Internal Audit: Minimize Risks with Strong Practices
An Internal Audit of Operational Technology (OT) focuses on the hardware and software systems that control and monitor physical processes, such as manufacturing, energy production, transportation, and utilities.
Uncover the Key Aspects of an OT Audit:
- Security Assessment: Evaluate the cybersecurity measures in place to protect industrial control systems and critical infrastructure components. Identify vulnerabilities, assess access controls, and ensure effective incident response procedures.
- Compliance Check: Ensure compliance with relevant regulations and standards specific to operational technology, including NIST's Cybersecurity Framework, ISA/IEC 62443, and sector-specific standards like NERC CIP for the energy sector.
- Asset Inventory: Obtain a comprehensive inventory of all OT assets (hardware and software) to understand their status and interconnections.
- Network Architecture: Examine the network structure of the OT environment, pinpoint potential vulnerabilities, and assess device and system connections.
- Risk Assessment: Evaluate the risks associated with OT systems, identifying potential threats and their impact on critical operations.
- Physical Security: Assess physical security measures, including access controls and environmental controls.
- Documentation Review: Ensure systems are well-documented and personnel have access to the necessary information by reviewing system design, configuration, and procedural documentation.
- Testing and Simulation: Conduct penetration testing, vulnerability scanning, and tabletop exercises to identify security weaknesses and test incident response capabilities.
- Recommendations and Remediation: Receive a detailed report containing findings, recommendations, and a roadmap for addressing any identified issues or vulnerabilities.
Don't leave your operational technology systems vulnerable to attacks. Conducting an Internal Audit is crucial for identifying weaknesses and vulnerabilities, such as misconfigurations and software flaws, that could be exploited by hackers. Evaluate your security controls and measures to ensure they're effective. An Internal Audit helps you assess the strength of your access controls, network segmentation, and incident response procedures. Stay compliant with regulations and standards.
An Internal Audit will ensure you're following guidelines such as NERC CIP and ISA 62443, giving you peace of mind. Bolster your resilience against cyber-attacks and threats.
By identifying areas for improvement and implementing stronger security controls, an Internal Audit helps you enhance your defenses. Minimize disruptions and downtime risks. With an Internal Audit, you can identify potential risks and implement measures to mitigate them, reducing the chances of costly disruptions. Build trust and confidence. Especially for organizations providing critical services like power and transportation, an Internal Audit demonstrates your commitment to security and reliability, earning the trust of your stakeholders.
Discover the Audit's Scope and Objectives
The first step is to clearly define what areas will be covered by the Internal Audit and what goals it aims to achieve. This involves identifying the critical assets and systems that will be audited, determining the audit methodology, and establishing the expected outcomes.
Thoroughly Catalogue the Assets: The next step is to compile a comprehensive inventory of all operational technology (OT) assets and systems in use. This includes SCADA systems, DCS, PLCs, and similar technologies. The inventory should encompass hardware, software, and firmware components.
Uncover Vulnerabilities and Weaknesses: The following step involves identifying any potential vulnerabilities and weaknesses present in the OT systems. This may involve conducting vulnerability scans and penetration tests to pinpoint security flaws and misconfigurations that could be exploited by malicious actors.
Identify Potential Threats: The next task is to analyze and identify potential threats that could impact the OT systems. This could include reviewing threat intelligence reports, performing threat modeling exercises, and analyzing historical attack data.
Analyze and Mitigate Risk: Now, it's time to assess the risks associated with the vulnerabilities and threats identified. This includes evaluating the likelihood and impact of an attack on the OT systems, as well as assessing the effectiveness of existing risk mitigation strategies.
Evaluate Existing Security Controls: The next step is to assess the effectiveness of the security controls and measures currently in place to safeguard the OT systems. This involves reviewing access controls, network segmentation, and incident response procedures.
Ensure Compliance with Regulations and Standards: The final step is to ensure that the audited systems comply with relevant regulations, standards, and guidelines, such as NERC CIP and ISA 62443.
