Browser Web and application servers iChain Proxy Server iChain Authorization Server 1. Authentication—Who are you? 3. Single Sign-on Security 2. Access control—What do you have access to? 4. OLAC (Personalization) 5. Data confidentiality User=xx Password=xx Books=Thrillers, Horrors Novell iChain—How Does It Work?
Browser Web and application servers iChain Proxy Server iChain Authorization Server Domain-Based Multi-Homing Access Multiple Services through One Public IP Address DNS Entry support.novell.com developer.novell.com Browser sends in HTTP host header
Authentication Service Standard browser-based access (no client) No agents required on web servers Multiple authentication methods (multi-factor) LDAP—UserID/password ( address or any LDAP field) X.509 Certificates Token (RSA, Vasco, Secure Computing)—dependent on RADIUS UserID and password sent over HTTPS (HTTP optional)
Authorization Services Access control Leverages eDirectory hierarchy and inheritance Access based on rules stored in eDirectory (cont.) Three different levels available –“Public” —no authentication or access control –“Restricted” —authentication only –“Secure” —authentication and access control Access rules may be assigned to Users Groups Containers (O, OU, etc.)
Dynamic Access Control Adds greater flexibility to satisfy security policies Access based on identity information Example “Object type=User” AND “Description=Manager” Dynamic Access Control rule
Single Sign-On/Personalization iChain Proxy forwards user information to backend web servers—utilizes object level access control Used for Single Sign-on ICHAIN_UID and ICHAIN_PWD can be mapped to any LDAP field (allows different names/passwords to be sent to web server) Used for personalization Sends “Parameter=Values” (retrieved using LDAP) Form fill authentication Stores credentials entered by user (Novell SecretStore ® ) Automatically fills form on next request
Data Confidentiality Secure exchange Secure transparent (on the fly) encryption Eliminates the need to use SSL on web servers Increases performance of web server Decreases management tasks SSL encryption strength Force 128-bit connections No cache setting
User and Access Management Browser-based utilities to change user profile information and passwords Leverages eDirectory restrictions Time restrictions, intruder lockout, password history, password expiration and grace logins Offers enhanced password management features Non-dictionary words, minimum number of numerals /characters
iChain 2.1—User Certificate Mapping Why do we need this? iChain must know the distinguished name of the user to enforce access control Third-party certificate authorities will very rarely distribute certificates with this information in a correct format What does it do? Provides a mapping between the information held in the certificate to the user’s distinguished name
iChain 2.1—User Certificate Mapping How is it configured?
iChain 2.1—Custom Re-Writer Why do we need this? When hiding internal DNS infrastructure, the browser must know how to get to services using the public DNS information The default iChain re-writer will automatically change most of the relevant content as is passes through the proxy Certain web applications (Oracle) hard code DNS information into its data stream This must be identified and changed
iChain 2.1—Custom Re-Writer Browser iChain Proxy Server Finance.novell.com Oracle.prv.novell.com Without custom re-write
iChain 2.1—Custom Re-Writer Browser iChain Proxy Server finance.novell.com Oracle.prv.novell.com [Name=oracleFilter] [Extension] Html, htm [Replace] PARAM name=servHost Value=finance.novell.com finance.novell.com With custom re-write
iChain 2.1—Custom Login Pages Custom page for each accelerator
iChain 2.1—Custom Cert Error Page Why do we need this? Accelerator configured to require a certificate User has no certificate—presses Cancel, goes to a blank page User has no idea what to do next
iChain 2.1—Session Broker Increases scalability of iChain infrastructure Shares authentication information between proxy servers Browser Session broker
