Healthcare Cybersecurity Best Practices 2026


Key Takeaways

  • Healthcare was the most breached industry in the United States for the fifth consecutive year in 2025, with over 700 reported breaches affecting more than 170 million patient records. The average cost of a healthcare data breach reached $10.93 million — more than double the cross-industry average.
  • Ransomware remains the dominant threat to healthcare organizations. In 2025, ransomware attacks disrupted clinical operations at over 100 US hospitals, forcing emergency department diversions, surgical cancellations, and weeks-long EHR outages.
  • The threat landscape has shifted from opportunistic attacks to targeted campaigns against healthcare. Threat actors specifically target healthcare because patient data is the most valuable data on the black market ($250–$1,000 per record vs $5–$10 for a credit card), because hospitals cannot afford extended downtime, and because healthcare IT infrastructure is chronically under-invested.
  • Cybersecurity in healthcare is not just an IT problem — it is a patient safety problem. When systems go down due to a cyberattack, clinical staff revert to paper processes, medication errors increase, diagnostic delays occur, and patient outcomes suffer. Multiple studies have linked hospital cyberattacks to measurable increases in patient mortality.
  • Taction Software’s security audit findings across US healthcare clients reveal that 78% of organizations have at least one critical vulnerability related to legacy system connectivity, unpatched integration interfaces, or misconfigured cloud services — often in the interoperability layer connecting clinical systems.

The Healthcare Cybersecurity Threat Landscape in 2026

The healthcare cybersecurity landscape in 2026 is defined by three converging trends: increasingly sophisticated threat actors, an expanding attack surface driven by digital health adoption, and a persistent shortage of cybersecurity talent in the healthcare sector.

Scale of the problem. The HHS Office for Civil Rights breach portal recorded over 700 breaches of unsecured PHI affecting 500+ individuals in 2025. The total number of affected records exceeded 170 million — meaning more than half of the US population had their health data compromised in a single year.

Financial impact. IBM’s Cost of a Data Breach Report found that healthcare breach costs averaged $10.93 million per incident in 2025, the highest of any industry for the fifteenth consecutive year. This includes direct costs (incident response, notification, legal fees, regulatory fines) and indirect costs (patient churn, reputation damage, increased insurance premiums).

Operational impact. Beyond financial costs, healthcare cyberattacks directly affect patient care. A 2025 study published in JAMA found that hospitals experiencing ransomware attacks saw a 21% increase in in-hospital mortality for patients with time-sensitive conditions during the period of system downtime. This transforms cybersecurity from a technology issue into a clinical quality issue.

Regulatory response. HHS proposed updated HIPAA Security Rule requirements in late 2024, with final rules expected in 2026. The proposed updates include mandatory multi-factor authentication, mandatory encryption, network segmentation requirements, and 72-hour restoration timelines for critical systems. Healthcare organizations should prepare for these requirements now rather than waiting for the final rule.


Top Cyber Threats Targeting Healthcare

Ransomware

Ransomware remains the most destructive threat to healthcare. Modern healthcare ransomware attacks follow a predictable pattern: initial access (usually through phishing or exploiting a vulnerable internet-facing system), lateral movement through the network over days or weeks, exfiltration of sensitive data, encryption of critical systems, and a double extortion demand (pay to decrypt AND pay to prevent data publication).

2025 healthcare ransomware trends:

  • Average ransom demand for healthcare organizations exceeded $4.5 million
  • Average downtime from a healthcare ransomware event was 23 days
  • 65% of healthcare ransomware victims reported clinical care disruption
  • Double extortion (encrypting data + threatening to publish it) was used in over 80% of attacks
  • Ransomware-as-a-Service (RaaS) groups specifically recruited affiliates with healthcare targeting experience

Phishing and Social Engineering

Phishing remains the most common initial access vector. Healthcare-specific phishing campaigns impersonate insurance companies, EHR vendors, medical device suppliers, regulatory bodies (fake HIPAA audit notices), and even patients.

Business Email Compromise (BEC) is growing rapidly in healthcare. Attackers compromise or spoof executive email accounts to redirect vendor payments, authorize fraudulent wire transfers, or gain access to sensitive systems.

Supply Chain Attacks

Attacks targeting healthcare technology vendors, service providers, and software supply chains have increased dramatically. A single compromised vendor can provide access to hundreds of healthcare organizations simultaneously. The MOVEit and SolarWinds attacks demonstrated how supply chain compromises ripple through healthcare.

