4. Running Nikto Scans: A Step-by-Step Guide
Now that you have Nikto installed on your system, it’s time to put it to work and start scanning your website for potential security vulnerabilities. Nikto offers a range of scanning options, allowing you to tailor your approach based on your specific needs and the characteristics of your website.
Conducting Basic Domain Scans:
To perform a basic scan of a domain using Nikto, you can use the “-h” (host) flag followed by the domain name you want to scan. For example:
“`
nikto -h scanme.nmap.org
“`
This command tells Nikto to perform a scan on port 80 (the default HTTP port) for the domain “scanme.nmap.org”. Nikto will then generate a report summarizing its findings.
Scanning HTTPS-Enabled Websites:
If the website you’re scanning uses the secure HTTPS protocol, you’ll need to add the “-ssl” flag to instruct Nikto to scan the appropriate port (usually 443) where HTTPS traffic is typically handled. For example:
“`
nikto -h nmap.org -ssl
“`
This command tells Nikto to scan the domain “nmap.org” over HTTPS and specifically target port 443.
Scanning by IP Address:
If you need to scan a web server based on its IP address, you can use the same “-h” flag, but instead of a domain name, you’ll provide the IP address. For example:
“`
nikto -h 45.33.32.156
“`
This command instructs Nikto to scan the web server hosted at the IP address “45.33.32.156”.
Scanning Multiple Domains/IPs:
To scan multiple domains or IP addresses at once, you can create a text file with each target listed on a new line, and then use the “-input” flag to provide the file path. For instance, let’s say you have a file named “domains.txt” with the following contents:
“`
scanme.nmap.org
nmap.org
“`
You can then run the following command to scan both domains:
“`
nikto -input domains.txt
“`
Nikto will sequentially scan each target listed in the “domains.txt” file and provide you with a comprehensive report.
Remember, it’s crucial to obtain proper permission before scanning any systems or networks, as unauthorized access can be considered illegal. Always ensure you have the necessary authorization to conduct these security assessments.
5. Customizing and Exporting Nikto Scan Results
Nikto’s flexibility extends beyond just performing scans; it also allows you to customize the output of your findings and export them in various formats for future reference and collaboration.
Saving Scan Reports in Different Formats:
To save the results of a Nikto scan, you can use the “-o” (output) flag followed by the desired file name. For example:
“`
nikto -h scanme.nmap.org -o scan.txt
“`
This command tells Nikto to scan the domain “scanme.nmap.org” and save the results in a file named “scan.txt”.
Nikto supports a variety of output formats, including:
– CSV (Comma-Separated Values)
– HTML
– Nessus format (NBE)
– SQL
– Plain text (TXT)
– XML
You can specify the desired format using the “-format” flag. For example:
“`
nikto -h scanme.nmap.org -format csv -o scan.csv
“`
This command will generate a CSV file named “scan.csv” containing the details of the Nikto scan.
Integrating Nikto with Metasploit:
Metasploit is a powerful cybersecurity toolkit that is often used by security professionals for vulnerability testing and exploitation. Nikto makes it easy to integrate its findings directly with Metasploit, streamlining your workflow and ensuring a seamless transition from vulnerability identification to potential exploitation.
To export Nikto’s scan results to Metasploit, simply add the “-Format msf+” flag to your Nikto command:
“`
nikto -h [domain/IP] -Format msf+
“`
Replace “[domain/IP]” with the domain name or IP address you want to scan.
Once the scan is complete and the results are exported, you can import them into Metasploit and use them to further investigate or exploit any vulnerabilities that Nikto has identified. This integration allows you to leverage the strengths of both tools, enhancing your overall security testing capabilities.
By customizing Nikto’s output and seamlessly integrating it with other security tools like Metasploit, you can streamline your workflow, ensure comprehensive documentation, and effectively address the security concerns uncovered during your website assessments.
