PeopleSoft SSO – Single Sign On Solution

PeopleSoft SSO Integration Options

Why is PeopleSoft SSO important?

PeopleSoft SSO is most desired for PeopleSoft Portal implementations, as PeopleSoft Portal is the central and unified interface to access other PeopleSoft Applications, such as HCM or CRM. PeopleSoft SSO authenticates the user during the first login to PeopleSoft Portal, then allows the user to access other PeopleSoft Applications without forcing the user to login to the each application over and over. Therefore, SSO is a must have for PeopleSoft Applications.

Security Concerns with PS_TOKEN – TokenChpoken Attack

Oracle PeopleSoft offers Single Sign On – SSO out of the box to offer the better user experience for its customers. This out of the box PeopleSoft SSO uses PS_TOKEN cookie to store the user or session information to pass from PeopleSoft Application to another.

PS_TOKEN cookie stores confidential information such as UserID – Name of the Authenticated User, Node Name – Node Name Authenticated the user, Date And Time – when the PS_TOKEN was issued, and SHA Signature in base64 encoded.

According to ERPScan report about Oracle PeopleSoft vulnerabilities, PeopleSoft Applications are susceptible to the TokenChpoken attack, which affects systems that use Single Sign On SSO, is possible because an PS_TOKEN Authentication cookie used by PeopleSoft Applications can be forged. When the PS_TOKEN is identified by a “brute force” TokenChpoken attack, it is possible to log in under a system account and gain access to all data from the compromised system. Read more at:

Understanding PeopleSoft Single Sign On

Solution for PS_TOKEN TokenChpoken Attack Vulnerability

  1. Disable out of the box SSO from PeopleSoft to eliminate PS_TOKEN completely.
  2. Enable External SSO for PeopleSoft with solutions such Microsoft Azure, CA Siteminder, Okta, Oracle Access Manager, and SSOGEN.
  3. Enable Multi Factor Authentication – MFA for PeopleSoft Applications
  4. Enable External SSO for all PeopleSoft Applications for seamless access

How to enable PeopleSoft Single Sign On?

Reverse Proxy

Configure Apache or Oracle HTTP Server Reverse Proxy to front-end all the PeopleSoft Servers, proxying /psp/, /ps, /psc, amd /cs URIs.
 
 

Disable Direct Access

Ensure that all the traffic is routed through the above webserver and Disable direct access to PeopleSoft Server URLs.
 
 

Enable External SSO

PeopleSoft SSO Configuration

Logon to Peoplesoft Console http://ps.example.com:8000/psp/ps/?cmd=start using Admin credentials(Example: PS/PS).

PeopleSoft Single Sign On Integration

Navigate to Peopletools >> Security >> User Profiles >> User Profiles to create a new user profile, for example: OAMPSFT and Add Peoplesoft User.

PeopleSoft Single Sign On Integration

Peopletools >> Security >> Security Objects >> Signon PeopleCode – Uncheck all options and check ‘OAMSSO_AUTHENTICATION’.

PeopleSoft SSO Configuration

In Application Designer, Click Open and Select ‘Record’, and Open ‘FUNCLIB_LDAP’ and click Open.

PeopleSoft SSO Configuration

Update Peoplecode of LDAPAUTH for getWWWAuthConfig() function to update defaultUserID to OAMPSFT that we have just created.

PeopleSoft SSO Configuration

Update the user Header with PS_SSO_UID for OAMSSO_AUTHENTICATION function. SSOGEN_USER is another header variable, which is good for this function. SSOGEN_USER is available out of the box for SSOgen Integrations.

PeopleSoft SSO Configuration

Restart PeopleSoft Services and perform SSO Login use cases.

Function OAMSSO_AUTHENTICATION()
   If %PSAuthResult = True And
         &authMethod <> "LDAP" And
         &authMethod <> "WWW" And
         &authMethod <> "OSSO" And
         &authMethod <> "SSO" Then
      getWWWAuthConfig();
      If %SignonUserId = &defaultUserId Then
         &userID = %Request.GetHeader("PS_SSO_UID");
         If &userID <> "" Then
            If &bConfigRead = False Then
               getLDAPConfig();
            End-If;
            SetAuthenticationResult(True, &userID, "", False);
            &authMethod = "OAMSSO";
         End-If;
      End-If;
   End-If;

  3. Let me understand this better.. do you guys offer a free multi-factor authentication?

    Reply
  4. Yes, SSOgen offers a free multi-factor authentication app for iOS and Android to all of its customers. The soft token from the mobile app acts as a second factor for MFA SSO here.

  5. So, this solution addresses PS_TOKEN security vulnerability issue?

    Reply
  6. Yes, as mentioned above, this solution eliminates the need for PS_TOKEN completely.

  7. Does this integration need OID License from Oracle?

    Reply
    • Thomas,

      No, this solution does not use OID or OAM.

  8. This solution works with Azure AD authentication, which is in Microsoft Azure Cloud?

  9. PeopleSoft can be SSO enabled with CA Siteminder SSO with this gateway? Our IT Security team does not support SAML Authentication for PeopleSoft..

    Reply
    • Yes, Siteminder SSO is enabled through SSOgen SSO Gateway, and it does not require CA Federation – SAML Services. Please reach out to info@ssogen.com for a quick proof of concept.

  11. How long would it take to implement SSOgen for PeopleSoft?

    Reply
    • Typical SSO implementation takes about 30 minutes for PeopleSoft.

  12. Do we need LDAP Directory for SSO Integration

    Reply
    • LDAP Directory is not required, as SSO is configured to authenticate users with Azure AD, Oracle IDCS, Okta, or PING SSO.

      However, if customer wishes to host some users in SSOgen, we offer a free directory.

  13. You say that dependency on PS_TOKEN is completely eliminated.

    But what happens in a cluster setup (like in our organization, we have HCM, FSCM, ELM) and functionalities like
    1. Unified Navigation
    2. Remote Tiles
    3. Cluster Elastic Search (Setting up a global search, where results are rendered across multiple instances)
    4. Cluster Approvals
    5. Push Notifications

    that require the PS_TOKEN/Single Signon configurations to be in place?

    Reply
    • Though PS_TOKEN is used internally, all the PeopleSoft URLs are going to be protected by a SSO Client[Web Server Plug-in] in the web server.

      Reply
  14. Does it work with Okta Verify?

    Reply
    • Yes, Okta Verify is fully compatible with PeopleSoft SSO Logins, via SSOgen SSO Gateway.

      Reply
  15. Is this based on HTTP Header injection?

    Reply
    • No, this is not based on HTTP Header Injection coming from a network device.

      SSOgen SSO Client (Web Server Plug-in) acts as a SSO Policy Enforcement Agent, and any HTTP headers injected by the user/browser/network devices are discarded by the SSO client sitting on the web server.
