How schools can ensure data safety in the era of digital learning

By: Rick Vanover, Senior Director of Product Strategy, Veeam

Whether you are a teacher, parent, IT professional, or student, you have witnessed the extraordinary transition the education sector has recently undergone. Despite our schools having already facilitated distance, digital and remote learning for some years now, there is no doubt that the global lockdown has acted as a catalyst for further rapid and momentous change. 

As our systems continue to evolve, it is crucial that our data security strategy advances at the same speed. This means ensuring watertight protection of educational data against one of the most common forms of attack, ransomware.

Data collected on students, staff, and teachers may be highly personal or sensitive and could include student performance data, demographic characteristics, or responses to surveys. This data is attractive to a potential hacker because they understand the impact a data breach could have on an institution’s reputation, and so therefore see a better chance of obtaining a ransom for their crime.

By taking proactive as opposed to reactive precautions, this face-off might never be necessary. IT teams within schools should consider a data protection strategy on a foundation of education, implementation, and remediation to be impermeable from the word go.

Understanding the risks

The journey of understanding starts after the threat actors are identified. Remote desktop protocol (RDP) or other remote access tools, phish, and software updates are the three main mechanisms for entry. Knowing this could help your institution focus its investment strategically, enabling maximum resilience against ransomware from an attack vector perspective.

Most IT administrators use RDP for their daily work, with many RDP servers still directly connected on the Internet. As a result, over half of ransomware attacks currently use RDP as an entry pathway. Those not accessing via RDP may instead choose phish mail as their method of choice. If you are ever unsure if you have received a phishing email, there are two popular tools that can help assess the risk to your organization These are Gophish and KnowBe4. It is also essential to keep in mind the need to update critical categories of IT assets such as operating systems, applications, databases, and device firmware. Extend this thorough approach to data centers, too, as they can be just as susceptible to attack as the data housed on-site.

Implementation

When it comes to a ransomware attack, its resiliency hinges on how the backup solution is implemented, the behavior of the threat, and the course of remediation. As an important part of ransomware resiliency, the implementation of backup infrastructure is a critical step.

Backup repositories are an essential storage resource when it comes to ransomware

resiliency, so it is recommended that access to those within the organization is not permitted. Insiders having the permissions to access this data could lead to potential leaks outside of the organization, so it is recommended that these responsibilities are managed by a third party, where possible.

Remediation

Despite ensuring your institution is educated around the threats of ransomware and implements the correct techniques accordingly, you should always be prepared to remediate a threat where necessary.

If you do suffer an attack, your next steps to remediating ransomware are:

• Do not pay the ransom.
• The only option is to restore data.

One of the hardest parts of recovering from a hack is decision authority. Make sure you have a clear protocol in place that establishes who will make the call to restore or to failover your data in the event of a disaster. Within these business discussions, agree on a list of security, incident response, and identity management contacts that you can call on if needed. When a breach happens, time is of the essence, so you will thank yourself for having prepared in advance.

Much like you would invest in insurance for your home, you should consider backup an investment in the same vein. It is something you hope never to need, but if the worst happens, your institution is protected, and your staff and students’ data is safe. By properly educating your colleagues on the risks, implementing the appropriate infrastructure, and having the appropriate remediation protocols in place, you will not only increase your resiliency against ransomware attacks but also avoid data loss, financial costs, or reputation damage to your school.
