AI Techniques For Securing Critical Infrastructure

The Cyber Security Agency of Singapore (CSA) has published “Guidelines on Securing AI Systems,” to help system owners manage security risks in the use of AI throughout the five stages of the AI lifecycle. 1. Planning and Design: - Raise awareness and competency on security by providing training and guidance on the security risks of #AI to all personnel, including developers, system owners and senior leaders. - Conduct a #riskassessment and supplement it by continuous monitoring and a strong feedback loop. 2. Development: - Secure the #supplychain (training data, models, APIs, software libraries) - Ensure that suppliers appropriately manage risks by adhering to #security policies or internationally recognized standards. - Consider security benefits and trade-offs such as complexity, explainability, interpretability, and sensitivity of training data when selecting the appropriate model to use (#machinelearning, deep learning, #GenAI). - Identify, track and protect AI-related assets, including models, #data, prompts, logs and assessments. - Secure the #artificialintelligence development environment by applying standard infrastructure security principles like #accesscontrols and logging/monitoring, segregation of environments, and secure-by-default configurations. 3. Deployment: - Establish #incidentresponse, escalation and remediation plans. - Release #AIsystems only after subjecting them to appropriate and effective security checks and evaluation. 4. Operations and Maintenance: - Monitor and log inputs (queries, prompts and requests) and outputs to ensure they are performing as intended. - Adopt a secure-by-design approach to updates and continuous learning. - Establish a vulnerability disclosure process for users to share potential #vulnerabilities to the system. 5. End of Life: - Ensure proper data and model disposal according to relevant industry standards or #regulations.

Whether you’re integrating a third-party AI model or deploying your own, adopt these practices to shrink your exposed surfaces to attackers and hackers: • Least-Privilege Agents – Restrict what your chatbot or autonomous agent can see and do. Sensitive actions should require a human click-through. • Clean Data In, Clean Model Out – Source training data from vetted repositories, hash-lock snapshots, and run red-team evaluations before every release. • Treat AI Code Like Stranger Code – Scan, review, and pin dependency hashes for anything an LLM suggests. New packages go in a sandbox first. • Throttle & Watermark – Rate-limit API calls, embed canary strings, and monitor for extraction patterns so rivals can’t clone your model overnight. • Choose Privacy-First Vendors – Look for differential privacy, “machine unlearning,” and clear audit trails—then mask sensitive data before you ever hit Send. Rapid-fire user checklist: verify vendor audits, separate test vs. prod, log every prompt/response, keep SDKs patched, and train your team to spot suspicious prompts. AI security is a shared-responsibility model, just like the cloud. Harden your pipeline, gate your permissions, and give every line of AI-generated output the same scrutiny you’d give a pull request. Your future self (and your CISO) will thank you. 🚀🔐

Yesterday, the National Security Agency Artificial Intelligence Security Center published the joint Cybersecurity Information Sheet Deploying AI Systems Securely in collaboration with the Cybersecurity and Infrastructure Security Agency, the Federal Bureau of Investigation (FBI), the Australian Signals Directorate’s Australian Cyber Security Centre, the Canadian Centre for Cyber Security, the New Zealand National Cyber Security Centre, and the United Kingdom’s National Cyber Security Centre. Deploying AI securely demands a strategy that tackles AI-specific and traditional IT vulnerabilities, especially in high-risk environments like on-premises or private clouds. Authored by international security experts, the guidelines stress the need for ongoing updates and tailored mitigation strategies to meet unique organizational needs. 🔒 Secure Deployment Environment: * Establish robust IT infrastructure. * Align governance with organizational standards. * Use threat models to enhance security. 🏗️ Robust Architecture: * Protect AI-IT interfaces. * Guard against data poisoning. * Implement Zero Trust architectures. 🔧 Hardened Configurations: * Apply sandboxing and secure settings. * Regularly update hardware and software. 🛡️ Network Protection: * Anticipate breaches; focus on detection and quick response. * Use advanced cybersecurity solutions. 🔍 AI System Protection: * Regularly validate and test AI models. * Encrypt and control access to AI data. 👮 Operation and Maintenance: * Enforce strict access controls. * Continuously educate users and monitor systems. 🔄 Updates and Testing: * Conduct security audits and penetration tests. * Regularly update systems to address new threats. 🚨 Emergency Preparedness: * Develop disaster recovery plans and immutable backups. 🔐 API Security: * Secure exposed APIs with strong authentication and encryption. This framework helps reduce risks and protect sensitive data, ensuring the success and security of AI systems in a dynamic digital ecosystem. #cybersecurity #CISO #leadership
