I need to write a query to check for events of a snapshot taken using programmatic access :
event where cloud.type = 'aws' AND operation = 'CreateInstanceSnapshot' AND json.rule = $.userIdentity.type = "Consolepassword"
Till now I have tried to do this, and I am pretty sure "json.rule = $.userIdentity.type = "Consolepassword" is 100% incorrect.
I need help on the second part to check if the user is using programmatic access or console access to take a snapshot.
Looking into CloudTrail's options for the type field, I don't see an option for "Consolepassword" :
All types though do not differentiate consoel vs. API operation, just where did it come from, i.e. other account, AD, IAM, assumed role etc.
I think using JSON rule for eventtype might be more beneficial. More info on AWS page, look for eventType:
AwsApiCall – An API was called.
AwsServiceEvent – The service generated an event related to your trail. For example, this can occur when another account made a call with a resource that you own.
AwsConsoleSignin – A user in your account (root, IAM, federated, SAML, or SwitchRole) signed in to the AWS Management Console.
So consider doing:
event where cloud.type = 'aws' AND operation = 'CreateInstanceSnapshot' AND json.rule = $.eventType = "AwsApiCall"
In addition, you can add a filter to include specific email addresses with MATCHES or excluding specific known users from the output.
Did that help?
Hi @SRohatyn ,
Thanks a lot for your valuable inputs and related reference links. I am able to get the result with little modification.
event where cloud.type = 'aws' AND operation = 'CreateSnapshot' AND json.rule != (( $.userAgent = 'signin.amazonaws.com' ) OR ($.userAgent = 'console.amazonaws.com' ))
This is giving me the desired results. A big thanks for your help.
