Industrial automation and control systems have evolved significantly over recent decades thanks to many technological advances and breakthroughs. At the heart of these advances are specialized IT systems. To provide end-users with comprehensive real-time information and allow for higher levels of reliability and control, these systems have become more and more interconnected. New generation automation systems utilize open standards like TCP/IP and various web service technologies. This has brought substantial benefits in the form of improved information flow and efficiency; but it has also exposed these systems to the possibility of attack from viruses, hackers and terrorists. It’s important to maintain a secure and reliable control environment while expending minimal time and effort. Security has become a major concern for Industrial Control Systems. For Manufacturing and Control Systems in particular, the potential impact of a security incident includes endangerment of public or employee safety, loss of production, violation of regulatory requirements, harm to the environment, and equipment damage. Implementing and maintaining a secure system is a challenging mission further complicated by the use of common industrial standards, technology advances, and the need for enterprise-wide connectivity to business systems.
The solution
There is no single security solution or technology that fits the needs of all organizations and applications. Similar to process and safety improvements, security needs to be a continuous activity, involving people and organizations as well as technical solutions. While the reality is that no security can be 100% effective, careful planning and implementation of security measures, based on a systematic risk assessment, can bring security to a level that is adequate for any particular application and installation. Raybod fanavar experts team has the ability to implement various solutions with access to the solutions provided by different systems integrators that includes provides support and service for control system security throughout the complete life cycle, from installation and deployment via operation to maintenance. This includes advanced user access control and protection of computers and networks, as well as functions for secure installation, backup and restore, and for keeping the system up to date with relevant security patches.
Security measures are all about protecting the system from being compromised by deliberate or accidental attacks. Processes need to be up and running without disturbance and in a way that does not endanger people or equipment. There are three important pillars for peace of mind in regard to cyber security.

Integrity
The system’s functions and data must be protected from being modified by unauthorized persons or systems. For industrial control systems this especially relates to functions and data that directly or indirectly affect the process, such as control programs, product recipes, sensor values, or control commands. Loss of integrity of these can cause production loss and in worst case physical harm.
Availability
Unauthorized users must be prevented from denying legitimate access to or use of the system’s functions, e.g. by overloading them or causing them to crash. For industrial control systems this particularly relates to functions that are directly or indirectly involved in the control of the process, such as controllers and field I/O, but also the operators’ ability to monitor and control the process. Loss of availability of these functions may cause production loss and possibly also physical harm.
Confidentiality
Certain information needs to be protected from being disclosed to unauthorized persons or systems. For industrial control systems this mainly concerns information such as product recipes and plant performance and production data, which may represent valuable intellectual property and business assets. Loss of confidentiality for these types of information may cause significant financial losses. Also the secrets of the security mechanisms themselves, such as passwords and encryption keys, must be protected – if these are revealed the system is unprotected against many attacks.
