17. Data Integrity Policy#

WayToHealth takes data integrity very seriously. As stewards and partners of WayToHealth Customers, we strive to assure data is protected from unauthorized access and that it is available when needed. The following policies drive many of our procedures and technical settings in support of the WayToHealth mission of data protection.

Production systems that create, receive, store, or transmit Customer data (hereafter "Production Systems") must follow the guidelines described in this section.

17.1 Applicable Standards#

17.1.1 Applicable Standards from the HITRUST Common Security Framework#

  • 10.b - Input Data Validation

17.1.2 Applicable Standards from the HIPAA Security Rule#

  • 164.308(a)(8) - Evaluation

17.2 Disabling Non-Essential Services#

  1. All Production Systems must disable services that are not required to achieve the business purpose or function of the system.

17.3 Monitoring Log-in Attempts#

  1. All access to Production Systems must be logged. This is done following the WayToHealth Auditing Policy.

17.4 Prevention of Malware on Production Systems#

  1. All Production Systems are to only be used for WayToHealth functional needs.

17.5 Patch Management#

  1. Software patches and updates will be applied to all systems in a timely manner. In the case of routine updates, they will be applied after thorough testing. In the case of updates to correct known vulnerabilities, priority will be given to testing to speed the time to production. Critical security patches are applied within 30 days from testing and all security patches are applied within 90 days after testing.

17.6 Intrusion Prevention and Vulnerability Scanning#

  1. Production systems are monitored using IPS systems. Suspicious activity is logged and alerts are generated.
  2. Vulnerability scanning of Production Systems occurs continually. Currently, four (4) times a day. Scans are reviewed by Security Officer or designated personnel, with defined steps for risk mitigation at least quarterly, and retained for future reference.

17.7 Production System Security#

  1. System, network, and server security is managed and maintained by the Security Officer or designated personnel, in conjunction with the Engineering team.
  2. Up to date system lists and architecture diagrams are kept for all production environments.
  3. Access to Production Systems is controlled using centralized tools and two-factor authentication, where possible.

17.8 Production Data Security#

  1. Reduce the risk of compromise of Production Data.
  2. Implement and/or review controls designed to protect Production Data from improper alteration or destruction.
  3. Ensure that confidential data is stored in a manner that supports user access logs and automated monitoring for potential security incidents.
  4. Ensure WayToHealth Customer Production Data is segmented and only accessible to Customers authorized to access data.
  5. All Production Data at rest is stored on encrypted volumes using encryption keys managed by WayToHealth. Encryption at rest is ensured through the use of automated deployment scripts referenced in the Configuration Management Policy.
  6. Volume encryption keys and machines that generate volume encryption keys are protected from unauthorized access. Volume encryption key material is protected with access controls such that the key material is only accessible by privileged accounts.
  7. Encrypted volumes use AES encryption with a minimum of 256-bit keys, or keys and ciphers of equivalent or higher cryptographic strength.

17.9 Transmission Security#

  1. All data transmission is encrypted end to end using encryption keys managed by WayToHealth. Encryption is not terminated at the network end point, and is carried through to the application.
  2. Transmission encryption keys and machines that generate keys are protected from unauthorized access. Transmission encryption key material is protected with access controls such that the key material is only accessible by privileged accounts.
  3. Transmission encryption keys use a minimum of 2048-bit RSA keys, or keys and ciphers of equivalent or higher cryptographic strength (e.g., 256-bit AES session keys in the case of IPsec encryption).
  4. Transmission encryption keys are limited to use for one year and then must be regenerated.
  5. In the case of WayToHealth provided APIs, provide mechanisms to assure person sending or receiving data is authorized to send and save data.
  6. System logs of all transmissions of Production Data access. These logs must be available for audit.
