But not enough to escape a trained defender’s eye.In Episode 10 of CyberLex Blue Team Academy, you investigate a rogue device incident and uncover the techniques attackers use to bypass identity controls and gain physical footholds inside corporate networks. This episode teaches network intuition, rogue device detection, lateral movement awareness, and rapid containment strategy.What you’ll learn: • How rogue devices appear in network logs • Why naming conventions and MAC patterns matter • How stealth scanning works in low and slow patterns • How attackers use physical access to bypass identity • How to analyze ARP, DHCP, and switch-port logs • How to detect C2 callbacks from unauthorized hosts • Proper containment: isolate, trace, confiscate, imageIdeal for: • Security+ learners studying network fundamentals • CC students mastering basic network security • CySA+ students honing detection and correlation • CCSP learners understanding network + cloud interplay • SOC analysts, blue teamers, IT pros, physical security teams • Anyone building “network intuition” as a defender Some threats walk in quietlythrough the front door.Your awareness keeps them out.Listen to Episode 10 now — The Device That Didn’t Belong on the Network.Your network instincts strengthen here.
