For adding a Spring Boot Security to your Spring Boot application, we need to add the Spring Boot Starter Security dependency in our build configuration file. Content Security Policy Another modern approach to dealing with clickjacking is using a Content Security Policy. Accordingly, some browsers support X-Frame-Options and some Content-Security-Policy. A website specifies a CSP using an HTTP header sent from the server. That's because Spring Boot is configured to permit surpassing the auto-configured security by adding in our new/custom configuration classes. Apply Spring Boot Filter based on URL Pattern Once you create a filter in Spring Boot and annotated with @Component annotation,it will automatically identified by Spring Boot.In some cases you many want to apple the Spring Boot filter based on a certain URL pattern and not for every request. We know the code is trusted. Spring @EnableWebSecurity Example. 1 2 3 4 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> Extending WebSecurityConfigureAdapter Next, create a class that extends the WebSecurityConfigureAdapter. That's the header you should use. Poor code quality leads to unpredictable behavior. If an Angular app or any other web app contains an XSS vulnerability, the browser may understand arbitrary code injected by a malicious user as valid code and execute it. - access Token & refresh Token are stored in the HttpOnly Cookies: - Access resource successfully with access Token (in HttpOnly Cookie).

Solution 1 It's "working" in IE because IE doesn't support CSP headers, so it just ignores the policy and loads everything. Here are some requests to the endpoints that our Spring Boot Security JWT Refresh Token example exports. And here, we can do this to specify our application's credentials with the following properties: 1 2 spring.security.user.name spring.security.user.password 4.
