What term describes encryption of traffic to prevent eavesdropping on the network?

• A. WEP
• B. IPsec VPN
• C. HTTPS/TLS encryption
• D. Steganography

Answer: (C)

The main idea here is protecting data as it travels across the network so others can’t read it. HTTPS/TLS encryption does exactly that: it wraps the web traffic in a secure TLS channel, so the data between your browser and the server is encrypted in transit. TLS works by negotiating a secure session and then using symmetric encryption for the actual data, along with integrity checks and server authentication, which prevents eavesdroppers from understanding or tampering with what’s being sent. This makes it the best fit for describing encryption of traffic to prevent network eavesdropping in everyday web usage. WEP is outdated Wi‑Fi encryption with known flaws, Steganography hides data rather than encrypts it, and IPsec VPN encrypts traffic but is a broader VPN solution rather than the specific in-transit web encryption described here.
