Doors, barriers, fences, and video surveillance systems have been the most used mechanisms. <\/li>\n<li> <strong>\u201cSafety\u201d as opposed to \u201csecurity\u201d<\/strong>: the safety and integrity of people have been prioritized in possible accidents over the logical protection of communications.<\/li>\n<li><strong>\u201cSecurity by obscurity\u201d<\/strong>: industrial networks have remained isolated from the outside for many years and have been created for a very particular purpose (field buses, for example).<\/li>\n<\/ul>\n<p>The <strong>TCP\/IP, Ethernet, and Internet<\/strong> protocol has changed everything. They have opened the industrial world to <strong>interconnected networks<\/strong>, enabled remote control and governance, and computing in general enables in-depth data analysis to automatically improve productivity\/quality rates. This is where standards play an important role, as they help us consider what measures we should take to stay safe in these new scenarios.  <\/p>\n<h2><\/h2>\n<h2><strong>Relevant example for the energy sector: ISO\/IEC 27019:2017<\/strong><\/h2>\n<p>The <strong>IEC 27019:2017 standard<\/strong> comes from IEC 27002, adding a series of specific controls for electrical control systems. The objective is to extend the <strong>ISO\/IEC 27000 series<\/strong> to the domain of automation processes in the energy sector. Specifically, it includes:  <\/p>\n<p>\u2022 <strong>Control of central processes<\/strong> and distributed processes, monitoring and automation of processes, as well as information systems used for their operation, such as programming and parameterization devices.<br \/>\n<strong>\u2022 Automation components<\/strong> such as PLCs, digital sensors, and actuator elements.<br \/>\n<strong>\u2022 Other support systems<\/strong> used in process control, for example, data visualization, tracking, historical recording, report generation, etc.<br \/>\n<strong>\u2022 Communication technologies<\/strong> used in process control: networks, telemetry, remote control applications, and remote control technology.<br \/>\n<strong>\u2022 Infrastructure components<\/strong> for advanced metering (AMI) such as smart meters<br \/>\n\u2022 Measurement devices.<br \/>\n<strong>\u2022 Digital protection and security systems<\/strong> such as protection relays, safety PLCs, etc.<br \/>\n\u2022<strong> Energy management systems<\/strong>.<br \/>\n<strong>\u2022 Software and Firmware<\/strong> of the applications installed in the systems mentioned above.<br \/>\n\u2022 Any premises that house the aforementioned equipment and systems.<br \/>\n<strong>\u2022 <\/strong><strong>Remote maintenance<\/strong> systems for the mentioned systems.<\/p>\n<h2><\/h2>\n<h2><strong>Relevant example for information security: ISO\/IEC 15408-1:2009<\/strong><\/h2>\n<p>The <strong>IEC 15408 standard<\/strong> is focused on the product and not so much on the process. It establishes the general concepts and principles for the evaluation of IT products. It specifies a general model for evaluating the security properties of these products, whether hardware, firmware, or software.  <\/p>\n<p>The result of this evaluation can help consumers choose those products that meet the necessary <strong>security requirements<\/strong> for their purposes and provide confidence in their operation.<\/p>\n<p>The <strong>result of the evaluation<\/strong> usually classifies the products into the following CC (Common Criteria) levels:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-29157 aligncenter\" src=\"https:\/\/becolve.com\/wp-content\/uploads\/2023\/04\/niveles-CC.png\" alt=\"Common Criteria levels table\" width=\"694\" height=\"316\"><\/p>\n<h2><\/h2>\n<h2><strong>Relevant Example for Industrial Automation: ISA\/IEC 62443<\/strong><\/h2>\n<p>The <strong>ISA\/IEC 62443<\/strong>, a benchmark in the cybersecurity of the industrial world, includes a set of standards that focus on evaluating security in ICS\/OT in 4 categories: <\/p>\n<p><strong>\u2022 General<\/strong>: general concepts, models, and terminologies where reference architectures are defined in OT environments.<br \/>\n\u2022<strong> Policies and procedures:<\/strong> establishes the program for cybersecurity management, patch management, and supplier management to maintain high levels of protection as time passes and technologies and threats change.<br \/>\n<strong>\u2022 System<\/strong>: establish guidelines for risk assessment, security requirements, and technologies we have at our disposal to increase the level of protection.<br \/>\n<strong>\u2022 Components<\/strong>: describes the requirements for designing products and subcomponents securely.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-29159 aligncenter\" src=\"https:\/\/becolve.com\/wp-content\/uploads\/2023\/04\/tabla-componentes.jpg\" alt=\"ISA\/IEC 62443 components table\" width=\"800\" height=\"537\"><\/p>\n<h2><\/h2>\n<h2><strong>Conclusions<\/strong><\/h2>\n<p>The <strong>standards are not static<\/strong>, they are in continuous development and refinement to adapt to the reality of the moment. They can be very useful for: <\/p>\n<p>\u2022<strong> Protecting<\/strong> the productive assets of our companies.<br \/>\n\u2022 The recommendations that arise from these standards will soon be considered as <strong>minimum requirements to be met<\/strong>, to keep cybersecurity risks low.<br \/>\n<strong>\u2022 The preliminary work<\/strong> of implementation helps to consider the
