Getting Started with Nikto
Now for the dirty part, let's dive straight into it:
Before we dive into the details, let's kick things off with the basics:
Installation: Nikto can be installed on most Linux distributions. If it's not already installed, a straightforward installation command will do the trick. Ensure you have it up and running before proceeding.
Basic Usage: Nikto operates via the command line. To initiate a scan, you'll use a command structure like this:

Replace http://example.com with the target website's URL. This basic command will perform a default scan, highlighting any discovered vulnerabilities.
Customizing Your Nikto Scans
Here's where the magic begins. Nikto's true power lies in its flexibility and customization options. Let's explore some of the essential flags and usage examples:
Port Specification: Nikto allows you to specify the port to scan. For example, to scan a specific port (e.g., 8080), use:
nikto -h http://example.com:8080
Output Format: Nikto provides various output formats, including plain text, HTML, XML, and CSV. To generate an HTML report, use the -o flag:
nikto -h http://example.com -o scan_report.html
Custom Plugins: Nikto supports custom plugins, allowing you to extend its functionality. Use the -Plugins flag to specify custom plugins:
nikto -h http://example.com -Plugins=custom_plugin.nasl
Tuning Profiles: Adjust the scan intensity with tuning profiles. For example, use the -Tuning flag to specify a tuning profile (e.g., 3 for a comprehensive scan):
nikto -h http://example.com -Tuning 3
Advanced Nikto Tactics
Take your Nikto skills to the next level with these advanced tactics:
Authentication: Nikto supports basic authentication. To scan protected areas of a website, use the -id flag with your credentials:
nikto -h http://example.com -id "username:password"
Proxy Support: If you need to scan websites behind a firewall, Nikto can operate through a proxy server. Utilize the -useproxy flag:
nikto -h http://example.com -useproxy http://proxy.example.com:8080
Integration and Automation: Integrate Nikto into your security workflows and scripts for automated scans and reporting.
I hope I was able to convey the utility of Nikto for your toolbag. It can help you uncover vulnerabilities and secure your online domains.
