Okta rdp

Okta rdp DEFAULT

Okta’s Advanced Server Access (ScaleFT) is a tool allowing organizations to secure access to SSH and RDP servers via a centralized authentication method. However, if you need to secure access to databases, Kubernetes clusters, the cloud CLIs, switches, routers, or internal web applications, there are other options to consider. This blog post looks at a few alternatives and discusses the pros and cons of each. For the impatient, I’ve put together a quick feature matrix that might answer your questions right away. For all the rest, read on.

Okta Advanced Server Access

Brief product summary

Okta’s Advanced Server Access provides privileged access management (PAM) for cloud-native infrastructure.  Okta ASA did not build this capability in-house; it came from an acquisition Okta made in July 2018 of a company called ScaleFT. ScaleFT’s original competition came from a company called Gravitational, and their product, Teleport. In general, it is an access and authentication proxy for RDP and SSH access.  It allows administrators to set up access for users (grouped into teams) to servers, and implements role-based access control (RBAC) to allow differing levels of access per team to different servers.  Individual server credentials are not available to users, reducing the administrative impact of rotating and removing credentials.

Use cases

  • Centralized access to SSH and RDP servers.

Pluses

  • SSH access available.
  • RDP access available.
  • Single sign-on (SSO) for SSH/RDP and your identities in Okta.
  • Authorized requests leverage single-use client certificate or web token scoped to the user and resource being accessed.

Minuses

  • Okta’s software must be running on every server it manages access to.
  • Complex setup: in addition to the ScaleFT software on each server, a ScaleFT Gateway and ScaleFT local client must also be built and maintained for each cluster.
  • CLI-only client scares off non-engineers.
  • User credentials are assigned ephemerally adding complexity to deployments and uptime.
  • Backend configuration required to export audit logs to any 3rd-party.
  • ScaleFT agent audit logs are only accessible through an early access enablement.
  • Audit logs only cover SSH.
  • No auditing for RDP.
  • Complex pricing model.
  • Pricing based per server, which gets extremely expensive in ephemeral environments or those with high-n servers.

strongDM

Brief product summary

strongDM is a control plane to manage and monitor access to databases, servers, and Kubernetes. Their zero trust model means instead of distributing access across a combination of VPN, individual database credentials, and SSH keys, strongDM unifies user management in your existing SSO (Google, Onelogin, Duo, Okta, etc...) and keeps the underlying credentials hidden. Neither credentials nor keys are accessible by end users. Because strongDM deconstructs every protocol, it also logs all database queries, complete SSH and RDP sessions, and kubectl activity.

Use cases

  • Faster on-boarding- no need to provision database credentials, ssh keys, VPN passwords for each new hire.
  • Secure off-boarding- suspend SSO access once to revoke all database, server access.
  • Automatically adopt security best practices- least privilege, ephemeral permissions, audit trail.
  • Comprehensive logs- log every permission change, database query, ssh & kubectl command.

Pluses

  • Easy deployment - self healing mesh network of proxies that auto-discovers available database, ssh nodes & Kubernetes clusters.
  • No change to workflow- use any SQL client, CLI, or desktop BI tool.
  • Standardize logs across any database type, Linux or Windows server, and Kubernetes.
  • Graphical client for Windows and MacOS.
  • See and replay all activity with session recordings.
  • Manage via a user-friendly web browser interface.
  • Simple, straightforward pricing.

Minuses

  • Requires continual access to strongDM API for access to managed resources.

Teleport (Community Edition or Enterprise)

Brief product summary

Gravitational Teleport provides privileged access management (PAM) for cloud-native infrastructure. Teleport is an access and authentication proxy for SSH and Kubernetes API access. It's meant as a replacement for sshd and it works with existing OpenSSH clients and servers as-is. It allows administrators to set up access for users and groups to groups of servers, called clusters, and implements role-based access control (RBAC) to allow differing levels of access to different clusters. Individual server credentials are not available to users, reducing the administrative impact of rotating and removing credentials.

The open source Community Edition of Teleport is the same as the Enterprise edition, with the following exceptions:

  • No RBAC
  • No SSO integration
  • No paid support available

Use cases

  • Centralized access to servers and Kubernetes.
  • Granting user SSH access to the same usernames across a cluster of servers.

Pluses

For the Enterprise Edition:

  • SSH access available via web UI on proxy server.
  • Single sign-on (SSO) for SSH/Kubernetes and your organization identities via Github Auth, OpenID Connect or SAML with endpoints like Okta or Active Directory.
  • Can use with an existing OpenSSH infrastructure.
  • Teleport uses SSH certificate-based access with automatic certificate expiration time.

