Q: Can I select which cryptographic algorithms can be used when my end users clients connect to my server endpoint? If a file validation check fails against preconfigured validation steps, you can use the exception handler to invoke your monitoring system or team members via Amazon SNS topic. Managed File Transfer Process Flow. Examples of commonly used SFTP/FTPS/FTP clients include WinSCP, FileZilla, CyberDuck, lftp, and OpenSSH clients. Q: Can I enable multiple protocols on the same endpoint? Deleting or archiving the file by copying it to another S3 bucket or storing it with a different S3 prefix. Refer to the documentation on managing host keys for your SFTP-enabled server. However, only one host key per key type can be used by your end users clients to verify the authenticity of your SFTP server in a single session. Why should I use the Custom authentication mode? You can enable fixed IPs for your server endpoint by selecting the VPC hosted endpoint for your server and choosing the internet-facing option. how the AWS Transfer Family uses Amazon Route 53 for custom domain names, creating your server endpoint inside your VPC, Creating your server endpoint inside your VPC, Refer to this blog post on using VPC hosted endpoints in shared VPC environments with AWS Transfer Family, managing host keys for your SFTP-enabled server, Enabling Password Authentication using Secrets Manager. This could be a custom identity provider, AWS Directory Service, or service managed. Q: Iam using AWS Step Functions to orchestrate my file-processing steps. The new managed workflows feature within AWS Transfer Family allows you to define a lightweight workflow that is invoked in response to file uploads. In this blog, I show you how to architect common MFT scenarios using the new Transfer Family managed workflows feature. For more information, refer to managed workflows documentation. A: Yes.

A: When you create your server, you select a directory in AWS Managed Microsoft AD, your on-premises environment, or self-managed AD in Amazon EC2 as your identity provider. AWS Transfer Familyprovides a fully managed service, reducing your operational costs to run file transfer services. Use VPC hosted endpoints to assign static IP addresses for your endpoint. The internal application that processes the file could be an in-house Java application, an Enterprise Resourcing Planning system that processes payments, telecommunication billing system that consumes call data, or even financial regulatory organization that scans daily share trading data for anomalies. This includes the operations you want to enable on their client and which Amazon S3 buckets they have access to whether its the entire bucket or portions of it. This results in the file being stored in the underlying Upload S3 bucket. If traffic needs to traverse the public network, secure protocols such as SFTP or FTPS should be used. Additionally, if you want to share the same credentials for SFTP and FTPS, you can set up and use a single identity provider for authenticating clients connecting over either protocol.

A: There are two aspects to messages transmission one from the sender and from the receiver. Q: How do I know when my trading partners certificates are expiring? Q: Can I rotate my SFTP server host keys to ensure secure connections? Non-repudiation in AS2 is achieved using Message Disposition Notifications (MDN). This will notify the service to send the message to your trading partners endpoint. You can also display customized Message of The Day (MOTD) to users who have successfully authenticated. How do AWS Transfer Family managed workflows differ from my current AWS Step Functions set up? At this point you are ready to exchange messages with your trading partners AS2 server. Q: Which compliance programs does AWS Transfer Family support? A:Yes, you can provide the same user access over multiple protocols, as long as the credentials specific to the protocol have been set up in your identity provider. File-based transfers are one of the most prevalent mechanisms for organizations to exchange data over various interfaces with their partners and consumers.

A: Yes, once you receive an MDN from your trading partner, the service validates the MDN using your certificate and stores the message in your Amazon S3 bucket. Route 53 resolves the domain name and provides the URL of the AWS Transfer Family endpoint. You have three options to restrict incoming traffic by users source IP address. AWS Transfer Family | Managed File Transfer | Amazon When an MDN is requested in a transaction, it ensures that the sender sent the message, the receiver successfully received it, and the message sent by the sender was the same message received by the receiver. Simply configure the server and user with the appropriate permissions to the EFS file system to access the file system across all operating systems. Financial, healthcare, retail and other companies exchange many different types of data. AWS Transfer Family integration with Amazon S3 can be used for storing file data.

If you already have a domain name, you can use Amazon Route 53 or any DNS service to route your users traffic from your registered domain to the server endpoint in AWS. Heres how it works: Figure 2. There are three fundamental drivers of cost with AWS: compute, storage, and outbound data transfer. You can use a pre-built, fully managed workflow step for PGP decryption of files. The first step is to copy a file to a different Amazon S3 location, and the second step to delete the originally uploaded file. This managed file transfer solution provides features to support data transformation, inbound, and outbound file transfers over FTP protocols. Q: Can I isolate each of my trading partners to use different inbound and outbound locations for messages? Similarly, you can also enable additional protocol support to existing AWS Transfer Family endpoints, as long as the the endpoint configuration meets the requirements for all the protocols you intend to use. Q: Can I use S3 Access Points with AWS Transfer Family to simplify user access to shared dataset? AWS Transfer Family is a secure transfer service that enables you to transfer les into and out of AWS storage services. You are also billed based on the amount of data uploaded and downloaded over SFTP, FTPS, or FTP, number of messages exchanged over AS2, and the amount of data processed using Decrypt workflow step.
