Bug hunting is the process of finding bugs in software or hardware. As people in the security domain, we use this term to describe the process of finding security-critical software bugs. Security-critical bugs also called software security vulnerabilities. These vulnerabilities might allow an attacker to remotely compromise systems, escalate local privileges, cross privilege boundaries, or otherwise wreak havoc on a system.
HTTP Security headers are security mechanisms that you can use to protect your web application. Those headers provide extra protection layers. This is a fundamental part of web application security. You can easily configure your web application and implement required security header information for your application. After the implementation, these security headers protect your application against the type of attacks such as XSS, code injection, clickjacking, etc.
