Cybersecurity Best Practices for Higher Education

Introduction

The increasing scale and sophistication of cyber threats have made cybersecurity a centerpiece of every higher education institution’s risk management strategy. As technology becomes increasingly foundational to both in-person and online learning, institutions need to invest in regular upgrades to their technology to keep pace with external cyberattacks. Higher education institutions manage vast amounts of sensitive data, including student records, financial information, and intellectual property. Implementing effective cybersecurity measures is essential to protect this data from cyber threats. As universities move more data to the cloud, such as to cloud enterprise resource planning systems, cybersecurity concerns are growing due to the rising frequency of attacks. To protect this critical data, universities must implement robust cybersecurity measures.

The Growing Threat Landscape in Higher Education

Higher education institutions have become hotspots for cyber threats. With an ever-expanding digital footprint, universities and colleges face unique cybersecurity challenges, such as protecting student information and groundbreaking research. In 2023, the average cost of a data breach in higher education soared to $3.65 million - a massive blow to institutions’ finances and reputations.

Educational institutions faced an average of 2,507 attempts per college or university per week in the first quarter of 2023 alone, marking a 15 percent rise compared to the previous year. With a 44 percent increase in cyberattacks since 2022, the education sector ranked as the least secure industry sector.

Data breaches can result in substantial financial losses. Cyberattacks disrupt the normal operations of educational institutions. Denial-of-service (DoS) attacks can render online learning platforms inaccessible, causing significant disruptions to students' education. Ransomware attacks encrypt critical data, leading to an operational standstill until the ransom is paid or the data is recovered. The reputational damage caused by data breaches and cyber incidents is immeasurable and hard to recover from, as these breaches compromise an institution's image and erode trust among students, parents, graduates, donors, and partners.

Why Higher Education Is Vulnerable

Universities and colleges are increasingly finding themselves in the crosshairs of cybercriminals. This vulnerability stems from several unique characteristics:

The Wealth of Sensitive Data: Universities and colleges handle large volumes of sensitive data, including personal information, financial records, intellectual property and research data. This makes them attractive targets for cybercriminals looking to exploit such information for identity theft, financial fraud or competitive advantage.
Extensive and Diverse User Base: Educational institutions’ extensive and diverse user base includes current students and staff and alumni. Enforcing stringent cybersecurity measures across such a broad user base, with varying levels of tech-savviness and security awareness, can be overwhelming.
Open and Collaborative Nature: Higher education thrives on openness and collaboration. While these values are indispensable to academic progress, they can pose significant cybersecurity risks. The open nature of these networks, which facilitates information sharing and connectivity, can also make it easier for attackers to find and exploit vulnerabilities.
Limited Resources for Cybersecurity: Despite their critical need for robust cybersecurity, many higher education institutions, especially public ones, face significant budget constraints. This often results in underfunded cybersecurity initiatives, insufficient cybersecurity infrastructure, and a shortage of specialized personnel. Such constraints leave institutions more at risk than well-resourced corporate environments. Without budget availability, it's more difficult for educational institutions to fortify their infrastructures against the increasing and evolving threat landscape or compete with commercial businesses to recruit skilled IT talent.
Legacy Systems: Many higher education institutions were early adopters of internet technology. And although significant upgrades have been made, reliance on outdated legacy systems is not uncommon.

Common Cyber Threats Facing Higher Education

As cyber threats continue to evolve, colleges and universities must navigate the many risks that can compromise their operations, reputations and the privacy of their communities. Here are some of the most significant cybersecurity risks that higher education institutions are currently facing:

Data Breaches: Data breaches occur when unauthorized individuals gain access to confidential information. For universities and colleges, this could mean exposing personal student records, financial information, employee data and sensitive research materials. The aftermath of a data breach can be disastrous, affecting the trust of students, faculty and stakeholders. It could lead to identity theft, financial fraud and the loss of intellectual property.
SQL Injections: Educational institutions rely heavily on databases to manage student records, grades, administrative details and more. However, if a hacker successfully executes an SQL injection attack, they can bypass security measures and gain unauthorized access to this treasure trove of information. SQL injection occurs when a malicious actor takes advantage of vulnerabilities in an application's code that interacts with a database. This violates user privacy and tarnishes the integrity of the institution. Grades could be tampered with, personal information exposed and trust shattered.Instead of entering legitimate data in the user input fields, the hacker inserts malicious SQL commands crafted to exploit vulnerabilities in the application's user input handling. The application fails to validate or sanitize the user input properly, so the malicious SQL commands are not filtered out and are passed directly to the database server for execution. The database server, unaware that the SQL commands are malicious, executes them as legitimate queries. This allows the attacker to perform actions such as extracting sensitive data, modifying database contents, or gaining administrative access to the system.
Phishing: Phishing attacks involve tricking individuals into revealing sensitive information or downloading malware by posing as a trustworthy entity in electronic communications. In the context of higher education, attackers might impersonate administrators, IT staff or even fellow students to obtain passwords, banking details or access to institutional networks. Phishing remains one of the most common attack vectors due to its simplicity and effectiveness, particularly in environments with a wide range of tech proficiencies. The cyber security breaches survey published by the UK government in 2024 uncovered that higher education institutions are particularly vulnerable to phishing attacks, with 100% of surveyed institutions experiencing at least one in the past 12 months.
Ransomware: Ransomware attacks involve hackers encrypting an institution’s data and demanding payment for the decryption key. These attacks can cripple essential systems, from administrative databases to digital learning platforms, as demonstrated by the closure of Lincoln College. These attacks do not typically result in data theft but can hinder critical digital services, impede learning, disrupt administrative tasks and damage the institution's reputation for reliability.
Insider Threats: Insiders know the most about the inner workings of their institution, and most have access to at least one or more systems with personal data. Complicating things further, many data breaches caused by insiders are unintentional.

Cybersecurity Best Practices for Higher Education Institutions

The higher education cybersecurity landscape is fraught with challenges, but these challenges are not insurmountable. Educational institutions must take proactive measures to protect their data and students by implementing strong security policies, access controls, and anti-malware solutions and fostering a culture of cybersecurity awareness and education.

Here are some best practices that higher education institutions can implement to mitigate cyberattacks:

