Why might a security analyst use scripting to create custom detection rules?

To automatically patch vulnerabilities

To detect threats that are not covered by built-in rules

What is the primary difference between an intrusion detection system (IDS) and an intrusion prevention system (IPS) in terms of response to detected threats?

Both IDS and IPS can block traffic, but only IDS can generate alerts.

An IPS only monitors, while an IDS can actively block traffic.

An IDS can block malicious traffic, while an IPS can only alert.

An IDS only monitors, while an IPS can actively block or drop malicious traffic.

What is the purpose of whitelisting in network monitoring?

To allow known-good traffic and reduce false positives

To replace the need for intrusion detection

To increase the number of alerts generated

To block all traffic from external networks

A company is adopting a cloud-based file sharing service for employee collaboration. The security team wants to monitor user activity, detect unauthorized sharing of sensitive data, and enforce data loss prevention (DLP) policies. Which solution should the team implement?

Implement an EDR solution on all employee devices.

Deploy a Cloud Access Security Broker (CASB) to monitor and enforce policies on the cloud service.

Use a network-based IDS to monitor traffic to the cloud service.

Configure the SIEM to collect logs from the cloud service.

Which technique can be used to detect IP address spoofing in network traffic?

Monitoring CPU usage on the firewall

Checking for packets with source IP addresses that do not match the expected subnet
