Understanding ICS Procurement in the Face of Cybersecurity Threats
The rise in cybersecurity threats is reshaping how organizations procure Industrial Control Systems (ICS). These systems are crucial for the operation of critical infrastructure like power plants and water supply networks. Asset owners and operators now prioritize security as the main criterion when choosing vendors and products.
Importance of Vendor Transparency
Asset owners and operators are demanding more from vendors, particularly regarding transparency. They want detailed information on the security of both software and hardware components, including inputs from third-party suppliers. This means vendors need to ensure their supply chains are secure and all partners are vetted thoroughly. For example, just like how you might check where your food ingredients come from to ensure quality, asset owners want assurance about the components in their systems.
Training and Collaboration
Organizations are urged to provide training for installing and maintaining ICS products securely. This includes clear documentation on security features and working closely with asset owners to develop cybersecurity strategies. By collaborating, both parties can stay updated with evolving security standards and regulations. Think of it like a team sport where everyone needs to know the rules and work together to win.
Vendor Responsibilities
Vendors are expected to offer products with features like real-time threat detection and timely security updates. In 2024, the focus will shift from merely functional products to proactive collaboration against cyber threats. This means vendors will need to be more involved in protecting the systems from potential attacks, ensuring their solutions are not the weakest link in the security chain.
Evolving Priorities in Cybersecurity
Over the last two years, the focus on cybersecurity in ICS procurement has grown due to incidents like the SolarWinds attack. Asset owners emphasize comprehensive security throughout a product's lifecycle, including safe development and continuous monitoring. This approach helps protect against breaches and ensures compliance with industry standards.
Regulations and Compliance
New regulations are impacting how ICS procurement is handled. Organizations must assess vendors’ adherence to these regulations and prioritize security in their evaluation criteria. Investing in third-party risk management solutions can provide ongoing vendor security assessments. It’s similar to how you might choose a trustworthy babysitter by checking their references and track record.
Secure Development Practices
Vendors are adopting secure development practices, such as those outlined in the IEC 62443-4-1 standard, and conducting regular vulnerability testing. This helps reduce risks by minimizing vulnerabilities in the ICS equipment being procured.
Collaboration for Enhanced Security
Effective collaboration between asset owners and vendors is key to enhancing supply chain security. By setting high-security demands, sharing threat information, and aligning on standards, they can significantly improve the security posture. Joint incident response plans and security certifications can further strengthen this collaboration, much like having a neighborhood watch program to keep a community safe.
Integrating Cybersecurity into Procurement
To combat emerging threats, organizations should integrate cybersecurity from the start of the procurement process. This includes sharing threat intelligence, conducting regular audits, and investing in technologies for threat detection. Regularly updating procurement policies based on best practices can help protect ICS systems.
Continuous Updates and Patches
Manufacturers should update devices regularly, potentially every three months, or issue immediate patches for urgent issues. This proactive approach helps protect against vulnerabilities, ensuring that systems remain secure against ever-evolving cyber threats.
