SHG has a number of procedures for ensuring confidentiality and security. All communications with our data collection platforms are encrypted using SSL and we maintain a role based permission system to ensure individuals have only the minimum level of access required to perform their job functions.
We employ a three-tier firewalled architecture to prevent unauthorized activity within the system. The first layer of defense is a set of reverse proxy servers which protect our web servers from attacks. Our web servers and database servers also reside in their own separate firewalled networks. Finally, we employ a near real time back-up system where multiple backups are made each day. Data is also replicated offsite to support our disaster recovery capabilities.
