Introduction:
AWS has introduced a significant update to its Security Agent service, now allowing users to export comprehensive penetration testing reports in PDF format. This enhancement transforms Security Agent from a simple feedback mechanism into a powerful, documentation-ready tool for security validation, moving it closer to a fully-fledged pentesting solution. Currently available in a free preview, this feature is poised to change how cloud engineers and security professionals approach infrastructure validation, provided it remains confined to non-production environments.
Learning Objectives:
- Understand the new PDF export functionality within AWS Security Agent and its implications for security reporting.
- Learn how to enable and execute a security scan using AWS Security Agent on a test environment.
- Explore the step-by-step process to generate, export, and interpret the new pentest report.
You Should Know:
1. Enabling and Running AWS Security Agent Scans
The AWS Security Agent, currently in preview, is designed to provide security feedback by simulating attacker behavior to identify misconfigurations and vulnerabilities. The newly added PDF export feature allows users to formalize these findings into a professional pentest report.
To begin, ensure you have an AWS account and have enabled the Security Agent preview for your desired region (commonly us-east-1). Access it via the AWS Management Console under “Security, Identity, & Compliance” or by navigating directly to the Security Agent service.
Step‑by‑step guide explaining what this does and how to use it:
1. Enable the Agent: Navigate to the Security Agent console and click “Get started.” Select a non-production AWS account or a dedicated test environment.
2. Configure a Scan: Define the scope of your assessment. This typically involves selecting specific AWS resources (EC2 instances, S3 buckets, IAM roles) or tagging them for discovery.
3. Initiate the Scan: Click “Start assessment.” The agent will begin analyzing the environment for common attack paths, misconfigurations, and exposed services.
4. Monitor Progress: The scan can take anywhere from 15 minutes to a few hours depending on the size of your environment.

2. Exporting the Pentest Report (PDF)
Once the assessment completes, the “Reports” section within the Security Agent dashboard will become populated. Here, you can access the newly formatted PDF export. Unlike raw logs or JSON outputs, this PDF is structured to be client-facing, offering clear narratives of risks.
Step‑by‑step guide explaining what this does and how to use it:
1. Navigate to Reports: After the scan finishes, go to the “Reports” tab in the left-hand navigation pane.
2. Select the Assessment: Click on the specific assessment you just ran.
3. Export Options: Look for the “Export” button. You will now see an option for “Download PDF Report.” Previously, this might have been limited to CSV or JSON.
4. Review the PDF: Open the downloaded PDF. The report is designed to be minimally cluttered, focusing on:
– Executive Summary: A high-level overview of risk posture.
– Findings: Detailed technical vulnerabilities, often categorized by severity (Critical, High, Medium, Low).
– Remediation Steps: Clear instructions on how to mitigate each identified issue.

3. Understanding the Report Structure and Remediation
The core value of the PDF report lies in its actionable format. For a security professional, this output can be directly attached to a ticket in a project management tool or handed to a development team without extensive rewriting. It bridges the gap between detection and remediation.
To maximize this, combine the output with Infrastructure as Code (IaC) validation. For example, if the report finds an S3 bucket with public read access, you can enforce a policy using the AWS CLI:
Check bucket ACLs aws s3api get-bucket-acl --bucket your-bucket-name Remediate by blocking public access (using CLI) aws s3api put-public-access-block --bucket your-bucket-name --public-access-block-configuration "BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true"
If the report identifies an overly permissive IAM role, you can use the AWS CLI to attach a stricter policy:
Detach a wide policy aws iam detach-role-policy --role-name vulnerable-role --policy-arn arn:aws:iam::aws:policy/AdministratorAccess Attach a least-privilege policy aws iam attach-role-policy --role-name vulnerable-role --policy-arn arn:aws:iam::aws:policy/ReadOnlyAccess

