How to secure patient data in healthcare: best practices for clinics and hospitals
Seven best practices for protecting patient data in Montana clinics and hospitals, from access control and encryption to monitoring and incident response.
By Big Sky Support

Unlike a password or a credit card, patient data can't be reset.
Monday mornings in Montana healthcare are busy enough. When your EHR stalls, the waiting room backs up, and error messages start replacing lab results, you aren't thinking about frameworks or regulations. You're thinking about patients.
Unfortunately, that's also when many organizations discover their patient data security plan was more of a wish list than a working program. Healthcare has the highest average breach costs of any industry, a growing share of attacks involve ransomware and data theft, and regulators increasingly expect proof that you're doing more than the minimum.
This guide turns that reality into a clear, repeatable playbook.
The threat to patient data
Patient data is uniquely valuable. It can fuel long-term identity theft, insurance fraud, and targeted scams, and unlike a password or credit card, it can't be reset.
Healthcare environments are also uniquely exposed, with complex ecosystems of EHRs, portals, imaging, and third-party vendors; remote work, telehealth, and cloud migrations; and legacy medical devices that are hard to patch or isolate.
Healthcare breaches keep rising in frequency and impact, hacking and ransomware are involved in the majority of large incidents, and many cause extended downtime along with serious financial and reputational damage. For Montana providers, especially rural and regional clinics, that combination makes deliberate patient data security non-optional.
Best practices for securing patient data
Think of these as the core moves in a playbook, not a menu. A strong program eventually includes all of them, tuned to your size and risk.
1. Know where every patient record lives
You can't protect what you haven't found. Start with a focused risk assessment that:
- Maps every system that touches PHI: EHR, practice management, imaging, lab systems, portals, email, cloud storage, mobile devices, and medical devices.
- Identifies your crown jewels, like EHR databases, imaging archives, and critical interfaces.
- Documents the business associates and vendors that handle PHI on your behalf.
- Evaluates current safeguards against HIPAA and frameworks like HHS's healthcare Cybersecurity Performance Goals.
The result should be a current picture of risk that clinical and executive leaders can understand and act on.
2. Control who can see what, and when
Access control is where many breaches begin and end.
- Use role-based access so clinicians, billing, and front desk staff only see what they need, and avoid everyone-is-an-admin shortcuts.
- Require multifactor authentication for every account that accesses ePHI, especially EHR, email, VPN, remote access, and administrator interfaces.
- Review access regularly to remove unused accounts and adjust roles, and watch for unusual logins, like impossible travel, after-hours access, or repeated failed attempts.
These steps sharply reduce the chance that stolen credentials or insider misuse turn into a large-scale compromise.
3. Encrypt everywhere
Assume that at some point, stored or transmitted data will be exposed. Encryption is how you make that exposure far less damaging.
- Data at rest: disk and database encryption for servers, workstations, laptops, and backups that hold PHI.
- Data in transit: strong TLS for all internal and external communications, including portals, APIs, VPNs, and remote sessions.
- Key management: protect encryption keys with proper storage and access controls, so attackers can't grab the keys along with the data.
Encryption is also moving from optional to expected. HHS's proposed Security Rule update would make it a required safeguard rather than an addressable one, though that rule hasn't been finalized.
4. Turn your staff into a real security control
Most incidents still start with a person: a clicked link, a rushed reply, a misdirected email. Go beyond once-a-year training by:
- Delivering short, frequent, role-specific training built around real clinical scenarios, like EHR messages, clearinghouse notices, fax and email mix-ups, and telehealth.
- Running phishing simulations tailored to healthcare workflows, followed by in-the-moment coaching instead of blame.
- Teaching clear behaviors: how to verify requests, how to handle PHI on mobile or shared devices, and how to escalate anything suspicious quickly.
Over time, staff start to see themselves as part of the defense, not just potential victims.
5. Segment networks and manage medical devices
Flat networks and unmanaged devices are a gift to attackers.
