[Day 66] Cisco ISE Mastery Training: Social Media Login Integration

---

Introduction

Social Media Login (Google, Facebook, LinkedIn, Microsoft, Apple) lets visitors authenticate with an identity they already own, while you still enforce enterprise controls. In Cisco ISE, social login is implemented with standards-based federation (OAuth 2.0 / OIDC or SAML) inside a Guest WebAuth portal. The result is a frictionless lobby experience, strong auditability (who connected, when, from which social identity), and clean network segmentation (VLAN/DACL) at scale.

Key reasons this matters in ISE:

• Lower helpdesk load: no manual account creation.
• Higher conversion: fewer form fields → more successful logins.
• Better compliance: explicit consent banners + immutable logs.
• Flexible policy: treat each provider differently (e.g., Google = Internet-only, Microsoft = extended access).

---

Problem Statement

Traditional guest onboarding suffers from:

• Form fatigue (abandonment mid-registration).
• Weak identity proof (disposable emails).
• Operational friction (front-desk handling, password resets).
• Inconsistent logs (can’t tie session to a real person reliably).

We need a self-service, low-friction, identity-verifiable onboarding path that still enforces VLAN/DACL, time-bounds, and audit—with zero IT intervention per guest.

---

Solution Overview

Cisco ISE Guest portals support federated login via OAuth2/OIDC/SAML against external Identity Providers (IdPs) such as Google, Facebook, LinkedIn, Microsoft, Apple. The flow:

1. Client hits Guest SSID → WLC URL-redirects to ISE portal.
2. Guest clicks “Sign in with ” → ISE redirects to IdP.
3. Guest authenticates and consents to requested scopes (email/profile).
4. IdP redirects back to ISE with a code/assertion → ISE validates and creates/updates a guest user record bound to that social identity.
5. ISE authorizes the session (AAA override / VLAN / DACL), logs identity + device, and grants Internet-only (or more, per policy).

Sample Lab Topology

Platform: VMware or EVE-NG
Nodes:

• Cisco ISE 3.x (Admin + PSN on one VM for lab)
• WLC 9800-CL + AP (Guest SSID with L3 WebAuth)
• Catalyst Switch (L2/3)
• (Optional) AD/DNS (for sponsors, DNS resolution)
• Internet access (for IdP federation endpoints)
• Endpoints: iPhone/Android + Windows/macOS laptop

Flow (diagram description):

Requirements:

• Public FQDN for ISE portal reachable by guests.
• Trusted portal certificate (no browser warnings).
• Outbound HTTPS from ISE to IdP endpoints.

---

Step-by-Step GUI Configuration Guide

A) Prerequisites & Hygiene

1. Certificates
   • ISE GUI → Administration → System → Certificates → Certificate Settings / Portal
   • Import a public CA-signed cert covering the portal FQDN.

1. DNS/NTP—correct and synchronized.
   [Screenshot: ISE NTP/DNS Settings]
2. Firewall—allow ISE outbound HTTPS to IdP endpoints (Google/Facebook/etc.).

---

B) Create/Configure OAuth Apps on IdPs (examples)

The exact screens vary; the two constants are: Client ID/Secret and Authorized Redirect URI (copy from ISE later).

Google (OIDC)

• Create OAuth Client (Web) in Google Cloud Console.
• Scopes: openid, email, profile.
• Add Authorized Redirect URI (you’ll copy from ISE provider configuration).
• Note Client ID & Client Secret.

Facebook

• Create App → Facebook Login (Web).
• Set Valid OAuth Redirect URIs to ISE callback URI.
• Permissions: email (and public_profile by default).
• Note App ID & App Secret.

LinkedIn

• Create App.
• OAuth 2.0 Redirect URL = ISE callback.
• Scopes: r_liteprofile, r_emailaddress.
• Note Client ID/Secret.