4. Integrating Security Agent into CI/CD Pipelines
For DevSecOps practitioners, the ability to automate the generation of these reports is crucial. While the console export is useful for ad-hoc reviews, leveraging the AWS CLI or SDKs to programmatically trigger scans and retrieve artifacts is the goal. This allows for security validation to occur automatically before a production deployment.
Step‑by‑step guide explaining what this does and how to use it:
1. Install AWS CLI: Ensure you have the latest version of the AWS CLI installed. Verify with:
aws --version
2. Trigger a Scan via CLI: Use the `start-assessment` command. Replace the ARN with your target environment ARN.
aws securityagent start-assessment --target-arn arn:aws:your-resource-arn
3. Wait for Completion: Use `describe-assessment` to poll the status.
aws securityagent describe-assessment --assessment-id <your-id>
4. Download Report Programmatically: Once complete, you can script the download of the PDF. This allows you to store reports in S3 for compliance auditing or attach them to pull requests.

5. Complementary Security Hardening
AWS Security Agent is a fantastic tool for identifying issues, but it should be part of a larger cloud hardening strategy. The reports often highlight gaps that can be closed with proper configuration management. For Windows-based EC2 instances, this might involve configuring the Windows Firewall via PowerShell.
Example of hardening Windows instances based on common findings:
Block SMB ports if not needed (common attack vector) New-NetFirewallRule -DisplayName "Block SMB 445" -Direction Inbound -LocalPort 445 -Protocol TCP -Action Block Enable Windows Defender real-time monitoring Set-MpPreference -DisableRealtimeMonitoring $false
For Linux-based instances, consider implementing automated patching and SSH hardening:
Disable root SSH login sudo sed -i 's/PermitRootLogin yes/PermitRootLogin no/g' /etc/ssh/sshd_config sudo systemctl restart sshd Set up automatic security updates sudo apt-get install unattended-upgrades sudo dpkg-reconfigure --priority=low unattended-upgrades

6. API Security Implications
The new report feature also highlights a growing trend: the integration of “Agentic AI” into security tools, as mentioned in the original post. AWS is moving towards automated agents that not only find flaws but can potentially fix them. The PDF export is a stepping stone, providing clear evidence of what these AI agents are discovering.
When reviewing the report, pay close attention to API security findings. Misconfigured API gateways, exposed Lambda functions, and insecure API keys are common in modern cloud setups. Use the AWS API Gateway CLI to audit these areas:
List all API Gateway stages to check for logging and caching issues aws apigateway get-stages --rest-api-id <api-id> Check for WAF associations (Web Application Firewall) aws wafv2 list-web-acls --scope REGIONAL

7. Vulnerability Exploitation and Mitigation
While the Security Agent is a defensive tool, understanding how the vulnerabilities it finds are exploited is key to proper mitigation. The report typically maps findings to the MITRE ATT&CK framework.
For example, if the report finds “Unrestricted Security Group Rules” (e.g., 0.0.0.0/0 on port 22), the exploit path is clear: external brute-force attacks. The mitigation involves restricting access to specific IP ranges. You can automate this using AWS CLI to update security groups:
Remove an overly permissive inbound rule aws ec2 revoke-security-group-ingress --group-id sg-12345678 --protocol tcp --port 22 --cidr 0.0.0.0/0 Add a restricted rule aws ec2 authorize-security-group-ingress --group-id sg-12345678 --protocol tcp --port 22 --cidr 203.0.113.0/24
What Undercode Say:
- The introduction of PDF pentest reports in AWS Security Agent marks a significant maturation of the service, making it a viable alternative for preliminary compliance and security assessments.
- Organizations must strictly adhere to the “non-production only” warning; using this tool against live production environments risks performance degradation and potential data exposure.
- The trend towards “agentic AI” in cloud security is accelerating, shifting the paradigm from manual review to automated discovery and reporting.
Prediction:
The integration of automated reporting with AI-driven analysis will soon standardize cloud security postures, reducing the gap between development and security operations. Within the next year, expect Security Agent to evolve from a preview tool into a paid, essential component of AWS’s native security suite, potentially integrating with Amazon Inspector and AWS Shield to provide a unified, continuous validation service.
