3、 20243Executive SummaryPerimeter security alone is no longer sufficient for securing critical infrastructure due to evolving threats,including advanced persistent threats(APTs)from sophisticated adversaries.Once inside the network,the adversary could exploit vulnerabilities to move laterally undetec

4、ted and perform reconnaissance or disrupt the network,if a monitoring system were not in place.The best way to prepare for evolving threats is to have a system aligned with a zero trust architecture(ZTA)that secures micro-perimeters across the entire mobile network and provides the ability to identi

5、fy,protect,detect,respond,and recover from evolving attacks.Industry standards define technical capabilities that support a ZTA,but these capabilities need to be complemented with automated security operations to continuously achieve the desired security posture.This whitepaper describes a security
