This concept refers to the separation of different parts of a network to control and limit access between them, especially in environments where sensitive or critical systems\u2014such as industrial control systems (ICS), SCADA systems, or operational technology (OT)\u2014are in use.<\/p>\n\n\n\n<p>A <strong>network enclave<\/strong> is a distinct network area with specific security controls that is isolated or segmented from other parts of the network. The <strong>Control Environment (CE)<\/strong> typically hosts mission-critical systems used for automation, control, or monitoring of physical processes (e.g., in manufacturing, energy, or utility sectors). Because these systems are highly sensitive to disruptions, segmentation is vital to reduce the attack surface and protect their integrity.<\/p>\n\n\n\n<p><strong>Network segmentation<\/strong> improves security in several key ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It <strong>limits lateral movement<\/strong> of threats within the network, meaning that if an attacker compromises one part of the network, they cannot easily reach the control systems.<\/li>\n\n\n\n<li>It <strong>enables enforcement of strict access control policies<\/strong>, allowing only authorized devices or users to communicate with the CE enclave.<\/li>\n\n\n\n<li>It supports <strong>regulatory compliance<\/strong> with standards like NIST, NERC CIP, or ISA\/IEC 62443, which require segmentation of critical networks.<\/li>\n\n\n\n<li>It reduces the potential for malware from corporate or public networks to reach sensitive operational systems.<\/li>\n<\/ul>\n\n\n\n<p>While other practices like <strong>least privilege access<\/strong>, <strong>prohibiting external media<\/strong>, and <strong>anti-virus protection<\/strong> are important and often used within a CE environment, they are <strong>not unique<\/strong> to the CE enclave. Segmentation is the most defining security control for this kind of network setup, as it directly addresses the <strong>need to isolate critical control systems<\/strong> from less secure or more exposed network segments.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What security practice BEST describes the CE network enclave?
