Encryption In Transit
Encryption in transit is a security practice that involves encrypting data while it is being transmitted over a network, such as the internet or internal networks. It ensures that sensitive information remains confidential and protected from interception, eavesdropping, or tampering by unauthorized parties during communication between systems, applications, or users. This is typically implemented using cryptographic protocols like TLS/SSL to secure data flows in web traffic, APIs, and other network communications.
Developers should implement encryption in transit to protect sensitive data, such as personal information, financial details, or proprietary business data, from being exposed during transmission, which is critical for compliance with regulations like GDPR, HIPAA, or PCI DSS. It is essential in scenarios like securing web applications (e.g., using HTTPS), protecting API calls in microservices architectures, and safeguarding data in cloud environments or mobile apps to prevent man-in-the-middle attacks and ensure data integrity.
