Kubernetes Security Hardening and CIS Benchmarks Implementation
Kubernetes security hardening involves implementing controls across the cluster, nodes, and workloads. The CIS Kubernetes Benchmark provides a comprehensive framework for securing Kubernetes deployments. This guide covers practical implementation of these security controls. CIS Benchmark Categories Control Plane: API server, controller manager, scheduler, etcd Worker Nodes: Kubelet, container runtime configuration …
Cloud Data Loss Prevention (DLP) and Encryption Best Practices
Data Loss Prevention and encryption are critical controls for protecting sensitive information in cloud environments. This guide covers implementing DLP policies, encryption strategies, and key management best practices across major cloud providers. Data Classification Before implementing DLP, classify your data into categories: Public: No restrictions on access Internal: Business data, …
Service Mesh Security and Zero Trust Networking with Istio
Service meshes like Istio provide a dedicated infrastructure layer for handling service-to-service communication. They enable zero trust networking by implementing mutual TLS, fine-grained access control, and observability without changing application code. Zero Trust Principles in Service Mesh Never Trust, Always Verify: Authenticate every request Least Privilege Access: Explicit authorization policies …
Container Escape Vulnerabilities and Mitigation Strategies
Container escapes occur when an attacker breaks out of a container’s isolation to access the host system or other containers. Understanding these vulnerabilities and implementing proper mitigations is critical for container security. Common Escape Vectors Privileged Containers: Running with –privileged flag disables security features Dangerous Capabilities: CAP_SYS_ADMIN, CAP_NET_ADMIN enable escape …
Cloud Identity and Access Management (IAM) Best Practices
Identity and Access Management is the foundation of cloud security. Properly configured IAM policies prevent unauthorized access and limit the blast radius of security incidents. This guide covers essential IAM best practices for AWS, Azure, and GCP. Principle of Least Privilege Grant only the minimum permissions required for users and …
Infrastructure as Code (IaC) Security Scanning: Shift-Left Your Cloud Security
Infrastructure as Code security scanning identifies misconfigurations and vulnerabilities in Terraform, CloudFormation, Kubernetes manifests, and other IaC templates before deployment. This shift-left approach prevents security issues from reaching production environments. Why IaC Security Matters Studies show that over 70% of cloud breaches result from misconfigurations. By scanning IaC templates during …
Cloud Workload Protection and Runtime Security: Defending Your Cloud Assets
Cloud Workload Protection Platforms (CWPP) provide security for workloads running in cloud environments, including virtual machines, containers, and serverless functions. Runtime security adds real-time threat detection and response capabilities to protect against active attacks. CWPP Core Capabilities Vulnerability Management: Continuous scanning of workloads for known CVEs Configuration Assessment: Hardening checks …
Serverless Security: Protecting Function-as-a-Service Workloads
Serverless computing with AWS Lambda, Azure Functions, and Google Cloud Functions introduces unique security challenges. While the cloud provider manages infrastructure security, application-level vulnerabilities and misconfigurations remain the customer’s responsibility. Serverless Attack Surface Unlike traditional applications, serverless functions have an expanded attack surface including event triggers, function code, dependencies, and …
Cloud-Native Application Protection Platforms (CNAPP): Unified Security for Modern Apps
Cloud-Native Application Protection Platforms (CNAPP) represent the convergence of multiple cloud security capabilities into a unified solution. As applications become more distributed across containers, serverless functions, and microservices, CNAPP provides comprehensive protection throughout the application lifecycle. Understanding CNAPP CNAPP combines Cloud Security Posture Management (CSPM), Cloud Workload Protection Platform (CWPP), …
Multi-Cloud Security Posture Management (CSPM): A Complete Guide
As organizations increasingly adopt multi-cloud strategies, maintaining consistent security across AWS, Azure, and GCP becomes a significant challenge. Cloud Security Posture Management (CSPM) tools have emerged as essential solutions for identifying misconfigurations and compliance violations across cloud environments. What is CSPM? CSPM continuously monitors cloud infrastructure for gaps in security …
What Are Cloud Security Applications?
Cloud security applications are tools that help protect information, programs, and systems stored in the cloud. These tools keep sensitive data safe and make sure only the right people can access it. As more companies use cloud technology, these applications have become super important to stop bad actors from causing …
