What is a firewall in computing? What does a firewall do? We have some amazing firewall quiz questions and answers to make you aware of some interesting facts about a firewall. In computing, a firewall is a network security device that monitors and filters incoming and outgoing network traffic from attackers. Have you ever heard about VIRUS? What does it mean? The quiz below has many important security questions based on the firewall. Play it out and increase your knowledge about them.
- 1.
A ____ filtering firewall can react to an emergent event and update or create rules to deal with the event.
- A.
Dynamic
- B.
Static
- C.
Stateful
- D.
Stateless
Correct Answer
A. DynamicExplanation
A dynamic filtering firewall is able to react to an emergent event and update or create rules to deal with the event. This means that it can adapt and modify its filtering rules in real-time based on the current network conditions or threats. Unlike static filtering firewalls, which have predetermined rules that do not change, a dynamic filtering firewall provides greater flexibility and responsiveness in handling unexpected events or changes in the network environment. Additionally, stateful firewalls can maintain information about the state of network connections, allowing them to make more informed decisions when filtering traffic.Rate this question:

The ____ is an intermediate area between a trusted network and an untrusted network.
- A.
DMZ
- B.
Domain
- C.
Firewall
- D.
Perimeter
Correct Answer
A. DMZExplanation
A DMZ, or Demilitarized Zone, is an intermediate area between a trusted network and an untrusted network. It acts as a buffer zone that separates the internal network from the external network, providing an additional layer of security. The DMZ typically contains servers and services that need to be accessible from the internet, such as web servers or email servers. By placing these systems in the DMZ, it helps to protect the internal network from potential threats originating from the untrusted network while still allowing controlled access to specific services.Rate this question:

____ is the protocol for handling TCP traffic through a proxy server.
- A.
Https
- B.
Socks
- C.
FTP
- D.
Telnet
Correct Answer
B. SocksExplanation
The correct answer is Socks. Socks is the protocol used for handling TCP traffic through a proxy server. It allows clients to connect to a proxy server and then make requests through the proxy to the destination server. This enables the client to hide its identity and location, as well as bypass any restrictions or firewalls that may be in place. Socks is commonly used for activities such as anonymous browsing, accessing geo-restricted content, and enhancing security and privacy.Rate this question:

In ____ mode, the data within an IP packet is encrypted, but the header information is not.
- A.
Tunnel
- B.
Transport
- C.
Public
- D.
Symmetric
Correct Answer
A. TunnelExplanation
In tunnel mode, the data within an IP packet is encrypted, but the header information is not. This means that the payload of the packet is encrypted, providing secure communication between two endpoints, while the header information remains visible. Tunnel mode is often used when creating a virtual private network (VPN) to securely connect two networks over an untrusted network, such as the internet.Rate this question:

What is a network layer firewall also called?
- A.
Stateful Filters
- B.
Packet Filters
- C.
Area Filters
- D.
SecuredN
Correct Answer
B. Packet FiltersExplanation
A network layer firewall is also called a "Packet Filter." This type of firewall operates at the network layer of the OSI model and examines each packet's header information to determine whether to allow or block it based on predefined rules. Packet filtering firewalls are commonly used to filter traffic based on IP addresses, ports, and protocols, providing a basic level of security for a network by controlling the flow of packets.Rate this question:

What is an IPS?
- A.
Intrusion Prevention System
- B.
Intrinsic Prevention Security
- C.
Intrusion Prevention Security
- D.
Intrusive Prevention Security
Correct Answer
A. Intrusion Prevention SystemExplanation
An IPS stands for Intrusion Prevention System, which is a security technology designed to detect and prevent unauthorized access or attacks on a network or computer system. It actively monitors network traffic, analyzes it for potential threats, and takes immediate action to block or mitigate any suspicious or malicious activities. It helps to protect the system from various types of attacks, such as malware, viruses, unauthorized access attempts, and denial of service attacks.Rate this question:

What were the second generation firewalls called?
- A.
State Secured Filters
- B.
Circuit Level Getaways
- C.
Unit Secured Filters
- D.
Generation of Filters III
Correct Answer
A. State Secured FiltersExplanation
The second generation firewalls were called State Secured Filters.Rate this question:

The Next-Generation Firewalls (NGFWs) belong to which generation?
- A.
First
- B.
Second
- C.
Third
- D.
Fourth
Correct Answer
C. ThirdExplanation
The Next-Generation Firewalls (NGFWs) belong to the third generation of firewalls. NGFWs are an advanced form of firewalls that combine traditional firewall capabilities with additional features such as intrusion prevention, application awareness, and deep packet inspection. These features allow NGFWs to provide more advanced threat detection and prevention capabilities compared to previous generations of firewalls.Rate this question:

Application-level gateway is also known as a proxy firewall.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
An application-level gateway is a type of firewall that operates at the application layer of the network protocol stack. It acts as an intermediary between the client and the server, examining and filtering network traffic based on the application-specific rules. This type of firewall can provide additional security measures by inspecting the content of the application data. Therefore, it is correct to say that an application-level gateway is also known as a proxy firewall.Rate this question:

What port does secure HTTP use?
- A.
TCP port 550
- B.
TCP port 443
- C.
TCP port 399
- D.
TCP port 250
Correct Answer
B. TCP port 443Explanation
Secure HTTP, also known as HTTPS, uses TCP port 443. This port is specifically designated for secure communication over the internet. When a user accesses a website with HTTPS, the data exchanged between the user's browser and the website is encrypted to ensure confidentiality and integrity. TCP port 443 is commonly used for secure web browsing, online banking, e-commerce transactions, and other secure online activities.Rate this question:
