Securing a Healthcare Surveillance Network Fast
How We Helped a Healthcare Provider Lock Down Their Surveillance System Against Unauthorized Access
Healthcare organizations in 2025 and 2026 face growing cybersecurity pressure from every direction. While most security conversations focus on electronic health records and email threats, surveillance infrastructure has quietly become another major attack surface for healthcare providers.
At Epis Technology, we recently worked with a healthcare client that discovered serious vulnerabilities inside their surveillance environment after unusual remote login activity triggered security concerns.
What initially looked like a simple camera access issue quickly revealed broader infrastructure and network exposure risks that could have impacted both operational security and compliance requirements.
The Initial Warning Signs
The healthcare provider operated multiple surveillance cameras across:
- Patient entrances
- Parking facilities
- Medication storage areas
- Staff-only hallways
- Administrative offices
The organization began noticing:
- Unexpected camera disconnects
- Unrecognized login attempts
- Slow surveillance playback performance
- Random remote access alerts
- Unusual outbound network traffic
Because healthcare facilities handle sensitive environments and regulated operational data, even minor surveillance security concerns required immediate investigation.
The Hidden Problem
After reviewing the surveillance infrastructure, our team discovered several issues that had developed gradually over time:
- Weak remote access controls
- Outdated firmware
- Open management ports
- Shared administrative credentials
- Poor network segmentation
- Excessive user permissions
The surveillance environment had expanded over several years without a complete security redesign.
Unfortunately, this is increasingly common in 2025 and 2026 as organizations add cameras, remote access tools, and cloud integrations faster than security policies evolve.
Why Surveillance Systems Are Increasingly Targeted
Modern surveillance systems are no longer isolated camera networks.
Today’s systems often connect directly with:
- Cloud services
- Mobile applications
- Remote monitoring platforms
- Centralized storage systems
- AI analytics environments
Attackers increasingly target surveillance infrastructure because compromised camera systems can expose:
- Facility layouts
- Employee movement patterns
- Operational schedules
- Sensitive physical security information
Healthcare environments are especially attractive because operational downtime and security incidents can directly affect patient services.
Immediate Security Actions
Epis Technology immediately initiated containment and hardening procedures to reduce exposure.
We:
- Restricted remote access paths
- Closed unnecessary open ports
- Rotated administrative credentials
- Enabled stronger authentication policies
- Segmented surveillance traffic
- Audited user permissions
- Reviewed outbound traffic behaviour
These initial steps helped stabilize the environment and reduce the risk of unauthorized external access.
The Synology-Powered Infrastructure Improvements
The healthcare provider was using Synology infrastructure as part of its surveillance storage and management environment.
To improve both security and operational reliability, Epis Technology redesigned portions of the deployment to include:
- Better storage segmentation
- Snapshot-enabled surveillance protection
- Improved user access controls
- Hardened remote access workflows
- Enhanced backup protection
- Centralized monitoring improvements
This created a more resilient and manageable surveillance environment.
Strengthening Surveillance Access Controls
One of the biggest weaknesses we identified was inconsistent access management.
We implemented:
- Multi-factor authentication
- Role-based access controls
- Limited administrative privileges
- Secure remote access policies
- Improved session auditing
This significantly reduced the risk of unauthorized access and credential misuse.
Protecting Surveillance Data from Ransomware
Many organizations overlook the fact that surveillance archives are also vulnerable to ransomware and storage corruption.
To improve recovery readiness, we added:
- Snapshot Replication
- Backup validation workflows
- Off-site backup integration
- Recovery testing procedures
This ensured surveillance footage remained protected even during infrastructure disruptions.
Improving Network Segmentation
Previously, portions of the surveillance system shared network paths with broader operational traffic.
We redesigned the environment to:
- Isolate surveillance VLANs
- Reduce unnecessary communication paths
- Improve internal traffic visibility
- Limit exposure between systems
Network segmentation became a major improvement in overall security posture.
Lessons Healthcare Organizations Are Learning
One of the biggest lessons healthcare providers are learning today is that surveillance systems must be treated as part of the broader cybersecurity infrastructure, not simply physical security hardware.
Organizations now need:
- Secure remote access policies
- Strong authentication controls
- Network segmentation
- Backup protection
- Firmware management
- Infrastructure monitoring
- Recovery planning
Modern surveillance systems are deeply connected to operational continuity and regulatory compliance.