Insider Threats

Healthcare has a uniquely high insider threat risk because large numbers of staff require access to sensitive patient data. Insider threats include malicious actors (employees selling patient data, snooping on celebrity records) and negligent insiders (staff falling for phishing, using weak passwords, losing unencrypted devices).

Exploitation of Legacy Systems

Many healthcare organizations run legacy systems — older Windows versions, unpatched applications, deprecated protocols — that contain known, exploitable vulnerabilities. These legacy systems are often connected to clinical networks, providing attackers with a pathway from a vulnerable legacy system to critical clinical infrastructure.

AI-Powered Attacks

Emerging in 2025–2026, AI-generated phishing emails, deepfake voice calls impersonating executives, and AI-assisted vulnerability discovery are making attacks more sophisticated and harder to detect.


Why Healthcare Is Uniquely Vulnerable

Complex, interconnected environments. A typical hospital network connects thousands of devices: workstations, medical devices, IoT sensors, building management systems, guest Wi-Fi networks, vendor VPN connections, and cloud services. Each connection point is a potential entry point.

Legacy technology dependence. Healthcare organizations often run critical applications on legacy systems that are difficult or impossible to patch. A Windows Server 2012 system running a critical lab interface cannot simply be taken offline for upgrades without disrupting clinical operations.

High staff turnover and diverse workforce. Healthcare organizations employ thousands of staff with varying levels of technical sophistication — physicians, nurses, administrative staff, environmental services, volunteers, contractors. Security training must reach all of them, and turnover ensures there are always untrained users on the network.

24/7 operational requirement. Healthcare cannot shut down for maintenance windows the way other industries can. Patching, upgrades, and security changes must be done without disrupting clinical care — which often means they are deferred.

Budget constraints. Despite the high cost of breaches, healthcare cybersecurity budgets remain disproportionately low. Many healthcare organizations allocate less than 6% of their IT budget to cybersecurity, compared to 10–15% in financial services.

Regulatory complexity. Healthcare organizations must comply with HIPAA, state breach notification laws, potentially FDA requirements for medical devices, and emerging federal cybersecurity requirements — each with different standards and enforcement mechanisms.


Network Security Best Practices

Network Segmentation

Network segmentation is the single most impactful network security control for healthcare. It limits lateral movement — even if an attacker compromises one system, segmentation prevents them from reaching critical clinical systems.

Recommended segments:

  • Clinical network: EHR systems, clinical workstations, clinical applications
  • Medical device network: Infusion pumps, patient monitors, imaging systems, lab instruments
  • Administrative network: Business office workstations, email, HR systems
  • Guest network: Patient and visitor Wi-Fi (completely isolated from clinical networks)
  • Integration network: Integration engines, interface servers, API gateways
  • Management network: IT administration, security tools, monitoring systems
  • DMZ: Internet-facing services, patient portals, telehealth platforms

Implementation: Use VLANs with firewall rules between segments. Define explicit allow rules for necessary traffic (HL7 messages between integration engine and EHR, for example) and deny all other cross-segment traffic by default.

Firewall Configuration

  • Default-deny policy: block all traffic that is not explicitly allowed
  • Segment-to-segment rules: define specific allowed traffic flows between network segments
  • Outbound filtering: restrict outbound connections to known-good destinations (prevents command-and-control communication)
  • Geo-blocking: block inbound traffic from countries where you have no business operations
  • TLS inspection: decrypt and inspect encrypted traffic at the network perimeter (with HIPAA-appropriate safeguards for PHI in transit)

Intrusion Detection and Prevention

Deploy network-based intrusion detection/prevention systems (NIDS/NIPS) at segment boundaries and at the network perimeter. Configure signatures for healthcare-specific attack patterns:

  • HL7 protocol anomalies (malformed messages, unexpected message types)
  • DICOM protocol exploitation attempts
  • FHIR API abuse patterns (credential stuffing, excessive data queries)
  • Known ransomware communication patterns

DNS Security

  • Implement DNS filtering to block known malicious domains
  • Use DNS logging and monitoring to detect suspicious domain queries
  • Consider DNS over HTTPS (DoH) for outbound DNS to prevent DNS snooping
  • Block DNS queries to newly registered domains (common in phishing campaigns)

Zero Trust Architecture

Move toward a zero trust model where no device or user is trusted by default, even if they are inside the network perimeter:

  • Verify every access request regardless of source location
  • Enforce least-privilege access for every connection
  • Continuously monitor and validate trust throughout the session
  • Assume breach — design controls assuming attackers are already inside the network

Endpoint and Device Security

Workstation Hardening

  • Deploy endpoint detection and response (EDR) on all workstations — not just traditional antivirus
  • Enable host-based firewalls with deny-by-default outbound rules
  • Disable unnecessary services and ports
  • Remove local administrator privileges from standard user accounts
  • Enable full-disk encryption (BitLocker, FileVault)
  • Configure automatic screen lock after 5 minutes of inactivity
  • Maintain automated patching with a 72-hour deployment target for critical patches

Mobile Device Management

Healthcare staff increasingly use mobile devices for clinical work — smartphones for secure messaging, tablets for bedside documentation, laptops for telehealth.

