Course Outline

1. IT security and secure coding

  • Fundamental Security Principles: Exploring Confidentiality, Integrity, and Availability (CIA) specifically within Java application contexts.
  • Secure Software Development Lifecycle (SSDLC): Embedding security considerations from the requirements phase through to deployment.
  • Secure Coding Paradigms: Implementing defense in depth, least privilege, and fail-safe defaults.
  • Standard Vulnerability Classifications: Interpreting the Common Weakness Enumeration (CWE) and OWASP standards.

2. Web application security

  • Deep Dive into OWASP Top Ten: In-depth analysis of Injection, Broken Authentication, and Sensitive Data Exposure.
  • Cross-Site Scripting (XSS): Examining Reflected, Stored, and DOM-based XSS scenarios in Java/JSP environments.
  • Cross-Site Request Forgery (CSRF): Understanding attack mechanisms and the implementation of Anti-CSRF tokens.
  • Session Management: Enhancing cookie security, preventing session fixation, and managing timeouts effectively.
  • API Security: Protecting REST and SOAP endpoints from abuse.

3. Security of Web services

  • Web Services vs. Traditional Web Apps: Distinguishing the differences in attack surfaces.
  • Transport Layer Security: Configuring SSL/TLS for Java clients and servers.
  • Message Security: Ensuring Integrity and Confidentiality at the payload level.
  • Authentication Standards: Implementing OAuth 2.0, OpenID Connect, and JWT (JSON Web Tokens).

4. XML security

  • XML Parsing Vulnerabilities: Strategies to prevent XML External Entity (XXE) attacks.
  • XML Schema Validation: Best practices for enforcing strict schema compliance.
  • XML Digital Signatures: Utilizing signatures to ensure non-repudiation.
  • XML Encryption: Standard methods for encrypting XML content.

5. Foundations of Java security

  • The Java Security Architecture: Exploring the java.security package and its provider architecture.
  • Security Providers: Procedures for installing and configuring providers such as Bouncy Castle.
  • Access Control: Managing policy files, Permissions, and the Security Manager (comparing legacy and modern approaches).
  • KeyStore Management: Creating and maintaining keystores and truststores for certificate management.

6. Practical cryptography

  • Cryptographic Algorithms: An overview of Symmetric (AES), Asymmetric (RSA, ECC), and Hashing (SHA-256/512) algorithms.
  • Random Number Generation: Understanding the risks associated with java.util.Random compared to java.security.SecureRandom.
  • Key Management: Strategies for key generation, secure storage, and rotation.
  • Java Cryptography Architecture (JCA): Leveraging the Cipher, MessageDigest, and Mac classes.
  • Java Cryptography Extension (JCE): Understanding policy files and unlimited strength jurisdiction.

7. Java security services

  • SSL/TLS in Java: Utilizing SSLSocketFactory and HttpsURLConnection.
  • Trust Managers: Customizing trust verification for private PKI environments.
  • Authenticators: Implementing programmatic authentication using Authenticator.getDefault().
  • Certificate Parsing: Programmatically reading and analyzing X.509 certificates.

8. Java EE security

  • Declarative Security: Implementing Role-based access control (RBAC) via web.xml and annotations.
  • Programmatic Security: Utilizing HttpServletRequest.isUserInRole() and getRemoteUser().
  • JAAS (Java Authentication and Authorization Service): Configuring login.conf and implementing LoginModules.
  • Servlet Security: Applying container-managed security constraints and authentication methods (FORM, BASIC, DIGEST).

9. Common coding errors and vulnerabilities

  • Insecure Deserialization: Assessing the risks of ObjectInputStream and bypassing security checks.
  • Command Injection: Mitigating vulnerabilities related to OS-level execution.
  • Path Traversal: Sanitizing file system inputs to block directory traversal.
  • Reflection Abuse: Evaluating risks associated with java.lang.reflect and bypassing access control.
  • Hardcoded Credentials: Identifying and removing secrets from source code.
  • Cryptography Implementation Errors: Avoiding the use of ECB mode, weak keys, or static IVs.

10. Knowledge sources

  • Static Analysis Tools: Utilizing SonarQube, Checkmarx, and Fortify for automated scanning.
  • Dynamic Analysis Tools: Overview of Burp Suite and OWASP ZAP.
  • CVE Databases: Methods for tracking and responding to new Java framework vulnerabilities.
  • Recommended Readings: Curated list of books, documentation, and secure coding checklists.
