1.) Network security aspect: Use a network based anti virus, anti malware, anti phishing, and so on. I'm talking about a software like a licenced Master anti virus. 2.) Data Backup: Have an AI/ML tool to constantly take backups, both on the organization's physical servers and cloud based platforms. 3.) OS: Always maintain two Data Centers, with two Operating Systems. Data Backup every moment is a must. The support staff goals are very well defined, and are meant to monitor the ERP related security operations. Create SOPs for every user across multiple verticals, and make them aware of risks that occur in ERP Systems' security. Access controls should be unique with two factor authentication.

Once you have your objectives, you need to choose the appropriate metrics to measure your ERP security controls. Metrics are quantitative or qualitative indicators that help you evaluate the status and progress of your security activities. You can use process metrics to measure the efficiency and effectiveness of security processes like incident response, patch management, access management, and audit management. Outcome metrics measure the impact and results of security processes, like the number and severity of incidents, the level of compliance, the cost of security, and customer satisfaction. Additionally, benchmark metrics compare your security performance against external or internal standards, such as industry best practices, peer groups, or historical data.
To measure your ERP security controls, you need to collect relevant and reliable data from various sources, such as ERP system logs that provide information on activities and events, ERP system reports that give insights into configuration and status, security tools that detect vulnerabilities and threats, and surveys and interviews that reveal stakeholders' perceptions and opinions. Collecting this data will help you understand the security of your ERP system and take necessary steps to protect it.
After collecting your data, you need to analyze it to identify patterns, trends, gaps, and opportunities. There are various methods and tools you can use for this, such as descriptive analysis which summarizes and presents your data in a clear way. Diagnostic analysis explores and explains the causes behind your data. Predictive analysis forecasts and estimates future outcomes based on your data. Lastly, prescriptive analysis recommends the optimal actions and decisions based on your data.
Finally, you need to communicate your results to your stakeholders and decision-makers in a timely and meaningful way. Reports, presentations, and alerts are all effective formats and channels for sharing your findings. Reports document and detail your findings and conclusions, while presentations highlight and emphasize key messages. Alerts notify and inform stakeholders about urgent and critical issues. It's important to remember that measuring ERP security controls is an ongoing process that requires regular monitoring, evaluation, and improvement. Following these tips will ensure that your ERP security controls are aligned with business objectives, meet compliance requirements, and protect data and assets.
