About Nikto

Renowned open-source Nikto is a vulnerability assessment and web server scanner that may be used to find possible security flaws in web servers and apps. Nikto, a 2001 release that was created in Perl, automates the scanning process by looking for malicious files, unpatched vulnerabilities, and out-of-date software that can jeopardize server security. Web developers, security experts, and penetration testers utilize it extensively for audits and security assessments.

Best Features

1. Vulnerability Scanning

Nikto does a thorough scan of web servers, looking for misconfigurations, out-of-date software, and missing patches. This comprises 1200 out-of-date server versions, 6400 potentially hazardous files and scripts, and about 300 version-specific issues.

2. Web Application Security Testing:

The program evaluates the security of web applications by looking for widespread flaws, including directory traversal, SQL injection, and cross-site scripting (XSS).

3. Banner Grabbing:

Nikto helps with understanding the technology stack and discovering known vulnerabilities associated with particular versions by retrieving banners from web servers.

4. Identification of Outdated Software:

In order to minimize potential vulnerabilities, it looks for out-of-date plugins, extensions, and server software.

5. Default File and Directory Detection:

Nikto finds typical default files and directories—like configuration files, login pages, and backup files—that are inadvertently left visible on web servers.

6. SSL/TLS Vulnerability Scanning:

This tool verifies the implementation of a secure connection by looking for SSL/TLS vulnerabilities and misconfigurations.

7. Identification of Insecure Permissions:

Nikto looks for folders and files that have insecure permissions, which could be a weakness that hackers exploit to gain unauthorized access.

8. CGI Vulnerability Assessment:

Nikto looks for known CGI vulnerabilities and misconfigurations, which is very helpful for finding vulnerabilities in CGI scripts and programs that are often used on web servers.

9. Server Misconfigurations:

The program searches for frequently occurring server misconfigurations that could lead to security flaws or the exposure of private data.
