Study Notes

Data Security

HealthCarePlus was not compliant with HIPAA regulations
The hospital discovered data security issues
The hospital had insufficient encryption for ePHI at rest and in transit

Implementing Encryption for ePHI

Implemented LUKS to encrypt data at rest
Implemented SSL/TLS for secure communication
Used OpenSSL for encryption
Configured SSL for Apache and NGINX
Used SSH for secure internal communication

Access Control

Implemented user and group management to restrict access
Restricted access to ePHI using user roles
Implemented Sudo Access Control
Restricted root access to a limited number of users

Auditing and Monitoring

The hospital lacked proper auditing and monitoring before the implementation
Implemented auditd to track access to sensitive files
Centralized logging using syslog for compliance

Secure Backup and Disaster Recovery

The hospital did not have a backup and data recovery plan
Implemented secure backups using rsync and cron jobs
Used LUKS for secure offsite backups

Strengthening Network Security

The hospital had weak network security with insufficient firewall and VPN security
Implemented ufw to configure firewall rules
Used OpenVPN for secure remote access

Outcome

HealthCarePlus achieved HIPAA compliance
Implemented robust encryption and access control
Improved network security by implementing firewalls and VPN access
Used Linux commands such as auditd, rsync and ufw for securing sensitive patient data.
