156-315.81.20 Threat Prevention and SandBlast Practice Question
A security administrator needs to ensure that all encrypted traffic is inspected by the Threat Prevention blades. What is the mandatory requirement for this?
⚠ Common exam trap
Candidates often believe that enabling Threat Prevention alone is sufficient to inspect encrypted traffic, forgetting the prerequisite step of configuring HTTPS Inspection and distributing certificates.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the HTTPS Inspection policy and install the CA certificate on all client machines.
HTTPS Inspection is essential because many threats are delivered over encrypted channels to bypass inspection. By performing HTTPS Inspection, the gateway decrypts the traffic, inspects the payload using Threat Prevention blades, and re-encrypts it before sending it to the destination. This provides full visibility into the traffic, ensuring that malicious content hidden within encrypted payloads is effectively detected and blocked before reaching the internal network or the user's endpoint.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable SSL Inspection in the Threat Prevention policy.
Why it's wrong here
While SSL inspection is the general category, the specific feature is called 'HTTPS Inspection' in Check Point. Simply checking a box in the Threat Prevention policy is not the complete configuration; it requires the deployment of an HTTPS Inspection policy and the installation of a CA certificate on endpoints.
- ✓
Configure the HTTPS Inspection policy and install the CA certificate on all client machines.
Why this is correct
HTTPS Inspection requires the gateway to act as a proxy. To prevent browser certificate errors, the gateway's CA certificate must be trusted by all internal clients. This configuration enables the gateway to decrypt, inspect, and re-encrypt traffic, ensuring that Threat Prevention blades can process the decrypted data streams.
- ✗
Upgrade to the latest JHF (Jumbo Hotfix) on the Management Server only.
Why it's wrong here
Jumbo Hotfixes contain bug fixes and performance improvements but do not automatically enable HTTPS Inspection. This feature is a functional configuration that requires specific policy settings on the gateway and client-side trust, regardless of the software version or the hotfix level installed on the Management Server environment.
- ✗
Enable the 'Deep Packet Inspection' blade globally on all interfaces.
Why it's wrong here
There is no 'Deep Packet Inspection' blade in Check Point; this is a generic industry term. Threat Prevention blades perform deep inspection, but they require the traffic to be decrypted first via the HTTPS Inspection feature to operate on encrypted traffic flows effectively across the network infrastructure.
