10 Excellent Ways to Secure Your Spring Boot Application - The Secure Developer 2019

Spring Boot is an excellent way to build Java applications with the Spring Framework. If you’re developing apps that handle sensitive data, you should make sure they’re secure. This session will cover HTTPS, dependency checking, CSRF, using a CSP to prevent XSS, OIDC, password hashing, and much more! You’ll learn how to add these features to a real application, using the Java language you know and love.

1. 10 Excellent Ways to Secure Your Spring Boot Application June 6, 2019 Simon Maple and Matt Raible @sjmaple | @mraible thesecuredeveloper.com
2. 10 Excellent Ways… http://bit.ly/secure-spring-boot
3. 1. Use HTTPS in Production
4. Use HTTPS Everywhere! Let’s Encrypt offers free HTTPS certificates certbot can be used to generate certificates mkcert can be used to create localhost certificates Spring Boot Starter ACME for automating certificates
5. @Configuration public class SecurityConfiguration extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.requiresChannel().anyRequest().requiresSecure(); } }
6. @Configuration public class SecurityConfiguration extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.requiresChannel() .requestMatchers(r -> r.getHeader("X-Forwarded-Proto") != null) .requiresSecure(); } }
7. Life hack: Night lights
9. 2. Scan Your Dependencies for Vulnerabilities

13. Your Code Your App
14. Serverless Example: Fetch file & store in s3
 (Serverless Framework Example) 19 Lines of Code 2 Direct dependencies 19 dependencies (incl. indirect) 191,155 Lines of Code

16. Demo
17. 3. Upgrade To Latest Releases
19. How well do you know your dependencies?
20. Checking for Updates with npm npm i -g npm-check-updates
 ncu
21. Checking for Updates with Maven mvn versions:display-dependency-updates
22. Checking for Updates with Gradle gradle dependencyUpdates -Drevision=release
23. Life hack: Straight cuts
25. 4. Enable CSRF Protection
26. @EnableWebSecurity public class SecurityConfiguration extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .csrf() .csrfTokenRepository( CookieCsrfTokenRepository.withHttpOnlyFalse()); } }
27. 5. Use a Content Security Policy to Prevent XSS Attacks
28. @spring_io #springio17 Default Spring Security Headers Cache-Control: no-cache, no-store, max-age=0, must-revalidate Pragma: no-cache Expires: 0 X-Content-Type-Options: nosniff Strict-Transport-Security: max-age=31536000 ; includeSubDomains X-Frame-Options: DENY X-XSS-Protection: 1; mode=block
29. @EnableWebSecurity public class SecurityConfiguration extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.headers() .contentSecurityPolicy("script-src 'self' " + "https://trustedscripts.example.com; " + "object-src https://trustedplugins.example.com; " + "report-uri /csp-report-endpoint/"); } }

31. @spring_io #springio17 Better Web Site Security How-To developer.okta.com/blog/2019/04/11/site-security-cloudflare-netlify
32. Life hack: Peppermint tea
34. 6. Use OpenID Connect for Authentication
36. @spring_io #springio17 Spring Security OIDC Configuration spring: security: oauth2: client: registration: okta: client-id: {clientId} client-secret: {clientSecret} provider: okta: issuer-uri: https://{yourOktaDomain}/oauth2/default
37. OIDC Authentication Demo @Grab('spring-boot-starter-oauth2-client') @RestController class Application { @GetMapping('/') String home(java.security.Principal user) { ‘Hello ' + user.name } }
38. Works with Spring WebFlux developer.okta.com/blog/2018/11/26/spring-boot-2-dot-1-oidc-oauth2-reactive-apis
39. And JHipster! developer.okta.com/blog/2019/04/04/java-11-java-12-jhipster-oidc
40. 7. Managing Passwords? Use Password Hashing!
41. hash(“TSD”) = 3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3 hash(“TSD”) = 3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3 hash(“TSD”) = 3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3 hash(“TSD”) = 3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3 Deterministic
42. One-way function hash(“TSD”) =3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3 unhash(“3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3”) = ???
43. It should not be predictable hash(“TSD0”) = 3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3 hash(“TSD1”) = 98eadd540e6c0579a1bcbe375c8d1ae2863beacdfb9af803e5f4d6dd1f8926c2 hash(“TSD2”) = 665ec59d7fb01f6070622780e744040239f0aaa993eae1d088bc4f0137d270ef hash(“TSD3”) = 7ae89eb10a765ec2459bee59ed1d3ed97dbb9f31ec5c7bd13d19380bc39f5288
44. One to one mapping hash(“TSD”) = 3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3 hash(“123”) != 3c9c93e0f8eb2161e5787f7cd3e4b67f8d98fbd80b7d237cc757583b06daa3e3
45. @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } Hashed passwords in Spring
46. @Autowired private PasswordEncoder passwordEncoder; public String hashPassword(String password) { return passwordEncoder.encode(password); } Hashed passwords in Spring
47. Life hack: Pasta holder
49. 8. Store Secrets Securely
51. https://github.com/awslabs/git-secrets
52. <dependencies> <dependency> <groupId>org.springframework.vault</groupId> <artifactId>spring-vault-code</artifactId> <version>2.2.RELEASE</version> </dependency> </dependencies> Spring Vault
53. Spring Vault @Value(”${password}”) String password;
54. 9. Test Your App with OWASP’s ZAP
55. OWASP Zed Attack Proxy Two approaches: Spider and Active Scan Spider starts with a seed of URLs Active Scan records a session then plays it back, scanning for known vulnerabilities
56. Learn More about ZAP Homepage www.owasp.org/index.php/OWASP_Zed_Attack_Proxy_Project GitHub github.com/zaproxy/zaproxy Twitter twitter.com/zaproxy
57. Life hack: Boiling water
59. 10. Have Your Security Team do a Code Review
60. Code Review topics 1. Identify and validate any third party input 2. Never store credentials as code/config 3. Test for new security vulnerabilities in third-party open source dependencies. 4. Authenticate inbound requests 5. Enforce the least privilege principle 6. Prefer whitelist over blacklist 7. Handle sensitive data with care 8. Do not allow back doors in your code 9. Protect against well-known attacks 10.Statically test your source code on every PR, automatically
