Set a security level for your gateway - AWS Storage Gateway

Set a security level for your gateway

By using a S3 File Gateway, you can specify a security level for your gateway. By specifying this security level, you can set whether your gateway should require Server Message Block (SMB) signing or SMB encryption, or whether you want to allow SMB version 1.

To configure security level

  1. Open the Storage Gateway console at https://console.aws.amazon.com/storagegateway/home.

  2. Choose Gateways, then choose the gateway for which you want to edit SMB settings.

  3. From the Actions dropdown menu, choose Edit SMB settings, then choose SMB security settings.

  4. For Security level, choose one of the following:

    Note

    For information about configuring this setting using the AWS API, see UpdateSMBSecurityStrategy in the AWS Storage Gateway API Reference.

    A higher security strategy level can affect performance of the gateway.

    • Mandatory encryption – If you choose this option, S3 File Gateway only allows connections from SMBv3 clients that use 256-bit AES encryption algorithms. 128-bit algorithms are not allowed. This option is recommended for environments that handle sensitive data. It works with all current SMB clients on Microsoft Windows.

    • Enforce encryption – If you choose this option, S3 File Gateway only allows connections from SMBv3 clients that have encryption turned on. Both 256-bit and 128-bit algorithms are allowed. This option is recommended for environments that handle sensitive data. It works with all current SMB clients on Microsoft Windows.

    • Enforce signing – If you choose this option, S3 File Gateway only allows connections from SMBv2 or SMBv3 clients that have signing turned on. This option works with all current SMB clients on Microsoft Windows.

    • Client negotiated – If you choose this option, requests are established based on what is negotiated by the client. This option is recommended when you want to maximize compatibility across different clients in your environment.

    Note

    For gateways activated before June 20, 2019, the default security level is Client negotiated.

    For gateways activated on June 20, 2019 and later, the default security level is Enforce encryption.
