OSG PKI Contingency and Recovery Plans Mine Altunay, Von Welch October 16, 2012

WLCG Management Board Background The Open Science Grid (OSG) relies on a public key infrastructure (PKI) built around an OSG Certificate Authority (CA) to support its operations. The OSG PKI is operated by two parties:  The OSG itself operates a network of trusted agents (registration authorities and grid admins) who vet certificate requests and a web front-end OSG Information Management (OIM) System that provides interfaces for users for PKI functions  The DigiCert, a private company, operates the CA that, at direction of OSG and within the bounds of policy, performs the issuance of certificates. 2

October 16, 2012WLCG Management Board Goals and Scope Create a Recovery Plans document that present a recovery plan for PKI failure scenarios. Not a risk analysis, does not attempt to analyze whether or not a PKI failure is something that the OSG should prepare for. Analyzes the options for a recovery plan and recommends a broad course of action. Describes all the steps necessary to bring the OSG PKI back to its normal functional state. Focuses on the new OSG PKI, not the DOEGrids CA although most of the discussion is valid for DOEGrids CA as well. 3

October 16, 2012WLCG Management Board OSG PKI Failure Cases 2 Failure Types: compromise and loss of service  Back-End CA Compromise  OSG Information Management (OIM) Front-End Compromise  Back-End CA Loss of Availability  OSG OIM Front-End Loss of Availability 4

October 16, 2012WLCG Management Board Recovery Plans A recovery plan for each failure type is presented in the document available at docdb.opensciencegrid.org/cgi-bin/ShowDocument?docid=1121. The plan: docdb.opensciencegrid.org/cgi-bin/ShowDocument?docid=1121  Is a workflow of specific steps that should be taken in the aftermath of a failure to restore PKI back to normal. E.g., forming the incident response team, revoking compromised certs, issuing replacement certs, community communications, and so on.  Considers slight variations in a failure type depending on the different levels of severity (e.g. all RA Agents compromised vs. only some are compromised), incorporates conditional branches into the workflow. 5

October 16, 2012WLCG Management Board Recovery Plans  Each step is accompanied with specific timelines, estimating how long the plan execution would take.  Each step has a clear owner responsible for performing the activities in the event of a failure. Due to time limitation and the complexity of each plan, I will not present them here. Please contact me and Von Welch should you have any questions or feedback. 6
