  2. Parm Lalli Director, Data Analytics Focal Point Data Risk, LLC Parm is a Director with Sunera and leads our national Data Analytics practice. Parm has over 14 years of data analytics, audit, and controls experience with Sunera and other IT consulting firms, and is widely considered a leading data analytics practitioner in North America. Parm’s data analytics expertise includes vast experience with various Computer-Aided Audit Tools (CAATs), leading and performing data analytics and developing continuous controls monitoring (CCM) applications for many business processes. His experience also includes installing, implementing and configuring ACL Analytics Exchange, and providing training on all aspects of data analytics, from basic functionality to complex scripting and controls monitoring. Parm’s 16 years’ experience with ACL Software includes six years working at ACL. During Parm’s time at ACL, he led the development of analytics for ACL’s CCM solution. These analytics covered risks associated with accounts payable, travel and entertainment, general ledger, order to cash, procurement, human resource and payroll. Once the analytics were developed, Parm led consulting projects for ACL clients where he implemented the analytics and assisted clients with the development and maturation of the data analytics and CCM programs. Parm has also worked at PricewaterhouseCoopers in the Advisory group where he performed Revenue Assurance consultancy with the Telco Industry. Parm also have extensive experience with other data analytics tools and applications such as TOAD for Oracle & SQL Server, Arbutus, and Alteryx. In addition to his data analytics focus, Parm’s background is IT audit focused, having provided services related to IT general controls, application controls, internal audit, IT risk assessment, process improvement advisory, operational audit and Sarbanes-Oxley Act (SOX). Parm has also been involved with conducting vulnerability assessments and penetration testing for clients. Parm is a Certified Information Systems Auditor (CISA) and ACL Certified Data Analyst (ACDA). 2

  3. OBJECTIVES ▶ Raise awareness of the contribution data analytics can make to mitigate risks in IT ▶ Identify key risk areas that can be tested with data analytics tools ▶ Describe data analytics tests for key high-risk areas 3

  4. AGENDA ▶ Why data analytics for IT? ▶ Risks to mitigate ▶ Specific risk areas ▶ Data Analytics for Cybersecurity ▶ Proactive security monitoring 4

  5. Why data analytics for information technology?

  6. 2014 Data Breach Statistics ▶ $3.8 million per organization* ▶ $154 per record* ▶ Increases in ▸ Cyberattack frequency ▸ Remediation costs ▸ Business impact ▸ Detection/escalation costs * IBM/Ponemon 2015 Cost of Data Breach Study 6

  7. The Environment ▶ High-risk area ▶ Abundance of data ▶ Multiple platforms/formats ▶ Complex ▶ Decentralized ▶ Proliferation of unencrypted devices 7

  8. DA enables… ▶ High-frequency automated testing ▶ Development of metrics ▸ Operational performance ▸ Call centers ▸ Cybersecurity ▶ Close to real-time monitoring/reporting of risks ▶ Comprehensive overview 8

  9. Output ▶ Dashboarding of trends/metrics ▶ Drill-down capabilities for supporting data ▶ User-friendly formats 9

  10. Risks

  11. Risks ▶ Unauthorized activity ▶ Loss of revenue ▶ Data corruption ▶ Data leakage (accidental) ▶ Data theft (intentional – internal or external) ▶ System downtime ▶ Loss of confidentiality ▶ Erosion of process integrity ▶ Decreased performance ▶ Malfunctioning hardware 11

  12. Risk Areas

  13. Key Risk Areas ▶ Access ▶ Change logs ▶ Segregation of duties ▶ Change management ▶ Physical access ▶ General Computer Controls/ITGC ▶ Application controls ▶ Improper user of company assets (Policies) 13

  14. Access ▶ Elevated access review ▶ Usage of Admin/Super user accounts ▶ Compare access to position description ▶ Compare to previous review results ▶ Flip flop access privileges ▶ Segregation of duties ▶ Access to contractors ▶ HR payroll records vs Active Directory user listing 14

  15. Change Logs ▶ Review major changes ▶ Identify change/reversion (“flip-flop”) ▶ Frequency distribution by individual or department ▶ Audit logs for application and database changes 15

