Network Penetration Testing

Testing networks for vulnerabilities

Network penetration testing (Net PT) is the process of identifying, analyzing, and exploiting vulnerabilities in network systems to find ways to compromise system security.

5 minutes 5 Questions

Network Penetration Testing is a systematic assessment of network security by simulating attacks to identify vulnerabilities in network infrastructure. As a Penetration Tester, I approach this task methodically through several phases. First, I conduct reconnaissance to gather network information, …

Penetration Tester - Network Penetration Testing Example Questions

Test your knowledge of Network Penetration Testing

Question 1

What is the main purpose of a port scan?

To identify the specific user accounts available on a network To identify the domain name of a network To identify the type of operating system that is running on a network or device To identify open and vulnerable ports on a network or device To identify the type of encryption used on a network To identify the location of a device on a network

Correct Answer: To identify open and vulnerable ports on a network or device

A port scan is a critical step in network penetration testing that looks for open and vulnerable ports on a target network or device. This can help attackers identify potential entry points and weaknesses that can be exploited to gain access to systems or data.

Question 2

Which attack vector involves exploiting a vulnerability in a web application's code to gain unauthorized access to sensitive data or execute malicious commands?

A phishing attack targeting employees through email. A man-in-the-middle (MITM) attack to intercept network traffic. An ARP spoofing attack to intercept traffic on a local network. A SQL injection attack. A buffer overflow attack to crash a web server. A distributed denial-of-service (DDoS) attack.

Correct Answer: A SQL injection attack.

SQL injection attacks are one of the most common and dangerous methods of exploiting a web application's vulnerabilities. Attackers can use these attacks to steal sensitive information or execute malicious commands, leading to a range of consequences, including data breaches, identity theft, and system damage.

Question 3

What is the purpose of port scanning in network penetration testing?

To shut down all of the ports and prevent future attacks To obscure the network's IP address and location To overload the network with traffic and cause a denial-of-service attack To encrypt all of the open ports to prevent attacks To gain remote access to network devices To determine which ports are open and potentially vulnerable to attacks

Correct Answer: To determine which ports are open and potentially vulnerable to attacks

Port scanning is an essential step in network penetration testing. It allows the tester to identify which ports are open and potentially vulnerable to attacks, such as unauthorized access or denial of service.
