  6. 6. ICS Security….. March6
  7. 7. The Four Horsemen of the Apocalypse are described in the Book of Revelation. The four riders are seen as symbolizing & represent the following powers: -  War -  Famine -  Death -  Pestilence
  8. 8. Horseman #1:
  9. 9. War: IT departments Corporate IT Production IT
  10. 10. War: Last 6 months.. Position Country 1 KSA 2 Iran 3 Egypt 4 UAE 5 Turkey Vertical Government Oil & Gas Financials Telco ISP Attack Types DDoS SQL injection Defacements Targeted malware Account Hijacking
  11. 11. Horseman #2:
  12. 12. Famine: Priorities ICS/SCADA perspective Availability Integrity Confidentiality IT perspective Confidentiality Integrity Availability
  13. 13. Famine: Incident Response v Handling incidents in an ICS environment is different v Forensics could be challenging v Where’s the evidence-data v Different OS & applications than corporate
  14. 14. Famine: People & Education v Lack of skilled, experienced and passionate people v  Not a lot of good education around v Only a few good books out there
  15. 15. Famine: sigh….. Some still don’t get it, So for once and for all: BASE64 is NOT encryption!
  16. 16. Horseman #3:
  17. 17. An Intel company
  18. 18. An Intel company Your ICS vendor We s..ck The MS09-XX patch cannot be applied for the next two years on our product…. Kind regards, your ICS vendor
  19. 19. Horseman # 4:
  20. 20. Easiness of attack: SCADA networks are attached to the corporate network or Internet. Exploiting of the systems is becoming easy… Background & S7 example: project IRAM – http://www.scadacs.org
  21. 21. Researchers focus more on exploits Still many firmware updates contain username & pwd in cleartext….
  22. 22. Don’t give up!!!
  23. 23. Initiatives v Many ICS vendors nowadays have a dedicated security team and are addressing vulnerabilities v Security vendors are partnering with ICS vendors to certify their products for the platforms used
  24. 24. How is McAfee contributing? EndpointNetworkData Corporate IT SCADA Device Network Enterprise Apps Ethernet, TCP/IP Modern Computers (Windows, Linux, Mac) SCADA, HMI Ethernet, Serial Legacy Computers (Windows) Ladder Logic Ethernet, Serial, Relays Special Function (Embedded OS)
  25. 25. McAfee is working with all major SCADA & ICS vendors to test, certify, and in many cases embed McAfee technology
  26. 26. Product Acceptance & Certification Currently Supported Products Cert’d OEM Integrity Control, Embedded Control, Device Control, HIPS, VirusScan Enterprise, AntiSpyware Enterprise, ePO, Roque System Detection, McAfee Agent Integrity Control, Embedded Control, Device Control Embedded Control, Device Control, HIPS, ePO, Enterprise Security Manager, IPS Integrity Control, Embedded Control, Device Control, HIPS, VirusScan Enterprise, AntiSpyware Enterprise, ePO, Rogue System Detection, McAfee Agent VirusScan Enterprise, Embedded Control ✔ ✔ ✔ OEM✔ Enterprise Security Manager, IPS VirusScan Enterprise, Embedded Control ✔ OEM✔ OEM✔ Process Management Vendor In October 2013, McAfee announced partnership with Yokogawa
  27. 27. Final thoughts….. •  What is your outside footprint? •  Do you know your critical assets? (they are not equal to a server or single system) •  Who’s responsible for what? •  When was your last assessment? •  Be realistic and agree on what risk is accepted •  What metrics do you use?
