Network Security — CompTIA Security+ (SY0-701) Practice Questions

Network security covers the tools, configurations, and protocols used to protect the confidentiality, integrity, and availability of data as it moves across wired and wireless networks. On the SY0-701 exam, candidates must understand firewall rules, network segmentation, VLANs, VPNs, and secure network architecture principles. Topics also include common network-based attack vectors such as packet sniffing, man-in-the-middle interception, and denial-of-service techniques. Mastery of this domain is essential because a large portion of real-world breaches exploit misconfigured or unprotected network infrastructure.
