If GetSessionToken is called using AWS account root user credentials, the temporary credentials have root user permissions. For information about the parameters that are common to all actions, see Common Parameters. The duration, in seconds, that the credentials should remain valid. Acceptable durations for IAM user sessions range from seconds 15 minutes toseconds 36 hourswith 43, seconds 12 hours as the default. Sessions for AWS account owners are restricted to a maximum of 3, seconds one hour.

If the duration is longer than one hour, the session for AWS account owners defaults to one hour. The regex used to validate this parameter is a string of characters consisting of upper- and lower-case alphanumeric characters with no spaces.

If MFA authentication is required, the user must provide a code when requesting a set of temporary security credentials. A user who fails to provide the code receives an "access denied" response when requesting resources that require MFA authentication.

The format for this parameter, as described by its regex pattern, is a sequence of six numeric digits. The temporary security credentials, which include an access key ID, a secret access key, and a security or session token. We strongly recommend that you make no assumptions about the maximum size.

Establish and enforce Network Access Protection NAP client health policies that determine whether devices are granted unrestricted or restricted access to network resources.

Provide a way to enforce authentication and authorization for access to For more information, see Network Policy Server. To enhance security and provide a high level of compliance, organizations can integrate NPS with Azure Multi-Factor Authentication to ensure that users use two-step verification to connect to the virtual port on the VPN server.

For users to be granted access, they must provide their username and password combination and other information that they control. This information must be trusted and not easily duplicated. It can include a cell phone number, a landline number, or an application on a mobile device.

Prior to the availability of the NPS extension for Azure, customers who wanted to implement two-step verification for integrated NPS and MFA environments had to configure and maintain a separate MFA server in an on-premises environment.

When users connect to a virtual port on a VPN server, they must first authenticate by using a variety of protocols. The protocols allow the use of a combination of user name and password and certificate-based authentication methods. In addition to authenticating and verifying their identity, users must have the appropriate dial-in permissions.

In simple implementations, dial-in permissions that allow access are set directly on the Active Directory user objects.

In simple implementations, each VPN server grants or denies access based on policies that are defined on each local VPN server. Before you begin, you must have the following prerequisites in place:. If you do not have a working VPN infrastructure in place, you can quickly create one by following the guidance in numerous VPN setup tutorials that you can find on the Microsoft and third-party sites.

This article assumes that you have installed the Network Policy and Access Services role on a member server or domain controller in your environment. NAP is deprecated in Windows Server For testing purposes, you can use a trial subscription. All the steps in this guide were performed with Windows Server If the Microsoft Azure Active Directory PowerShell Module is not already present, it is installed with a configuration script that you run as part of the setup process.

There is no need to install the module ahead of time if it is not already installed. Instructions for enabling users for MFA are provided below.

In the Time-out seconds box, enter a value of The timeout value is necessary to allow enough time to complete the second authentication factor.Okta is commonly used to perform user federation for online applications and this includes AWS.

This somewhat defeats the purpose of utilizing the federated users with Okta since you still need to create and manage users and their keys.

This will initiate a configuration wizard that will prompt you for the details needed to configure the tool. The —configure flag can also be used to update the configuration.

Running the config wizard looks like the following, with the defaults or current config if one exists located in the brackets. Access to this link is only available by an Okta user with admin rights. If you are not an admin you will need to have an admin provide you the URL. This overwrites the existing credentials in the default profile. Note: These are temporary credentials that have expired so they are no longer valid by the time this post has been published. Also as stated in the output, the credentials are only valid for 60 minutes.

This means that after 60 minutes the temporary credentials will expire and new ones will need to be generated. By default Okta sessions timeout after 2 hours of inactivity.

The following MFA login types are supported:. Awesome tool! Any chance you could add support for the yubikey mfa method? I might even have an extra yubikey you can have if needed for testing!

Returns a set of temporary security credentials that you can use to access AWS resources that you might not normally have access to. These temporary credentials consist of an access key ID, a secret access key, and a security token.

Typically, you use AssumeRole within your account or for cross-account access. For cross-account access, imagine that you own multiple accounts and need to access resources in each account. You could create long-term credentials in each account to access those resources. However, managing all those credentials and remembering which one can access which account can be time consuming.

Instead, you can create one set of long-term credentials in one account. Then use temporary security credentials to access all the other accounts by assuming roles in those accounts. By default, the temporary security credentials created by AssumeRole last for one hour. However, you can use the optional DurationSeconds parameter to specify the duration of your session. You can provide a value from seconds 15 minutes up to the maximum session duration setting for the role. This setting can have a value from 1 hour to 12 hours.

However the limit does not apply when you use those operations to create a console URL. Optional You can pass inline or managed session policies to this operation. You can pass a single JSON policy document to use as an inline session policy.

You can also specify up to 10 managed policies to use as managed session policies. The plain text that you use for both inline and managed session policies can't exceed 2, characters.

Passing policies to this operation returns new temporary credentials. The resulting session's permissions are the intersection of the role's identity-based policy and the session policies. You can use the role's temporary credentials in subsequent AWS API calls to access resources in the account that owns the role. You cannot use session policies to grant more permissions than those allowed by the identity-based policy of the role that is being assumed.

To assume a role from a different account, your AWS account must be trusted by the role. The trust relationship is defined in the role's trust policy when the role is created. That trust policy states which accounts are allowed to delegate that access to users in the account. A user who wants to access a role in a different account must also have permissions that are delegated from the user account administrator.

The administrator must attach a policy that allows the user to call AssumeRole for the ARN of the role in the other account. If the user is in the same account as the role, then you can do either of the following:. In this case, the trust policy acts as an IAM resource-based policy.Did you find this page useful?
