How to Run a Nikto Web Server Scan

Step 01
Enter your target

Enter a public IP address or hostname.

IP address or Hostname

Single — 192.168.1.1

List — 192.168.1.1, example.com

IP Range

CIDR — 192.168.1.0/24

Hyphenated — 192.168.1.1-50

Only scan systems you have permission to.
Step 02
Choose a User Agent

The User-Agent identifies the client type to the target server.

Change it to test how the server responds to different browsers, crawlers, or mobile clients.

Useful when scans are being blocked or filtered.

Step 03
Submit and Monitor Results

The scan runs automatically once submitted.

Allow up to 45 minutes for completion. Duration depends on server response times and number of checks performed.

Results are emailed to your registered address and available to view and download in the Members Dashboard.

Target Selection & Virtual Host

If your web server hosts multiple sites using virtual hosts. You should test each virtual host using Nikto to get greater vulnerability coverage. In fact it can be helpful to scan the IP address as well as the hostname of the server to ensure all paths are tested for any vulnerable web applications and scripts.

Understanding False Positives

Nikto checks hundreds of URLs, which can produce false positives when a server returns 200 OK for missing pages. These are easy to spot as a pattern and straightforward to verify manually.

Nikto is by no means a stealthy tool. It will make thousands of HTTP requests to the web server, creating a large number of entries in the web servers log files. This noise is an excellent way to test an in place Intrusion Detection System (IDS). Any web server log monitoring, host based intrusion detection (HIDS) or network based intrusion detection (NIDS) should detect a Nikto scan.

Nikto includes built-in evasion techniques -evasion for IDS bypass, these are available when running a local installation. The online scanner runs a default scan with no evasion applied.

The Nikto Web Vulnerability Scanner is a popular tool found in the toolkit of many penetration testers and security analysts. It will often discover interesting information about a web server or website that can be used for deeper exploitation or vulnerability assessment.

"Before you receive that notice or your site falls prey to a cyber attack, install Nikto on a remote computer and begin your assessments."
