New vulnerabilities in Chaos Mesh have shown just how quickly a Kubernetes cluster can be put at risk. According to CSO, these flaws could even enable a full cluster takeover. That’s not just a bug fix issue, it’s a reminder that even trusted tools in the ecosystem can expose hidden entry points. 🔑 The lesson? Security in Kubernetes is never “set it and forget it.” Stealth threats demand proactive measures, not reactive panic. 💡 What helps: Regularly audit dependencies and integrations Prioritize visibility across your cluster Treat third-party tools with the same scrutiny as core infrastructure The reality: Kubernetes is powerful, flexible, and fast-moving, but that pace means blind spots can creep in without warning. Staying ahead requires both vigilance and the right systems in place. Do you think teams underestimate how much third-party tools impact Kubernetes security? #Kubernetes #DevOps #ChaosMesh #CyberSecurity

Keeping your dependencies secure at scale? Hard. Automating the triage so your team only sees the high-risk stuff? Much smarter. Here’s how Nurse Betty helps Rewind prioritize the right security issues—and how you can too. 🔗 Read the blog: https://lnkd.in/g_KtzPUJ #DevOps #DevSecOps #CyberSecurity #Automation

Most teams track controls. Few prove behavior. Configurations prevent mistakes. Activity reveals intent. DataDefender lets you see storage activity as it happens, tie actions to identities across accounts, and step in before exfiltration or insider misuse becomes an incident. Keep your stack for data in motion. Add activity monitoring for data at rest.

You’re securing your Kubernetes cluster wrong if you’re just leaning on RBAC and network policies! Standard practices won’t cut it in a world of supply chain attacks and insider threats. Discover three uncommon strategies to lock down your cluster like a fortress. Kubernetes clusters are a hacker’s playground—dynamic pods, sprawling APIs, and misconfigurations galore. While RBAC and pod security standards are table stakes, they miss subtle threats like lateral movement or runtime exploits. Enter three game-changing, underused strategies. First, deploy a service mesh like Istio for zero trust. Istio enforces mutual TLS (mTLS) and fine-grained authorization between services, ensuring every pod-to-pod call is verified. Set it up with istioctl install and define AuthorizationPolicy to restrict access—perfect for microservices. Next, embrace eBPF-based runtime security with tools like Falco or Cilium. eBPF monitors kernel-level activity, catching anomalies like unauthorized container execs or file changes in real-time. Install Falco with Helm and configure rules to alert on suspicious syscalls, giving you a proactive defense layer. Finally, leverage OpenTelemetry for security observability. Beyond performance, OpenTelemetry’s traces and metrics reveal security threats, like unexpected API calls or latency spikes from attacks. Instrument your apps with the OpenTelemetry SDK and export to Jaeger or Prometheus for real-time threat detection. These strategies—service mesh, eBPF, and observability—supercharge your cluster’s security, aligning with zero trust by assuming breach and verifying everything.

Container Orchestration Security Your Kubernetes clusters might be your biggest blind spot. The Reality: 40% of organizations don't have proper RBAC configurations in their K8s environments. That's like leaving your front door wide open. The Threat: Misconfigured pod security policies + weak RBAC = lateral movement paradise for attackers. The Fix: Implement proper Kubernetes RBAC, service mesh security, and pod security standards from day one. TrustAxis delivers secure Kubernetes deployments that achieve 40% faster deployments without compromising security. We configure RBAC, implement policy controls, and integrate with your CI/CD pipeline. Secure your containers before attackers do. https://trustaxisinc.com #Kubernetes #K8s #ContainerSecurity #DevSecOps #RBAC #CloudNative #TrustAxis #K8sSecurity #ServiceMesh #PodSecurity #Cybersecurity

🔐 Common Cyber Attacks in DevSecOps In DevSecOps, security is embedded into the DevOps lifecycle — which means we need to protect not only the code but also pipelines, containers, and infrastructure. Here are some of the most common attack vectors: ✅ Code & App Layer → SQL Injection, XSS, Dependency Attacks ✅ Source Control → Secret Leakage, Supply Chain Attacks, Malicious Commits ✅ CI/CD Pipelines → Pipeline Poisoning, Privilege Escalation, Artifact Tampering ✅ Containers & Kubernetes → Container Escape, Misconfigurations, DoS Attacks ✅ Cloud & IaC → Misconfigured IAM/S3, Exposed APIs, Vulnerable IaC Modules 🛡️ Tools like Trivy, SonarQube, Checkov, OPA, Vault, and Falco can help mitigate these risks and strengthen your DevSecOps practices. 👉 Security is not a stage — it’s part of every step. #DevSecOps #CyberSecurity #CloudSecurity #Kubernetes #CICD

Happy #FriYay: Secure Code Release! 😎  Tip for a Safe Weekend: Security is not a final checkpoint; it's a continuous phase embedded right into your pipeline! Embed security checks (like static code analysis) directly into your CI/CD pipelines to ensure every release is robust and helps users #StaySafeOnline. That's #DevSecOps for the win! 🚀 Learn to integrate security seamlessly from our practitioner-trainers at Sapience Consulting! https://lnkd.in/gjpWKXHh #DevOps #Cybersecurity #SecureDevelopment #ExperienceExceptional

🚨 Top Cybersecurity Risks in DevSecOps (Past Year) 🚨 As DevSecOps evolves, organizations face new threats that can compromise the entire software delivery pipeline. The most common risks seen over the last year include: 1️⃣ Software Supply Chain Attacks – malicious code hidden in third-party libraries or tools. 2️⃣ Cloud & IaC Misconfigurations – open storage, over-permissive permissions, weak network rules. 3️⃣ Poor Secrets Management – API keys, tokens, or passwords exposed in code or repos. 4️⃣ Outdated / Vulnerable Dependencies – unpatched libraries introducing critical risks. 5️⃣ Insufficient Security Testing – vulnerabilities reaching production due to speed over security. 🔐 The key to DevSecOps success is shifting security left, integrating testing early, and continuously monitoring every stage of the CI/CD pipeline. #DevSecOps #CyberSecurity #CloudSecurity #SoftwareSupplyChain #BrazilTech
