Web security refers to the measures and practices designed to protect websites and web applications from cyber threats and vulnerabilities. As the internet continues to grow, so does the risk of attacks such as cross-site scripting (XSS), SQL injection, and data breaches. Effective web security involves implementing protocols like HTTPS, utilizing secure coding practices, and regularly updating software to mitigate risks. Organizations must also conduct security audits and stay informed about emerging threats to safeguard sensitive user data and maintain trust. Understanding web security is essential for developers, businesses, and users alike to navigate the digital landscape safely.
