Network Interruption Update: Restoring Connection and Ensuring Resilience

At Ascension, we are dedicated to delivering compassionate, personalized care to all, and an integral part of that mission is ensuring seamless and secure operations, especially regarding our digital infrastructure. In May 2024, we experienced a network interruption that impacted multiple Ascension systems, including our website and internal applications. This article provides an update on the incident, the restoration process, and the steps we’re taking to enhance our network’s resilience and security.

Understanding the Network Interruption

On May 10, 2024, at approximately 9:30 AM CST, our monitoring systems alerted us to a network anomaly affecting multiple servers and applications. The issue caused slowdowns and intermittent access problems for our patients, caregivers, and employees. Immediately, our IT teams sprang into action to identify the root cause and mitigate the impact.

Initial investigations revealed that the interruption was due to a distributed denial-of-service (DDoS) attack, a malicious attempt to overload our servers with traffic, causing them to become unresponsive. The attack exploited a vulnerability in our network infrastructure, overwhelming our servers with a flood of incoming data packets.

As soon as the issue was identified, we implemented our incident response plan. This included activating our Network Operations Center (NOC) and engaging our cybersecurity experts and external partners to assist in the mitigation and recovery process. We also notified law enforcement and are working closely with them to investigate the source of the attack.

Restoring Systems and Services

Our first priority was to stabilize the network and restore critical systems and services. We implemented traffic filtering and routing measures to block the malicious traffic and redirect it away from our servers. By 1:00 PM CST, we had successfully mitigated the attack, and our systems began to return to normal functionality.

To ensure a smooth recovery, we followed a careful, phased approach, bringing systems back online in a controlled manner to avoid further disruptions. By 6:00 PM CST, all critical applications, including our electronic health record system, were fully functional, and our website was accessible to the public.

We understand that any disruption to our services can impact the care we provide and cause inconvenience to our patients and caregivers. That’s why we had backup procedures in place to ensure continuity of care during the interruption. Our caregivers utilized established downtime procedures, including manual processes, to continue delivering safe and effective care to our patients.

Enhancing Resilience and Security

While we were able to swiftly mitigate the attack and restore our systems, we recognize the importance of continuously enhancing our network’s resilience and security. As such, we are taking this opportunity to implement several measures to fortify our defenses and reduce the risk of similar incidents in the future:

  • Upgrading Network Infrastructure: We are investing in advanced network infrastructure upgrades to enhance our DDoS protection capabilities. This includes implementing next-generation firewalls, improving traffic filtering, and increasing bandwidth capacity to better handle high-volume attacks.
  • Enhancing Monitoring and Detection: We are expanding our monitoring and detection capabilities to identify potential threats earlier. This includes deploying advanced behavioral analytics tools that can detect anomalous activity and potential security breaches in real time.
  • Strengthening Cybersecurity Training: We are reinforcing our commitment to cybersecurity awareness and training for all employees. This includes regular simulations, phishing tests, and educational programs to ensure everyone understands their role in maintaining a secure digital environment.
  • Fortifying Third-Party Vendor Security: We are conducting a comprehensive review of our third-party vendors and partners to ensure they adhere to our stringent security standards. This includes assessing their cybersecurity practices, implementing additional security controls, and establishing clear guidelines for data sharing and protection.
  • Implementing Redundancy Measures: To ensure uninterrupted operations during future incidents, we are establishing redundant systems and backup sites. This includes diversifying our network infrastructure across multiple data centers and cloud providers, ensuring that critical services remain accessible even in the face of disruptions.

Impact and Recovery Efforts

The network interruption impacted multiple Ascension facilities and operations across the country. While there was no breach of sensitive data or patient information, we recognize the disruption it caused to our day-to-day operations. Here’s an overview of the impact and our recovery efforts in key areas:

  • Patient Care: Our top priority remains delivering safe and effective patient care. During the interruption, our caregivers swiftly implemented established downtime procedures, ensuring that patient safety was never compromised. While some non-critical services were temporarily impacted, we ensured that urgent and emergency care needs were addressed without delay.
  • Electronic Health Records (EHR): Our EHR system was temporarily affected by the interruption, causing delays in accessing patient records. However, our caregivers were able to utilize offline documentation methods, and all patient data remained secure and confidential. We have since restored full functionality to our EHR system, and patient records are now accessible as usual.
  • Scheduling and Appointments: The network issues caused temporary disruptions to our scheduling systems, impacting appointment bookings and reminders. We are working closely with patients to reschedule any affected appointments and ensure continuity of care. We have also implemented additional backup measures to ensure scheduling accuracy and reliability in the future.
  • Billing and Insurance: There were minor delays in processing insurance claims and patient billing due to the network interruption. Our teams are working diligently to resolve these delays, and we are coordinating with insurance providers to ensure timely reimbursement. We apologize for any inconvenience caused and are taking steps to prevent similar issues in the future.

Lessons Learned and Future Improvements

As we reflect on this incident, several key lessons have emerged that will shape our future strategies:

  • The Importance of Proactive Defense: This incident underscores the evolving nature of cyber threats and the need for proactive defense measures. We are committed to staying ahead of emerging threats by continuously evaluating and upgrading our security posture.
  • Resilience through Redundancy: The value of redundancy and backup systems has been reinforced. We are investing in diverse network paths and distributed infrastructure to ensure uninterrupted operations, even in the face of significant cyber events.
  • Collaboration and Partnerships: Effective response and recovery rely on strong partnerships. We are grateful for the support and collaboration of our external partners and law enforcement agencies, and we will continue to foster these relationships to enhance our collective cyber resilience.
  • Clear and Transparent Communication: We recognize the importance of clear and timely communication during such events. Going forward, we will enhance our communication strategies to keep our patients, caregivers, and stakeholders informed during similar incidents.

Looking Ahead

As we move forward, Ascension remains committed to safeguarding our systems and data while delivering uninterrupted, exceptional care. We view this incident as an opportunity to strengthen our defenses and improve our ability to withstand future cyber challenges.

We extend our sincere gratitude to our patients, caregivers, and partners for their understanding and support during this time. Your patience and cooperation have been invaluable as we worked to resolve this issue.

Finally, we want to assure everyone that the security and privacy of patient information remain our utmost priority. We will continue to invest in the latest technologies, train our workforce, and collaborate with industry experts to stay at the forefront of cybersecurity.
