Industrial control systems form an important part of software applications which aids in facilitating the various operations in the crucial sectors of the industry. There has been a vast growth in issues with cyber security, which has negative impacts on the industrial control systems. This paper describes the direction and guidance to be used in developing and layering defense in depth strategies for the different organization using the control system networks. The different control networks should maintain a multitier information structure which requires accessing the facilities through the modem or data link. Also, access to the robust business environment requires several connections to the external internet, system domain, and other peer organizations. Across different private and public domains, there are many shared attributes that regard data communication and IT deployments in information infrastructures, for example in the control system domain. Many systems use the robust architectures in enhancing business and reducing costs where they increase the integration of business, control system networks, and the external environment. However, the integration of the multi-network strategies often brings about vulnerabilities thus reducing the organization skills and exposing mission-critical control systems to the cyber threats. Defense in Depth is an effective and efficient way of building an information security plan. It provides a framework for the organizational security needs.
