 Virtual Private Network  Provides an encrypted tunnel between a client computer and a remote network  Remote termination proxies the connection to other resources  All or some traffic routed to remote network

VPN Operation JMU Border VPN terminal

 Gain remote access to applications and data deemed too sensitive to expose directly to the Internet ◦ Student Administration system  Gain remote access to resources licensed to JMU by IP address ◦ Microsoft site license ◦ Online library resources

 Required a client ◦ No support for new OSes ◦ No support for mobile devices  Tunneled all traffic over UDP ◦ All traffic had to go through JMU, even if not destined for JMU  Access required configuration on firewalls  Rapidly approaching end-of-life

 Support for newer OSes  Support for mobile devices  Uses web browser for basic access  Java clients for advanced access  LDAP or Active Directory authentication  Access granted based upon roles

 Web Connect  WSAM/JSAM  Network Connect  Junos Pulse (Mobile clients)

 Default connection  Provides access to: ◦ Web resources ◦ File Access ◦ Remote desktop ◦ SSH access  Solution for most connections at JMU

 Windows only  Java program or Activex control  Inserts a shim into the network stack  Network access to preconfigured resources are directed through the VPN  Resources MUST be preconfigured on the VPN

 Java based proxy  Maps local port to remote destination through the SSL VPN ◦ Example: hrweb.jmu.edu:443 is mapped to local port 8000 ◦ Connections to is forwarded to hrweb.jmu.edu:443  Either WSAM or JSAM per role, not both  Not currently used at JMU

 Most impact on JMU and client system  Java application  Behavior similar to existing Cisco VPN: all traffic is routed through the VPN to JMU’s network

 Network Connect for mobile devices  All traffic tunneled through the VPN  Untested

 Network resources that users are allowed or denied access to  Identified by host and port, subnet, URI, etc  Can be specific enough to allow access to parts of a website while denying access to others

 Group of people that share similar access  Role membership can be identified by LDAP group membership or attribute  Role membership can be enumerated within the SSL VPN ◦ Most roles are enumerated ◦ Want to move to LDAP/AD as identity management matures  Users are often assigned multiple roles

 Logical container containing authentication source and login pages  May be accessed either by a new domain name or by a new URL ◦ ◦

 Roles are added to a realm ◦ Roles may be in more than one domain  Resources are added to roles ◦ Both permit and deny resources are added ◦ Default deny of access to unmentioned resource ◦ Users accumulate resources from each role they’re assigned to

 Moving from enumerated roles to group/attributes in a directory  Identifying resources that don’t work with web connect and developing workarounds ◦ Internal JMU applications ◦ Externally licensed resources (750+ through the library alone)

 Endpoint Security ◦ Malware protection ◦ Antivirus version monitoring ◦ Patch management monitoring  Cache Cleaner  Two-factor authentication ◦ One-time passwords ◦ Certificates  Single Sign-on  Restrictions to access from certain subnets  Restrictions to browsers
