The first thing that should be done before allowing users to connect personal devices to the corporate network is to implement an acceptable use policy. An acceptable use policy is a document that defines the rules and guidelines for using personal devices on the corporate network, such as security requirements, access rights, responsibilities, and consequences. An acceptable use policy can help to protect the organization from potential risks such as data leakage, malware infection, or legal liability. The other options are not as important as implementing an acceptable use policy, as they do not establish the boundaries and expectations for using personal devices on the corporate network. References: CISA Review Manual, 27th Edition, page 318

The best way to prevent accepting bad data from a third-party service provider is to implement business rules to reject invalid data. Business rules are logical statements that define the data quality requirements and standards for the organization. By implementing business rules, the organization can ensure that only data that meets the predefined criteria is accepted into the enterprise data warehouse. Obtaining error codes indicating failed data feeds, purchasing data cleansing tools from a reputable vendor, and appointing data quality champions across the organization are useful measures to improve data quality, but they do not prevent accepting bad data in the first place. References: ISACA Journal Article: Data Quality Management

 Fine tuning the intrusion detection system (IDS) is the best recommendation to reduce the number of false positive alerts that overwhelm the log management system, because it can help adjust the sensitivity and accuracy of the IDS rules and signatures to match the network environment and traffic patterns. Establishing criteria for reviewing alerts, recruiting more monitoring personnel, and reducing the firewall rules are not effective solutions to address the root cause of the false positive alerts, but rather ways to cope with the consequences. References: CISA Review Manual (Digital Version), Chapter 5, Section 5.4.3
