5 Challenges in Healthcare Virtualiza?on Management Applica?on Performance Event Log Correla?on Global View of Environment

6 Hospital s Visibility Gap Not easy to navigate Windows event viewer Log by log review for troubleshoo?ng Manual event correla?on spanning mul?ple systems No log access when host down or off network Hours/days to find root cause(s) for end user device issues Wasted (me and effort to track down issues

7 Steps to success: Splunk Solves Visibility Gap 1. Downloaded free demo 2. Globally installed Splunk Universal Forwarders on Windows server and client opera?ng systems 3. Indexed Windows event log data 4. Instantly gained visibility into Windows environment like never before Troubleshoo(ng (me now a frac(on of what it used to be

8 Splunk in Produc=on Finding new use cases EVERY DAY!! Audit consolida?on One tool to monitor all systems Event correla?on Is the issue happening everywhere? When? Recognize anomalous ac?vi?es Something strange going on? Add new log sources See what shakes out No need to purchase addi(onal products. Index the data in Splunk.

9 Success Stories Mystery wireless disconnects persisted for years. Using Splunk searched on User ID / tablet name at drop?mes. Discovered crashing process on Citrix server at dropping event?me! Wireless disconnects reported HERE Root cause was back end service crashing in datacenter

10 What computer am I connected to? Mystery name resolu?on issues. Connec?ng to wrong worksta?ons when using hostname. *error* search found DNS record scavenging was accidentally off aner AD/DNS server migra?on. Want to connect to PC A Helpdesk But get connected to PC B

11 Finding a Botnet Index firewall traffic logs using Splunk and Google Maps Discovered a health library machine connected to an interna?onal botnet No business need to communicate with Peru

12 Boot Times Table

13 Found File Dele=on Incident User files vanish with no insight from file audit tool Search for user id AND delete finds over 300 events in an hour over the weekend User accidentally deleted one too many folders

14 Blocking streaming HDTV through Firewall

22 Windows NPS RADIUS Dashboard

23 Print Server Log Dashboard

24 Print User to IP Correla=on Print logs do not contain where user prints from. Windows Event logs show where user last logged in.

25 Viral Spread of Splunk Word of Splunk s capability to audit systems and solve mysteries trickled through other IT staffers. Addi?onal systems I didn t even know we had were added to Splunk.

26 IT Director s Challenge A system to audit our Electronic Health Record access. A single solu?on to audit mul?ple systems. Easy to manage. Cost is always a factor. We have two op?ons. Which one is beher? The answer: Op?on 3 Splunk!

27 Pa=ent Privacy & Meaningful Use

28 EMR/EHR - Electronic Pa?ent Records Healthcare Jargon PHI/ePHI (electronic) Protected Health Informa?on HIPAA - The Health Insurance Portability and Accountability Act of 1996 HITECH Act - Health Informa?on Technology for Economic and Clinical Health Act Meaningful Use Goal is to not just adopt an EHR, but to leverage it to achieve significant improvements in care Cerner - Middlesex Hospital s Primary EHR Results Middlesex Hospital s home grown EHR lookup applica?on eclinicalworks Middlesex Hospital s Primary Care / Family Prac?ce / Mul?specialty EHR McKesson Homecare Middlesex Hospital Home care EHR GE Flowcast Pa?ent registra?on/demographics Lawson Employee Database

29 Electronic Health Record Audi=ng Federal reimbursement for having cer?fied technologies to audit Electronic Health Record (EHR) access, Meaningful Use Requirement Splunk v6.0 is currently v1.0 Cer?fied (for both Ambulatory and Inpa?ent) (d)(3) - Audit report(s) EHR provider offers specialized (and expensive) point solu?on Other EHR vendors couldn t correlate between systems/databases Other vendor solu?ons specific to their product. Can t build intelligence.

30 Splunk for MU2 EHR Module, 2014 Edi=on means EHR technology that is cer?fied to at least one of the 2014 Edi?on EHR cer?fica?on criteria for either the ambulatory or inpa?ent prac?ce sepng. An EHR Module could provide a single capability required by one cer?fica?on criterion or it could provide all capabili?es but one, required by the cer?fica?on criteria for a Complete EHR. Splunk is 1 of 20 modules required to meet Base EHR defini?on for 2014 Edi?on EHR cer?fica?on (d)(3) Audit reports Required (g)(4) Quality Management System Needed for all modules Splunk will not fulfill your EHR product cer?fica?on alone, but will check the (d)(3) Audit Report(s) box on the cer?fied health IT product list: hhp://oncchpl.force.com/ehrcert/ehrproductsearch or hhp://goo.gl/5pshd

31 Primary vendor solu=on EHR Vendor Audit Repository Data Inputs Similar in ability to Splunk Much more expensive to implement Very lihle if any community support New inputs require vendor services to implement Data elements have to be pre- programed into repository

32 Other vendor solu=ons Each system has its own audi?ng capabili?es (maybe) No way to centrally look into all system access. Log into each app to run access reports Advance inves?ga?ve dashboards unavailable, limited, or costly to implement

33 Taking a stab at an EHR audit App Newbie Splunk user s first App Cerner audit data only PoC rolled into preliminary App Much development needed Worked well enough to sa?sfy audi?ng requirements

34 Challenges in building the App First of it s kind in Splunk I am not a compliance officer I am not a developer Limits on my?me Only IT staffer with end game in focus

49 Splunk & Compliance " Re- dran our policies on regarding what a HIPAA viola?on actually is. " Create policies regarding how we will move forward with Splunk & HIPAA Privacy and Security Scout app. " Will we survive an audit? We have the power. Use it! " Educate the masses. Goal is for Splunk to find nothing. 49

50 Barriers to Progress " Beher at finding poten?al viola?ons. Takes more?me to inves?gate. Splunk is too good! " EHR vendors don t supply enough audit info to automate more. " Finding the informa?on with DB Connect takes lots of?me. Hope the schema doesn t change! " Vendors unable/unwilling to co- operate. 50

51 Vision into Our Future NOW Compliance Officers, Auditors, Applica?on Staff, Opera?ons Team, Infrastructure Team Splunk search heads with TAs (Technology Add- ons) and a Common Healthcare App Splunk indexing mul?ple diverse, but related systems EHR, Finance, Infrastructure, Clients, Servers, Systems, the list goes on.

52 Lessons Learned Budget for servers/storage. Don t roll PoC into produc?on system. Start fresh. Sync?mes before indexing (where is that s?nking real?me data?). Expect to frequent answers.splunk.com if you want to be successful. When inges?ng data, it helps to have friends on the inside. If I had known then what I know now
