Industrial Control Systems (ICS) is mainly used to control energy, transportation, water conservancy, petroleum and other important infrastructure closely related to people's livelihood, so the safety of its system is very important. In general, ICS must be in working condition at all times, so it is often extremely difficult and expensive to securely harden or upgrade these systems.
The output of ICS is related to physical processes and has a major impact on people's lives. Any system failure or failure can cause unpredictable losses, such as large-scale energy supply disruption. Therefore, the organization that manages ICS can't risk the system failure to let ICS automatically upgrade or harden the security system to avoid loss due to ICS shutdown or restart. For example, a typical operating cycle for a nuclear reactor is 18 months, and any system failure can result in huge economic losses.
Franky Thrasher, information security manager at Belgian Power, said that the above reasons make it difficult to decide whether the system should be taken offline to upgrade the security system. He said at the Information Security Solutions Conference in Brussels: "The security protection of ICS requires not only network security, but also the introduction of entirely new mechanisms." Typically, even organizations responsible for managing critical infrastructure have detected control systems. Invaded by malware, they will still keep the system running.
For many ICS, only 5 minutes of downtime is allowed per year, which is extremely difficult to obtain legal evidence to investigate potential security breaches or malware intrusions. More seriously, the general ICS runs on a small processor, and its computing power is very limited, so it is impossible to install anti-virus software on many ICS.
Keep ICS secure on legacy systemsMany European and American ICS have been running for 15 to 30 years, and such systems are more difficult to maintain. These systems were installed before the Internet era, so they were not designed with connectivity in mind and there were no measures to verify that the received commands were correct.
Markus Braendle, ABB's network security leader, said that replacing these legacy systems is not feasible, and we need to enhance security for new and legacy systems. However, Braendle added that these legacy systems have been running without problems for decades, so it is difficult to convince these organizations to spend large sums to upgrade the system.
Save money with an unsecured operating systemAs many commercial management systems enter the market, some organizations use some management systems that do not need to be customized in order to maintain system uniformity and save costs. Such as the introduction of Microsoft's Windows and Linux operating systems, which makes the enterprise network and ICS management system establish a connection.
"This means that ICS is exposed to more threats, including operating system vulnerabilities and the risk of intrusion caused by the connection of industrial plants to the outside world," Braendle said. "While connecting ICS to an enterprise system is beneficial, the way it is connected needs Choose carefully."
Another risk of using commercial operating systems is that these organizations may not be able to upgrade their systems to the latest and most secure versions in a timely manner.
"We advise some organizations to stop using the Windows XP operating system because Microsoft is no longer supported, but they say they are still using older versions." Braendle said, "Generally, organizations are reluctant to upgrade their The system, because upgrading the system not only requires high overhead, but also needs to modify the entire system to meet industry standards.†Braendle believes that for security reasons, regulators need to make system upgrades easier.
Wider ICS connections require greater securityIn Europe, the shift in the trading of energy, like commodities, drives the need to establish a link between ICS and traders. In order to enable suppliers to remotely maintain and monitor the system, suppliers also need to establish contact. Braendle said that the actual ICS is rarely completely disconnected from the outside world because of the commercial needs of the connection.
Although the media has begun to focus on the security field of ICS, Braendle said that this topic has been discussed in the energy field for a long time. “Public attention to this topic has only recently begun, because smart meters have been introduced into personal homes, so people are beginning to worry about privacy issues. Similarly, the emergence of the computer worm Stuxnet has also made people aware of the importance of ICS security and ICS. The consequences of being attacked."
According to Thrasher, another challenge in maintaining ICS comes from the fact that IT departments and IT security teams rarely participate in the procurement, installation, and management of ICS. “ICS is generally purchased with the equipment it controls, so their installation, configuration, and operation are done on-site by the plant engineer, not the IT department. This means that IT has no knowledge of the control system and is unable to build Detailed directory of the system."
Future Bus connectors Description
Future Bus connectors, which use 2mm style have a mating distance of 10mm. Both Future bus and the upgrade Future bus+ are out-dated.No additional work has been done to upgrade the specification over the years. However we still produce products which meet the Physical and Electrical layers of IEE P896.
