| Titre | Cybersécurité pour les systèmes de contrôle industriel: meilleures pratiques Cybersecurity for Industrial Control Systems: Best practices |
| Texte | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. Network segmentation, software patching, and continual threats monitoring are key cybersecurity best practices for Industrial Control Systems (ICS). Although ICSs significantly improve health and safety by automating dangerous tasks, facilitating remote monitoring and control, and activating safety protocols in the case of emergency, they’re increasingly exposed to cybersecurity threats. In 2022, there was a 2,000% increase in adversarial reconnaissance targeting Modbus/TCP port 502 — a widely-used industrial protocol — allowing malicious actors to exploit vulnerabilities in operational technology systems. Fortunately, by taking steps to improve and maintain ICS cybersecurity, manufacturers can successfully reduce the attack surface of their critical infrastructure and keep threats (including phishing, denial-of-service attacks, ransomware, and malware) at bay. ICS cyberattacks on the rise ICS cyberattacks are on the rise, with almost 27% of ICS systems affected by malicious objects in the second quarter of 2023, data from Kaspersky reveals. Cyberattacks have the power to devastate ICS systems, damage equipment and infrastructure, disrupt business, and endanger health and safety. For example, the U.S. government has warned of a malware strain called Pipedream: “a modular ICS attack framework that contains several components designed to give threat actors control of such systems, and either disrupt the environment or disable safety controls”. Although Pipedream has the ability to devastate industrial systems, it fortunately hasn’t yet been used to that effect. And, last year, a notorious hacking group called Predatory Sparrow launched a cyberattack on an Iranian steel manufacturer, resulting in a serious fire. In addition to causing equipment damage, the hackers caused a malfunctioning foundry to start spewing hot molten steel and fire. This breach only highlights the importance of safety protocols in the manufacturing and heavy industry sectors. By leveraging the latest safety tech and strengthening cybersecurity, safety, security, and operational efficiency can all be improved. Segment networks By separating critical systems from the internet and other non-critical systems, network segmentation plays a key role in improving ICS cybersecurity. Network segmentation is a security practice that divides a network into smaller, distinct subnetworks based on security level, functionality, or access control, for example. As a result, you can effectively prevent attacker lateral movement within your network — this is a common way hackers disguise themselves as legitimate users and their activities as expected traffic, making it hard to spot this method. Network segmentation also lets you create tailored and unique security policies and controls for each segment based on their defined profile. Each individual segment is therefore adequately protected. And, since network segmentation also provides you with increased visibility in terms of network activity, you’re also better able to spot and respond to problems with greater speed and efficiency.
