We\u2019ll also discuss our responsible disclosure as well as the feedback we got from the vendors we evaluated.<\/p>\n<p><span class=\"body-subhead-title\">Countermeasures<\/span><\/p>\n<p>We found that only two of the four vendors analyzed support authentication. Neither of them has authentication enabled by default, which leaves the machines vulnerable to attacks by malicious users. Enabling authentication is essential for protecting Industry 4.0 features from abuse.<\/p>\n<p>Resource access control systems are important for reducing the impact of attacks. Many technologies allow access to all a controller\u2019s resources, which can be dangerous. A correct approach is to adopt resource access control systems that grant limited access. This will help to ensure that only authorized users have access to the controller\u2019s resources and that these resources are protected from unauthorized access.<\/p>\n<p>When it comes to integrators and end users, we suggest these countermeasures:<\/p>\n<ul>\n<li><span class=\"rte-red-bullet\">Context-aware industrial intrusion prevention and detection systems (IPS\/IDSs): These devices, which have recently seen a surge in popularity in the catalogues of security vendors, are equipped with network engines that can capture real-time traffic associated with industrial protocols to detect attacks.<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Network segmentation: Correct network architecting is of great importance. As our research has revealed, all the tested machines expose interfaces that could be abused by miscreants.<\/span><\/li>\n<li><span class=\"rte-red-bullet\">Correct patching: Modern CNC machines are equipped with full-fledged operating systems and complex software, which might inevitably contain security vulnerabilities. This was indeed the case with the machines that we tested.<\/span><\/li>\n<\/ul>\n<p><span class=\"body-subhead-title\">Responsible Disclosure<\/span><\/p>\n<p>We contacted the affected vendors while tackling controllers sequentially, with our first contact in November 2021 and the last one in March 2022. The Industrial Control Systems Cyber Emergency Response Team (ICS CERT) at Cybersecurity & Infrastructure Security Agency extended invaluable help during the discussion which we are grateful for.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"image\">\n<figure class=\"image-figure\"> <img decoding=\"async\" src=\"https:\/\/www.trendmicro.com\/content\/dam\/trendmicro\/global\/en\/research\/22\/l\/the-security-risks-faced-by-cnc-machines-in-industry-4-0-part-3\/responsible-disclosure-process.png\" alt=\"disclosure-process\"><figcaption>Table 1.

More importantly, all of them have expressed interest in our research and have decided to improve either their documentation or their communication efforts with their machine manufacturers, with the final effort of offering end users more secure solutions.<\/p>\n<p>To learn more about the security risks faced by CNC machines, <a
