10 Agenda 9 Cyber Security - Today Cyber Security Profile Cyber Security Solutions Honeywell Risk Manager Conclusions Open Discussion

11 What is Cyber Security Profiling (CSP)? CSP is the security characterization of the ICS in a specific plant in terms of security objectives, as well as security properties. It defines the target protection characteristics and the actual implemented protection characteristics of an ICS or subsystem. 10 It provides a response to questions such as: To what extend must we protect the ICS? (Target) To what extend have we protected our ICS? (Actual) How can we reach the Target? (CSP Roadmap) Optional: How do we compare to other ICS? (Benchmark)

12 Typical security level 12 IEC Skills Motivation Means Resources SL4 Nation-state ICS Specific High Sophisticated (Campaign) Extended (multidisciplinary teams) SL3 Hacktivist, Terrorist ICS specific Moderate Sophisticated (Attack) Moderate (groups of hackers) SL2 Cyber crime, Hacker Generic Low Simple Low (Isolated individuals) SL1 Careless employee, contractor No attack skills Mistakes Nonintentional Employee, contractor
