Payment Card Industry (PCI) Data Security Standards Practice Test

What is a requirement regarding intrusion detection systems according to PCI standards?

1. Intrusion detection techniques are required on all system components

2. Intrusion detection techniques are required to alert personnel of suspected compromises

3. Intrusion detection techniques are required to isolate systems from other systems

4. Intrusion detection techniques are required to identify all instances of cardholder data

The correct answer is: Intrusion detection techniques are required to alert personnel of suspected compromises

The requirement that intrusion detection techniques are necessary to alert personnel of suspected compromises is crucial for maintaining the security of cardholder data. This measure ensures that organizations are proactive in their approach to security, enabling them to respond swiftly to potential threats or breaches. By incorporating intrusion detection systems, businesses can monitor network activity and receive timely notifications when suspicious behavior is detected. This allows for immediate investigation and remediation, minimizing the impact of potential security incidents. The focus on alerting personnel is aligned with the broader goals of the PCI Data Security Standards, which emphasizes risk management and incident response. Timely alerts enhance an organization's ability to protect sensitive information and maintain compliance with PCI requirements, reinforcing the need for vigilant monitoring of network activities related to cardholder data.
