facilities to guarantee correct and expected operation, an important point when industrial networks are intended to be deterministic.<\/p>\n<p>The protection mechanisms of internal networks must contemplate the <strong>following lines of fortification:<\/strong><\/p>\n<ul>\n<li><strong>Secure network architecture<\/strong> with high levels of availability, segmentation and scalability.<\/li>\n<li><strong>Network electronics<\/strong> with capabilities to control access to the network.<\/li>\n<li><strong>High monitoring of the network infrastructure<\/strong> to be able to react quickly to a network infrastructure failure.<\/li>\n<li><strong>High monitoring and profiling of network traffic<\/strong> to detect anomalous communications within the network.<\/li>\n<\/ul>\n<p>These mechanisms must be sufficiently <strong>robust to guarantee:<\/strong><\/p>\n<ol>\n<li><strong>High resilience<\/strong> to physical failures of network electronics.<\/li>\n<li><strong>High capabilities<\/strong> <strong>of intrusion detection<\/strong> or strange behavior within the network.<\/li>\n<li><strong>High fault detection capabilities<\/strong> of hardware or communication links.<\/li>\n<li>Ability to implement <strong>network access controls<\/strong>.<\/li>\n<\/ol>\n<p><img loading=\"lazy\" decoding=\"async\"

with capabilities to implement highly redundant networks with security and access control capabilities.<\/li>\n<li><strong>Data diodes<\/strong> for the segmentation of especially critical areas within ICS OT environments.<\/li>\n<li><strong>DPI Firewalls for securing<\/strong> assets that use insecure industrial protocols, such as ModBUS-TCP.<\/li>\n<li><strong>Industrial firewalls<\/strong> for the segmentation of the different industrial subzones.<\/li>\n<li><strong>Monitoring systems<\/strong> based on SNMP for infrastructure supervision.<\/li>\n<li><strong>Network traffic analysis systems<\/strong> for the creation of baseline equipment behaviors and anomaly detection.<\/li>\n<\/ul>\n<p class=\"p1\">In case of not having monitoring tools, Logitek recommends carrying out internal network audits on a periodic format to verify the correct deployment of a secure network architecture, the correct access control and that the network traffic is what it should be.<\/p>\n<p
