Set Up Privileged Session Management
Privileged Session Manager (PSM) is an application cluster used to access, record, and monitor privileged sessions. It can be hosted as a Docker Swarm on local or cloud service locations. It launches when users with Login Session Access to a managed computer check out the credentials for that computer. You can configure PSM to record session activity, allowing Access Managers and other administrators to view what users do on the computer during a session.
This topic walks you through the process of setting up PSM. To completely set up PSM, you need to do the following:
Install Docker and Docker-Compose on a Linux server. The Linux server is the PSM server.
Create an OAuth application for PSM in EmpowerID.
Configure EmpowerID System Settings for PSM.
Generate a X509 certificate for the PSM OAuth application and upload it to the local machine and EmpowerID certificate stores.
Create a service account (EmpowerID Person) for PSM and map the certificate to that service account.
Use OpenSSL to extract the private and public key from the certificate.
Create Docker secrets on the PSM server.
Copy the psm.yml file you receive from EmpowerID to the root directory of the Linux server.
Initiate Docker swarm mode on the Linux server.
Pull the PSM Docker images from Dockerhub.
Deploy the stack.
To comply with European Union GDPR (General Data Protection Regulation) that was implemented on May 25, 2018, you must do one of two things:
Turn off live monitoring and session recording. (See Creating Privileged Session Policies.)
Clearly alert the user that their session will be recorded, how it will be recorded, and that they can opt out of such monitoring by not continuing to the session.
To set up PSM, you must have a good understanding of containerization technologies and their advantages, the Docker Command Line and Docker Container Management System. If you are not familiar with Docker, the following resources may be helpful:
What is Docker?
What is Docker Hub?
What is Docker swarm?
In addition to understanding Docker, you must have access to the below PSM Docker images:
empowerid/psm_app:0.1.0
empowerid/psm_daemon:0.1.0
empowerid/psm_uploader:0.1.0
OpenSSL
OpenSSL is needed to extract the KEY from the certificate you will generate and map the Service Account used for PSM. If you do not have OpenSSL installed, you can do so by following the instructions provided here:
PSM Server Installation Instructions
PSM Server requires a Linux instance (Amazon AMI/Ubuntu preferred). Follow the below instructions to install Docker and Docker-Compose on the server.
Ubuntu — Run the following commands one after the other:
sudo apt-get remove docker docker-engine docker.io containerd runc curl =fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-get add - sudo apt-get update sudo apt-get install -y docker-ce sudo systemctl status docker
Amazon AMI — If you are running Linux on Amazon AMI, please follow the instructions provided by Amazon at the following link: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/docker-basics.html#install_docker
EmpowerID Server Setup Instructions
In order to implement PSM for your environment, there are a number of tasks you must complete on your EmpowerID server. These include:
Creating an OAuth Application for PSM
Configuring EmpowerID System Settings for PSM
Generating a self-signed X509 certificate for PSM
Creating a PSM service account (EmpowerID Person)
Mapping the PSM certificate to PSM service account
Step 1 – Create an OAuth Application for PSM
On the navbar, expand Apps and Authentication and click Applications.
From the Actions pane, click Create OAuth Application.
This opens the OAuth Provider Application Details form.In the OAuth Application Details section of the form, do the following:
Fill in the Name, Display Name and Description fields with values that reflect the purpose of the application.
Select Web Application from the Application Type drop-down.
Search for and select an owner for the application from the Application Owner drop-down. By default, the creator of the application is selected as the owner.
In the JWT Details section of the form, do the following:
Leave the Issuer as EmpowerID
Select the certificate used to sign assertions in your environment from the Signing Certificate drop-down.
Click Save.
After EmpowerID creates the OAuth Provider application, your browser should be directed to the View One page for it.
Step 2 – Add the Callback URLs to the app
On the View One page for the application, expand the Callback URLs accordion and click the Add button.
Enter the FQDN of your EmpowerID server in the Callback URL field, formatted as
https://yourserver/ui
, and then click Save.Click the Add button again and add a second callback URL, formatted as
https://yourserver/WebIdPForms/OAuth/v2
.
Step 3 – Add a client secret to the app
On the View One page for the application, expand the Client Secrets accordion and click the Add button.
In the General dialog that appears, do the following:
Name – Name of the secret
Expires – Select one of the below options:
I year
2 years
Never
Client Secret – Copy and save this value as you will use it when creating Docker secrets later in this article.
Save the secret.
On the View One page for the application, copy the values for the Client ID, API Key and OAuthProviderApplicationID. You will use these when creating Docker secrets later in this topic.
Step 4 – Configure EmpowerID System Settings for PSM
On the navbar, expand Infrastructure Admin > EmpowerID Servers and Settings and select EmpowerID System Settings.
On the EmpowerID System Settings page, search for psm.
For each setting relevant to your implementation of PSM, click the Edit button and specify the value for your environment.
The below table shows the EmpowerID Systems Settings for PSM.
Step 5 – Generate a self-signed certificate for PSM
On the navbar, expand Apps and Autentication > SSO Connections and select SSO Components.
Select the Certificates tab and then click the Add button in the grid header.
Select Generate Self-Signed Certificate and enter the following information:
Certificate Owner – Search for and select an EmpowerID Person
Prefer Local Machine Store – Select this option
Subject Name – Enter something suitable to the purpose of the certificate, such as CN=PSM_Certificate
Requires Password – Select this option
Certificate Password – Enter a password for the certificate
Click Save to create the certificate.
Step 6 – Create the PSM Service Account
On the navbar, expand Identity Administration and click People.
Click the Create Person Simple Mode action link.
In the Create Person Request form that appears, do the following:
enter a First Name and Last Name for the Person account. As a best practice, the name should reflect the purpose of the Person account.
Click the Select a Role and Location link.
Search for and select the desired Business Role from the Business Role tree.
Click the Location - link and then search for and select the desired location from the Location tree.
Click Select to select the Business Role and Location.
Click Save to save the new Person account.
After EmpowerID creates the Person object, your browser should be directed the View Page for the person.
Next, map the PSM certificate to the Person as outlined below.
Step 7 – Map the PSM Certificate
On the View page for the Person you just created, expand the Roles, Accounts, and Login Security accordion.
Click the Edit link in the Mapped Login Certificates pane.
Search for and select the PSM certificate you generated earlier and then click Save.
Extract the Key from the PFX File
To extract the private key, run the below OpenSSL command:
openssl pkcs12 -in <filename>.pfx -nocerts -nodes -out key.pem
To extract the certificate (public key), run the OpenSSL command:
openssl pkcs12 -in <filename>.pfx -nokeys -out cert.pem
