AWS Security Services

AWS environments: including IAM for AWS, AWS identity management, grow fast and misconfigurations accumulate faster. Overly permissive IAM roles, public S3 buckets, unencrypted data, and disabled logging are the most common findings in AWS security assessments: and the most exploited. garrisonOne assesses, hardens, and monitors AWS environments against real attack patterns.

AWS IAM Security Assessment & Hardening

AWS IAM Security Assessment & Hardening

AWS IAM is the most common source of cloud security failures. We assess IAM policies, roles, and trust relationships for overly permissive access, privilege escalation paths, cross-account trust issues, and unused credentials. Remediation includes least-privilege IAM policies, SCP guardrails, and IAM Access Analyzer configuration.

S3 Bucket Security & Data Exposure

S3 Bucket Security & Data Exposure

Public S3 buckets remain among the most common causes of enterprise data breaches. We audit every bucket's ACL, bucket policy, public access block settings, encryption configuration, and access logging. We identify data exposure paths that organizations frequently overlook: including resource-based policies and cross-account access.

AWS Security Hub & GuardDuty Configuration

AWS Security Hub & GuardDuty Configuration

AWS Security Hub aggregates findings across services. GuardDuty detects threats using machine learning and threat intelligence. We enable, configure, and tune these services: connecting them to your SIEM or SOC workflow so findings are actually acted on rather than sitting in a console nobody checks.

CIS AWS Benchmark Assessment

CIS AWS Benchmark Assessment

The CIS Foundations Benchmark for AWS provides a prescriptive set of security configurations across IAM, logging, monitoring, networking, and storage. We assess your environment against the benchmark, document each finding with remediation steps, and implement the required configuration changes.

AWS Compliance: SOC 2, PCI DSS, HIPAA

AWS Compliance: SOC 2, PCI DSS, HIPAA

Cloud environments have specific compliance requirements beyond on-premises controls. We assess your AWS environment against the controls required for SOC 2, PCI DSS, and HIPAA: covering encryption, access logging, network segmentation, and the specific AWS service configurations each standard requires.

Secure AWS Architecture Review

Secure AWS Architecture Review

New AWS deployments should be reviewed against security best practices before workloads go live. We review infrastructure-as-code (Terraform, CloudFormation) and AWS architecture for security design flaws: VPC configuration, security group rules, public subnet placement, and secrets management: before they become production problems.



What Makes Us Different From Others

AWS Security Services
  • IAM Privilege Escalation Analysis Most AWS assessments check for publicly accessible resources. We also enumerate IAM privilege escalation paths: the attack chains that let low-privilege accounts reach administrative access.
  • Infrastructure-as-Code Review We review Terraform and CloudFormation before deployment so misconfigurations are caught in code, not in production.
  • GuardDuty + Security Hub Tuning We configure and tune AWS-native detection tools so they are actually generating actionable alerts, not noise.
  • Compliance Evidence Package Every AWS assessment produces evidence artifacts mapped to specific SOC 2, PCI DSS, or HIPAA controls: ready for your next audit.
  • Remediation Included We do not just produce findings lists. Technical remediation of identified misconfigurations is included in our AWS security engagements.

Frequently asked questions

What are the most common AWS security misconfigurations?

The most commonly exploited AWS misconfigurations are: overly permissive IAM roles and policies, public S3 buckets or objects, disabled CloudTrail logging, security groups allowing unrestricted inbound access, unencrypted EBS volumes and S3 buckets, exposed EC2 instance metadata, and IAM users with long-lived access keys that are never rotated.

What is AWS IAM privilege escalation?

IAM privilege escalation refers to attack chains where a low-privilege AWS principal can use existing permissions to grant themselves additional permissions: effectively becoming an admin. Common paths include iam:PassRole with ec2:RunInstances, iam:CreateLoginProfile on existing admin users, and lambda:CreateFunction with iam:PassRole. These paths are often present in environments with broadly scoped IAM policies.

What is the CIS AWS Foundations Benchmark?

The CIS Foundations Benchmark for AWS is a set of prescriptive security configurations published by the Center for Internet Security. It covers IAM, logging, monitoring, networking, and storage configuration. The benchmark is used as a baseline for AWS security assessments and maps to compliance requirements in SOC 2, PCI DSS, and HIPAA.

How does AWS GuardDuty work?

AWS GuardDuty is a threat detection service that continuously monitors CloudTrail, VPC Flow Logs, and DNS logs for malicious activity. It uses machine learning, anomaly detection, and integrated threat intelligence to identify threats like crypto mining, unauthorized access, and compromised EC2 instances. GuardDuty findings should be integrated into your security operations workflow.

Is AWS responsible for cloud security?

AWS operates under the Shared Responsibility Model. AWS is responsible for security of the cloud: the underlying infrastructure, hardware, and global network. Customers are responsible for security in the cloud: the data they store, the applications they run, IAM configurations, network controls, and encryption. Most cloud breaches result from customer-side misconfigurations, not AWS infrastructure failures.

How long does an AWS security assessment take?

A focused AWS security assessment of a single-account environment typically takes one to two weeks. Multi-account AWS Organizations environments with complex architectures take two to four weeks. The assessment includes discovery, finding documentation, and a remediation roadmap.
