Nikto
Nikto is an open-source web server scanner that performs comprehensive tests against web servers for multiple items, including potentially dangerous files, outdated server software, and configuration issues. It is designed to identify vulnerabilities and security misconfigurations in web applications and servers, providing detailed reports to help security professionals assess risks. The tool is written in Perl and is widely used for penetration testing and vulnerability assessment in cybersecurity.
Developers should learn and use Nikto when conducting security assessments of web applications or servers to identify common vulnerabilities such as misconfigurations, outdated software, and insecure files. It is particularly useful in penetration testing, compliance audits, and proactive security monitoring to ensure web infrastructure is hardened against attacks. For example, it can help detect issues like exposed sensitive directories, default files, or known vulnerabilities in web server software like Apache or Nginx.
