But with digital transformation and the advent of Industry 4.0, the old, siloed approach is showing its age.<sup>1<\/sup> The rise of manufacturing execution systems has enabled more \u201csmart factories\u201d to deliver improved manageability and data collection. While increased OT connectivity in energy production, utilities, transportation, and other critical industries help drive greater efficiency, it also creates new vulnerabilities. Roughly 41.6 billion devices are projected to be internet-facing by 2025, creating an enormous attack surface.<sup>2<\/sup> And unlike IT environments, a breach in OT can have potentially life-threatening consequences, as evidenced by the 2021 cyberattack against a Florida city\u2019s water supply.<sup>3<\/sup><\/p>\n\n\n\n<p>It is with great pleasure that we announce the general availability (GA) of the <a href=\"https:\/\/www.microsoft.com\/security\/business\/endpoint-security\/microsoft-defender-iot\"><strong>Microsoft Defender for IoT<\/strong><\/a> cloud-managed platform, which lets businesses interconnect their OT environment without compromising security. Powered by Microsoft\u2019s scalable, cost-effective cloud technology, Defender for IoT helps you manage assets, track emerging threats, and control risks across enterprise and mission-critical networks\u2014both in connected and air-gapped environments. In this blog, we\u2019ll look at today\u2019s connected OT environment, including the advantages of cloud-managed security and how a converged security operations center (SOC) can offer advantages over the traditional siloed approach.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why choose a cloud-powered solution for IoT and OT security?<\/h2>\n\n\n\n<p>The proliferation of connected devices\u2014everything from manufacturing systems, heating, ventilation, and air conditioning (HVAC), and building management systems (BMS) to heavy machinery for mining, drilling, and transportation\u2014means that OT security solutions require speed, accuracy, and context on a massive scale. In the December 2022 issue of our <a href=\"https:\/\/www.microsoft.com\/security\/business\/security-insider\/cyber-signals-1\/the-convergence-of-it-and-ot\/\">Cyber Signals<\/a> threat brief, Microsoft identified unpatched, high-severity vulnerabilities in 75 percent of the most common industrial controllers used in our customers\u2019 OT networks. Even using ordinary Internet of Things (IoT) devices like printers and routers, attackers can breach and move laterally through an IT system, installing malware and stealing sensitive intellectual property. Cloud-powered IoT and OT security solutions offer several advantages over traditional solutions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Discovery of assets end-to-end<\/strong>: Asset profiling involves analyzing network signals to discover and categorize network assets, the information collected about those assets, and the types of assets they represent. Profiling in the cloud is driven by an extensive collection of classifiers, allowing for high-fidelity categorization into categories such as servers, workstations, mobile devices, and IoT devices. Monitoring and analyzing potential security risks can be done once the assets have been classified properly. This is critical for protecting an organization&#8217;s networks, as vulnerabilities or misconfigurations in any asset can create a potential entry point for attackers. By identifying and mitigating these risks, organizations can ensure that their infrastructure is secure and protects sensitive information.<\/li>\n\n\n\n<li><strong>Detect and respond to threats as they occur in real-time<\/strong>: Reduce response times from days to minutes by detecting and responding to threats as they occur. Through collaboration between defenders from different industries, we can share best practices and information to better protect against emerging threats. By leveraging collective knowledge, defenders can stay ahead of malicious actors and respond to incidents as they occur. As a result, a cloud-powered OT solution can help prevent breaches and minimize their effects. For instance, by detecting malicious activity on a network or a suspicious login attempt, security analysts can respond immediately to prevent a breach or limit its extent.<\/li>\n\n\n\n<li><strong>Defend against known and unknown threats<\/strong>:<strong> <\/strong>Microsoft AI and machine learning alerts provide real-time detection of threats, as well as automated responses to known or unknown attacks. These alerts are designed to help security teams quickly identify and investigate suspicious activity, then take the necessary steps to protect the organization. For instance, a security system that monitors network activity in real-time can detect suspicious activity within minutes of it occurring, alerting security administrators to take action before the attack has a chance to succeed.&nbsp;<\/li>\n\n\n\n<li><strong>Compliance reports tailored to your requirements<\/strong>: Organizations can easily create and manage tailored compliance reports that are up-to-date, secure, and compliant with industry standards. With customizable reporting tools available in <a href=\"https:\/\/azure.microsoft.com\" target=\"_blank\" rel=\"noreferrer noopener\">Microsoft Azure<\/a>, users can obtain data from multiple sources and build robust, customized reports. Along with providing automated reporting and scheduling capabilities, Azure Workbooks provide a collaborative experience across silos.<\/li>\n\n\n\n<li><strong>Workflows and integrations that leverage the cloud<\/strong>: Cloud-to-cloud integrations help organizations streamline workflows and easily access data from multiple sources. By connecting multiple cloud services, organizations can gain better visibility into their operations, automate processes, and reduce manual labor. Additionally, cloud-to-cloud integrations help organizations scale quickly and eliminate the need to purchase additional hardware and software. As a result, organizations can reduce costs and increase efficiency.<\/li>\n<\/ul>\n\n\n\n<p>With any type of OT security, <strong>mean time to recovery (MTTR)<\/strong> provides a critical metric. A target MTTR for IT is typically between 30 minutes and two hours. However, because IoT and OT security often involves cyber physical systems used in utilities, healthcare, or energy production, every minute counts. Cloud-based OT security can make a difference by enabling real-time response rates across multiple locations. But what if you could take your security a step further by enabling a faster MTTR through a unified SOC for both IT and OT?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Unifying security efforts with a converged IT, IoT, and OT SOC<\/h2>\n\n\n\n<p>Empowering OT and IT security teams to work together helps create a unified front against evolving threats, maximizing your resources while gaining a comprehensive view of vulnerabilities. This way, a converged SOC taps into the strengths of both teams, creating a streamlined, cost-effective approach to enterprise security. By establishing common goals and key performance indicators, IT and OT security teams can work together on tabletop exercises to build cohesion.
