🚀 Why I Built This

I built this tool because I witnessed a real-world security gap that most organizations overlook: unused AWS access keys. During a recent cloud security assessment for a mid-sized company, I discovered that over 40% of their IAM access keys had never been used—or hadn't been used in months. Some dated back to former employees who had left the company years ago. These dormant keys represented a significant attack surface, yet there was no easy way to identify them at scale.

The trigger came when I tried to explain the findings to the client. I was manually pulling IAM user lists, checking each key's last-used date in the console, and trying to explain why a key that was "created but never used" was actually more dangerous than one that was used 6 months ago. The manual process was error-prone, time-consuming, and impossible to repeat for ongoing monitoring. The client needed something they could run weekly, produce audit-ready evidence for their SOC 2 audits, and integrate into their compliance workflow.

I designed this tool to solve that exact problem. It automates the entire IAM access key audit process, classifies risk based on industry-standard thresholds, maps findings directly to SOC 2 and NIST controls, and outputs evidence files that auditors love. I also added a mock mode so you can demonstrate the tool's capabilities without needing AWS credentials—perfect for portfolio presentations and technical interviews.

🎯 The Problem It Solves

Before (Manual Process)	After (This Tool)
Manually navigate AWS Console for each IAM user	One command scans all IAM users and keys
No standardized risk classification	5-tier risk classification (CRITICAL → COMPLIANT)
No compliance mapping	Auto-maps to SOC 2 CC6.1 and NIST IA-4
No audit evidence	Generates JSON + CSV reports instantly
Time-consuming (hours)	Fast execution (seconds)
Error-prone manual tracking	Consistent, repeatable results
No visual summary	Rich CLI table with color-coded risk levels

"The biggest security risk in cloud environments isn't sophisticated hackers—it's forgotten credentials. This tool makes forgotten credentials visible, actionable, and auditable."

🔧 How It Works

The tool follows a straightforward architecture: it connects to AWS IAM using boto3 (or uses mock data for testing), retrieves all IAM users and their access keys, calculates how long each key has been inactive, classifies the risk level based on predefined thresholds, maps findings to compliance controls, and outputs structured reports.

    style L fill:#ffcc00,color:#000
    style M fill:#ffff00,color:#000
    style N fill:#00ff00,color:#000

In plain English: The script asks AWS "Hey, give me all your IAM users and their access keys." For each key, it asks "When was this key last used?" It then compares that date to today to see how many days of inactivity have passed. Based on how many days have passed, it assigns a risk level—more inactive time means higher risk. Finally, it prints a nice color-coded table on your screen and saves two files: one for auditors (JSON) and one for spreadsheets (CSV).

🛡️ Risk Classification Engine

This tool uses a five-tier risk classification system based on industry best practices and compliance requirements. Each level corresponds to a specific inactivity timeframe and includes recommended remediation actions.

Risk Level	Inactivity Threshold	Remediation Action
CRITICAL	Key was NEVER used AND is older than 90 days	Deactivate immediately. Delete after 7 days.
HIGH	Last used more than 90 days ago	Deactivate immediately. Rotate and notify owner.
MEDIUM	Last used 45–90 days ago	Schedule rotation. Warn key owner.
LOW	Last used 30–45 days ago	Monitor usage. Recommend upcoming rotation.
COMPLIANT	Used within the last 30 days	No action required.

pie title Risk Distribution (Example Audit)
    "COMPLIANT" : 33
    "LOW" : 11
    "MEDIUM" : 22
    "HIGH" : 22
    "CRITICAL" : 11

🔒 Security First

I built this tool with security at the forefront. Here are the key security considerations:

Read-Only IAM Policy (Recommended)

For production use, create an IAM user with read-only permissions specifically for this audit:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "iam:ListUsers",
                "iam:ListAccessKeys",
                "iam:GetAccessKeyLastUsed"
            ],
            "Resource": "*"
        }
    ]
}

This policy only allows listing users, listing access keys, and checking last-used dates—no write or delete permissions.

Mock Mode for Safe Testing

The --mock flag lets you test the entire workflow without any AWS credentials. This is perfect for:

Portfolio demonstrations
Technical interviews
CI/CD pipeline testing
Learning the tool's behavior

No Secrets Stored

The tool never stores AWS secrets. It uses boto3's default credential chain (environment variables, config file, or IAM role). For the read-only policy above, you only need an Access Key ID and Secret Access Key with read permissions.

Report Sensitivity

Generated reports contain:

IAM usernames
Access key IDs (first 4 characters visible, rest masked in some outputs)
Risk classifications
Remediation recommendations

Recommendation: Add reports to .gitignore for production use:

reports/
*.json
*.csv

📋 Compliance Mapping

This tool maps security findings directly to two major compliance frameworks: SOC 2 and NIST SP 800-53.

What Are These Frameworks?

SOC 2 (Service Organization Control 2): A compliance framework that defines how organizations should manage customer data. It's designed for service organizations that store, process, or transmit customer data. SOC 2 has five "Trust Service Criteria": Security, Availability, Processing Integrity, Confidentiality, and Privacy. Auditors check that you have controls in place to protect data.

NIST SP 800-53: A publication by the National Institute of Standards and Technology that provides a catalog of security and privacy controls for federal information systems. Many private organizations adopt these controls as industry best practices. "IA-4" specifically covers identification and authentication management.

Control Mapping Table

Finding	SOC 2 Control	NIST Control	Description
Unused Access Keys	CC6.1	IA-4	CC6.1 requires logical access controls to protect against unauthorized disclosure. IA-4 requires proper management of identifiers (like access keys).
Inactive Keys	CC6.2	AC-2	CC6.2 covers access enforcement. AC-2 requires account management including removing access when no longer needed.
Key Rotation	CC6.1	IA-4	Both require periodic credential rotation to reduce risk from compromised keys.

💻 Tech Stack & Specs

Component	Technology	Purpose
Language	Python 3.10+	Core scripting
AWS SDK	boto3	AWS IAM API integration
CLI UI	rich	Color-coded table output

👤 About the Author

I'm a GRC (Governance, Risk, and Compliance) professional passionate about cloud security and regulatory compliance. I built this tool to demonstrate practical automation skills for IAM security monitoring—something I saw as a gap in many organizations' compliance programs.

I specialize in SOC 2 audits, NIST framework implementation, and cloud security assessments. This project represents my ability to bridge the gap between security concepts and technical implementation—translating compliance requirements into working code that produces audit-ready evidence.

I believe automation is the future of GRC work. Manual compliance checking doesn't scale, and auditors need reproducible, consistent evidence. This tool is one example of how I'm applying that philosophy.

Let's connect! I'm always open to discussing cloud security, compliance automation, or GRC career opportunities.
