AWS Security Services: Secure your AWS infrastructure

We cover identity, network, data, and monitoring. That means strong IAM with least privilege and MFA, SSO where it helps, clean VPC design, private subnets, and sane security groups. For data, we set KMS keys, encryption in transit, and safe secrets storage. GuardDuty, Security Hub, CloudTrail, and Config keep watch and record changes. We add patching, backup rules, and playbooks for incidents. You get clear owners, weekly checks, and a short list of fixes that move risk down right away.

We start with least privilege and remove standing admin rights. Access goes through SSO and MFA, with short-lived credentials instead of long-lived keys. We group permissions by job function, add permission boundaries for safety, and use access analyzer to catch wide policies. For workloads, roles beat access keys. We log role use and rotate any remaining secrets. The result is a setup that’s safer day to day and still easy for engineers to get work done.

We segment networks by environment and sensitivity, use private subnets, and keep databases off the public internet. VPC endpoints limit traffic to AWS services without crossing the open web. For inbound paths, we place ALB/NLB in front, pair AWS WAF where needed, and keep security groups tight. We add GuardDuty for threat findings, Flow Logs for visibility, and Systems Manager for patching. If you need site-to-site links, we design VPN or Direct Connect with clear limits and monitoring.

Every account gets CloudTrail for API activity and Config to track resource drift. Metrics and logs land in CloudWatch with retention that matches your audit needs. We wire GuardDuty, Security Hub, and IAM Access Analyzer, then send only high-signal alerts to on-call. Low-value noise is muted or grouped. We build simple dashboards and weekly reports so owners can spot new risks, review changes, and confirm that backups, keys, and alarms are where they should be.

We turn on encryption with KMS keys, enforce bucket policies that block public reads, and add object ownership and versioning. Access goes through roles, not static keys. For databases, we use TLS, encrypted storage, and parameter groups that close risky features. Backups run on a schedule with cross-region copies and periodic restore tests. Lifecycle rules move old data to cheaper, encrypted tiers. We also flag PII locations and apply tighter access and logging around those stores.

Yes. We deploy AWS WAF with managed rules and targeted custom rules for your app paths. For DDoS resilience, we use CloudFront and AWS Shield protections. Secrets Manager or Parameter Store holds credentials with rotation. We review headers, TLS settings, and error handling on the edge. For CI/CD, we add checks for hardcoded secrets and block bad images from reaching production. Everything ties back to alerts with clear owners so issues are found and fixed quickly.

We build guardrails that map to common controls: least privilege, encryption, logging, retention, backup, and change tracking. Security Hub standards checks help prove control coverage. We document who can access what, how changes are approved, and where logs live. If you need HIPAA, we confirm BAAs, isolate PHI, and apply tighter monitoring. For GDPR, we add data location notes and delete flows. We don’t issue certifications, but we prepare the ground so audits go smoothly.

We create a runbook for the most likely cases: leaked keys, suspicious logins, malware on a host, or a risky bucket change. GuardDuty and CloudTrail findings feed a triage channel. We use tags and automation to isolate affected resources, rotate keys, and restore from known-good backups. Afterward, we review what happened, add missing alerts, and fix root causes. The goal is fast isolation, clean recovery, and a short list of concrete improvements you can ship right away.

We set up a landing zone with separate accounts for prod, staging, shared services, and security. Service control policies block risky actions at the top. Centralized CloudTrail and GuardDuty make it easier to see trouble across accounts. Identity goes through SSO with MFA and short sessions. Shared tooling (patching, backups, images) lives in one place, while teams work in their own accounts. This lowers blast radius and makes reviews and billing far clearer.
