Community College Internal Auditors Implementing User’s ITSecurity Access Control 2011 Spring Conference Presented by: Emmie Oesterman, IT Auditor Kris Backus, Sr. IT Analyst
Background • LRCCD includes four colleges and eight education centers. • More than 90,000 students are enrolled in our colleges • LRCCD uses PeopleSoft Enterprise Resource Planning (ERP) System for: • Student Administration (1200+ users) • Financials (150+ users) • Human Resources (100+ users)
Findings – Internal Auditor • PeopleSoft security is inadequate. • Management made it a priority to redesign our user’s access and granting procedures.
Findings – External Auditor Internal Control (Information Technology) • Our observation and testing of controls over computer systems access indicated a number of conditions including duplicated profiles for users, users with more than one role, and terminated employees still active in the financial system. While we did not identify any financial statement errors or irregularities resulting from these conditions, stronger controls are necessary. • Financial Statement Audit – FY07/08 • Resolve in FY08/09 Audit
Plan • Student Administration • Highest number of users (1200+ users) • Greatest risks • Financials • 150+ users • Human Resources • 100+ users
The Team • IT Staff • IT Auditor • District/College Staff* • District/College Information Security Officers* * When needed
Goals • Determine the current roles and security access. • Develop appropriate roles and security to assure adequate security and privacy of data.
Goals (continued) • Provide user documents to clearly identify the access within each PeopleSoft role. • Develop new business process to appropriately grant access and provide accountability.
Goal 1 Determine the current roles and security access. • IT ran a script to provide detailed listing of access within each role. • The team analyzed the data and determined appropriateness. • IT deleted any unused access.
Goal 2 Develop appropriate roles and security to assure adequate security and privacy of data. Access Methodology • Data Ownership • Hierarchy
Goal 2 Data Ownership • Determine data owners • Design an approval process based on data ownership. Example:
Goal 2 Hierarchy: • Roles are created on a hierarchy system. Higher level access will include the access of all lower levels. • Example • SR Access III will include all the access from these roles: • Student Info View I • Student Info View II • SR Access I • SR Access II
Goal 3 Provide user documents to clearly identify the access within each PeopleSoft role. • Definitions of Roles • Mapping of old to new roles • Red Flags for Approvers • Notes for Approvers • Security Reports
Goal 3 Definitions of Roles
Goal 3 • Mapping of old to new roles
Goal 3 Red Flags for Approvers

Goal 4 Develop new business process to appropriately grant access and provide accountability. • Request Process • Determine the process where users can request access to PeopleSoft. • Approval Process • Determine the appropriate authorized personnel for approval of access requests. • Granting Process • Determine who will process the access requests.
Goal 4 • Request Process: • Paper Form (Phase 1) • Form can be printed and submitted via mail or e-mail (using email address as the electronic signature) • Online Access Requests (Phase 2) • Users log onto the Security Access System (SAS) to request access.
Goal 4 • Approval Process: • Authorized Signer List • List the authorized signers who can approve PeopleSoft access • Two level of approvers • Level 1: View only access • Level 2: Update/Correction access