Microsoft (Entra ID v2 / consumer)

• Register app; set Redirect URI (web) = ISE callback.
• Scopes: openid, email, profile.
• Note Application (client) ID & client secret.

Apple

• Create Services ID; configure Redirect URI; generate private key; note Team ID/Key ID/Client ID.

Keep these secrets safe—you’ll paste them into ISE.

---

C) Configure External Social Providers in ISE

1. ISE GUI → Work Centers → Guest Access → Identity Providers / Social Login (or Portals & Components → Social Providers in some builds).
2. Add Provider (e.g., Google / Facebook / LinkedIn / Microsoft / Apple).
3. Paste Client ID/Secret (or Apple key data).
4. Copy the “Redirect/Callback URL” that ISE shows → paste it back into the IdP app configuration.
5. Choose scopes (email/profile).
6. Save.
   [Screenshot: ISE Social Provider – Google (OIDC) Config]

Validation: Use “Test”/“Authorize” in ISE provider page if available to confirm OAuth handshake.
CLI quick check:

show logging application ise-psc.log | include oauth|oidc|saml|social

---

D) Build/Customize the Guest Portal with Social Buttons

1. ISE GUI → Work Centers → Guest Access → Portals & Components → Guest Portals → Add → Self-Registration (or Hotspot) Portal.
2. Portal Settings → Login Page: enable Social Login and select providers you configured.
3. Terms & Conditions / Consent: enable banners, link privacy policy.
4. Guest Type: choose a role (e.g., Social-Internet-Only-24h).
5. Look & Feel: logo, colors, text hints (“Use your Google or LinkedIn account”).
6. Save & Preview portal.
   [Screenshot: Guest Portal – Social Login Toggle]

---

E) Authorization Policy (Pre-Auth Redirect → Post-Auth Access)

1. ISE → Policy → Policy Sets → (Guest-WiFi)
2. Authentication:
   • Pre-auth device identity (MAB or WebAuth).
3. Authorization (examples):
   • IF Network Access:UseCase = GuestFlow AND Session:PostureStatus != Compliant (optional) AND SocialLoginStatus != verified → URL-Redirect to portal (Authorization Profile: REDIRECT_GUEST_PORTAL).
   • IF IdentityGroup = GuestEndpoints AND SocialProvider = Google → PermitAccess with DACL GUEST-INTERNET.
   • IF IdentityGroup = GuestEndpoints AND SocialProvider = Microsoft → PermitAccess with DACL GUEST-EXTENDED.

Tip: Store the provider name (IdP) as a session attribute (ISE does this) and branch policies per provider.

---

F) WLC 9800-CL – WebAuth Redirect & AAA Override (CLI)

Redirect ACL (allow DHCP/DNS/ISE; block the rest pre-auth):

conf t
ip access-list extended GUEST_REDIRECT
  permit udp any any eq 67
  permit udp any any eq 68
  permit udp any any eq 53
  permit tcp any host <ISE_PSNUIP> eq 8443
  permit tcp any host <ISE_PSNUIP> eq 443
  deny   ip any any
!
parameter-map type web-auth guest-social
 type webauth
 redirect exclude acl GUEST_REDIRECT
!
wlan GUEST 30 GUEST
 client vlan <guest-vlan>
 security web-auth
 security web-auth parameter-map guest-social
 no shutdown
end
wr mem

Validate (WLC):

show wlan summary
show client summary
show client detail <MAC>     ! check URL-redirect, AAA override, VLAN/DACL

---

G) End-to-End Functional Test (Engineer Playbook)

1. Connect phone to Guest-WiFi → captive portal loads.
2. Click Sign in with Google → consent → redirected back to ISE → Success page.
3. Session re-auth (CoA) → DACL/VLAN changes on WLC.
4. ISE GUI Validation
   • Operations → RADIUS → Live Logs:
     • Pre-auth Access-Accept (URL-Redirect).
     • Post-auth Access-Accept with Authorization Profile (DACL/VLAN).
       [Screenshot: Live Logs – Social Success]
   • Context Visibility → Endpoints/Users: see guest record, social provider, MAC, username/email.
     [Screenshot: Context Visibility – Social Identity]
5. ISE CLI Validation

show logging application ise-psc.log | include oauth|oidc|token|userinfo
show logging application ise-guestmanager.log | include social|federation|guest
show logging application ise-radius.log | include <client-mac-or-ip>

