CREN Certificate Authority Project: Update from Georgia Tech Ron Hutchins 28 March 2000

Progress Application for Certificate is done CREN certificate has been created and is installed in the Georgia Tech Certificate Authority offline Security Policy Committee for the campus has met two times to begin discussions. Applications utilizing the certificates are under way Document, document, document

Why Certificates? Current apps have no common authentication and authorization model. Need for a common layer of AAA to reduce complexity for growth. Certificates in conjunction with SSL, IPSEC, and Kerberos provide a model for a significant number of applications both current and future

Plan Create GT Certificate Authority - done Interface with Kerberos to create initial instance of a Registration Authority - done Create practices for managing the CA - in progress Create classes of certificates and define use and appropriate lifetimes - soon Define apps and appropriate cert model - coming Create and document local policy - in parallel Educate our constituency - forever

Applications Remote Access - from any ISP into campus Authenticated wireless and walk-up access SSL encryption and logging via 2-way certs on web enabled apps (WebObjects, etc) Secure ? Via SSL or Kerberos? Or certs directly?

Middleware needed? Interfacing with Kerberos as Registration Authority for class 3 cert issuing application via web - Jeff Schiller model - current but needs some hardening… Create our Registration Authority for other cert classes? LDAP interfacing for CRL and Public Key storage/access FreeSWAN mods to accept certs for VPNs on Linux? Other platforms?

Futures Work with State governmental agencies in Georgia and beyond Work with University System Board of Regents for Education model of security Work with JSTOR for certificate based authentication for faculty access to databases

To Be Done... Designate classes of certs for campus use: –Class 1 - business office and finance class? –Class 2 - general GT server certificates? –Class 3 - remote access and student general purpose only (if we issued a cert it’s good for something) Designate lifetimes for these cert classes Create CRLs and LDAP interfaces to complete the model (Middleware) Create apps that really check expiration and CRLs Policy stuff… and documentation
