When you make a request for a webpage, your browser will send several headers of varying types. The application is protected by a certain group of headers that are either in the request or the response. These headers are applied by the website administrators themselves. The majority of software developers look for headers that are straightforward to use and address a wide variety of potential vulnerabilities. Each header serves a unique purpose, and the manner in which it is implemented also differs from case to case. Despite this, the manner in which the header is used is determined by the type of vulnerability the application administrator wishes to address before making his choice regarding which header to use.

Applications will be shielded from vulnerabilities thanks to the correct configuration of these headers, and an attacker will be unable to carry out any malicious POCs that steal data because of this protection. The vast majority of headers are implemented on the server side, which makes it significantly more challenging for an adversary to get around them.

Security header that are needed for application

In this blog post, we will be covering the most crucial five headers that need to be included in order to strengthen an application’s security and prevent it from vulnerability. Although every application contains a few headers, these headers will be the focus of our discussion. Permit me to go into further depth about them:

X-Frame-Options header


We make use of this response header to prevent pages from being framed by other pages and to prevent the browser from rendering a web page within an object, an iframe, or a frame element. Both of these things can occur when a page is framed.

This header is quite beneficial in decreasing the possibility of clickjacking attacks because the material cannot be incorporated into the other website. When it comes to the X-Frame-options header, you have the choice between “deny” and “SameOrigin.”
