For security requirements when using a SaaS back-office service, which solution best meets the needs?

• A. Firewall
• B. Cloud Access Security Broker
• C. Proxy gateway
• D. Intrusion prevention and detection system

Answer: (D)

The key idea here is real-time, inline protection of traffic to the SaaS back-office service. An intrusion prevention system sits in line with your network path and actively inspects traffic for known and unknown threats, blocking malicious activity as it’s detected. This directly helps prevent intrusions, malware ingress, and data exfiltration through the SaaS channel, which is crucial when you’re relying on a third-party service for back-office operations. It provides automated, immediate defense at the network level, without waiting for the provider to patch or configure defenses on their side. Firewall controls are important for deciding what can reach the network, but they don’t inherently detect and stop complex or evolving threats in real time. A Cloud Access Security Broker focuses on visibility, data security, and governance for cloud services, which is valuable but not primarily about blocking intrusions at the network edge. A proxy gateway mediates traffic and can filter content, but it doesn’t offer the same inline, signature-based and anomaly-based threat prevention that an IPS provides. So, for meeting security requirements with SaaS back-office usage, an intrusion prevention system delivers the direct threat-detection and -prevention capability that the scenario calls for.
