Introducing security controls during the requirements phase, applying coding standards throughout the development, and performing security testing before launch represents an integrated approach to the security deployment for the patient management system. Addressing security at every stage ensures that security is built into the system from the outset, reducing the risk of later vulnerabilities. Merely encrypting the database addresses only data at rest and does not integrate security throughout the lifecycle. Restricting access to development environments protects the development process but leaves post-deployment security measures unaddressed. Updating service-level contracts is crucial for managing relationships with third parties but does not inherently secure the application development process.
