It’s crucial for webmasters and system administrators to ensure that their servers are secure. One of the most effective ways to measure a server’s security is by performing vulnerability tests.
Metasploit, a powerful penetration testing tool, can be used for this purpose.
This tutorial will guide you through the process of setting up Metasploit on a Linux machine to perform a security vulnerability test. By the end of this guide, you’ll have a better understanding of how to gauge the security of your server using Metasploit.
Prerequisites
- A Linux machine (preferably Ubuntu or Debian).
- Root or sudo access to the machine.
- Basic understanding of Linux command line.
- A stable internet connection.
Let’s get started.
Step 1: Update and Upgrade Your System
Before installing any new software, it’s a good practice to update and upgrade your system. This ensures that you have the latest security patches and software versions.
sudo apt update sudo apt upgrade -y
Step 2: Install Metasploit Framework
Metasploit Framework is available in the default repositories of many Linux distributions. However, to get the latest version, it’s recommended to use the official Rapid7 repositories.
curl -O https://apt.metasploit.com/metasploit-framework.gpg.key sudo apt-key add metasploit-framework.gpg.key echo "deb https://apt.metasploit.com/ $(lsb_release -cs) main" | sudo tee -a /etc/apt/sources.list.d/metasploit-framework.list sudo apt update sudo apt install metasploit-framework
Step 3: Initialize the Metasploit Database
Metasploit uses a PostgreSQL database to store its data. Initialize it with the following commands:
sudo service postgresql start sudo msfdb init
Step 4: Launch Metasploit
Now that Metasploit is installed and the database is initialized, you can start the Metasploit console:
msfconsole
Example:
=[ metasploit v6.0.0-dev ]
+ -- --=[ 2049 exploits - 1122 auxiliary - 352 post ]
+ -- --=[ 592 payloads - 45 encoders - 10 nops ]
+ -- --=[ 7 evasion ]

Step 5: Conduct a Vulnerability Test
With Metasploit running, you can now perform a vulnerability test. For the purpose of this tutorial, we’ll use a basic scan to identify open ports on a target machine.
use auxiliary/scanner/portscan/tcp set RHOSTS target_ip_address run
Replace target_ip_address with the IP address of the server you want to test.
For example:
msf6 > use auxiliary/scanner/portscan/tcp msf6 auxiliary(scanner/portscan/tcp) > set RHOSTS 65.8.134.11 RHOSTS => 65.8.134.11 msf6 auxiliary(scanner/portscan/tcp) > run [*] Scanning IP: 65.8.134.11... [+] 65.8.134.11: 22/tcp - SSH [+] 65.8.134.11: 80/tcp - HTTP [-] 65.8.134.11: 443/tcp - Closed [*] Scanned 1 of 1 hosts (100% complete) [*] Auxiliary module execution completed msf6 auxiliary(scanner/portscan/tcp) >
Step 6: Analyze the Results
After the scan completes, review the results to identify open ports and potential vulnerabilities. Remember, this is just a basic scan. Metasploit offers a plethora of modules and exploits to test various vulnerabilities.
Commands Mentioned
- sudo apt update – Updates the package list for upgrades and new package installations.
- sudo apt upgrade – Installs the newest versions of all packages currently installed on the system.
- msfconsole – Launches the Metasploit console.
- use auxiliary/scanner/portscan/tcp – Selects the TCP port scanner module in Metasploit.
- set RHOSTS – Sets the target IP address for the scan.
- run – Executes the selected module.
FAQ
-
What is Metasploit used for?
Metasploit is a penetration testing tool used to discover, exploit, and validate vulnerabilities within systems. It provides a comprehensive environment for cybersecurity professionals to assess security risks, conduct vulnerability tests, and simulate cyber-attacks in a controlled environment.
-
Is it legal to use Metasploit?
Yes, using Metasploit is legal for legitimate, ethical purposes such as vulnerability testing and research. However, using it for malicious intent or without proper authorization on a system is illegal and can lead to severe consequences.
-
How does Metasploit work?
Metasploit operates by providing a range of tools that can be used to identify vulnerabilities, develop and execute exploits, and establish a post-exploitation presence on a target system. It contains a vast database of exploits and payloads, allowing users to simulate real-world cyber-attacks.
-
Why is vulnerability testing important?
Vulnerability testing is crucial as it helps organizations identify security weaknesses in their systems before malicious actors do. By proactively detecting and addressing vulnerabilities, organizations can prevent potential cyber-attacks, data breaches, and ensure the integrity and confidentiality of their data.
-
Can Metasploit be used on all operating systems?
Metasploit is primarily designed for Unix-based systems, including Linux and macOS. However, there is a version available for Windows as well. While the core functionalities remain consistent across platforms, there might be some differences in terms of specific modules or tools available for each operating system. It’s always recommended to check the compatibility of specific modules with your operating system before proceeding with any tests.
Conclusion
Ensuring the security of your server is paramount in today’s digital age. Vulnerabilities can lead to data breaches, unauthorized access, and other malicious activities that can harm both organizations and their clients. Tools like Metasploit provide a comprehensive platform for webmasters, system administrators, and cybersecurity professionals to test and bolster their server’s security.
By following this tutorial, you’ve taken a significant step towards understanding and improving the security posture of your server. Always remember to conduct vulnerability tests ethically and responsibly.