  • Deploy Mobile Device Management (MDM) for all devices accessing PHI
  • Enforce device encryption
  • Enable remote wipe capability for lost or stolen devices
  • Require device PIN/biometric authentication
  • Containerize healthcare applications to separate PHI from personal data
  • Block jailbroken or rooted devices from accessing clinical systems

USB and Removable Media

  • Disable USB storage device access on clinical workstations by default
  • Use device control software to whitelist only approved USB devices
  • Encrypt any approved removable media containing PHI
  • Log all USB device connections for audit purposes

Identity and Access Management

Multi-Factor Authentication

MFA is the single most effective control against credential-based attacks. The proposed HIPAA Security Rule update will make MFA mandatory for all systems containing ePHI.

Where to implement MFA:

  • All remote access (VPN, remote desktop, cloud applications)
  • All administrative access to servers, network devices, and security tools
  • All access to EHR and clinical applications
  • All access to patient portals (at minimum, offer MFA as an option for patients)
  • All cloud service console access (AWS, Azure, GCP management consoles)

MFA methods ranked by security:

  1. FIDO2 hardware security keys (strongest — phishing-resistant)
  2. Authenticator app with push notification (strong)
  3. Authenticator app with TOTP code (strong)
  4. SMS-based OTP (better than nothing, but vulnerable to SIM swapping)

Privileged Access Management

Administrative and privileged accounts (domain admins, database admins, EHR system admins) are the highest-value targets for attackers.

  • Use a privileged access management (PAM) solution to vault and rotate privileged credentials
  • Implement just-in-time access — grant admin privileges only when needed, for a limited time
  • Require MFA plus approval workflow for privileged access
  • Log and record all privileged sessions
  • Use separate admin accounts (not the same account used for email and daily work)

Role-Based Access Control

  • Define roles based on job function with minimum necessary access to PHI
  • Review access permissions quarterly — remove access that is no longer needed
  • Disable accounts immediately upon employee termination (automate with HR system integration)
  • Implement access expiration for contractor and temporary accounts
  • Use break-the-glass procedures for emergency access — documented, logged, and reviewed

Data Encryption Standards

Encryption at Rest

  • AES-256 for all databases containing ePHI
  • Full-disk encryption on all endpoints (workstations, laptops, servers)
  • Encrypted backups — backup media is one of the most common sources of healthcare data breaches
  • Encryption of archive and long-term storage
  • Key management using hardware security modules (HSM) or cloud KMS

Encryption in Transit

  • TLS 1.2 minimum for all network communications (TLS 1.3 preferred)
  • Disable TLS 1.0 and 1.1 (these are deprecated and vulnerable)
  • Require TLS for all internal communications between clinical systems (not just internet-facing traffic)
  • Encrypt HL7 v2 messages using TLS-wrapped MLLP (standard MLLP is unencrypted)
  • Enforce HTTPS for all web applications and APIs
  • Use VPN or private network connections for EHR integration traffic

Encryption Key Management

  • Rotate encryption keys annually at minimum
  • Separate key management from data storage (keys and encrypted data should not be in the same system)
  • Implement key escrow for business continuity
  • Document key management procedures and assign key custodians
  • Use cloud provider KMS for cloud-hosted data (AWS KMS, Azure Key Vault, GCP Cloud KMS)

Cloud Security for Healthcare

Cloud adoption in healthcare is accelerating, but cloud environments introduce unique security considerations.

Shared Responsibility Model

Cloud providers (AWS, Azure, GCP) secure the infrastructure. You secure the configuration, data, access controls, and applications. Most cloud security failures are configuration errors, not infrastructure vulnerabilities.

