5 Market Trends US - NERC-CIP, NIST Cyber Security Framework Regulation European Union - Directive on security of network and information systems (NIS Directive July-2016), local initiatives, etc. Applicable Utilities (Electric, Water & Sewage) Critical Manufacturing Initial phase in APAC Smart Grid IoT and Smart Cities Growing Awareness Distribution Automation Smart Metering Globally Recent attacks [Internal Use] for Check Point employees 5

6 ICS-CERT Report: United States Critical Infrastructure Increasingly Targeted The Most Targeted Sectors Integrated Threat Prevention Manufacturing, then Energy Most Common Method of Attack Spear Phishing Boundary Protection Boundary Protection was the single most common ICS weakness discovered during assessments. Effective Boundary Protection is a pillar of the cybersecurity Defensein-Depth concept. ICS-CERT: These attacks were enabled by insufficiently architected ICS networks [Internal Use] for Check Point employees 6

12 CrashOverride/Industroyer New ICS attack platform to Electric Grid Operations CrashOverride (called Industroyer as well) malware was the malware employed in the December 17th, 2016 cyberattack on the Kiev, Ukraine transmission substation which resulted in electric grid operations impact. (As reported by ESET and Dragos) ICS-CERT reported on June 14, The tactics, techniques, and procedures (TTPs) described as part of the CrashOverride malware could be modified to target U.S. critical information networks and systems. CrashOverride malware is an extensible platform that could be used to target critical infrastructure sectors, specifically using IEC104 and IEC61850 protocols. The malware issues valid commands directly to RTU s. Using Check Point protocols visibility and baselining would detect and alert on None-Baseline protocols and commands Could exploit Siemens SIPROTEC relay denial-of-service (DoS) vulnerability, leading to a shutdown of the relay. Using CVE to Hamper Protective Relays Check Point published on June 20 th an IPS signature for virtual patching protection of the DoS vulnerability [Restricted] ONLY for designated groups and individuals 12
