Why should you care?

AwsVerse fraud alerts notify ops email, PagerDuty webhook, and audit SQS in one publish.

See it live — copy this example

Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).

aws sns publish \
  --topic-arn arn:aws:sns:ap-south-1:123456789012:awsverse-fraud-alerts \
  --message '{"alertId":"F-9921","severity":"high","accountId":"ACC-441"}' \
  --message-attributes '{"severity":{"DataType":"String","StringValue":"high"}}'

What happened?

• Publishes JSON to a topic; all subscribers receive filtered copies.
• Use message attributes for subscription filter policies.

Practice next

1. Create topic awsverse-fraud-alerts.
2. Subscribe email and SQS queue.
3. Publish test message; confirm both receive.
4. Add subscription filter on severity=high only.
5. Enable SNS SSE with KMS key.

Remember

SNS = pub/sub fan-out. Filter policies reduce noise. Pair with SQS for buffering.
