DevSecOps Troubleshooting Cheat Sheet: Log, Security, Kubernetes, Cloud Fixes

Practical Cloud Security at the Platform Layer 🔐 In large-scale Azure and Kubernetes environments, security isn’t just an afterthought — it’s part of the platform design. Here’s a simple, visual reminder of what I focus on when building secure-by-default DevOps platforms 👇 🧩 RBAC – Enforce least privilege roles for every identity and service. 🔑 Workload Identity – Remove long-lived secrets and rotate tokens automatically. 🌐 Segmentation – Apply network policies and private links to minimize lateral movement. 🗝️ Secrets – Centralize secrets in Key Vault and rotate them regularly. 🧱 Image Hygiene – Use signed, scanned base images for every deployment. ⚙️ Policy Guardrails – Prevent non-compliant deployments at the pipeline or IaC stage. The goal isn’t perfection — it’s predictable, auditable control that scales with every release.

Week 5 | Cloud Automation and DevSecOps – Strengthening Security and Deployment Practices Designed and tested a secure CI/CD pipeline workflow that integrates automated build, vulnerability scanning, and deployment steps. Practised using Trivy to scan container images, infrastructure-as-code files, and source directories for vulnerabilities and misconfigurations. Reviewed how security can be integrated early in the development process through static analysis, dependency scanning, and policy validation. Learned how AWS Config can enforce security baselines and compliance policies across cloud environments. Automated alerts using CloudWatch and a simple Lambda function to simulate real-time security notifications. Explored secure secret handling through AWS Secrets Manager and KMS encryption to prevent credential exposure and strengthen key management practices. These hands-on exercises helped me understand how automation and security work together in cloud environments. Building secure pipelines taught me the importance of early detection, consistent policy enforcement, and strong operational discipline in real-world cloud deployments. Reflection: Maintaining this weekly learning commitment alongside my academic and project responsibilities continues to reinforce the importance of self-discipline and intentional technical development. DevSecOps has shown me how crucial it is to embed security principles into every stage of the development and deployment process, not just at the end. #CloudEngineer #DevSecOps #CI/CD #CloudAutomation #CloudSecurity #AWS #Azure #GoogleCloud #InfrastructureAsCode #SecurityEngineering #CloudComputing #SelfLearning #CareerLaunch #APU #Malaysia

As cloud engineers, we understand the rapid pace of CI/CD environments and the tendency for security to lag behind. However, integrating security early into DevOps can make a significant impact. Here are some effective strategies from my experience: - Implement strong IAM policies, focusing on least privilege, short-lived credentials, and continuous audits. - Encrypt everything—data in transit, at rest, and even between internal services. - Automate security checks in your pipelines, including IaC scans, dependency checks, and secret detection. When security is woven into your workflow rather than acting as a bottleneck, you can ship faster and safer. How are you embedding security into your cloud pipelines?

SSL management in k8s is a must-know workflow for DevOps engineers. In every project, You will have to deal with TLS certificates. It could be public or internal certificates. One of the best ways to manage SSL in Kubernetes is by using cert-manager. It automates the entire process of managing TLS certificates. It supports many certificate providers, also called issuers. For example: - Let’s Encrypt – a free, public certificate authority - HashiCorp Vault – can act as an internal certificate authority - Self-signed or internal PKI – cert-manager can create self-signed certs or work with a custom CA In enterprise setups, many organizations have their own certificate authority. cert-manager can easily integrate with these systems to issue trusted certificates. Over to you! Do you have experience managing SSL using cert manage or any other tool?

What is DevSecOps? Today I’m beginning my learning and sharing journey in AWS DevSecOps 🚀 DevSecOps stands for Development + Security + Operations. It means Security is integrated in every step of the DevOps pipeline — not just at the end. Why is DevSecOps important? -->Security is everyone’s responsibility -->It prevents vulnerabilities early -->It reduces cost & risks -->It helps in releasing software faster and safer Old way: Code → Build → Test → Deploy → Then Security Check DevSecOps way: Security is added at each stage ✔️ I will be sharing my daily learning journey in simple, clear, beginner-friendly posts. Let’s grow together 🤝 #DevSecOps #AWS #DevOps #LearningJourney #Cloud #Security

Last week, I came across a small but important issue while setting up a CI/CD pipeline — credentials were being stored directly in the pipeline script. 😬 At first, it felt convenient — everything worked smoothly. But then it hit me: if anyone gets access to that repo, they basically get access to our entire environment. 💡 The Fix: We moved all sensitive data (API keys, passwords, tokens) to a secure secret manager — in this case, AWS Secrets Manager, but tools like Vault or GitHub Actions Secrets work just as well. Now, the pipeline pulls secrets dynamically at runtime — no more plain-text credentials floating around. This small change improved our security posture massively — and reminded me that in DevOps, speed means nothing without security. Curious to know — what’s the most common DevSecOps mistake you’ve seen in your projects? #DevOps #Security #DevSecOps #Cloud #Automation #CICD

🤔 codifying governance and compliance rules ---> Policy as Code (PaC) the same way we codify infrastructure with Terraform or configuration with Ansible. Instead of enforcing security, compliance, or operational policies manually or through the portal, you write those policies in code, version-control them, and automate their deployment via CI/CD pipelines. It ensures: 👉 Consistency across environments (dev, test, prod) 👉Auditability and traceability 👉Automated enforcement (no manual intervention) ➡️ Policy as Code in Azure: The Core Building Block --> Azure Policy Azure provides Azure Policy, a native governance engine that: Defines rules about what can/can’t be deployed Audits or denies non-compliant resources Applies at subscription, management group, or resource group scope 🛞 Example: A policy might say: “Only allow virtual machines in the ‘East US’ region.” Azure Policy evaluates all resource deployments and flags or blocks those that break the rule. 🧭 Policy as Code vs Security as Code Policy as Code --> defines what is allowed or denied Security as Code --> defines how systems stay secure (firewalls, identity rules, access controls) Together, they form the backbone of a secure and compliant cloud foundation. Governance deserves the same DevOps discipline as infrastructure. Policy as Code isn’t just a best practice, it’s how modern cloud platforms stay secure, compliant, and scalable. How are you approaching governance as code in your cloud setup, are you using Azure Policy with terraform, OPA, or something else? 🤔 #Azure #DevOps #PolicyAsCode #Cloud #AWS #GCP #Platform #Computing #DevSecOps #CloudEngineering #MicrosoftCloud #SecurityAsCode #Security #CloudSecurity
