In addition, 4% of respondents answered that “We rarely make improvements”, which is higher than other industries. A mechanism for network segmentation, appropriate access control, and detection of anomalies in internal routes is required.ĭespite these circumstances, when asked if their organizations have improved their cybersecurity after incidents, only 43% of respondents answered that they "always/usually make improvements." Lower than the overall average of 52%, this trend is common to the US, Germany, and Japan, and Japan has a gap of 19 points from the TOP manufacturing industry.
Instead of implementing measures for IT and OT individually, measures that assume that attacks on IT (email, web) will reach ICS are necessary. This result suggests that the office terminals used in the IT area or OT area became an intrusion point. Q4_1 ~ Q4_7 How has your organization dealt with the following types of cyber attacks? (NB: Multiple choices allowed)
In addition, the vulnerability to phishing is prominent, and compared to other industries, especially compared to Electricity, there is a difference of more than 10 points. As a result, the oil & gas industry had the highest number of malware infections during web browsing, followed by "Compromise of internet accessible device". In response to a question about how they dealt with various cyberattacks, we analyzed the types of attacks that answered, "We were unable to stop this type of attack and had to respond to the incident”. １-２ Malware infection due to legitimate web browsing was the most frequently cited attack that forced the system to stop operating while dealing with cyber-attacks. In fact, the average loss amount is calculated to be about 1.8 times that of the manufacturing industry. As a result, the amount of production decreases and the loss amount increases. If processing stops midway, proper chemical synthesis will not occur and the products will have to be discarded. This takes because it requires chemical processing. The reason why the downtime is longer than in other industries is that once a process automation system is stopped, it is necessary to discard the products in the process of manufacturing and clean the production equipment. In addition, 65% of respondents said that the system stopped for more than four days, which is a very large number compared to 50% for manufacturing and 56% for electricity. It was found that the oil and gas industry averaged 6 days for system outages due to cyberattacks, one day longer than the five days for other industries.

１-４ Drivers of enhanced security are requests from partners and customers and compliance with regulations １-３ Difficult to take measures to prevent recurrence of cybersecurity improvements １-２ “Malware infection due to legitimate web browsing” was the most frequently cited attack that forced the system to stop operating while dealing with cyber-attacks. １ Characteristics and Considerations of the Oil & Gas Industry Regarding Cyberattacks There is a similar movement in Europe, and there is a lot of discussion in Japan about the next cybersecurity strategy, including the protection of critical infrastructure.
In response to this incident, the government proceeded with the development of laws one after another and established new evaluation criteria for security management systems. This six-day suspension of pipelines disrupted the lives of citizens. The IT accounting system was forced to shut down their OT system. News of the cyber attack on the US Colonial Pipeline in May 2021 has had a major impact on the oil and gas utilities industry. This time we will focus on the Oil & Gas industry. We will also introduce Trend Micro's proposals based on the current state of the industry. Based on the results of a survey of over 900 ICS business and security leaders in the United States, Germany, and Japan, we discuss the characteristics of each industry, the motivations and environmental factors that will drive future cybersecurity improvements. Trend Micro conducted a study on the state of industrial cybersecurity in the oil and gas, manufacturing, and electricity/energy industries in 2022.
