Which action should be taken to ensure that unencrypted network traffic is protected?

Rationale

Data should be transmitted using the transport layer security (TLS) protocol.

TLS is a widely accepted security protocol that provides encryption for data transmitted over a network, ensuring confidentiality and integrity. By using TLS, unencrypted network traffic can be effectively protected from eavesdropping and tampering.

A (Data should be transmitted using the secure socket layer (SSL) protocol.) YOUR ANSWER

SSL is an older protocol that preceded TLS and has known vulnerabilities. While SSL does provide encryption, it is no longer considered secure for protecting sensitive data. TLS is the modern replacement that addresses these security flaws and is recommended for secure communications.

B (Data should be transmitted after it is compressed and password protected using data gunzip (GZ).) YOUR ANSWER

While compression can reduce data size, it does not inherently provide security against interception or unauthorized access. Password protection alone is also insufficient for securing data in transit, as it does not encrypt the data. TLS is specifically designed to secure data during transmission.

C (Data should be transmitted using generic routing encapsulation (GRE).) YOUR ANSWER

GRE is a tunneling protocol used to encapsulate a wide variety of network layer protocols, but it does not provide encryption or security features. As a result, using GRE alone would leave the data exposed to potential interception. TLS is necessary to ensure that data remains secure while being transmitted.

Conclusion

To protect unencrypted network traffic, the use of the transport layer security (TLS) protocol is essential. Unlike SSL, GRE, or simple compression and password protection methods, TLS provides robust encryption and security features, safeguarding data from potential threats during transmission. By implementing TLS, organizations can significantly enhance their network security and protect sensitive information.
