   A security team has an attack surface rule that blocks suspicious PowerShell execution. The rule is generating a high number of false positives because legitimate IT automation scripts also use PowerShell. The team needs to reduce false positives without missing real attacks. The rule currently has a single trigger for 'powershell.exe' with no filters. What is the most effective tuning approach?

   • AChange the rule action from 'block' to 'alert' to reduce business disruption.
   • BDelete the rule and rely on other detection content to identify PowerShell attacks.
   • CIncrease the rule's severity so analysts focus on the most critical alerts.
   • DAdd filters to exclude known-good automation scripts, such as specific script paths or signed script publishers.
