Option B is the most precise and effective method. By implementing a conditional exclusion, you can specify exact circumstances under which the legitimate process should NOT trigger an alert, while still allowing the rule to catch instances where the same process might be used maliciously (e.g., if its parent process or command line arguments differ). This maintains the rule's fidelity for true threats while eliminating specific false positives. Options A, C, D, and E are either ineffective, harmful to detection, or merely reactive.
