Java Services Face High Security Risks, DevSecOps Must Adapt

The importance of cybersecurity in software development is underscored by recent findings reported in Datadog’s State of DevSecOps. Java services in production are highlighted as especially vulnerable, with an alarming 90% containing at least one vulnerability of critical or high severity—a figure that starkly surpasses the 47% average seen in services using other programming languages. The main contributors to this high vulnerability rate are indirect dependencies. These are the secondary libraries that are incorporated alongside the directly used ones. They account for 63% of the identified security risks. This trend points to a pressing need for better security practices and more stringent management of both direct and indirect dependencies within the Java development ecosystem to mitigate potential cyber threats.

The Third-Party Library Quandary

Third-party libraries are ubiquitous in modern software development due to their efficiency in providing out-of-the-box functionality. However, they also pose serious security risks. For Java services, the reliance on these libraries makes them more susceptible to vulnerabilities, many of which are critical or high in severity. Despite the known risks, these libraries remain integral to Java applications. The indirect nature of many dependencies complicates their tracking and update process, thereby amplifying the security risk. Developers might patch direct dependencies, but often these indirect, or transitive, dependencies are left unchecked, providing a backdoor for attackers.

What’s more alarming is the potential impact of the Known Exploited Vulnerabilities (KEV) catalog by CISA. Java applications are disproportionately targeted, with 55% of these known vulnerabilities affecting Java platforms. This is in stark contrast to the mere 7% affecting other languages, pushing to the forefront the need for Java services to be more diligently scrutinized and secured.

The Need for a Paradigm Shift

DevSecOps must evolve to tackle vulnerabilities more adeptly. Currently, many organizations depend on “ClickOps”—manual protocols for security review and troubleshooting—which are not as swift as automated systems. These practices can cause delays in updating defenses, exposing systems unnecessarily. Transitioning towards automated and continual processes like CI/CD can enhance the speed and efficiency of vulnerability management.

A key step beyond just finding security flaws is accurately gauging how dangerous they are. Tools such as the Exploit Prediction Scoring System (EPSS) prove vital in reassessing the danger level of identified vulnerabilities. Notably, over half of the services initially marked with critical vulnerabilities were downgraded in threat level upon re-evaluation with EPSS. Such precise prioritization helps organizations focus on truly critical issues, optimizing resource allocation for enhanced security measures.

Prioritization and Streamlining Are Key

Recent analysis suggests that when it comes to vulnerability management, factors such as exploitability and context are key, not just severity. Interestingly, a link was found between container size and security—smaller containers generally have fewer vulnerabilities due to fewer components. This highlights the need for a strategic approach to vulnerability management.

Security teams, however, face challenges with scanner tools that can overwhelm them with alerts, including both critical and less impactful vulnerabilities. This situation risks essential threats being missed due to alert fatigue.

Therefore, it’s imperative that DevSecOps practices evolve. Automating security processes, reassessing vulnerability criticality, reducing container sizes, and managing alerts effectively are vital steps for safeguarding Java services in production. Execution of these strategies will enable organizations to strengthen their defense mechanisms in a constantly evolving security ecosystem.
