Which of the following is the BEST way to defend against network sniffing?
A.
Using encryption protocols to secure network communications
B.
Register all machines MAC Address in a Centralized Database
C.
Restrict Physical Access to Server Rooms hosting Critical Servers
D.
Use Static IP Address
Explanation:
A way to protect your network traffic from being sniffed is to use encryption such as Secure Sockets Layer
(SSL) or Transport Layer Security (TLS). Encryption doesn’t prevent packet sniffers from seeing source and
destination information, but it does encrypt the data packet’s payload so that all the sniffer sees is encrypted
gibberish.
