Security policies for AWS Transfer Family servers - AWS Transfer Family

Security policies for AWS Transfer Family servers

Server security policies in AWS Transfer Family allow you to limit the set of cryptographic algorithms (message authentication codes (MACs), key exchanges (KEXs), and cipher suites) associated with your server. For a list of supported cryptographic algorithms, see Cryptographic algorithms. For a list of supported key algorithms for use with server host keys and service-managed user keys, see Supported algorithms for user and server keys.

Note

We strongly recommend updating your servers to our latest security policy. Our latest security policy is the default. Any customer who creates a Transfer Family server using CloudFormation and accepts the default security policy will be automatically assigned the latest policy. If you are concerned about client compatibility, please affirmatively state which security policy you wish to use when creating or updating a server rather than using the default policy, which is subject to change.

To change the security policy for a server, see Edit the security policy.

For more information on security in Transfer Family, see the blog post, How Transfer Family can help you build a secure, compliant managed file transfer solution.

Note

TransferSecurityPolicy-2024-01 is the default security policy attached to your server when creating a server using the console, API, or CLI.

Cryptographic algorithms

For host keys, we support the following algorithms:

  • rsa-sha2-256

  • rsa-sha2-512

  • ecdsa-sha2-nistp256

  • ecdsa-sha2-nistp384

  • ecdsa-sha2-nistp521

  • ssh-ed25519

Additionally, the following security policies allow ssh-rsa:

  • TransferSecurityPolicy-2018-11

  • TransferSecurityPolicy-2020-06

  • TransferSecurityPolicy-FIPS-2020-06

  • TransferSecurityPolicy-FIPS-2023-05

  • TransferSecurityPolicy-FIPS-2024-01

  • TransferSecurityPolicy-PQ-SSH-FIPS-Experimental-2023-04

Note

It is important to understand the distinction between the RSA key type—which is always ssh-rsa—and the RSA host key algorithm, which can be any of the supported algorithms.

The following is a list of supported cryptographic algorithms for each security policy.

Note

In the following table and policies, note the following use of algorithm types.

  • SFTP servers only use algorithms in the SshCiphers, SshKexs, and SshMacs sections.

  • FTPS servers only use algorithms in the TlsCiphers section.

  • FTP servers, since they don't use encryption, do not use any of these algorithms.

  • The FIPS-2024-05 and FIPS-2024-01 security policies are identical, except that FIPS-2024-05 doesn't support the ssh-rsa algorithm.

  • Transfer Family has introduced new restricted policies that closely parallel existing policies:

    • The TransferSecurityPolicy-Restricted-2018-11 and TransferSecurityPolicy-2018-11 security policies are identical, except that the restricted policy doesn't support the chacha20-poly1305@openssh.com cipher.

    • The TransferSecurityPolicy-Restricted-2020-06 and TransferSecurityPolicy-2020-06 security policies are identical, except that the restricted policy doesn't support the chacha20-poly1305@openssh.com cipher.

    *In the following table, the chacha20-poly1305@openssh.com cipher is included in the non-restricted policy only,

Note

The FIPS service endpoint and TransferSecurityPolicy-FIPS-2024-01 and TransferSecurityPolicy-FIPS-2024-05 security policies are only available in some AWS Regions. For more information, see AWS Transfer Family endpoints and quotas in the AWS General Reference.

The only difference between these two security policies is that TransferSecurityPolicy-FIPS-2024-01 supports the ssh-rsa algorithm, and TransferSecurityPolicy-FIPS-2024-05 doesn't.