For the Community Edition:

Minuses

For the Enterprise Edition:

  • Teleport software must be running on every server to be managed by Teleport access.
  • Complex setup: in addition to the Teleport software on each server, a Teleport Proxy and TeleportAuth server must also be built and maintained for each cluster.
  • CLI-only client scares off non-engineers.
  • User credentials are assigned across a full cluster rather than server-by-server.
  • Backend configuration required to store audit logs (AWS S3 / DynamoDB, required by teleport to store session logs).
  • Teleport agent audit logs are only accessible through the UI or backend storage.
  • Complex pricing model.

For the Community Edition:

  • Because it’s available for free, only community support is available.
  • The free version is missing important enterprise features (see above).
  • Only uses local users or Github for identity-based authentication.

Bastion Hosts

Brief product summary

A bastion, or jump, host is simply a Linux/UNIX server that mediates access to sensitive servers/database access by requiring the user to first log into the bastion host then ‘jump’ to additional resources in the network controlled by the bastion. Organizations simply need to set up an additional server that is both accessible from external sources and is able to connect to internal resources.

Use cases

  • Mediate access to protected resources on a restricted network segment.
  • Database clients and similar tools can work via bastion host by using port forwarding over the SSH connection.

Pluses

  • Free, or nearly so: the only requirement is the cost for the hardware (or virtual server) underlying the bastion host.
  • Straightforward access for users who are familiar with SSH.

Minuses

  • Because all access to protected resources requires first logging in via command line to the bastion host, the user must have an account on the bastion and a certain level of technical acumen, especially if employing port forwarding for database access.
  • The bastion host represents a single point of failure; if it is unavailable all resources behind it are inaccessible. Setting up multiple bastion hosts to mitigate against this possibility means another set of credentials to manage.
  • In the case of problems, support is limited to whatever support may be available for the underlying OS running on the bastion host.
  • Session logs and database/other protocol activity are not captured.

Alternatives to Twingate

Twingate started in 2019 in response to the growing challenges of managing access for a remote workforce. The product offers a zero-trust, cloud-based solution that aims to replace Virtual Private Networks (VPNs) by providing a secure, quick-to-implement solution for IT admins and everyday users. However, if you have a distributed workforce in need of access to databases, Kubernetes clusters, cloud CLIs, switches, routers, or internal web applications, there are other tools to consider. In this blog post, we’ll discuss the strengths and weaknesses of a few alternatives. But first, a side-by-side look at the features you may want to consider.

Install the Okta Credential Provider for Windows

Modify additional properties

In addition to the parameters you added in the previous step, you can modify the following properties to ensure MFA is always enforced.

PropertyDefinitionDefault ValueSuggested Value

This property provides a workaround when multiple credential providers are installed on a server. If true the Okta MFA Credential Provider is the only method for applying MFA to RDP connections and does not permit unauthenticated users to select which credential provider to use.

Setting FilterCredentialProvider to true and RdpOnly to false will cause the agent to prompt for MFA if required by the policy.

false-

Sets authentication flow behavior if network connectivity is lost. When true, a user attempting to authenticate across RDP is not challenged for MFA and is granted access based on password alone; when false, a user attempting to authenticate across RDP is not granted access because the credential provider cannot reach the Okta service.

InternetFailOpenOption governs proper access if the target machine does not have Internet access for MFA.

Set this property to true if Internet connectivity is a frequent issue.

false-

By default, the installed credential provider inserts Okta MFA between both an RDP and a local authentication event. Setting this property to true removes Okta MFA from local (interactive) logons.

Setting FilterCredentialProvider to true and RdpOnly to false will cause the agent to prompt for MFA if required by the policy.

false-
The number of seconds before timeout. To prevent the possibility that Windows might close the RDP session, this value must be smaller than the idle timeout set in Windows.6030
The timeout after which the RDP session is closed when an error message is displayed.3030
Enforce timeout for Windows 2012, 2016 or 2019. falsetrue
Validate the public key of the Okta server to which the agent is connecting.truetrue

If you upgraded from the version 1.1.4 to a later version, you must add this property.

Display link to reset Active Directory password.falsetrue

To modify these properties, edit the file that is typically located in the folder, or use the following power shell script.

$rdpAppConfig = Get-Content 'C:\Program Files\Okta\Okta Windows Credential Provider\config\rdp_app_config.json' -raw | ConvertFrom-Json $rdpAppConfig.RdpOnly =([System.Convert]::ToBoolean('true')) $rdpAppConfig | ConvertTo-Json | Set-Content 'C:\Program Files\Okta\Okta Windows Credential Provider\config\rdp_app_config.json'

You can run this script from the same location you ran the installation in step 2, above.

Info

Note

This script was tested with Powershell versions, 3, 4, and 5.
To determine Powershell version on your system, open Powershell as administrator and enter.
