Automated information security controls are controls that are implemented or executed by software or hardware, without human intervention, to protect the confidentiality, integrity, and availability of information and systems1. Examples of automated information security controls include firewalls, antivirus software, encryption, authentication, and logging2. The effectiveness of automated information security controls refers to how well they achieve their intended objectives and outcomes, such as preventing, detecting, or responding to security threats or incidents3. The best way to measure the effectiveness of automatedinformation security controls prior to going live is to test them in a non-production environment, which is an environment thatsimulates the production environment, but does not contain real or sensitive data orsystems4. Testing in a non-production environment allows the organization to verify the proper and consistent configuration, functionality, and performance of the automated information security controls, without affecting the normal operations or risking the exposure of the data or systems5. Testing in a non-production environment also enables the organization to identify andresolve any issues or gaps in the automated information security controls, and to evaluate their compatibility and interoperability with other systems or controls6. Performing a security control review, reviewing the security audit report, and conducting a risk assessment are not the best ways to measure the effectiveness of automated information security controls prior to going live, as they do not provide direct and timely information on the configuration, functionality, and performance of the automated information security controls. Performing a security control review is a process that involves checking and verifying that the organization’s security controls are up to date, relevant, and effective7. A security control review can help to identify and address any issues or gaps in the security controls, but it does not show the actual behavior and results of the automated information security controls in a realistic environment. Reviewing the security audit report is a process that involves reading and analyzing the findings and recommendations of an independent examination and evaluation of the organization’s security controls8. A security audit report can help to provide assurance and advice on the adequacy and effectiveness of the security controls, but it does not show the current and dynamic status and performance of the automated information security controls in a changing environment. Conducting a risk assessment is a process that involves identifying, analyzing, and evaluating the risks and their potential impacts on the organization’s objectives and performance. A risk assessment can help to anticipate and prepare for the risks that may affect the organization’s security, but it does not show the actual impact and outcome of the automated information security controls in a specific scenario. References = 1: Automation Support for Security Control Assessments - NIST2: Automated Security Control Assessment: When Self-Awareness Matters3: Technology Control Automation: Improving Efficiency, Reducing … - ISACA4: [What is a Non-Production Environment? | Definition and FAQs] 5: [Why You Need a Non-Production Environment - Plutora] 6: [Testing Automated Security Controls - SANS Institute] 7: A brief guide to assessing risks and controls | ACCA Global8: IT Risk Resources | ISACA : [Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.1: Risk Identification, pp. 57-59.]
