Question 899 of 282
Block File Uploads to Cloud Storage via HTTPS: Required Security Profiles
An administrator wants to block users from uploading files to cloud storage services like Google Drive via HTTPS. Which security profile combination is required?
Quick Answer
The answer is an application control profile with deep inspection enabled. This combination is required because HTTPS traffic is encrypted, so deep inspection must first decrypt the session to allow the FortiGate to inspect the application layer. Once decrypted, the application control profile can identify and block cloud storage services like Google Drive or Dropbox based on their unique signatures. On the Fortinet NSE 4 exam, this scenario tests your understanding that blocking file uploads to cloud storage via HTTPS cannot rely on simple web filtering or antivirus alone—deep inspection is the critical enabler. A common trap is assuming a web filter profile can block HTTPS uploads, but without decryption, the firewall sees only encrypted tunnels. Remember the key chain: deep inspection decrypts, then application control blocks. Memory tip: “Decrypt first, then detect—no deep inspect, no effect.”
⚠ Common exam trap
Test-takers frequently assume a web filter or DNS filter can block specific actions within an encrypted session, but only application control with deep inspection can inspect HTTPS payloads to differentiate between uploading, downloading, or browsing.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Application control profile to block cloud storage applications, with deep inspection enabled
To block file uploads to cloud storage services like Google Drive over HTTPS, an application control profile is required because it can identify and control specific application actions (e.g., file uploads) within encrypted traffic. Deep inspection must be enabled to decrypt the HTTPS traffic, allowing the FortiGate to inspect the application-layer payload and enforce the upload blocking rule.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Application control profile to block cloud storage applications, with deep inspection enabled
Why this is correct
Application control can identify and block Google Drive traffic even over HTTPS, but only if deep inspection decrypts the traffic to read application signatures.
- ✗
IPS profile to block file uploads to cloud services
Why it's wrong here
IPS is for vulnerabilities, not for blocking specific application actions.
- ✗
DNS filter to block Google Drive domain
Why it's wrong here
DNS filter would block the entire domain, not just uploads.
- ✗
Web filter profile with URL filter to block Google Drive
Why it's wrong here
URL filter alone cannot block file uploads within the website; it either blocks the entire site or not.

Same concept, more angles

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An administrator wants to block users from uploading sensitive documents through webmail. Which security profile should be configured on the FortiGate to achieve this goal?
medium- ✓ A.Data Leak Prevention (DLP)
- B.Antivirus
- C.Application control
- D.Web filter
Why A: Data Leak Prevention (DLP) is the correct security profile because it is specifically designed to inspect content (e.g., file names, patterns, or keywords) in traffic such as webmail uploads and block sensitive data from leaving the network. DLP sensors can be configured with rules to match patterns like credit card numbers, social security numbers, or custom keywords, and then take action such as blocking or logging the session.
