay™, or another online payment system that employs tokenization can also offer parents and staff extra protection when they enter financial data into a school’s website.

Schools are responsible for vast amounts of data about their students and employees. This wealth of information makes them a prime target for data breaches.

What your district can do:

According to a report by Kindergarten Through Twelfth Grade Security Information Exchange (K12 SIX), the most common access point for data breaches at schools is through third-party vendors and administrative services. Lax agreements with third-party vendors can leave confidential information exposed to unauthorized users or lead to physical data misappropriation. To mitigate risk, school districts need to ensure the partners and vendors they work with use up-to-date, comprehensive security features.

A Distributed Denial of Service (DDoS) attack overwhelms a target like a website with a flood of malicious internet traffic from multiple sources. This “denies” service to real users, making the system unusable. While DDoS attacks can increase at the start of the school year, they are not the primary threat to K-12 districts, accounting for only 1% of attacks.

What your district can do:

Robust firewalls can help identify incoming attacks, notify administrators, and block the damage. To mitigate the fallout if a DDoS attack does get through, create backup sites and systems that can handle redirected web traffic. Known as network redundancy, this tactic can ensure that districts keep running if their primary systems go down.

Cloudflare is a possible solution as well, depending on your district’s website. If your district’s website is hosted in a cloud provider, the provider likely already offers some protection.

Funds and government agencies recommend similar tactics. For instance, the U.S. Department of Education’s Privacy Technical Assistance Center (PTAC) advises districts to take the following steps to establish cybersecurity:

TASB Risk Management Fund, which provides risk management solutions to Texas school districts and other educational entities, recommends designating an information security officer (ISO) who, when possible, has information security duties as their primary role. This person would have the explicit authority to administer data privacy and cybersecurity requirements on behalf of your district’s board, superintendent, or other relevant executive-level management. The ISO would be tasked with developing and maintaining a cybersecurity plan that includes appropriate information security policies, procedures, and technical controls. Additionally, the officer should provide guidance and assistance to board members, information owners, information custodians, and end-users concerning their independent responsibilities in combating cyber risk.

These are some of the ways to protect your district from cyberattacks. In the next section, we provide a list of other resources your district can leverage to help protect itself.

There are many online resources available that provide additional guidance to school districts looking to develop cybersecurity plans.
