What are the protection measures for sensitive data during transmission?

Protection measures for sensitive data during transmission include:

1. Encryption: Use strong encryption protocols like TLS (Transport Layer Security) to scramble data, making it unreadable to unauthorized parties. For example, HTTPS encrypts web traffic between a browser and a server.

   • Example: A banking app uses TLS to secure user login credentials during transmission.

2. VPNs (Virtual Private Networks): Create a secure tunnel for data transmission over public networks.

   • Example: Remote employees access company resources via a VPN to prevent interception.

3. Secure Protocols: Replace insecure protocols (e.g., FTP, HTTP) with secure alternatives (SFTP, HTTPS).

   • Example: File transfers between servers use SFTP instead of FTP to avoid exposure.

4. Data Masking: Hide sensitive parts of data during transmission (e.g., masking credit card numbers).

   • Example: A payment gateway displays only the last four digits of a card number.

5. Tokenization: Replace sensitive data with tokens that have no intrinsic value.

   • Example: E-commerce platforms use tokenized payment processing to avoid storing card details.

6. Network Segmentation: Isolate sensitive data traffic from general network traffic.

   • Example: A healthcare provider separates patient data transmission onto a dedicated network segment.

7. Regular Audits and Monitoring: Detect anomalies or breaches in real-time.

   • Example: A company uses intrusion detection systems (IDS) to monitor data transmission logs.