- Separate guest Wi-Fi, administrative networks, and clinical systems into distinct segments.
- Put medical devices, especially legacy or unpatchable ones, in tightly controlled network zones with limited access in and out.
- Monitor those segments for unusual activity, like devices contacting unfamiliar external addresses or unexpected data flows.
For older devices that can't be updated, segmentation and strict access rules act as a virtual shield.
6. Monitor continuously, not once a year
Attackers move too fast for annual checkups. A modern environment includes:
- Centralized logging and security monitoring across authentication, EHR, VPN, firewalls, endpoints, and cloud platforms.
- Regular vulnerability scanning, usually monthly or quarterly, to find and fix known weaknesses.
- Periodic penetration testing, especially for internet-facing systems and high-value internal segments.
That's how you catch misconfigurations, exposed systems, and early signs of intrusion before they become headline incidents.
7. Assume incidents will happen, and rehearse
No program can promise "never." What matters is how you respond. Build and test an incident response plan that covers:
- Roles and responsibilities: who leads, who communicates with staff, patients, regulators, and media, and how decisions get made.
- Technical containment: how you isolate affected systems, preserve evidence, and keep care running safely during the event.
- Notification workflows: how you determine whether PHI was compromised and meet breach notification deadlines under HIPAA, state law, and contracts.
Pair the plan with tested 3-2-1 backups, so paying a ransom to get back to work is never on the table.
How we help clinics and hospitals protect PHI
Big Sky Cybersecurity is Montana's healthcare cybersecurity crisis response specialist. We don't just install tools. We help you build a program that holds up on your worst days, in three ways.
For the long term
24/7 security monitoring and alert triage across key systems, managed patching, hardening, and configuration, and healthcare-focused managed IT that builds security and HIPAA in from the start. Security becomes a routine part of operations instead of a project.
Before a breach
HIPAA Security Risk Analyses that show real risk and priorities, architecture reviews and segmentation plans for networks, devices, and cloud, penetration testing and vulnerability assessments built around clinical realities, and support for projects like SIEM deployments, MFA rollouts, and secure cloud migrations. The goal is closing the biggest gaps before an incident forces the issue.
During and after a crisis
Incident response and digital forensics to contain threats and determine what data and systems were affected, guidance on notification, documentation, and working with OCR and state regulators, and post-incident hardening so the same scenario is less likely to happen again.
We're there when prevention fails, not just when things are calm.
Common questions
Short answers to the questions we hear most about this topic.
Does a small or rural healthcare facility face the same data security risks?
Yes. Rural and regional organizations use many of the same EHRs, portals, and clearinghouses as large health systems, with fewer internal security resources, and attackers increasingly target them as softer entry points. Attackers care about your data and connections, not your ZIP code.
Is HIPAA compliance enough to keep patient data safe?
It's necessary, but not sufficient. Many organizations that suffered major breaches had HIPAA programs on paper. Current guidance, and HHS's proposed Security Rule changes, push toward more specific, continuous safeguards like MFA, encryption, monitoring, and testing.
Think of HIPAA as the floor, not the ceiling.
If our practice can only start with scanning or penetration testing, which should it be?
Start with vulnerability scanning plus remediation. It costs less, reduces a broad range of known risks quickly, and builds the data and processes you need for HIPAA documentation and smarter penetration testing later.
Penetration testing becomes the right move once that foundation is in place and you want to see how well it holds up.
How often should we train staff on phishing?
Train during onboarding, run simulated phishing several times a year, keep at least quarterly touchpoints, and send quick refreshers after notable incidents or new scam patterns. Short, frequent, relevant training beats one long annual session.
What's the first step if we don't know where our patient data security stands?
A focused assessment of your patient data environment. Map where PHI lives and how it moves, review your current controls and incident readiness, and identify five to ten high-impact improvements you can make over the next six to twelve months. From there, you can decide what to handle internally and where a specialist should be involved.
