6MODELING AND SIMULATION IN CYBER-RISK

LEARNING OBJECTIVES

• Describe the concept of simulation with its static and dynamic components and its relevance to cyber-risk informatics and risk engineering.
• Explore the innovative and popular theme of engineering modeling and simulation, predominantly in the manufacturing industry and cyber-security world, citing severe challenges, advantages, and time- and budget saving solutions and its future.
• Study a cross section of engineering modeling and simulation practices illustrating a window of numerical examples with relevant and useful statistical data-scientific modeling.

6.1 INTRODUCTION AND A BRIEF HISTORY TO SIMULATION

The favorable computing outcomes since the advent of digital computers and software revolution could not have been achieved, especially without the multiple benefits of statistical simulation, which underlies the widespread use of modeling and simulation in engineering and sciences, stretching from A (anthropology) to Z (zoology). Modern computer simulation developed in parallel with the rapid growth of computer use during the development of the Manhattan Project in WWII to nondestructively model and simulate the nuclear detonation before it was destructively dropped on Hiroshima and Nagasaki in Japan in 1945. Therefore, the history of simulation is interesting and intriguing. Some earliest pioneers can be observed in [1]. Lord Rayleigh in 1899 showed that a one-dimensional random walk without absorbing ...
