DevNexus 2025: Celebrating Java’s Legacy and Embracing the Future of Enterprise Security

Atlanta, Georgia, a city steeped in history, recently hosted the 21st edition of DevNexus, the largest and longest-running Java community conference. This year’s event was particularly significant, coinciding with the 30th anniversary of the Java programming language. Over 1,200 developers, DevOps professionals, and open-source contributors gathered for three days of intensive workshops and presentations, focusing on innovation within the Java ecosystem. A recurring theme, reflecting industry trends, was the integration of AI to accelerate development and improve processes.

Java Security: The Cornerstone of Enterprise Security

Java’s enduring popularity in enterprise environments means its security directly impacts the overall security posture of organizations. With approximately 90% of Fortune 500 companies relying on Java for critical applications, securing this language is paramount.

Java played a pivotal role in the evolution of microservices architecture, offering scalable and modular solutions. Many contemporary software security challenges, including supply chain attacks, dependency management, API security, and workload isolation, have long been central to Java security discussions. Historical vulnerabilities, such as the infamous Log4Shell, highlighted the critical need for robust Java security practices across both cloud and on-premise systems.

Securing Secrets: A Top Priority in Java Development

Protecting sensitive information, or “secrets,” within Java applications is crucial, as these are prime targets for attackers. For instance, Neo4J, a widely used graph database written in Java and essential for building knowledge graphs in LLM applications, has seen a concerning rise in credential leaks on public code repositories. Compromised Neo4J credentials can allow attackers to manipulate these systems extensively.

Similarly, Keycloak, a popular open-source identity and access management (IAM) platform built with Java, is often used for single sign-on (SSO) and user federation. Leaked administrative API keys for Keycloak could grant attackers elevated privileges or even lock organizations out of their own systems. Protecting these secrets is absolutely essential.

Authentication and Authorization in Focus

Authentication and authorization were major topics at DevNexus, with multiple sessions dedicated to these critical security aspects. Discussions ranged from scaling secrets security to addressing the challenges of vault sprawl and long-lived credentials in legacy systems.

Several presentations provided practical guidance on implementing authorization within applications. For example, one session showcased various approaches to leveraging authorization within the Spring framework through code examples. Other sessions offered high-level introductions to concepts like OAuth2, explaining how it enables secure access to resources using identity and access tokens.

AI’s Growing Role in Enterprise Java Applications

The Java community is known for its adaptability, and the rapid adoption of AI is a testament to this. DevNexus reflected a cautious optimism about AI’s potential within the Java development ecosystem.

Numerous talks and workshops explored the intersection of Java and AI/LLMs. These sessions covered a range of topics, from AI-driven development techniques and AI tools for specific Java frameworks (like Jakarta EE) to building better AI using open-source tools.

Security-focused AI sessions addressed the legal and safety aspects of AI at scale. One presentation demonstrated common and easily executed attacks against AI chat agents, highlighting the potential for extracting sensitive data, including secrets, from training data. The session also provided valuable remediation advice, emphasizing the importance of human oversight and limiting the scope of access for AI agents, mirroring best practices for credential security.

A Thriving Community and a Secure Future

While newer languages are emerging, Java remains the preferred choice for enterprises prioritizing scalability and reliability. Its widespread use across major corporations underscores the ongoing need for developers skilled in building and deploying secure Java applications.

The vibrant and welcoming Java community, exemplified by DevNexus, is a valuable resource for developers. Hundreds of Java User Groups (JUGs) worldwide offer support and learning opportunities for those looking to enhance their Java skills.
