Retail and E-commerce Security: Protecting Payments and Customer Trust
Customers abandon brands that lose their data. Protecting payments, accounts and websites in retail and e-commerce — especially during peak trading.
Key takeaways
- Ransomware is the leading threat to healthcare availability.
- Medical devices often run legacy software and need segmentation.
- Health data is sensitive personal data with strict protection duties.
- Downtime procedures must be clinical, not just technical.
Why healthcare is targeted
Healthcare holds highly sensitive data, depends on availability and often runs legacy systems. Attackers know that pressure to restore services quickly is intense.
Key risks
- Ransomware disrupting electronic health records and imaging
- Theft of patient records
- Vulnerable connected medical devices
- Third-party access by device vendors and service providers
- Phishing of busy clinical staff
Priorities
| Area | Action |
|---|---|
| Identity | MFA for remote and privileged access; fast, secure clinical sign-on |
| Medical devices | Inventory, segmentation, vendor access control |
| Backups | Immutable backups of clinical systems; tested restores |
| Monitoring | 24x7 detection including OT-like device networks |
| Downtime procedures | Paper-based clinical continuity, rehearsed |
Data protection
Health information is special-category data under GDPR, and in the United States HIPAA applies to covered entities and business associates. Control access by role and log access to records.
Clinical engagement
Security controls succeed in healthcare when clinicians help design them. Fast sign-on, sensible session timeouts and clear downtime procedures maintain both safety and security.
Securing the clinical workflow
Security controls that slow clinicians down get bypassed. Tap-and-go authentication, single sign-on to clinical applications and role-based access aligned to care teams improve both security and efficiency. Shared workstations need fast user switching rather than shared accounts.
Third parties and device vendors
Hospitals depend on equipment manufacturers, laboratory systems, imaging providers and outsourced IT. Require vendors to use controlled remote access, disclose vulnerabilities, support patching and meet contractual security requirements. Keep an inventory of who can connect, to what, and why.
Rehearsing downtime
| Exercise | Purpose |
|---|---|
| EHR outage tabletop | Validate clinical downtime procedures and communication |
| Imaging system failover | Confirm diagnostics continue |
| Ransomware simulation | Test decision-making with executives and clinical leads |
| Restore test | Measure real recovery time of clinical systems |

Frequently asked questions
Can medical devices be patched?
Sometimes only with manufacturer approval. Segmentation and monitoring provide protection where patching is not possible.
What should a hospital do first?
Secure remote access with MFA, protect backups, and inventory and segment medical devices.
How do we test without disrupting care?
Use carefully scoped tests, maintenance windows and non-production environments where possible.