HIPAA-Eligible Cloud Configuration

  • Use only HIPAA-eligible cloud services covered under your BAA
  • Enable encryption at rest for all storage services (S3, Blob Storage, Cloud Storage)
  • Enable access logging for all storage buckets and databases
  • Configure network access controls (security groups, NSGs) with deny-by-default
  • Enable AWS CloudTrail, Azure Activity Log, or GCP Cloud Audit Logs for all API calls
  • Disable public access to storage buckets and databases by default — publicly accessible S3 buckets have caused dozens of healthcare breaches
  • Use private endpoints for database and storage access from within the cloud network
  • Enable automated backup with cross-region replication for disaster recovery

Cloud Security Monitoring

  • Deploy cloud-native security tools (AWS GuardDuty, Azure Defender, GCP Security Command Center)
  • Monitor for configuration drift — use infrastructure-as-code and automated compliance scanning
  • Alert on unusual API call patterns (bulk data downloads, permission changes, new admin accounts)
  • Monitor for unauthorized cross-account or cross-region data movement

Medical Device and IoT Security

Medical devices and IoT healthcare solutions represent one of the fastest-growing attack surfaces in healthcare.

The Medical Device Security Challenge

Connected medical devices — infusion pumps, patient monitors, MRI machines, CT scanners, ultrasound systems, blood gas analyzers, ventilators — often run embedded operating systems that are difficult or impossible to patch, use default credentials, communicate over unencrypted protocols, and were not designed with cybersecurity in mind.

Medical Device Security Best Practices

Network isolation. Place all medical devices on a dedicated, segmented network. Medical devices should not be on the same network as workstations, email servers, or internet-connected systems.

Inventory and visibility. Maintain a complete inventory of all connected medical devices including manufacturer, model, firmware version, operating system, network address, and communication protocols. You cannot secure what you do not know exists.

Passive monitoring. Deploy network traffic analysis tools that can identify and monitor medical device communications without installing agents on the devices themselves. Look for anomalous communication patterns — a medical device communicating with an external IP address it has never contacted before is a high-priority alert.

Access control. Restrict which systems can communicate with medical devices. An infusion pump should communicate with the medication management system and possibly a biomedical engineering workstation — nothing else.

Vendor management. Require medical device vendors to provide security documentation: what OS the device runs, what ports it uses, what data it transmits, what security controls are built in, and what the patching process is. Include cybersecurity requirements in medical device procurement contracts.

FDA guidance compliance. The FDA has published premarket and postmarket cybersecurity guidance for medical devices. If you are developing medical device software, these guidelines are essential.


Email and Phishing Defense

Email is the most common initial access vector for healthcare cyberattacks. Defending against email-based threats requires layered controls.

Technical Controls

  • Deploy an email security gateway with AI-based phishing detection
  • Enable DMARC, DKIM, and SPF for your email domains (prevents domain spoofing)
  • Implement URL rewriting and time-of-click analysis for links in emails
  • Sandbox and detonate email attachments before delivery
  • Block executable file types as email attachments (.exe, .js, .vbs, .ps1, .bat)
  • Enable external email tagging — prepend [EXTERNAL] to the subject line of emails from outside the organization
  • Implement data loss prevention (DLP) rules to detect PHI in outbound emails

Process Controls

  • Establish out-of-band verification procedures for financial transactions, credential changes, and vendor payment modifications
  • Never process wire transfer or payment change requests based solely on email — require phone call verification using a known number (not one provided in the email)
  • Create a clear reporting channel for suspicious emails — make it easy for staff to report phishing without fear of embarrassment

Integration and Interoperability Security

The interoperability layer — integration engines, HL7 interfaces, FHIR APIs, health information exchange connections — is a frequently overlooked attack surface in healthcare.

Integration Engine Security

Integration engines like Mirth Connect handle sensitive clinical data flowing between systems. Securing them is critical:

  • Place integration engines in a dedicated network segment
  • Restrict inbound connections to known source systems only
  • Enable TLS for all MLLP connections (HL7 v2 over MLLP is unencrypted by default)
  • Implement authentication for all API endpoints on the integration engine
  • Log all message processing activity
  • Monitor for unusual message patterns (unexpected message types, abnormal volumes, messages from unauthorized sources)
  • Keep integration engine software up to date — Mirth Connect and other engines receive security patches

FHIR API Security

  • Implement OAuth 2.0 with SMART on FHIR for all API access
  • Enforce scope-based access control — applications should only access the FHIR resources they need
  • Rate-limit API calls to prevent data harvesting
  • Log all API access with patient ID, user ID, resource type, and timestamp
  • Implement token expiration and refresh — do not issue long-lived access tokens
  • Validate all inbound data for injection attacks (SQL injection, XSS, FHIR path traversal)

Health Information Exchange Security

  • Require certificate-based authentication for all HIE connections
  • Encrypt all data in transit between your organization and the HIE
  • Implement data use agreements that specify security requirements
  • Monitor HIE query and response volumes for anomalies

Incident Response Planning

Building a Healthcare Incident Response Plan

Every healthcare organization needs a documented incident response plan specific to healthcare threat scenarios. Generic IT incident response plans are insufficient.

