In the past year, 89% of organizations have faced at least one container or Kubernetes security incident, highlighting the importance of security for DevOps and security teams.
Despite concerns from many DevOps teams about Kubernetes’ security, it still dominates 92% of the container market. Gartner projects that by 2029, 95% of enterprises will be running containerized applications in production, a significant increase from less than 50% last year.
Misconfigurations account for 40% of incidents, with 26% of organizations admitting to failing audits. However, the fundamental weaknesses in Kubernetes security have yet to be fully addressed. Deciphering the multitude of alerts and identifying credible threats remains a critical challenge.
Kubernetes attacks are growing
Attackers are increasingly targeting Kubernetes environments due to unresolved misconfigurations and vulnerabilities. Red Hat’s recent report on Kubernetes security reveals that 45% of DevOps teams experience security incidents during the runtime phase, where live vulnerabilities are exploited.
The Cloud Native Computing Foundation’s Kubernetes report shows that 28% of organizations have insecure Kubernetes configurations for over 90% of their workloads. Additionally, more than 71% of workloads have root access, raising the risk of system compromises.
Traditional defense mechanisms are struggling to keep pace with attacks. Attackers can exploit weaknesses in Kubernetes security within minutes of discovery, while traditional security tools may take days to detect and address critical gaps.
As attackers become more sophisticated, organizations need real-time data to defend against Kubernetes attacks effectively.
Why alert-based systems aren’t enough
Most organizations that have adopted Kubernetes in their DevOps workflows rely on alert-based systems for container attack defense. Solutions from Aqua Security, Twistlock (now part of Palo Alto Networks), Sysdig, and StackRox offer threat detection, visibility, and vulnerability scanning. While these systems provide essential security features, they generate a large volume of alerts that can overwhelm security teams.
Laurent Gil, co-founder of CAST AI, emphasizes the need for automation in real-time threat detection and immediate remediation to address the flood of alerts and prevent alert fatigue among security professionals.
The goal: secure Kubernetes containers with real-time threat detection
Attackers are focusing on exploiting Kubernetes containers during runtime, where vulnerabilities such as misconfigurations and privilege escalations can be leveraged. The live nature of containers makes them attractive targets for crypto-mining operations and other large-scale attacks.
Citing real-world examples, CAST AI introduced their Kubernetes Security Posture Management (KSPM) solution to automatically detect and remediate security threats in real-time. This approach sets them apart by offering immediate fixes before issues escalate.
Ensuring the security of Kubernetes containers involves continuous scanning for misconfigurations, image vulnerabilities, and runtime anomalies. CAST AI’s KSPM solution emphasizes automated remediation to enhance security in complex environments.
Why Real-Time Threat Detection Is Essential
Real-time threat detection is crucial for combating Kubernetes attacks, particularly during runtime. The ability to automatically patch containers in real-time ensures systems are always secure and up-to-date.
Stepping up Kubernetes security is a must-have in 2025
With the increasing frequency of attacks on Kubernetes containers, organizations must prioritize security to protect against threats like crypto mining. Real-time monitoring and robust security controls are essential to safeguard against costly breaches.
