How do access controls enhance cybersecurity in IACS?

• A. They restrict unauthorized access to systems and data
• B. They increase system processing speed
• C. They create backups for system recovery
• D. They enhance user experience and accessibility

Answer: (A)

Access controls play a crucial role in enhancing cybersecurity within Industrial Automation and Control Systems (IACS) by ensuring that only authorized individuals have access to sensitive systems and data. This restriction is essential to protect against unauthorized access, which could lead to malicious activities such as data breaches, system manipulation, or other forms of cyber-attacks. By implementing effective access controls, organizations can reduce the risk of insider threats and limit the potential exposure of critical information. This involves establishing strict authentication and authorization mechanisms that verify the identity of users before granting them access to systems. Consequently, access controls form a foundational element of a robust cybersecurity framework, enabling the protection of both the integrity and confidentiality of operational data. The other options, while they highlight various functions and benefits of technology, do not align with the primary purpose of access controls. Increasing processing speed and creating backups are important considerations in system performance and resilience but are not directly related to access security. Enhancing user experience or accessibility, though important for usability, does not inherently contribute to improving the security posture of IACS. Thus, the primary function of access controls remains focused on restricting unauthorized access, securing systems, and protecting sensitive data.
