SandBlast Appliances can be deployed in which of the following modes?

The correct answer indicates that SandBlast Appliances can operate in both Inline/Prevent and Detect modes, which showcases the versatility and functionality of these appliances in network security.

In the Inline/Prevent mode, the SandBlast Appliance sits directly in the data path of network traffic, allowing it to actively inspect, block, or allow traffic in real-time. This proactive approach ensures that threats are mitigated before reaching their intended targets, significantly enhancing an organization’s security posture.

In the Detect mode, the appliance monitors traffic without directly interfering with it, allowing for the identification of malicious activity while logging the observations for later analysis. This mode can be crucial for environments where uninterrupted data flow is necessary, and it allows security teams to gather intelligence and understand threat patterns without impacting user experience.

The other options reflect more limited or incorrect functions. For example, using a SPAN port would only allow for monitoring traffic but not provide active protection, which is a critical functionality of SandBlast Appliances. The term "Detect Only" suggests a singular capability, neglecting the proactive prevention aspect inherent in Inline operation. Moreover, designating the appliance as a Mail Transfer Agent is too restrictive and does not encompass its broader application across different network traffic types.
