Modernizing Data Systems in Environmental Public Health: A Blueprint for Action
Data and Cybersecurity: Protecting Information Assets Data and cybersecurity involve a set of technologies, policies, and practices designed to protect digital data from unauthorized access, corruption, or theft. Effective data modernization necessitates cybersecurity measures to safeguard sensitive public health information. Comprehensive cybersecurity frameworks— incorporating multifactor authentication (MFA), encryption protocols, routine vulnerability assessments, and regular staff cybersecurity training—strengthen organizational security. A culture of cybersecurity vigilance ensures resilience against cyber threats, protects the integrity of public health data, and maintains community trust. Example: A state environmental health agency implements MFA and role-based access controls for its complaint database, ensuring that only authorized staff can ac - cess resident-submitted health data. Annual phishing simulations and cyberse- curity training sessions also enhance the system's integrity. Cloud Computing: Infrastructure for Modernization Cloud computing is a model for delivering computing services—such as stor - age, processing, and analytics—over the internet (i.e., the cloud) rather than on local servers. This model offers scalability, flexibility, and real-time access while providing a cost-effective infrastructure for data access, storage, and analysis. Moving to cloud-based solutions allows organizations to manage large datasets efficiently, improve data interoperability, and ensure reliable system uptime. EPH professionals benefit from understanding the fundamentals of cloud computing, including service models (e.g., IaaS, PaaS, SaaS) and strategies for securely mi- grating legacy systems to cloud environments. Example: A regional air quality monitoring program transfers its historical sensor data and real-time feeds to a cloud-based platform like Amazon Web Services (AWS). This facilitates continuous uptime, enables remote data access for inspectors in the field, and promotes cross-agency collaboration free from the limitations of local servers.
Data Sharing: Enhancing Collaboration and Transparency Data sharing is the intentional and secure exchange of data between organi - zations, systems, or users to support collaboration, improve services, and en - hance public transparency, all while maintaining data privacy and control. Stra- tegic data sharing promotes collaboration, innovation, and transparency among EPH agencies and within the broader community. Effective data sharing entails clear agreements that outline data usage, privacy considerations, access con - trols, and interoperability standards. The use of secure data-sharing platforms, standardized APIs, and comprehensive metadata improves the efficiency of data exchange, enabling coordinated public health responses and stronger commu - nity engagement. Example A coastal health district signs a data-sharing agreement with a local university and wastewater treatment facility to exchange surveillance data on waterborne illnesses. Using standardized APIs, they combine environmental sampling data, illness reports, and weather information to identify and respond to contamina - tion events more quickly. Mastery of these advanced topics enables EPH professionals to navigate and leverage emerging technologies and practices, greatly enhancing their ability to address complex public health challenges.
