1# new AWS accounts need love 💚 Three critical steps: 1. Enable MFA for Root account 2. Use AWS IAM 3. Enable AWS Cloud Trail 3 @bruno_amaro

#2 Make Cost management a priority • Enable AWS Budgets & Billing Alarms • Use AWS Cost Explorer (or similar) • Cloud costs as part of the technology governance • Give cost visibility to the development team https://iamondemand.com/blog/how-to-get-the-most-out-of-the-aws-cost-management-tools/ 4 @bruno_amaro

#3 Lack of Multi-Account Governance • Ownership • Limit incident blast radius • Healthy service limits • Set Guardrails and a Landing Zone • Define Service Control Policies • Consolidated billing 5 @bruno_amaro

#4 Missing Infrastructure as Code practices • Re-deployable infrastructure • Scalable • Documented • Maintainable https://speaking.brunoamaro.com/yUeFUQ/deployment-automation-for-an-awsserverless-project-sam-vs-cloudformation-vs-terraform 6 @bruno_amaro

#5 Not using IAM properly • Users == Humans or non-AWS resources • Least privilege policies • Avoid using Inline and AWS managed policies • Use AWS SSO > IAM Roles if possible • Leverage AWS IAM Access Analyzer 7 @bruno_amaro

#6 Encryption & Secrets • Big impact on increasing security • Minimal cost impact (time and operational) • Compliance 8 @bruno_amaro Photo by Jordan Hopkins on Unsplash

#7 Missing out on interesting data Out-of-the-box data: • AWS Cloudtrail • AWS VPC Flow Logs • AWS ELB Access Logs Use cases: • Troubleshooting • Auditing & Compliance https://aws.amazon.com/guardduty/ • Analytics • SIEM 9 @bruno_amaro
