问题 In a Spring Boot project we enabled Spring Security and applied Keycloak authentication with bearer token like described in the following articles: https://www.keycloak.org/docs/3.2/securing_apps/topics/oidc/java/spring-security-adapter.html https://www.keycloak.org/docs/3.2/securing_apps/topics/oidc/java/spring-boot-adapter.html But i can't find any recommendations how to make automation tests so that the Keycloak config is applied. So, how to test/mock/verify the Keycloak configuration when

问题 I'm setting up a webapp with a frontend and a backend that communicates with the frontend soley through RESTful methods. How do I make sure that the backend endpoints are only accessed by my own frontend, and not anyone else? I cannot find much information on this. 回答1: How do I make sure that the backend endpoints are only accessed by my own frontend, and not anyone else? Let me tell you here a cruel truth... is not possible for a web app, due to the nature how the web was designed to work.

问题 Is it safe to share 2FA codes? I'm talking about TOTP like Google Authenticator or Authy . For example, if i have code and generation time, is it possible to predict new codes? What if i have more than 1 pair of code+time? I think it's possible to predict new codes based on old information (code+time). So if this is possible, how do I do it? Im looking for some algorithm. Known Time period, time, code and secret length. Example: 22:20:30 561918 22:21:00 161664 22:21:30 610130 回答1: Internally,

问题 We have a classical C-S(client-server) architecture, i.e. a mobile app and a business server. We have our own account system (not using 3rd party accounts such as Google/Facebook account). I know I should use OAuth2 for authentication. The problem is, how shall I implement that ? There are two things that I did not found on the Internet: We are using our own account system - no Google/Facebook account. The user should input his password in the native app UI, not in a browser webpage embedded

问题 I want to add the httponly and secure flags for Cookies. To implement it, I am using Filters which are configured in web.xml .

问题 I'm new to Elastic search. Integrated my Spring boot application with Elastic search through Java High Level Rest Client . I've configured JHLRC bean as below and it worked fine: @Bean(destroyMethod = "close") public RestHighLevelClient client() { RestHighLevelClient client = new RestHighLevelClient( RestClient.builder(new HttpHost("localhost", 9200, "http"))); return client; } Started exploring the security for Elasticsearch, after setup certificate and passwords, I've enabled security by