---

H) Hardening & Controls

• Consent & Privacy: enable T&C + privacy notice (GDPR).
• Scope minimization: request only email + minimal profile.
• Provider gating: allow only selected providers; block others.
• Time bounds: Guest Type lifetime (e.g., 8–24h).
• Segmentation: Internet-only DACL; prohibit east-west.
• Rate-limit: failed logins, portal attempts (WAF/ADC if available).
• Certificate hygiene: keep portal cert valid & chained.

FAQs

1. Which social media platforms does Cisco ISE natively support for guest login?

Cisco ISE supports Facebook, Google, LinkedIn, and Microsoft Live as OAuth/OpenID Connect providers for social login. Additional platforms may be added by configuring custom OAuth connectors.

---

2. What are the prerequisites for enabling social media login on ISE?

• Valid HTTPS certificate installed on ISE (public CA-signed recommended).
• DNS resolution configured for ISE FQDN.
• External Internet access for ISE to communicate with OAuth servers.
• A developer account/app registration on the chosen social media platform (to obtain Client ID & Secret).

---

3. How does Cisco ISE authenticate users with social media credentials?

When a guest selects a social login option, ISE redirects them to the OAuth provider’s login page. After authentication, the provider sends an OAuth token back to ISE. ISE validates the token and maps the user identity into its internal guest identity store for access policies.

---

4. Can we customize the Guest Portal login page to show only selected social media logins?

Yes. Under Guest Access → Guest Portals → Portal Page Customization, you can enable/disable individual login options (e.g., show only Google & Facebook). Branding, logos, and text can also be customized.

---

5. How do we validate if OAuth redirection and token exchange are working properly?

• On ISE GUI → Operations → RADIUS → Live Logs: Check authentication flow.
• CLI validation: show logging application ise-psc.log show logging application ise-psc-oauth.log These logs display OAuth redirection, token validation, and any errors from social media APIs.

---

6. What happens if a user’s social media account has two-factor authentication (2FA)?

2FA is enforced by the social media provider. ISE simply redirects the user; if the login succeeds with 2FA, ISE accepts the OAuth token. This makes ISE automatically compatible with MFA-enabled accounts.

---

7. How can engineers map social media login attributes to authorization policies?

Attributes like email, name, or unique user ID returned in the OAuth token can be extracted and mapped in Authorization Profiles. Example: Users with Gmail (@gmail.com) can be assigned to a “Guest-WiFi” policy, while corporate-linked accounts may get higher privileges.

---

8. Is it possible to restrict access to only corporate-approved social media domains (e.g., @company.com Google accounts)?

Yes. During Authorization Policy creation, you can set conditions that check the email domain attribute returned by OAuth (e.g., allow only @company.com, deny @gmail.com).

---

9. What are the troubleshooting steps if social login fails at redirect?

• Ensure correct Client ID/Secret configured in ISE.
• Verify redirect URI in social media app registration matches ISE portal URL.
• Check firewall rules (ISE must reach external OAuth endpoints).
• Validate DNS resolution for both ISE and OAuth provider domains.
• Review ise-psc-oauth.log for OAuth handshake errors.

---

10. What are the security concerns with enabling social media login in Cisco ISE?

• Users bring unmanaged devices authenticated only by external credentials.
• Risk of account hijacking if social login credentials are compromised.
• Logging & monitoring are essential: ISE administrators must enable RADIUS logs, CoA actions, and reporting for social login sessions.
• Recommended to combine social login with endpoint profiling or posture assessment for better control.
