Implementing Secure Cookie Configuration in Spring Security

Cookies are small pieces of data that are sent by a server to a client and stored on the client's machine. They play a crucial role in maintaining session information and can be used for various purposes in web applications. However, if not configured securely, cookies can become vulnerable to attacks such as session hijacking or cross-site scripting.

In the context of a Spring Security course, it is essential to understand how to implement secure cookie configuration to protect sensitive user data and maintain the integrity of your application. This article will guide you through the process of configuring secure cookies using Spring Security.

Step 1: Add Spring Security Dependency

First, make sure you have the necessary Spring Security dependency added to your project. You can include the following dependency in your pom.xml if you are using Maven:


Next, you need to configure the properties for secure cookies in your Spring Security configuration. This can be done by creating a class that extends WebSecurityConfigurerAdapter and overriding the configure(HttpSecurity http) method. Here's an example:

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    protected void configure(HttpSecurity http) throws Exception {
                // Configure your URL patterns and access rules here
                // Configure your login page and success URL here
                .loginPage("/login").defaultSuccessUrl("/dashboard", true)
                // Configure your logout URL and success URL here
                .tokenValiditySeconds(86400) // 1 day

In the example above, we have disabled Cross-Site Request Forgery (CSRF) protection for simplicity. However, CSRF protection should be enabled in a production environment.

To enable secure cookie configuration in your Spring Security application, you need to add the following lines to your or application.yml file:

# Session Cookie Configuration


# Session Cookie Configuration
        secure: true
        http-only: true

By setting to true, the session cookie will only be sent over a secure HTTPS connection. This prevents the cookie from being intercepted in transit by an attacker.

Similarly, setting server.servlet.session.cookie.http-only to true restricts the cookie to be accessible only through HTTP or HTTPS protocols. This prevents client-side scripts from accessing the cookie, protecting against potential cross-site scripting (XSS) attacks.


Implementing secure cookie configuration is an essential aspect of any web application that deals with sensitive user data. In this article, we discussed the steps required to configure secure cookies in a Spring Security application. By following these steps and understanding the importance of secure cookie configuration, you can enhance the security and integrity of your application. Remember to keep your dependencies up to date and regularly test your application for any security vulnerabilities. Stay secure!