  16. Change Management ▶ Compare to ITAF standards ▶ Proper categorization ▶ UAT results ▶ Test all environments to ensure proper change management (Dev, Test, Prod) ▶ Use DA tools for Code Review ▶ SOX controls for Vendor Master / Customer Master changes 16

  17. Physical Access ▶ Review entries/exits to data centers (who) ▶ Review entry times vs exit times (duration) ▶ Cross-reference with HR data for departing employees ▶ Compare against logs for suspect events ▶ Review temporary access passes for approvals ▶ Review failed attempted access logs 17

  18. General Computer Controls/ITGC ▶ Configuration vs Policies ▸ Default accounts ▸ Passwords ▸ Inactivity ▸ Failed logins ▸ Time out settings ▶ Security ▸ Firewall configuration settings/changes 18

  19. Application Controls ▶ Password settings ▶ Account settings ▶ Time out settings ▶ User access reports (compare time periods) Compare all of the above with policies and procedures 19

  20. Applications ▶ Active Directory ▶ UNIX ▶ Mainframe ▶ Oracle ▶ Other Databases ▶ HRMS 20

  21. Security Incident & Event Monitoring ▶ SIEM tools in IT ▶ Great at collecting information & analyzing information ▶ Misconfigured SIEM tools. ▸ Tools are only as good as how they’re configured ▶ SIEM tools normally configured for: ▸ Excessive login attempts ▶ Privileged escalation missed ▸ cross reference with authorization data 21

  22. Data Analytics for Cybersecurity

  23. Analytics and Cybersecurity ▶ Measure IT Risk across the organization ▶ Data is very disparate and complex ▸ Big data – variable, volume, velocity ▶ Data can be very big – Log files events ▶ Use data analytics to normalize, harmonize, structure data 23

  24. Data to collect ▶ Installed application – what applications are users installing? ▶ Virus / Trojan data should be captured ▶ What systems / applications do users have access to? (IAM) ▶ IT Infrastructure ▸ servers, workstations, applications, etc. 24

  25. Data to Monitor ▶ Monitor what is being browsed on the internet ▸ Help identify sites being visited that can cause virus infections ▶ Gather information on virus infections that occur – when, where, how ▸ Is training required in certain departments or sites ▶ Is your Intellectual Property being leaked? ▸ What sites, by who, how much data? ▸ Shut down code sites like (Github) 25

  26. Data analytics monitoring ▶ Identify, quantify, rank, and prioritize your risk ▶ Develop Risk scores ▸ Uses risk scores to identify the norm so the abnormal jumps out ▶ Employees in similar departments / roles are normally the same ▸ Figuring out their patterns or behaviors is important ▸ Collecting this data can help identify the internal hackers, negligent users and opportunities to mitigate RISK ▶ Internal hackers will eventually give themselves away. Just need to make sure we are watching / monitoring the correct data 26

  27. Proactive Security monitoring

  28. DA Tools for IT ▶ Standard data analytic tools ▸ Alteryx, ACL, Arbutus, IDEA ▶ PowerShell ▸ Scripts to access Active Directory ▸ Run through EXECUTE & RUN commands ▸ Creates CSV (or other formats) files to import into above tools ▶ Forensic Software for data examination (emails) ▶ Cyber Security tools 28

  29. Proactive Security Monitoring ▶ Login Velocity – logging into multiple assets from a single source ▶ Previously Unseen Origin – Remote logging in from a location not previously seen ▶ Previously Unseen Process – Identify a previously unseen process running on critical machines ▶ Impossible Traveler – logging in from different locations that can not be achieved through normal travel means ▶ Cross User Login – same user account being logged on to multiple assets at the same time 29

  30. Proactive Security Monitoring con’t • Non-Badged User Login – identifying when an on-site login does not have a corresponding badge entry into the building • Proxy Beaconing – looking for machines reaching out to uncommon domains and IP’s • Timewheel – identifying machines performing beaconing during hours of the day when the user or system isn’t typically active. • Snowflake – analysis to find process/software that has not been seen in the environment before, across the fleet • Concerning Connections – assess network data to automatically generate network maps from which undesired, or unexpected, connections can be identified. 30