Implement Strong Security Controls and Guidelines: The first step to establishing a robust security policy is implementing strong security controls and guidelines for handling sensitive data.
Access Control: Access control is essential for limiting unauthorized access to sensitive data. Educational institutions should adhere to the principle of least privilege and ensure that individuals only have access to the necessary programs and data for their roles. Institutions should also look into improving authentication, implementing centralized identity, managing third-party access, reducing the use of easy-to-hack passwords, and adding multi-factor or biometric authentication.
Multi-Factor Authentication (MFA): Adopting multi-factor authentication (MFA) and encryption technologies is vital for protecting sensitive information. MFA adds a security layer by requiring two or more verification factors, significantly decreasing the risk of unauthorized access. One of the most important cybersecurity measures for higher education is multi-factor authentication (MFA). MFA adds an extra layer of protection by requiring users to verify their identity using multiple forms of authentication, such as passwords, biometrics, or one-time codes. Did you know that 63% of data breaches in higher education institutions are caused by compromised credentials?
Data Encryption: Data encryption is a critical defense mechanism against unauthorized access. Use end-to-end encryption to ensure data is encrypted both in transit and at rest, preventing unauthorized access at all stages. Encryption protects the confidentiality and integrity of data at rest and in transit, rendering sensitive information unreadable to unauthorized users. Data encryption is another crucial measure that ensures sensitive data is protected both in transit and at rest. Encryption transforms data into unreadable code, making it difficult for cybercriminals to access or use the information even if they intercept it.
Good IT Hygiene: Good IT hygiene is critical for supporting the cybersecurity initiatives of educational institutions. Likewise, poor cybersecurity practices have far-reaching implications for data privacy, system functionality, and student preparedness. For example, failing to implement regular software updates and patches leaves institutional systems exposed to known vulnerabilities.
Routine Security Assessments: Routine security assessments help identify vulnerabilities before they are exploited. Conducting regular security audits and vulnerability assessments is essential for identifying weaknesses in an institution’s cybersecurity framework. These assessments help institutions detect potential vulnerabilities before they can be exploited by cybercriminals.
Cloud Security Posture Management: Cloud Security Posture Management practices help universities find misconfigurations, enforce security rules and monitor cloud systems in real time. They can spot weak access controls that expose student records, unsecured databases with financial details or outdated security settings that put research data at risk. Automated checks ensure compliance and help prevent data leaks before they become major issues.
Incident Response Plan: Having a well-structured incident response plan in place is critical for higher education institutions. This plan should outline the steps to be taken in the event of a cyberattack, including containment, recovery, and communication strategies.Defining precise, tested and efficient procedures for responding to various cyber incidents. These plans should include steps for containment, eradication of threats, recovery of data and communication with affected parties, ensuring minimal impact and a swift return to normal operations.
Cybersecurity Awareness Training: Human error remains one of the weakest links in cybersecurity. Providing cybersecurity awareness training to the campus community can reduce phishing attacks and credential theft. It is important to provide comprehensive training programs for all users-students, faculty, staff and even alumni. These programs should educate users on recognizing phishing attempts, the importance of strong, unique passwords, and the safe handling of sensitive information. Regularly updated training can significantly reduce the risk of human-error-related security breaches. Training students, faculty, and staff on cybersecurity best practices is an essential measure for higher education institutions.
Zero Trust Model: A zero trust model ensures that access to sensitive data is only granted on a need-to-know basis. When implementing a Zero Trust strategy, educational institutions should identify high-risk or high-value areas to pilot Zero Trust capabilities. For instance, a biotech research project with sensitive intellectual property would benefit greatly from a Zero Trust approach. The institution should start by thoroughly understanding the key assets involved in the project, such as research data, devices, applications, and networks. Network micro-segmentation can isolate the research project resources from the rest of the campus network. Detailed monitoring and analytics provide visibility into all access attempts. Starting with enterprise-grade authentication for wireless (and even wired) networks and certificate-based authentication (to replace passwords) will significantly strengthen network security.
CMS Security Best Practices: Enforcing security best practices (especially for institutions relying on content management systems (CMSs) like Drupal and WordPress, is essential. This includes regular updates to the CMS software and its plugins/modules, securing user accounts with strong authentication measures and maintaining secure database management practices. Implementing threat modeling and regular security monitoring can also help identify and mitigate risks.
Secure Hosting Providers: Choosing a secure hosting provider like Pantheon to harness specialized hosting solutions tailored for educational institutions and integrate enhanced security measures that protect against a wide range of cyber threats.
Strategic Partnerships: As a result, more leaders are looking to strategic partnerships to fill critical talent gaps and navigate budgetary shortfalls. Work with an independent cybersecurity firm to conduct an objective risk assessment that pinpoints your institution’s specific vulnerabilities and potential threats.

Fostering a Culture of Cybersecurity Awareness

Institutional culture plays a pivotal role in driving the success of cybersecurity policies. Higher education institutions require a multifaceted approach to cybersecurity that addresses technological, organizational, and cultural factors. Leadership support is critical in driving the mind shift necessary to align these elements. This shift in mindset starts with institutional culture.

