1 Industrial Control System Cyber Security Disaster Recovery Information Exchange Bruce Tyson June 28, 2017 Lunch and Learn

2 Introduction Bruce Tyson is a certified engineering technologist (CET Telecommunications ) and a professional project manager (PMP) with over 30 years experience in the energy sector. Bruce is the President and CEO of KZenEdge Strategic Program Execution. He and his partner Tim Ewasiuk (VP and COO) operate a management consulting firm delivering solutions that span operations, engineering, maintenance and IT processes. Disaster Recovery, Cyber Security, and Industrial Controls have all been components of successful program and project delivery. For more information, visit: 2

3 Agenda Cybersecurity Risk For Industrial Control Systems Impacting Disaster Recovery Review the baseline ICS environment and key business drivers Review the cybersecurity threat landscape and a few real world case studies Review some frameworks and key resource/stakeholders for addressing ICS Cybersecurity RISK Evaluate the question, Does your current DRP incorporate the threats, priorities, standards and regulations for ICS Cyber scenarios?

6 Definitions Cybersecurity The body of technologies, processes and practices designed to protect networks, computers, programs and data from attack, damage or unauthorized access. (WhatIs) Encompasses a broad range of practices, tools and concepts related closely to those of information and operational technology security. (Gartner) Industrial Control System (ICS) Term encompassing several types of control systems technology and associated instrumentation including SCADA, DCS, and PLC s often found in the industrial sector and critical infrastructures.

7 The Issue Business Driver - Safe and Secure Operations Cybersecurity is a component of Safe and Secure Operations needs fit for purpose solutions that match their expectations for ICS integrity Clarity on organizational responsibilities Visibility to board level What is the cybersecurity posture? Plan? 7

8 Cybersecurity Priorities Information Technology (IT/IS) Confidential personal information Business Continuity Operational Technology (OT/Ops) Safety & Environment Production (Continuity) Data Integrity Confidential company info Reputation Regulatory Compliance Data Integrity Confidential company data Reputation Regulatory Compliance IT Note - Very dependent on the type of business OT Note Typical for many types of ICS environments 8

11 Examples of Access Points and the Resultant Security Challenges 11

12 Real World Threat Examples June 24, 2017 UK Parliament s November 2016 PoisonTap physical access compromise October million user accounts (confidentiality/blackmail) October 21, Distributed Denial of Service (Access/performance) October 11, 2016 Multiple Pipeline Valve Closures (safety, production, reputation) March Georgia Pacific Disgruntled Employee Cyber Attack (production, reputation) January Critical Infrastructure Incidents Increased in 2015: ICS- CERT December 23, Ukraine Power Grid ICS CERT Alerts (safety, production, reputation) Top 10 Security Breaches of 2015 (all) Dragonfly Attacks on Energy Companies (all) 12

13 Real World Threat Case Study October 21, Distributed Denial of Service (Access/performance) Scientific American Publication (abridged) Last week s distributed denial of service (DDoS) attacks in which tens of millions of hacked devices were exploited to jam and take down internet computer servers is an ominous sign for the Internet of Things. Dyn Statement (abridged) Dyn s operations and security teams initiated our mitigation and customer communications process through our incident management system. We practice and prepare for scenarios like this on a regular basis, and we run constantly evolving playbooks and work with mitigation partners to address scenarios like these. 13

14 Real World Threat Case Study December 23, Ukraine Power Grid Impact (excerpt) Power substations taken offline leaving more than 230,000 residents in the dark. Backup power at two of the three distribution centers were also taken offline leaving operators in the dark. The power wasn t out long in Ukraine: just one to six hours for all the areas hit. But more than two months after the attack, the control centers are still not fully operational. Details from extensive investigation (excerpt) they were skilled and stealthy strategists who carefully planned their assault over many months, first doing reconnaissance to study the networks and siphon operator credentials, then launching a synchronized assault 14

16 Risk Management 16

17 Risk Management Mitigation DR/ER does not influence probability it reduces impact 17

18 Incident Response Plan Have cybersecurity event scenarios been evaluated (Risked?) When does it become an explicit part of DRP? An incident is an event that could lead to loss of, or disruption to, an organization's operations, services or functions. If not managed an incident can escalate into an emergency, crisis or a disaster. Incident management is therefore the process of limiting the potential disruption caused by such an event, followed by a return to business as usual. Without effective incident management an incident can rapidly disrupt business operations, information security, IT systems, employees or customers and other vital business functions. 18
