Designing a secure network

Designing a secure network resembles planning a city’s transportation grid transitioning to IPv6 opens up countless new “roads” for devices but also introduces fresh vulnerabilities like neighbor discovery spoofing that attackers can exploit. Guarding the global internet’s backbone, secure BGP practices—such as RPKI validation and prefix filtering serve as kind of like traffic police preventing route hijacks that could redirect entire streams of data down malicious detours. Within your own data center or cloud, micro segmentation and software defined networking carve out zero-trust zones like gated neighborhoods, isolating critical assets and stopping lateral movement should an intruder breach the perimeter.
