About this clipart
This schematic illustrates a classic network security setup where a brick-style firewall sits between a trusted local area network (LAN) on the left-comprising three client devices-and an untrusted wide area network (WAN) on the right, represented by multiple interconnected clients. Green lines denote data connections, with the firewall inspecting and controlling traffic flow to enforce security policies. The visual metaphor of a brick wall emphasizes robust protection against cyber threats.
Used in cybersecurity educational content, IT documentation, or vendor marketing pages to explain firewall functionality. Matches user intent for understanding network segmentation, perimeter defense, or preparing for certification exams like CompTIA Security+.
