Fortinet Interview Questions

Top 30 Fortinet Interview Questions and Answers in 2021

Welcome to the Fortinet interview questions blog. Before jumping right into the blog, let’s analyze some basic security challenges. The usage of  IoT(Internet of Things) is rapidly growing over the years, but the challenges are also growing simultaneously. One of the recent studies says that 70% of most commonly used IoT devices face security vulnerabilities.

Let us take automotive vehicles as an example: IoT connected vehicles provide customers everything automatically from routing, smart traffic management to intelligent safety and system maintenance. Everything is automatic, and for this, customers may have to connect different devices with the vehicle. This is where the problem ignites when personal devices are connected to the vehicle. The attacker/hacker may hack the data flowing between the IoT device(in this case, it is the vehicle) and the cloud applications.

Fortinet security fabric introduces an architectural approach to security; this fabric mainly provides three core digital innovations: broad visibility, integrated solutions, and self-healing networks. Fortinet has secured a leadership position in the cybersecurity field and there are a good number of job opportunities available for skilled candidates. Following are the frequently asked Fortinet interview questions. All the very best.

Frequently Asked Fortinet Interview Questions and Answers

1. Tell me who started Fortinet and when?

3. Is Fortinet FortiGate a good firewall?

Whenever someone wants to buy a firewall, he checks whether the firewall provides good security or not. He will also check if the firewall is at a reasonable price or not, as the Fortinet FortiGate firewall offers robust security and comes at an affordable price(starting from 37,987).

4. Tell something about a traditional firewall?

A traditional firewall is a network security device that statefully examines the network traffic entering and exiting points within the network based on state, port, and protocol. Traditional firewalls can only track traffic on 2-4 layers; this makes traditional firewalls less effective to provide the protection needed to handle all the advanced cyber threats happening in this digital era.

Traditional Firewall

Next-generation Firewall

It works only from layer 2 to layer 4.

It works on layer 2 to layer 7.

Application-level awareness is not supported in the traditional firewall.

Application-level awareness is supported in the traditional firewall.

Traditional firewalls do not support reputation and identity services.

Fortinet Security Fabric addresses the below security challenges:

  1. Expanding attack surface
  2. Advanced threat landscape
  3. Grater ecosystem complexity
  4. Increasing regularity demands

9. Why do we have to use Fortinet UTM?

Many firewalls and router-based hardware are having lack to provide the ability to see the applications that are crossing the network and making decisions based on this data. But Fortinet UTM provides the availability to see the applications that are traversing the network. Due to this information, the administrator can make decisions on whether to deny or allow the traffic.

10. What is integrated threat management?

Integrated threat management is a security approach that consolidates various security components within one application or platform for an IT enterprise architecture.

ITM emerged as a response to increasingly complicated and persistent malicious attacks by hackers and others intent upon damaging systems.
