Process
Change Management Process
◦ Reinvigorated need for approvals prior to modifications
◦ Clarified definition of a “change”
Governance
◦ Senior Management review and approval for each change to monitoring
profile once in production
◦ Clear communication on additional volume of work created
◦ Opportunity to focus on groups that were less compliant
Monitoring rules
◦ Accepted Tripwire as a recognized expert and used the published rules as often as possible (OS,
database …)
◦ Avoided historic pitfalls of internal debates to merits of monitoring critical items
9/6/2018 8

People
Policy created to support effort
◦ Initially Change Management
◦ Added PCI compliance as Tripwire became viewed as critical success factor
Meetings with technical teams
◦ Often “selling” effort one person at a time
◦ Open and honest discussions
◦ Focus on real purpose of monitoring
Auditing
◦ Remediation notes
◦ Change orders
◦ Matching criteria
9/6/2018 9

Technology
Integration into ITSM Tool
◦ Used to validate approved change orders
◦ Remediation becomes component of daily routine obligations
◦ Change detection, File integrity monitoring and Vulnerability Notifications
Rule Tuning
◦ Focus on most critical elements leveraging data analytics
◦ Often used features to identify “normal” activity limited to a specific account
to reduce volume of alerts
Reporting
◦ Reporting to application owners during rule development phase
◦ Reporting attached to each incident showing the details of modifications
◦ Reporting to Governance group for volume of activity
◦ Reporting to internal auditors to demonstrate good faith effort and help focus auditing efforts

efforts
 Expansion from Change Detection to also include File Integrity Monitoring and Threat Detection
 Visibility and monitoring for Epic Financial data
 Better visibility and governance around change management
