Introduction

Cybersecurity incidents pose an increasing threat to hospitals and healthcare providers. The widespread adoption of electronic health records (EHRs), along with the connectivity of medical devices and systems, has expanded hospitals’ digital footprints and potential vulnerabilities. Healthcare organizations hold extremely sensitive data and disruption of services can be life-threatening. This makes them attractive targets for cyber criminals.

Recent years have seen a surge of successful cyberattacks on healthcare entities, from ransomware campaigns to data breaches. One study found a 125% year-over-year increase in attacks in 2020. Hospitals often lack resources dedicated to cybersecurity compared to other industries. Legacy systems containing outdated software or lacking security features compound the risks. Attackers exploit these vulnerabilities to infiltrate networks, steal data, disrupt operations, and extort funds. The consequences can be severe, jeopardizing patient care, safety, privacy and trust in the institution.

Common Types of Cybersecurity Incidents

Hospitals face a variety of cybersecurity threats that can disrupt operations and put patient data at risk. Some of the most common types of incidents include:

Ransomware

Ransomware is a form of malware that encrypts files on a network, rendering them inaccessible. Attackers demand a ransom payment in cryptocurrency to decrypt the files. Ransomware can spread quickly in a network environment like a hospital, encrypting critical medical records and devices. This can severely hamper a hospital’s ability to operate and provide care.

Phishing

Phishing involves cybercriminals sending fraudulent emails or texts designed to trick users into revealing passwords or sensitive information. Healthcare employees are frequent targets of phishing scams. A successful phishing attack can result in stolen credentials that attackers use to infiltrate hospital systems and access patient data.

Data Breaches

Hospitals store massive amounts of sensitive patient health information that is highly valued on the black market. Lax security controls can enable attackers to breach hospital databases and steal patient records containing personal and medical data. Preventing unauthorized data exfiltration is a major focus of healthcare cybersecurity programs.

Insider Threats

The insider threat involves staff members or contractors misusing access intentionally or unintentionally. For example, a disgruntled employee may steal and publicly disclose patient information. Accidental insider threats can occur when an employee falls for a phishing scam and clicks a malicious link that deploys malware. Managing insider risk through training and monitoring is key.

Prevention Strategies

Hospitals use various strategies and technologies to prevent cybersecurity incidents. Some key prevention methods include:

Employee Training

Training employees on cybersecurity best practices is critical. Common training topics include how to spot phishing emails, use strong passwords, avoid risky web browsing on work devices, and follow policies on data access. Regular cybersecurity awareness training can help prevent incidents stemming from employee errors.

Security Software

Installing endpoint detection and response software, antivirus programs, firewalls, and other security tools can prevent malware, unauthorized access, and other threats. Keeping software patched and updated is also key.

Access Controls

Controlling access to sensitive systems and data prevents unauthorized activity. Methods include role-based access, multi-factor authentication, and limiting privileges.

Encryption

Encrypting data, whether in motion or at rest, helps prevent breaches involving stolen devices or compromised networks. Hospitals can encrypt patient health records, financial data, emails, backups, and more.

Ongoing prevention requires a layered defense combining people, processes, and technology. Hospitals must remain vigilant against evolving cyber threats.

Detection and Monitoring

Hospitals utilize advanced systems and processes to detect cybersecurity incidents and monitor their networks. This allows them to identify threats early and respond quickly.

Security Operations Centers (SOCs)

Many hospitals maintain 24/7 security operations centers (SOCs) staffed by cybersecurity professionals. The SOC monitors the hospital’s networks, endpoints, servers, medical devices, and other systems using security information and event management (SIEM) software. The SIEM aggregates and analyzes log data in real-time to detect anomalies and threats. When an incident is detected, the SOC team investigates and coordinates the response.

Intrusion Detection Systems

Network intrusion detection systems (IDS) and host intrusion detection systems (HIDS) provide real-time monitoring to detect malicious activity. IDS sensors analyze inbound and outbound network traffic looking for known attack patterns and anomalies. HIDS agents monitor activity on individual devices. When suspicious activity is found, alerts are generated so the SOC team can investigate.

Log Analysis

Extensive log data is collected from all IT systems and analyzed to identify security events. Logs provide detailed audit trails of user activity that is invaluable during incident investigations. Security teams use log management systems to aggregate logs in one place and leverage analytics tools to identify threats.

Incident Response Plans

Hospitals need comprehensive incident response plans to handle cybersecurity incidents effectively. These plans outline the procedures to follow when an incident occurs and help coordinate the response. Key elements of a response plan include:

Containment

The first priority is containing the incident to prevent further damage. This may involve isolating affected systems, blocking suspicious IP addresses, disabling user accounts, or taking systems offline. For malware infections, containment aims to prevent the malware from spreading and communicating with command and control servers.

Eradication

Once an incident is contained, the next step is to eradicate the threat. This involves removing malware, addressing vulnerabilities being exploited, restoring systems from clean backups, and implementing other remediation measures. The goal is to eliminate the attacker’s foothold and return systems to a trustworthy state.

Recovery

After eradicating a threat, recovery procedures aim to restore normal operations. This may involve rebuilding systems, validating data integrity, resetting accounts and passwords, implementing additional monitoring, and bringing systems back online. The hospital should validate that the incident has been fully resolved before resuming regular activity.

Having detailed playbooks for different incident scenarios will help the response team follow proven procedures during high-stress situations. Regularly testing and updating the plan is also critical for keeping it effective. With proper planning, hospitals can respond decisively when incidents occur.

Notifying Patients and Regulators

Hospitals have legal and ethical obligations to notify patients and regulators in the event of a cybersecurity incident involving protected health information (PHI).

Under HIPAA regulations, healthcare organizations must notify affected individuals “without unreasonable delay” following the discovery of a breach impacting 500 or more people. Notifications must also be provided to prominent media outlets serving the location. Smaller breaches affecting under 500 individuals may be documented in an annual log submitted to the Department of Health and Human Services.

In addition to HIPAA, state data breach laws may impose additional notification requirements in the event of a cyber incident. Timeframes for notification vary by state, ranging from 30 to 90 days following discovery of a breach.

Failure to properly notify patients and regulators as required can result in HIPAA violations with substantial financial penalties. It is critical for hospitals to have well-documented breach response plans to ensure compliance.

Managing Reputation

Beyond mandatory reporting, hospitals should also consider the reputational implications of a cybersecurity incident. Breaches can erode patient trust if not handled transparently.

Proactive communications demonstrating the organization’s cybersecurity posture, quick response, and steps taken to prevent future incidents can help reassure patients. Clear messaging around the extent of the breach, number of patients impacted, and types of information exposed is also important.

Hospitals should work closely with communications and legal teams when notifying patients to provide the appropriate information while also managing reputational risks. Ongoing engagement with patients and the community following the incident can further help rebuild trust.

Using Cyber Insurance

Cyber insurance can provide hospitals with financial protection in the event of a cyber incident. Some key considerations around cyber insurance for hospitals include:

Coverage Options

  • Data breach/privacy liability – Covers costs related to breach notification, credit monitoring, forensic investigations, legal services, PR services, etc.
  • Network security liability – Protects against damages to third parties from failure of security protections.
  • Cyber extortion – Covers ransoms and response costs for extortion-related threats.
  • Business interruption – Reimburses for income loss and extra expenses from IT outages.
  • Cyber crime – Covers direct losses due to hacking, social engineering, etc.

Pros

  • Financial protection for expensive incident response and recovery costs.
  • Access to breach coaches and legal/forensic expertise.
  • Motivation for improving security posture to obtain discounts.
  • PR support and notification assistance.

Cons

  • Premiums and deductibles can be costly, with limits on coverage.
  • Require showing due diligence in security practices for claims approval.
  • Complex policies with exclusions and specific requirements.
  • Doesn’t cover reputational damages, loss of future business, etc.
  • Claims can impact future premiums and coverage eligibility.

Overall, cyber insurance can be a valuable risk transfer tool for hospitals to mitigate financial impacts of cyber incidents, but policies must be evaluated closely, and coverage limitations understood. Improving in-house security and preparedness remains imperative.

Improving Resilience

Hospitals can improve their resilience to cybersecurity incidents by implementing comprehensive backup systems, disaster recovery plans, and conducting regular drills.

Backup Systems

Hospitals should have redundant backups of all critical systems and data, with both onsite and offsite backups. Onsite backups provide rapid recovery, while offsite backups protect against damage to facilities. Backups should be automatically created and tested regularly.

Disaster Recovery

A disaster recovery plan outlines how a hospital will maintain or quickly resume critical operations during a cybersecurity incident. This includes setting RTOs and RPOs for systems, detailing failover procedures, and designating response teams. Plans should cover scenarios like ransomware, DDoS attacks, and data corruption.

Drills

Conducting periodic cybersecurity incident drills helps evaluate and improve response plans. Drills can range from technical exercises like restoring from backup to full-scale simulations with teams responding as they would to a real incident. Lessons learned from drills should be incorporated into plans and processes.

Staff Training

A hospital’s staff is its first line of defense against cyber attacks. Ongoing education and training is crucial to ensure all employees understand cyber risks and best practices. This includes:

  • Annual cybersecurity training – Hospitals should require all staff to complete training on protecting patient data, proper use of devices, phishing identification, and reporting of incidents. Training should be updated regularly to address new threats.
  • Simulated phishing attacks – Phishing emails are a common infection vector. Running regular simulated phishing campaigns helps train employees to identify and report suspicious emails. Metrics can identify areas to improve.
  • Role-based training – Training should be tailored by role. Clinical staff need education on using devices securely. IT staff require technical training on threats. Leadership needs risk management training.
  • New hire orientation – Onboarding is a chance to set expectations around cybersecurity practices and awareness from day one. This establishes a culture of security.
  • Ongoing refreshers – Cybersecurity training cannot be one-and-done. Regular lunch-and-learn sessions and refresher courses reinforce secure practices and keep skills sharp.

With comprehensive, role-based training and testing, a hospital’s staff can become an obstacle, not a target, for cyber criminals. Proper education is essential to create a human firewall.

Third Party Risk Management

Hospitals rely heavily on third party vendors and service providers, which can create cybersecurity risks if not properly managed. Here are some best practices for hospitals to manage third party cyber risks:

Vendor Selection

  • Conduct thorough due diligence on potential vendors, examining their cybersecurity policies, procedures, and track record.
  • Prioritize working with vendors that demonstrate a strong commitment to cybersecurity.
  • Include cybersecurity requirements in vendor RFPs and selection criteria.

Audits

  • Perform audits and risk assessments of critical vendors on a regular basis.
  • Require vendors to undergo independent cybersecurity audits annually.
  • Review vendor audit reports to verify compliance and identify any gaps or issues to be addressed.

Contract Terms

  • Include cybersecurity requirements and responsibilities in vendor contracts.
  • Mandate incident notification and response plans in contracts.
  • Include indemnification clauses and cyber insurance requirements.
  • Ensure contract language holds vendors accountable for meeting cybersecurity standards.
  • Include right-to-audit and right-to-monitor clauses in contracts.

Proactively managing third party cyber risks is essential for hospitals to limit their exposure and exercise proper due diligence. Taking steps to assess, monitor, and engage vendors on security is key.
