Create a report of Network Access Analyzer findings for inbound internet access in multiple AWS accounts 1

This template is used to create a Network Access Analyzer (NAA) report. The intent is to scan and report on any paths on which incoming internet traffic is being received by your AWS environment. This is useful when you have more than one AWS account and you would rather that none of them accidentally exposed.

The template uses AWS services like:

• IAM Roles – for restricted and secure access.

• EC2 Instances – to execute analysis or monitoring software.

• Amazon EventBridge – to notify when something out of the ordinary is discovered.

• Amazon SNS – to send automatic notifications when something goes wrong.

It gives you an immediate visibility of your AWS environment's vulnerability and allows you to repair issues before they become critical.

Why This Template is a game changer ?

Cloud security is likely to be complex. There are numerous policies, rules, and resources distributed across accounts and regions. This tends to make it difficult to get a good sense of what the internet is exposed to.
This template helps by:

• Automatically finding risks – No necessity to review every route or firewall manually.

• Sending alerts in real time – You know the moment something risky shows up.

• Logging and reporting storage – Useful for audits and tracking what occurred.

• Working across accounts – You have one location where you can see all your AWS environments.

If you must secure your cloud setup, this template is faster, less prone to errors, and provides peace of mind.

Who can use this Template and When? 

This template can be used by any person who has the responsibility of securing AWS environments, including:

• Cloud security groups

• DevOps engineers

• IT administrators

• Compliance teams

It's most helpful when: 

• You're dealing with several AWS accounts.

• You have just refreshed your VPCs, security groups, and firewall rules.

• You have to be ready for a security audit.

• You wish to automate frequent checking for internet exposure.

Main Components of the Template :

This template combines several AWS services that collaborate to detect, monitor, and report on internet access coming in:

• AWS Security – Scans your network for publicly accessible entry points.

• IAM Roles – Specifies who is allowed to do what, which avoids unwanted modifications.

• EventBridge Rule – Tracks dangerous changes or trends and triggers alerts.

• SNS Topic – Alerts your phone or email so that you can reply promptly.

• EC2 Instance – Executes any scanning or monitoring tools required for analysis.

• S3 Bucket – Safeguards reports, logs, and history data.

• Private Subnet – Isolated internal resources from public access.

• Public Subnet – Controls internet-facing resources such as websites or APIs.

• Management IAM Role – Used by administrators to control the entire setup.

• Workload IAM Role – Used to assign applications such that they receive only the access they require.

• AWS Logs – Tracks logs of all network activities.

• AWS Networking – Supports traffic routing and VPC configuration.

• Security Event Monitoring – Monitors threats or suspicious activity.

• Access Policy Rule – Specifies what can be permitted and what should be denied.

• Audit Trail Repository – Holds all audit logs, reviews, and compliance audits.

All of these factors put together provide you with an overall view of your network security status.