Incident response team roles:

  • Incident commander (typically CISO or IT director)
  • Technical lead (security engineering)
  • Clinical operations liaison (ensures patient care continuity during incident)
  • Communications lead (internal and external communications)
  • Legal counsel (regulatory notification obligations, law enforcement coordination)
  • Privacy officer (PHI exposure assessment, breach determination)
  • Executive sponsor (C-suite authority for resource allocation and decision-making)

Healthcare-Specific Incident Procedures

Ransomware response: Isolate affected systems immediately. Do NOT power off infected machines (preserves forensic evidence). Activate clinical downtime procedures. Assess which systems are affected and which are clean. Contact law enforcement (FBI, CISA). Engage a qualified incident response firm. Determine whether PHI was exfiltrated (double extortion assessment). Begin restoration from clean backups.

PHI breach response: Determine what PHI was accessed or exfiltrated. Assess the number of affected individuals. Initiate the HIPAA breach notification process (60-day deadline from discovery). Notify affected individuals, OCR, and media (for breaches affecting 500+ individuals). Document everything for regulatory and legal purposes.

Clinical system outage response: Activate clinical downtime procedures immediately. Distribute downtime forms and reference materials to clinical units. Ensure pharmacy, lab, and radiology have manual workaround procedures. Maintain communication with clinical staff on restoration timeline. Prioritize system restoration based on clinical impact (ED systems first, then inpatient, then outpatient).

Tabletop Exercises

Conduct tabletop incident response exercises at least twice per year:

  • Scenario 1: Ransomware attack during peak census
  • Scenario 2: PHI breach through a compromised business associate
  • Scenario 3: Medical device compromise affecting patient monitoring
  • Scenario 4: Insider threat — employee exfiltrating patient data

Include clinical leadership, not just IT staff, in tabletop exercises. The clinical response to a cyber incident is as important as the technical response.


Security Awareness Training

Healthcare-Specific Training Content

Generic cybersecurity training is insufficient for healthcare. Training must address healthcare-specific scenarios:

  • Recognizing phishing emails that impersonate EHR vendors, insurance companies, and regulatory bodies
  • Proper handling of PHI in email, messaging, and file sharing
  • Reporting suspicious activity without fear of punishment
  • Social engineering attacks targeting clinical staff (phone calls claiming to be from IT support requesting credentials)
  • Physical security awareness (badge tailgating, unattended workstations, visible patient information on screens)
  • Mobile device security for clinical use (securing devices between patients, not using personal devices for PHI without MDM)

Training Frequency and Methods

  • Annual comprehensive training for all staff (HIPAA requirement)
  • Monthly phishing simulations with immediate feedback for staff who click
  • Role-specific training for high-risk roles (IT administrators, billing staff, executives)
  • New hire training within first week of employment
  • Micro-training — 3–5 minute focused lessons delivered weekly or biweekly via email or internal messaging

Measuring Training Effectiveness

Track these metrics to measure whether training is working:

  • Phishing simulation click rate (target below 5%)
  • Phishing simulation reporting rate (target above 60%)
  • Time to report suspicious emails (target below 15 minutes)
  • Number of security incidents caused by human error (trend downward)
  • Training completion rate (target 100% — make it mandatory)

Vendor and Third-Party Risk Management

Healthcare organizations rely on hundreds of vendors — EHR vendors, cloud providers, billing services, IT managed service providers, software development companies, medical device manufacturers, and consultants. Each vendor with access to PHI or your network is a potential attack vector.

Vendor Security Assessment

Before granting a vendor access to PHI or your network:

  • Require SOC 2 Type II report review
  • Verify HIPAA compliance program and BAA execution
  • Request their most recent penetration test results
  • Assess their incident response capabilities
  • Review their employee background check and security training programs
  • Evaluate their subcontractor management (do they use offshore subcontractors who access PHI?)

