The Cybersecurity and Infrastructure Security Agency (CISA) has published the Internet Exposure Reduction Guidance to help organizations identify and reduce vulnerabilities stemming from internet-exposed assets. Many organizations unknowingly leave systems—such as industrial control systems, supervisory control and data acquisition (SCADA) systems, and IoT devices—accessible online due to misconfigurations, default credentials, or outdated software. These exposures significantly increase the risk of cyberattacks and operational disruptions. The guidance outlines key steps to mitigate these risks, including assessing which assets are publicly accessible, determining the necessity of their exposure, and implementing strong security controls for those that must remain online. CISA also stresses the importance of evaluating each exposed service based on operational necessity, business justification, and existing security measures.
