Exploring the Power of the Nikto Tool in Web Security

Introduction

Websites have become indispensable tools for businesses and organisations worldwide today. Whether you own a local restaurant or a global brand, having an online presence is crucial for establishing and maintaining your brand identity. However, amidst the convenience and accessibility offered by websites, there lies a significant threat: security vulnerabilities.
Indeed, websites serve as prime targets for attackers looking to exploit loopholes and gain unauthorised access to sensitive data. What's more alarming is that many websites lack the robust security measures needed to fend off such threats.
In light of this, it's challenging for organisations, especially those without extensive technical expertise, to prioritise understanding website and web application security.
