Cybersecurity - Security Architecture and DesignWhy might network segmentation fail to prevent lateral movement by attackers inside a network?ABecause segmentation automatically blocks all trafficBBecause segmentation merges all devices into one networkCBecause segmentation replaces the need for antivirusDIf segmentation policies are poorly configured or too permissiveCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand lateral movement and segmentationLateral movement is when attackers move inside a network; segmentation limits this by isolating segments.Step 2: Identify why segmentation might failIf segmentation rules are weak or misconfigured, attackers can bypass restrictions and move laterally.Final Answer:If segmentation policies are poorly configured or too permissive -> Option DQuick Check:Segmentation fails if policies are weak [OK]Quick Trick: Strong policies needed; weak rules let attackers move [OK]Common Mistakes:MISTAKESThinking segmentation blocks all traffic automaticallyAssuming segmentation replaces antivirusBelieving segmentation merges devices
