Healthcare is quickly adapting to the digital environment by leveraging web-based technologies, electronic health records (EHR) and mobile devices to facilitate the movement of information. With innovative software technology comes great responsibility. One of the unfortunate downsides to increasing the use of technology for data sharing in the healthcare world is the risk of data falling into the wrong hands. Full measures need to be put in place to protect patient’s Protected Health Information (PHI). The Health Insurance Portability and Accountability Act (HIPAA) mandates that all PHIs be secured. Any breach, if not handled appropriately under established procedures, can lead to grave consequences including heavy penalties, jail time, or both. Needless to say that proper mechanisms need to be implemented to secure data while it is stored, transmitted and consumed.
Understanding Regulatory Standards
Knowledge is power. It is paramount that software providers look for back-end development partners that have Healthcare IT experience. This includes extensive knowledge and proficiencies with federal regulations like American Recovery and Reinvestment Act (ARRA), meaningful use stage 1 and 2, Accountable Care Act, etc. Also, regulatory health information exchange (HIE) standards such as Health Level 7 (HL7), Health Information Exchange Open Source (HIEOS), Fast Healthcare Interoperability Resources (FHIR), Consolidated-Clinical Document Architecture (C-CDA), Continuity of Care (CCD/CCR) as well as clinical and financial work flows.
With information traveling over a network it may be subject to interference. Hence, it is important that data be encrypted in transit. Vendors must include encryption technology to prevent disclosure of patient health information while data is communicated between the application and the server. Web traffic must be transmitted through a secure connection using only strong security protocols such as Secure Sockets Layer (SSL) or Transport Layer Security (TLS). SSL/TLS certificates are light weight data files that are purchased and installed directly onto the server. Once implemented, a user will be able to connect to the web-based application server via a secure tether with an internet browser.
Organizations have been keen on securing networks and internal infrastructure from external threats. With this in mind, malicious entities are looking to breach data at the application level. Healthcare software proprietors must protect their application from security threats by employing hardening tactics, which shields bugs and vulnerabilities in the coding. This technique primarily includes code obfuscation. Code obfuscation is the act of intentionally creating obscure source code to make it difficult for entities to decipher. Properly employing this tactic hinders a threats ability to reverse engineer and tamper with an application to facilitate a breach.
