The Ministry of National Security released a security advisory article today, stating that technology exhibitions are not only a golden stage for enterprises to explore markets and cooperate for transactions, but also a "super showcase" for cutting-edge technologies from various countries. However, behind the exhibition booth that gathers a large number of cutting-edge technologies, secret thieves silently approach, and a covert battle related to national security is quietly unfolding. Beware of exceeding the scope of "observation". Various technology exhibitions usually impose corresponding restrictions on personnel entry, photography, visits, etc., and do a good job of protection and confidentiality by posting warning signs and equipping security personnel. Especially for some high-tech equipment and military technology equipment exhibitions, there are strict security measures. However, some attendees disregarded the rules and even climbed over the "no entry" fence to collect equipment information at close range, touching the equipment with their hands, which posed a risk of leakage to exhibiting companies. There is a public case showing that at an international military equipment defense exhibition, a man ignored the warning of "no crossing" and scanned a new type of weapon with a professional device. After inspection by security personnel, it was found that the scanning instrument used by the man could identify and collect key structural data of the equipment within minutes, and remotely transmit the data, which had already exceeded the normal scope of photography. Be wary of overly intimate "contact" technology exhibitions. Some companies may choose to bring core components or the latest technologies to the venue to showcase their latest research results, allowing visitors to "feast their eyes" or even experience them firsthand. But people with ulterior motives may intentionally "scrape" the materials of exhibits for analysis through contact, in order to steal relevant material information. If the value of the target object is extremely high, some may even steal or seize exhibition equipment to obtain first-hand information. There are public cases showing that a high-tech enterprise showcased its latest developed chip at an event, but the chip sample disappeared without a trace. Although it is only an engineering sample, its architecture design still has high commercial value. Be careful of exceptionally enthusiastic "consultations" during the technology exhibition consultation process. Some individuals and organizations with ulterior motives may collect sensitive equipment information of participating companies and units in a "jigsaw puzzle" manner under the guise of data collection, cooperation inquiries, and agent negotiations. By aggregating and integrating a large amount of seemingly "fragmented" and "irrelevant" data, we can reverse engineer and refine the desired "design blueprint". Such theft can often lower the vigilance of exhibiting companies through multi-dimensional and multi-channel consultation. There are public cases showing that some individuals used academic exchanges as an opportunity to frequently visit classified academic seminar sites during exhibitions. They also collected scattered fragments of information by requesting activity materials, collecting lists of attendees, and recording speeches of on-site personnel, and provided them to overseas spy intelligence agencies for analysis and integration to form strategic intelligence. The technology exhibition not only provides a good platform for enterprises, but also puts forward requirements for the confidentiality of product achievements. While we open our arms and welcome our partners, we must also safeguard the innovative achievements we have worked hard for and the safety bottom line that cannot be compromised, so that the exhibition can truly become a safe, prosperous, and win-win stage. ——Good person management: For "viewers" who show extraordinary interest, repeatedly inquire about technical details, or attempt to touch non display devices up close, they can actively intervene and politely guide. For those who request internal information under the guise of "academic research", we should be vigilant, adhere to the approval process, and not provide information beyond the scope of confidentiality. ——Highlight: Display prototypes and models that can explore "technical isolation" solutions, such as enclosing key components with shells, fuzzifying core parameters, and using performance degraded demonstration versions. ——Keep confidential: Discarded materials and documents should be destroyed and cleaned up in a timely manner to avoid scattering and loss. Communication among staff should also pay attention to the occasion and avoid discussing sensitive information about enterprises, equipment, etc. in public areas such as restaurants and corridors.
