Answer:
The correct answer is letter (1): companies to ignore IDS alerts.
Explanation:
An Intrusion Detection System (IDS) is a software destined for the detection of unauthorized access in devices or a network. The systems administrator can manage the recognition of an intruder thanks to an alert that is activated when such a thing happens.
The problem comes when false IDS alarms are repeated constantly. At a certain point, the system administrator might ignore the IDS alert but it is recommended that every single alarm be analyzed for a real or false possible threat.
