The integration of two industries and smart manufacturing are changing the traditional development path of the petrochemical and chemical industries. However, things are always two-sided. As chemical companies march toward information, networking, and intelligence, cyber viruses, hacking attacks, and Advanced Persistent Threats (APT) have also come.
Last week, Sun Yixuan, president of Beijing Yan En Network Technology Co., Ltd. admitted frankly in an exclusive interview with the China Chemical News reporter: “If the industrial control systems of the petrochemical and chemical industries lack the necessary safety barriers, industrial intelligent manufacturing can only be a castle in the air. â€
Reporter: As an expert in network information security, how do you view the current cyber security situation in the industrial control systems of the petrochemical and chemical industries?
Sun Yijun: The situation is very serious! Last year, there were numerous industrial infrastructure network security incidents in various countries in the world, and the safety of industrial control systems had changed from quantitative to qualitative change. In 2015, it became a turning point in the security situation of industrial control. Attacking critical infrastructure with advanced network technology has become a new form and a new tool for offensive and defensive confrontation and terrorism threats among nations. Among them, the oil, petrochemical, chemical, energy and other industries face a more severe situation due to the high-risk characteristics of their products.
The petrochemical and chemical industries are industries with a high degree of industrial control systems. At the same time, they require high stability and control strategy complexity. Once an industrial control system fails, it will not only cause huge economic losses and casualties, but also affect national energy. Security and social stability. Therefore, the petrochemical industry must attach great importance to network security at the control level.
In fact, the danger is on our side, but we do not realize it. Recently, an oil refinery in China was attacked by APT. The virus continuously searched for refinery industrial network data, illegally obtained corporate network structure information, and realized recurrence in the background, which buried great security risks for the refinery's industrial system.
Reporter: After hearing this, we understand the seriousness of the problem. Is it possible to protect the system security by installing some anti-virus software and firewalls?
Sun Yijun: Many people have this idea. However, things are by no means simple. Industrial control systems have their own characteristics, and there are also difficulties in the implementation of safety and protection measures. The simple distortion of traditional Internet security products cannot meet the requirements of network security of industrial control systems.
The cyber threats of industrial control systems in petrochemical and chemical industries mainly come from the following aspects.
First, the industrial system did not consider the network function at the beginning of the design. There are many loopholes in the industrial equipment itself. The second is that there are a large number of back doors in the industrial control system and it is easy to be used maliciously. Third, the harmfulness of the APT vicious attack is increasing. It is different from the traditional information system. Through infiltrating, controlling, and obtaining enterprise information, the industrial control system is replicated in the background so as to attack more effectively. At present, a black industrial chain has been formed in the world, and the price of each attack scenario is very high.
In addition to these three threats, there are two kinds of threats that are worth noticing. First, the threat posed by industrial viruses. First, wireless network applications make attack interfaces increasingly uncontrollable.
To solve these problems, the network security of industrial control systems in the petrochemical and chemical industries urgently requires some special solutions. Many special technologies and new technologies need to be applied instead of simply killing viruses and adding industrial firewalls. Conversely, the more devices that are added, the more failures and the more problems there are.
Reporter: You talked about so many threats and difficulties. Are there any reliable solutions to help petrochemical companies to resist the risks of cybersecurity?
Sun Yijun: There are many specific defensive measures, but the key is to increase the degree of attention in terms of ideology and understanding, establish the three-dimensional concept of industrial control network security, and build a complete security service industry chain.
In safety product development, we have also gone through some detours. In fact, blindly adding protective equipment is not the best way. The key is to establish a full-life-cycle safety protection system and provide customers with timely technical support.
Therefore, we proposed a three-dimensional security concept, including four aspects: structural security, ontological security, behavioral security, and genetic security. Structural safety is very important. If the structural safety is not solved, it is very difficult to add protection in the later period. The construction of petroleum and petrochemical enterprises is malleable. The network structure is complex and the challenges are very large. Ontology security refers to the vulnerability detection, analysis and protection of industrial control equipment itself. Behavioral safety is the addition of equipment to industrial control systems for real-time monitoring; genetic safety emphasizes the need to implant safety genes as early as possible, and network security issues must be considered during the design phase of the equipment.
Do a good job in these four areas, we must also pay attention to continuity. Security in industrial control is not a problem, but all acts of attacking and destroying industrial systems are very patience. In terms of methodology, we must ensure the sustainability of defense.
