Abstract: An intrusion detection device includes a connection interface and a processor. The processor is configured to obtain a network protocol data and an industrial operation data of each of the plurality of first packets; tag a first internet protocol (IP) address of the network protocol data with a first action role and tag a second internet protocol (IP) address of the network protocol data with a second action role respectively; obtain a related group of the first IP address, wherein the related group comprises a first industrial device information and a second industrial device information; and generate a rule list, wherein the rule list comprises the first action role, the first IP address, the second IP address, and contents of the related group, which the first action role on the rule list corresponds to the first industrial device information and the second industrial device information.

Abstract: A system and method for identifying application layer behavior are disclosed. In order to detect intrusion into an industrial control system, the system and method determine a current status of application layer behavior of the industrial control system by analyzing a current packet which is propagated between a master device and a slave device in the industrial control system, and identify whether the current status of the application layer behavior is normal according to a normal behavior status list.

Abstract: A cosmetic composition containing fragments of bacterial cellulose film is provided. The addition of the fragments of bacterial cellulose film in a cosmetic composition not only improves the transdermal transmission of active ingredients contained in the cosmetic composition but also provides the functions of skin moisturization, skin exfoliation and sebum absorption. Various applications of bacterial cellulose film are thus provided.

Abstract: A bacterial cellulose film is provided, including microbial fibers consisting of bacterial cellulose, wherein the microbial fibers are arranged in a density gradient in a direction of the bacterial cellulose film thickness.

Abstract: A touch control pen assembly comprises a pen head including a touch head and the base; the touch head being placed in the base; one end of the touch head having a spring; a rear end of the touch head being formed with an annular groove for receiving the spring so as to form as the pen head; when the touch head being pressed downwards, the spring providing a buffer force to the touch head; and a pen shaft assembly connected to a rear end of the pen head for extending a length of the pen head so that a user can hold the pen conveniently. The pen head is detachable to be used with pen shaft assembly of different types. The spring at one end of the touch head will provides a buffer force for a pressed touch head so that the pen has uniform pointing forces.
