Communications. In ICS field devices used in the environment control and internal processor communication communication protocol and the media, usually with gm in the IT environment, may be proprietary.220v-750w電加熱管
Change management. Change management is very important to keep IT and the integrity of the control system. Not patched software for system is one of the biggest holes. Software update IT system, including security patches, usually in accordance with the corresponding security policy and procedures to update. In addition, these procedures often use server-based tool automatically. ICS software updates are not always timely implementation, because these updates need to industrial control application provider a thorough testing, then the application of the end user to implement, must also be in a few days or weeks in advance planning and arrangement of ICS downtime. As part of the update process, ICS may also need to confirm again. Another problem is that many ICS use the old version of the operating system, the supplier is no longer supported. Therefore, patch available may not be applicable. Change management can also be 220v-750w電加熱管applied to the hardware and firmware. In the process of change management, part of ICS, need ICS experts (for example, the control engineer) to work with security and IT professionals, careful evaluation.
Management support. Typical IT support system allows diversified way, because of the interconnection technology architecture, the content of the support may be completely different. Usually take for ICS, service support through a single supplier, other suppliers may not provide the diversification and interoperable solutions.220v-750w電加熱管
Component life. Typical IT component has a is about 3 to 5 years of life, as a result of rapid evolution of technology, the problem is simple. For ICS, and many technology for a particular application, deploy technology life cycle is usually for 15 to 20 years, sometimes even longer.
