I got 4 aws accounts, and i want to centralise all my logs into a single accounts for security purposes.
Meaning collect cloudwatch logs from account prod, dev and perf into an account called logs. Ideally they would end up in cloudwatch in the accounts logs, so i can process them easily with ELK.
I read about it here:
http://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CrossAccountSubscriptions.html
But i can't find a tutorial on how to set up simply the whole stack.
Any suggestions would be appreciated.
The only thing different about using CloudWatch Logs in another account is the credentials you'll need to use.
I would do it like this; in your logs account, create 3 IAM users:
prod
dev
perf
Give each of the users the necessary IAM permissions to write logs to CloudWatch logs. Also, create a set of AWS credentials for the 3 users which you will use to authenticate with.
Then in your application, depending on what stack your in, configure your code to use the relevant credentials (i.e. Dev, Prod) to write to CloudWatch logs. The only difference should be wherever in your code you create the CloudWatch logs client. You should pass the client the credentials for the relevant IAM user from your "Logs" account.
EDIT:
If you're using the CloudWatch Logs client, the idea is the same. You create the users and instead just give the client the relevant AWS credentials. You specify the creds for the user from your logs account in the /etc/awslogs/awslogs.conf. The credentials you use is what will send your logs to CloudWatch in the other account. The process you need to follow is basically documented in the AWS docs

I turn on Audit Mode for AWS Cognito to enable Advanced Security Features, as stated here AWS docs:
After that, under User Pools-Users and Groups-User section, there are the Last 100 Authentication Events for each user
I want to re-record this information to a specific log group: auth-audit-log-group and log stream: user-{userId} in CloudWatch Logs. Reason: CloudWatch allows query based on timestamp. What is the best way to do that?
Pr: I look at postAuthentication and postConfirmation triggers but they cannot capture failed sign-up and sign-in.
I'm trying to add programmatically a "working" AWS account via API.
Actually I'm performing this operations:
Authentication
CreateUser (login)
CreateLoginProfile (password)
When I go on "AWS" console I get an error an if I look to the Accounts linked to the Organization I can't find my new account.
But if I go on https://console.aws.amazon.com/iam/home#/home the user is there.
Do I'm missing something? Is there any difference between USER and ACCOUNT?
Of course USER and ACCOUNT are different. An account contains users and other resources (S3 bucket, EC2 instance).
If you want to create new AWS account, you need to use Organizations API.
See:
create-account in the AWS CLI
CreateAccount documentation
Trying to put together an Azure ARM integration, where my code uses the Azure API to retrieve the full list of VMs in the entire subscription.
Went successfully through all the (many!) steps here to get an API user ready with all relevant IDs needed for authentication.
Using the same set of instructions, we were also able to grant this user the Reader role, for listing VMs in specific groups (we did this through the Azure UI). However, we have been unsuccessful in implementing the instructions here for setting up Reader role for this user to the entire subscription (through the CLI).
Running this:
azure role assignment create --objectId app-oid --roleName Reader --scope /subscriptions/subscription-id
Or this:
azure role assignment create --objectId app-oid --roleName Reader --subscription subscription-id --scope /subscriptions/subscription-id
Yields this:
Principals of type Application cannot validly be used in role assignments.
So currently we have no way of programmatically browsing the full set of VMs without adding a specific authorization for each Resource Group.
Does anybody know of a way that actually works to assign this permission at the subscription level?
Found the answer in the comment area of the link in the question body:
In the new portal, edit the subscription and add the role, just like you would do with a resource group. Still curious as to why the CLI doesn't support this.
The steps to use the Azure CLI to create and authorize a service principal are documents here: https://azure.microsoft.com/en-us/documentation/articles/resource-group-authenticate-service-principal-cli/
Instead of using --objectId app-oid try using -ServicePrincipalName <appId>
https://github.com/Azure/azure-powershell/issues/4776
Had the same error for role assignment with terraform
Principals of type Application cannot validly be used in role assignments.
But as described here, using the Object Id that is displayed on the overview page of the app registration in the Azure portal resulting the above error.
The solution is to get the Object Id from azure cli:
az ad sp show --id [Application (client) Id] -o json | grep objectId
# and then using this objectId assign your role
az role assignment create --role contributor —-assignee-object-id [object id] —-resource-group [MyResourceGroup]
I'm going to setup this Example for Amazon Cognito Sync demo, using Eclipse + ADK + AWS libs V2.9.
I created an identity pool in the Cognito Console, so I got the Identity Pool ID which is used in CognitoSyncClientManager.java at:
private static final String IDENTITY_POOL_ID = "us-east-1:1a23b013-1abc-123-b123-123abc1fe5";
private static final Regions REGION = Regions.US_EAST_1;**
(perhaps not all regions seem to run in test mode)
I registered my (developing-)app in the Seller Central with Eclipse Help>Android>Bild>MD5 fingerprint and the package-name from AndroidManifest.xml, so got my api_key.txt Value.
From the AWS doku I got my Provider URL (code as sample), which is used in DeveloperAuthenticationProvider.java at:
private static final String developerProvider = "cognito-sync.us-east-1.amazonaws.com";
private static final String cognitoSampleDeveloperAuthenticationAppEndpoint = "arn:aws:iam::123456789123:role/Cognito_TestMyAppAuth_DefaultRole"
private static final String cognitoSampleDeveloperAuthenticationAppName = "Cognito sync demo";
After creating some Users which are attached to groups with permissions to IAM full access and (auto)generated roles for unautherized and autherized Roles, my app is running in this way:
Login with Amazon - is running, but where will their datasets be created and is it possible I see them in the AWS Console?
Simple Browse your data (without login) - is running, unauthenticated users and their datasets appear/are counted in the Identity console
Developer Authentication fails with Username or password do not match - combined with an "Unable to reach resource..." in the LogCat.
Now I think, the last missing thing in this game is the parameter cognitoSampleDeveloperAuthenticationAppEndpoint=...
Where can I find it and what else could I have missed to setup for a full running Example?
Thanks for using Cognito demo. Answers to your questions
Yes, you can see the datasets in the AWS console. Navigate to Cognito inside the AWS Console and go to your identity pool. On the left hand side menu go to identity browser and you will see the list of identities or you can search for an identity. Click on the identity and you can see the datasets owned by that identity.
Developer Authentication is a feature which helps to integrate your authentication system with Cognito. For this you should have a backend server serving user's authentication requests, and once you authenticate users you can request OpenId Connect tokens for them from Cognito using the GetOpenIdTokenForDeveloperIdentity API call. The developer provider name is the one which you setup for your identity pool in the AWS Cognito console. For using the sample you can setup a sample server application by following this blog and the readme file of the the server side application.
P.S.: Please avoid sharing your identity pool id.
Thanks,

For example, I have a website with User A and B.
Both of them can login to my website using my own login system.
How do I make certain files from S3 accessible only to User A once he login to my website?
Note: I saw "Permission" in AWS Management Console with "Authenticated Users" option but it seems that it's meant for other S3 users only, is it something I can use to achieve my goal?
You need to use Amazon IAM - you can define what part of any S3 bucket A can see, as well as B and each will not have access to do 'anything'. In general you should never use the account ID and secret for anything, always make an IAM user have just whats needed to run your stuff. The admin user likely does not need EC2 or SQS, or SimpleDB, etc.
Federated access is great for allowing arbitrary users to sign into your website and only be granted access for say 12 hours. They get special AWSIDs for that access that will work only on the section of S3 you let them look at.