Ongoing Training and Awareness: Implementing the cybersecurity measures cited above (as well as additional measures) is not sufficient without also conducting cybersecurity awareness and training programs for students, faculty, and staff. Well-informed individuals are the first line of defense against phishing attacks and other cyber threats. For this reason, institutions need to start integrating cybersecurity awareness into their educational programs. All employees, not just IT staff, should be aware of cyber threats and be equipped to respond appropriately. In addition to training new hires as they join the organization, make annual information security education mandatory for all employees. Once-a-year training is not enough. Changing awareness and behavior doesn’t happen overnight, and even after a change occurs, it can only be maintained through continual reinforcement. If you have the resources, consider a training partner. Your communications team can greatly enhance the effectiveness of training materials and awareness-building campaigns.
Contextualized Education: General education about data threats is important, but it’s just the beginning. To encourage information retention, put it in the context of people’s everyday lives. Enlist passionate people across all areas of the institution (not just IT) to champion security, model best practices, support infosec events and campaigns, and raise awareness.
Leveraging National Cybersecurity Awareness Month: October is National Cyber Security Awareness Month. Get creative with messaging this month by pairing cybersecurity messaging with engaging contests and prize incentives. Share links to national campaign coverage, events, and other activities on your social media feed or in your newsletter. While interviews with your own institutional leaders can work well, sometimes bringing in an outside expert on cybersecurity can increase engagement. Look for speakers from well-known organizations with unique stories that will pique employees’ interest.
HR Integration: The responsibility for protecting information should be incorporated into position descriptions, employee onboarding, and regular training schedules. As the liaison between leadership and employees, HR can also help foster a culture where it’s okay to ask questions.
Focus on People: Nearly all the top security threats facing higher education have a human dimension, which is why institutions that focus as much on people as technology will win the cybersecurity game. When it comes to staying vigilant against breaches, the more users know, the safer they’ll be. Cracks in your human firewall are as dangerous as those in your digital firewall. Some users are completely unaware of how valuable even partial information may be to potential hackers or that the institution’s most important property is intellectual, not physical. While it’s easier to raise awareness than to truly change user behavior, education is still one of the most important tools for safeguarding data.

Keeping Students Safe

While cybersecurity typically focuses on protecting systems and data from unauthorized access, it's equally important to consider the direct impact on student safety. There's a common misconception that today's students, being digital natives, are naturally savvy about cybersecurity risks. However, with cyber threats becoming more frequent and sophisticated, relying on this assumption can be dangerously complacent. The FBI's findings reveal a troubling trend: between 2018 and 2021, there was a sharper increase in cybercrime incidents involving victims aged 20 and under compared to those aged 60 and above. This shows the urgent need for institutions to educate their students about these risks actively.

Effective cybersecurity education should be a collaborative effort that involves students as active participants rather than a top-down mandate. Higher education institutions must engage students in meaningful ways to ensure they understand the risks and are motivated to adopt safe online practices. Workshops, seminars and interactive campaigns can be practical tools for raising awareness and fostering a culture of cybersecurity.

By involving students in developing and implementing cybersecurity policies, institutions can ensure these measures resonate more effectively with their lifestyles and daily activities. Moreover, creating student ambassador programs or peer-led initiatives can enhance engagement and reinforce the importance of cybersecurity within the student community.

The Role of Cloud Solutions

Cloud solutions that incorporate sophisticated controls and are provided by leading cloud and SaaS providers contribute to a more agile and efficient educational ecosystem. These solutions offer scalability, allowing institutions to adapt to changing needs. Moreover, cloud platforms facilitate collaboration and support activities, fostering a dynamic and interactive learning environment. The move to the cloud reduces demands on in-house IT resources and leads to improvements in cybersecurity.

However, educational institutions should carefully vet SaaS vendors and cloud providers, as not all providers share the same philosophy about cybersecurity investment. Institutions should start by partnering with SaaS providers with certifications such as ISO/IEC 27001, the globally recognized benchmark for information security management systems.

Additional Recommendations

Allocate sufficient resources to support cybersecurity initiatives.
Remain abreast of relevant laws, regulations, and industry standards pertaining to data protection and cybersecurity.
Develop a robust incident response and recovery plan to include a formal disaster recovery plan that outlines the steps to be taken in case of a cybersecurity breach.
Invest in regular cybersecurity training for all staff, students, and stakeholders.
Prioritize cybersecurity and support the implementation of security measures.