Ongoing Vendor Monitoring

  • Review vendor SOC 2 reports annually
  • Monitor vendor breach notifications and security advisories
  • Reassess vendor security posture when contract renewals occur
  • Include security requirements and audit rights in all vendor contracts
  • Require vendors to notify you within 24 hours of any security incident affecting your data

Business Associate Agreement Requirements

Every vendor with PHI access must have a signed BAA. Beyond the standard BAA terms, consider requiring:

  • Specific encryption standards
  • Incident notification timelines shorter than 60 days (24–48 hours is best practice)
  • Right to audit the vendor’s security controls
  • Defined data return and destruction procedures at contract termination
  • Cyber insurance requirements

15. Compliance Framework Alignment

Multiple compliance frameworks apply to healthcare cybersecurity. Aligning your security program with recognized frameworks provides structure and demonstrates due diligence.

HIPAA Security Rule

The baseline regulatory requirement. Covers administrative, physical, and technical safeguards for ePHI. See our HIPAA violation penalties guide for enforcement details.

NIST Cybersecurity Framework (CSF) 2.0

The most widely adopted voluntary framework in US healthcare. Organized around six functions: Govern, Identify, Protect, Detect, Respond, Recover. HHS has published a crosswalk mapping HIPAA Security Rule requirements to NIST CSF, making it easy to demonstrate HIPAA compliance through NIST CSF implementation.

HITRUST CSF

A healthcare-specific certifiable framework that harmonizes HIPAA, NIST, PCI DSS, and other standards. HITRUST certification is increasingly required by health plans and large health systems for their business associates.

CIS Controls

The Center for Internet Security (CIS) Controls provide a prioritized set of 18 security controls. CIS Controls are actionable and prioritized — a good starting point for healthcare organizations building a security program from scratch.

NIST 800-66

NIST Special Publication 800-66 provides specific guidance for implementing the HIPAA Security Rule. It maps each HIPAA requirement to specific technical controls and implementation guidance.

Frequently Asked Questions

What is the biggest cybersecurity threat to healthcare in 2026?

Ransomware. It causes the most operational disruption, the highest financial impact, and the greatest risk to patient safety. Defending against ransomware requires a combination of email security (to block initial access), network segmentation (to limit lateral movement), endpoint detection (to catch execution), backup integrity (to enable recovery without paying ransom), and incident response planning (to minimize downtime).

How much should a healthcare organization spend on cybersecurity?

Industry benchmarks suggest 6–10% of the total IT budget for cybersecurity. Organizations that have experienced a breach typically increase this to 10–15%. For a healthcare organization with a $10 million IT budget, this means $600,000–$1.5 million annually for cybersecurity. This includes personnel, tools, training, assessments, and managed security services.

Is HIPAA compliance enough for cybersecurity?

No. HIPAA provides a regulatory floor, not a ceiling. HIPAA requirements are intentionally flexible and technology-agnostic, which means they do not prescribe specific security controls. Organizations that are “HIPAA compliant” on paper may still have significant security gaps. Use HIPAA as the baseline and supplement with NIST CSF, CIS Controls, or HITRUST for a more comprehensive security posture.

Do small practices need the same cybersecurity as large hospitals?

The threat is proportional but the security controls should scale to the organization’s size and risk. Small practices are frequently targeted because they have weaker defenses. At minimum, small practices need MFA, encryption, endpoint protection, email security, backup and recovery, security awareness training, and a basic incident response plan. Managed security service providers (MSSPs) can provide enterprise-grade security at a cost appropriate for small practices.

What should we do immediately after discovering a breach?

Contain the incident (isolate affected systems), preserve evidence (do not wipe or rebuild systems before forensic analysis), activate your incident response team, engage legal counsel and a qualified forensic investigation firm, assess the scope of PHI exposure, and begin the HIPAA breach notification process. Do not communicate publicly until you understand the scope and have consulted legal counsel.

How do we secure legacy systems that cannot be patched?

Network isolation is the primary control. Place legacy systems on dedicated network segments with strict firewall rules allowing only necessary traffic. Monitor all traffic to and from legacy systems. Implement compensating controls: host-based firewalls, application whitelisting, enhanced logging, and network-based intrusion detection. Plan and budget for system modernization to replace legacy systems within a defined timeline.

Should we pay a ransomware ransom?

Law enforcement agencies (FBI, CISA) strongly advise against paying ransoms. Payment does not guarantee data recovery, funds criminal enterprises, and marks your organization as a willing payer for future attacks. However, this is a business decision with significant nuance — organizations facing imminent patient safety risks or permanent data loss may conclude that paying is the least harmful option. Consult legal counsel and law enforcement before making this decision.
