AWS Security: 10 Essential Best Practices
This article outlines ten foundational AWS security best practices for cloud engineers, covering identity and access management, encryption, network design, monitoring, secrets management, automation, and regular auditing. Key recommendations include avoiding daily use of the root account and enabling MFA, applying the principle of least privilege through fine-grained IAM policies, encrypting data-at-rest with AWS KMS and customer-managed keys, protecting public-facing resources via private subnets and security controls, and enabling continuous monitoring with services like CloudTrail, GuardDuty and Security Hub. It also advises storing secrets in managed stores (Secrets Manager, Parameter Store), using Infrastructure as Code (Terraform, CloudFormation, AWS CDK) to automate security checks, and scheduling regular reviews and audits to maintain a secure baseline.
Practical, actionable AWS security guidance useful for cloud engineers but not breaking news or industry-shifting.

Clear Guide to AWS Security and Storage
A dev.to technical post (published 2026-05-15) summarizes key AWS security and storage concepts aimed at AWS Cloud Practitioner exam takers and beginners. It explains AWS Config’s change recording and drift detection; distinguishes Shield Standard (free, L3/L4 DDoS protection) from Shield Advanced (paid, covers EC2, ELB, CloudFront, Route 53, Global Accelerator, includes DDoS Response Team and cost protection); and describes WAF’s L7 request-inspection capabilities and where it attaches (CloudFront, ALB, API Gateway, AppSync). The article compares WAF, NACLs, and Security Groups, contrasts EBS, EFS, S3 and Instance Store storage characteristics, highlights the Cost & Usage Report as AWS’s most granular billing feed, and lists five security services (Shield, WAF, GuardDuty, Inspector, Macie) with their primary jobs.
Seven Common AWS IAM Misconfigurations Identified
Shieldly published a technical blog post (originally on shieldly.io) that identifies seven recurring AWS IAM misconfigurations observed across many accounts. The article lists each unsafe pattern, explains why it is dangerous (e.g., privilege escalation, confused‑deputy risk, audit blindspots), and gives concrete remediation advice such as scoping actions/resources, requiring ExternalId for third‑party cross‑account roles, using managed policies instead of inline user policies, and restricting iam:PassRole and sts:AssumeRole to specific role ARNs. The post (published July 1, 2026) also points to Shieldly’s free AI-powered IAM policy analysis tool and includes a limited-time promo code.
Modern DevOps Guide to Architecting on AWS
This technical guide outlines modern DevOps practices for architecting reliable, scalable systems on AWS. It argues the DevOps role has shifted from console-driven sysadmin work to platform engineering—building automated, self-service internal developer platforms. Key recommendations include treating infrastructure as code using tools like Terraform, Pulumi, and the AWS CDK; adopting a multi-account strategy with AWS Organizations and Control Tower for isolation, security, and cost attribution; embedding security via automation (e.g., OIDC for CI/CD, continuous posture checks with Security Hub and GuardDuty); making cloud cost optimization an engineering metric (Graviton, VPC Endpoints, tagging); and improving observability with tracing tools such as AWS X-Ray or OpenTelemetry. The piece emphasizes developer experience via “golden paths” and self-service modules to maintain velocity while ensuring secure, compliant deployments.
