Implementing security at the Java virtual machine level.
Course schedule
1 Fundamentals of Java application security
- Introduction to the JVM.
- Use of recent Java versions (Java 17+).
- Bytecode and obfuscation.
- Maven dependency management and library vulnerability detection.
- Set up a secure logging system (e.g. SLF4J, Logback or Log4J).
2 Authentication management
- Various authentication methods (password, biometric, digital key, etc.).
- Use of the OAuth 2.0 standard for modern access management.
- JWT (JSON Web Tokens) for secure session management.
- Multi-factor authentication (MFA).
- Integration of an identity provider.
Hands-on work
Mise en place d'un processus d'identification par mot de passe, d'une clé d'API et d'un token JWT avec Keycloak.
3 Access control and authorization
- Principle of least privilege in applications.
- Use of RBAC (Role-Based Access Control).
- Implementation of access controls in applications. (Spring Security).
Hands-on work
Setting up a secure section based on the principle of least privilege with Spring Security.
4 Using SSL/TLS
- Use SSL/TLS to secure communications.
- Secure configuration of database connections (use of SSL/TLS to connect to MySQL/PostgreSQL).
- Self-signed certificate generation with Java KeyStore.
Hands-on work
Generate a self-signed certificate with KeyStore and host an application with SSL.
5 Data security
- SQL Injection : comment les éviter (utilisation des Prepared Statements, ORMs comme Hibernate).
- Encryption of sensitive data in the database.
- Database access management (separation of roles and privileges).
- Secure password management (storage with algorithms such as MD5, SHA256 or bcrypt).
Hands-on work
Création d'une base de données stockant des mots de passe chiffrés, connexions utilisateurs et utilisation de requêtes préparées.
6 Modern, secure infrastructures
- The different HTTPS certificates.
- Zero trust models.
- Java security in containers.
- SIEMS.
- The CORS protocol.
- Secure architectures by design.
7 Different types of attack
- Never Trust User Input validation.
- Secure RESTful APIs with headers such as Authorization and X-XSS-Protection.
- SQL injections.
- XSS and user input cleaning.
- CSRF (Cross-Site Request Forgery): implementation of anti-CSRF tokens.
Hands-on work
User data cleansing with OWASP.
