Confidentiality
Confidentiality is a core principle of information security that ensures sensitive data is accessible only to authorized individuals, systems, or processes. It involves protecting information from unauthorized disclosure, often through encryption, access controls, and secure communication protocols. In software development, confidentiality is critical for safeguarding user data, intellectual property, and other private information.
Developers should prioritize confidentiality when building applications that handle sensitive data, such as financial systems, healthcare software, or any service with personal user information. It is essential for compliance with regulations like GDPR, HIPAA, or PCI-DSS, and for maintaining user trust by preventing data breaches and leaks. Implementing confidentiality measures helps protect against threats like eavesdropping, unauthorized access, and data theft.
