Which technology aids in securing data for online transactions?

Encryption is a fundamental technology that safeguards data during online transactions. When you conduct an online transaction, sensitive information such as credit card numbers, personal identification, and account credentials needs protection from eavesdroppers and unauthorized access. Encryption transforms this sensitive data into a code that can only be deciphered by individuals who possess the correct decryption keys.

This process ensures that even if data is intercepted while being transmitted over the internet, it will be unreadable and useless to anyone attempting to exploit it. By using encryption protocols such as TLS (Transport Layer Security) and SSL (Secure Sockets Layer), online transactions can be conducted in a secure manner, enhancing the trust of consumers and maintaining the privacy of their information.

While firewalls, virtual private networks (VPNs), and proxies all play roles in network security, they do not specifically provide the same level of data protection for transactions as encryption does. Firewalls primarily filter traffic to prevent unauthorized access, VPNs create secure tunnels for data transmission, and proxies act as intermediaries between a user and the internet. However, it is encryption that specifically ensures the confidentiality and integrity of the data being transmitted during online transactions.
