OpenID Connect Protocol
• Interoperable authentication protocol
• Based on OAuth 2.0 family of specifications
• Uses REST/JSON message flows
• Design goal is “making simple things simple and complicated things possible”

OpenID Connect Components
• Identity Provider (IDP) - offers user authentication as a service
• Relying Party (RP) - outsources its user authentication function to an IDP
• Web site
• Application

Is OpenID Connect similar to SAML2?
Diagram from http://docs.oasis-open.org/
SAML vs OpenID Connect
• Security Assertion Markup Language (SAML)– XML-based protocol– Older protocol: 2005 (SAML2)– High rate of adoption– Designed only for Web-based applications
• OpenID Connect – JSON/REST based protocol– Newer protocol: 2014– Designed to support native apps and mobile
applications
OpenID vs OpenID Connect
• OpenID 2.0
– Uses XML and a custom message signature scheme
– Difficult to create interoperable applications
• OpenID Connect
– Uses standard JSON Web Token (JWT) data structures
– Better interoperability
OAuth 2.0 vs OpenID Connect
• OAuth 2.0 is an authorization framework– Provides message flows based on JSON and HTTP
https://oauth.net/articles/authentication/
• OpenID Connect is an authentication protocol– Uses OAuth 2.0 flows and services
– (Identity, Authentication) + OAuth 2.0 = OpenID Connect
OpenID Connect Implementation
• Certified Relying Party (RP) Libraries– Apache HTTPd server– .NET Nuget Package – Erlang– JavaScript – PHP– Python – …
http://openid.net/developers/certified/
OpenID Connect Implementation
• Certified Identity Provider (IDP) Libraries
– Gluu Server
– MITREid Connect
– Keycloak
– …
http://openid.net/developers/certified/
Keycloak
• Open source Identity and Access Management solution
http://www.keycloak.org/about.html
• Provides Single-Sign On (SSO)
• RedHat SSO is based on Keycloak
https://access.redhat.com/solutions/1472293
Keycloak IDP
• Based on WildFly server
– Server Administration
– Clustering
• Supports custom look and feel (themes)
• Supports custom authentication (providers)
• Can authenticate users with external OpenID Connect or SAML 2.0 Identity Providers
Keycloak Relying Party (RP)
• Keycloak calls them adapters• Out-of-the-box support includes
– Spring Boot– Spring Security– Node.js– …

Keycloak Brute Force Protection
What is a brute force attack?
“A brute-force attack is an attempt to discover a password by systematically trying every possible combination of letters, numbers, and symbols until you discover the one correct combination that works”
https://www.owasp.org/index.php/Blocking_Brute_Force_Attacks
Keycloak Brute Force Protection
• Preventing automated attacks:– Lock after 2 subsequent login failures
– 1 second between failures (too quick for a human)
– Lock remains active for ~5 min
• Preventing manual attacks:– Lock after 30 subsequent login failures
– Sliding window of 12 hours
– Lock remains active for ~ 45 min
Keycloak Password Policy
What is a password policy?
A Password Policy is the set of restrictions and/or requirements that a user must follow to ensure that their password is strong.
Keycloak Password Policy
Keycloak policy types include:• Digits – minimum number of digits required• Special Characters - minimum number of special
characters required• Expire Password – password expires after n days• …
http://www.keycloak.org/docs/3.2/server_admin/topics/authentication/password-policies.html
Summary
• Enforce a strong authentication scheme
• Immediate support for advanced security features
• Brute force protection
• Password policy
• Leverage future IDP enhancements
