For decades, schools have become more reliant on technology. Smart devices have made their way into classrooms and hallways, connecting to the broader network and potentially introducing new threats.
For school districts, it’s not enough to wring your hands and hope IT can deal with any problems that might crop up.
Education has become one of the top targeted industries for cyber attacks, and it’s more a matter of when you’ll get hit. That’s why you need a robust Cyber Incident Response Plan.
A Cyber Incident Response Plan (IRP) is a foundational document, usually part of a broader cybersecurity annex, that outlines how your school will respond to a data breach, cyberattack, or other security incident.
Your school district probably already has an emergency response plan in place detailing the protective actions you should take. Your employees are probably well-prepared for natural disasters, fires, or even violent security incidents.
Everyone knows who is responsible for emergency management. Everyone knows how to reach emergency medical services and how to perform basic first aid. There is an evacuation plan in place, as well as regular incident response planning drills and meetings to prepare students and teachers to deal with a physical security incident.
Unfortunately, the digital environment we live in means that we have to extend emergency planning to include cyber incident handling.
Cyber incident response planning will:
Remember, your school district is sitting on a goldmine of information— from healthcare data to Social Security numbers, financial information to addresses and phone numbers.
This information can be sold online, which is why schools are reporting increasing numbers of successful and attempted security breaches.
You may encounter malware, ransomware, phishing, malicious leaks, and a lot more. These incidents can impact business continuity and normal operations and lead to negative publicity and critical financial losses.
Your cyber emergency response plan doesn’t have to be complicated. You can find an incident response plan template online to get you started. Having a plan and cybersecurity annex in place is the first and best step you can take when it comes to dealing with security incidents and improving your defensive posture. Here’s a general outline that many incident response plans follow:
During this phase, the focus is on preparing for potential cyber incidents in the future. Start by conducting a thorough risk assessment tailored to the school’s environment. Find out what threats your school might be facing and prioritize risks based on severity. That way, you can allocate your resources where they are needed the most.
Establish a response team comprising members from IT, legal, human resources, counseling, and external vendors if necessary. Think of them as the first responders on the scene. Define their roles carefully to ensure that everyone knows what their responsibilities are during and after a cyber security event.
Create a detailed policy outlining your school or district’s approach to cyber incident management, including your goals and tactics. Outline the methods you’ll use to identify a security incident, including suspicious activity monitoring and log analysis, and define steps to stop the incident from spreading, such as isolating infected systems or revoking access privileges. You should also describe the process for restoring your system and investigating the root cause so it can be prevented in the future.
Make sure that you know exactly who you need to inform if there’s an incident – from parents to teachers to students and vendors. Put communication protocols for internal and external stakeholders in place, including backup channels for communication if emails or the intranet goes down.
During this phase, the focus shifts to detecting and analyzing potential cyber incidents as quickly as possible.
Implement tools that continuously monitor network traffic, cloud activity, system logs, and security events for signs of anomalies, like Endpoint Detection and Response (EDR) software. Configure these systems to identify deviations from normal behavior patterns, like unusual spikes in traffic, unauthorized access attempts, suspicious file activity, or changes in configuration settings.
You can streamline incident detection by automating tasks like analyzing log files, correlating events, and identifying known threats using rules-based engines or machine-learning models. This enables faster response times and reduces reliance on manual analysis.
Conduct a comprehensive investigation to understand the nature and scope of the potential incident whenever an alert is triggered. Analyze your logs, collect evidence, and correlate events across different systems to determine the root cause and potential impact. Prioritize incidents based on their severity, considering factors like the type of threat, affected systems, potential data loss, and disruption to your operations. This helps focus resources on the most critical issues first.
This crucial phase of the IRP focuses on minimizing the impact of the detected incident and restoring normal operations as quickly as possible.
As soon as an incident is confirmed, you have to act quickly to prevent it from spreading and limit potential damage. Prioritize your critical systems and at-risk data. Isolate compromised systems from the network, disable user accounts, and restrict access to affected resources to contain the threat within a controllable boundary. Consider temporarily disabling network connections or specific services connected to the incident if necessary to prevent lateral movement of attackers.
Define categories for incident severity based on factors like potential impact, affected systems, data involved, and business disruption, e.g., low, medium, high, and critical. Establish clear criteria for escalating incidents to higher levels (e.g., vendors or external authorities) based on their severity and complexity.
Once the threat is contained, eliminate the root cause of the incident. This may involve patching vulnerabilities, removing malware, or disabling compromised accounts. Use backups or other recovery methods to restore affected systems and thoroughly test those systems to confirm they are clean and function correctly before resuming normal operations. You’ll also need clear procedures for safely resuming normal operations, including user access restoration, password resets, and communication strategies.
What you do after an incident is just as important as responding to the incident itself. During this phase, it’s important to take steps to prevent it from happening and reassure your stakeholders that the incident has been handled appropriately and thoroughly.
Conduct post-incident reviews to identify areas for improvement and implement measures to prevent future incidents based on lessons learned. Document all actions that were taken during containment and eradication so that your plan can be improved and updated. After the incident, conduct a post-mortem analysis to identify areas for improvement.
Regularly communicate the incident status and response efforts to parents, guardians, students, and staff to foster transparency and awareness. You may also want to speak to law enforcement and industry bodies.
An incident response plan (IRP) acts as your organization’s shield against the ever-evolving landscape of cyber threats. But just like any defensive gear, it needs regular maintenance to stay effective. New vulnerabilities emerge, attack methods shift, and adversaries adapt. Security tools and best practices continuously evolve. Your IRP needs to stay abreast of these changes to address the latest threats effectively.
Conduct comprehensive reviews of your IRP at least annually or even more frequently if you need to. Ensure that representatives from IT, security, legal, communications, and other relevant departments participate in the review process.
And if you aren’t sure where to start – get in touch with a cybersecurity vendor you can trust. They will have the expertise to help you put together your plan and keep it updated.
