📚Lessons Learned
To enhance cybersecurity resilience, the following recommendations are proposed:
- **Regular Vulnerability Assessments:** Implement frequent assessments and penetration testing to identify and remediate vulnerabilities before they can be exploited.
- **Incident Response Planning:** Develop and regularly update an incident response plan that includes protocols for dealing with ransomware and data breaches.
- **Awareness and Training Programs:** Conduct regular training sessions for staff and faculty to recognize phishing attempts and suspicious activities.
- **Patch Management Strategy:** Establish a robust patch management routine for all critical systems to ensure that vulnerabilities are remediated promptly.
- **Data Encryption:** Implement end-to-end encryption for sensitive data to minimize the impact of potential data breaches.
By adopting these measures, Harvard University and similar institutions can better protect themselves against future ransomware attacks and data breaches.
