The invention provides a big self-supporting combined steel formwork and relates to the technical field of building formworks. The big self-supporting combined steel formwork comprises a portal supporting frame, a right-hand thread adjustment lead screw, a left-hand thread adjustment lead screw and formwork connectors. The portal supporting frame comprises portal frame structures composed of first supports and second supports, and the portal frame structures are connected through reinforcing supports. An operation platform is arranged on the second support at the topmost end of each section of the portal supporting frame. The big self-supporting combined steel formwork further comprises double-hook connectors and a firewall coping mold, wherein adjacent building formworks are connected through the double-hook connectors, and the firewall coping mold is mounted at the top of the building formwork. The invention further provides a construction method for constructing a bare concrete firewall through the big self-supporting combined steel formwork. By the adoption of the construction method, the problems of inclining, slab staggering, mortar leakage and the like caused after building formworks are assembled in the prior art can be solved; the construction speed is high, and mounting is convenient; and operation for field assembly of the steel formwork is easy, the degree of mechanization is high, and the construction cycle is short.

A network attack decoy environment construction method based on a system simulator comprises a firewall, an intrusion detection module, a signal detection module, a port redirection module, a virtualenvironment module and a data capture system. The firewall is in communication connection with the signal detection module and the intrusion detection module. The signal detection module is used for communication detection of the port redirection module and the intrusion detection module. The signal detection module is in control connection with the virtual environment module. The data capture system is in communication connection with the virtual environment module. The port redirection module is used for receiving the information sent by the intrusion detection module. According to the method, instruction plug-in mounting and monitoring can be carried out on an upper-layer real Guest operating system; the extended dynamic taint analysis technology is used for tracking network data received at the running moment, identifying illegal use of the network data and detecting network penetration attacks, so that automatic attack feature extraction is supported, a complete real operating system and an upper-layer application program are used for construction of a spoofing environment, and the interaction degree is high.

The invention relates to a detachable type cable bridge firewall and a manufacturing method. The detachable type cable bridge firewall comprises a wall body, multiple cable bridges, fireproof drawersand a fireproof sliding plate. The multiple cable bridges are arranged in a layered manner. The cable bridges are arranged on the wall in a penetrating manner and stretch out of the wall. The wall comprises a detachable first side wall, and the plane where the first side wall is located is parallel to the length direction of the cable bridges. An outlet and inlet opening is formed in the wall, andthe first side wall is used for sealing the outlet and inlet opening. The fireproof drawers are arranged in the wall and are arranged on the cable bridges. The fireproof drawers are pulled out from the outlet and inlet opening and enter the wall from the outlet and inlet opening. The wall and the fireproof drawers are used for placing fireproof bags. The fireproof sliding plate is arranged between the cable bridges and the fireproof drawers. The firewall is convenient to demount, the construction time is better shortened, and damage to the firewall due to improper operation is effectively avoided. The manufacturing method of the firewall is simple, operation is easy, the firewall demounting cost is reduced, and the efficiency for demounting and mounting the firewall is improved.

The invention provides a construction method of a gateway firewall combining software and hardware and a network protection method thereof. The construction method includes: obtaining a user's gateway firewall creation request; determining a gateway firewall node according to the gateway firewall creation request; installing a smart gateway on the gateway firewall node network card, and enable the gateway firewall offload function of the smart network card; decompose the gateway firewall to be created into the firewall of the data link layer and the network layer, and the firewall of the transport layer and the network layer above; uninstall the firewall of the data link layer and the network layer To the intelligent network card, and create a firewall at the transport layer and above in the user space, and generate a gateway firewall that combines software and hardware. Based on the software gateway firewall, the present invention provides a high-performance and stable software and hardware combination gateway firewall service for the cloud environment by combining the software gateway firewall with the unloading technology of the smart network card. cost.

The invention discloses a cable trench fireproof sealing system, which comprises a compressed air foam generating device, which includes a compressed air tank, a foam liquid tank, a water tank, and a mixer; an air inlet and a foam outlet are arranged on the foam liquid tank; Set the foam liquid inlet and the mixed liquid outlet; set the mixed liquid inlet, air inlet, and liquid outlet on the mixer; set a tee at the outlet of the compressed air tank, and the first end of the tee is connected to the air inlet of the foam liquid tank. The foam outlet of the liquid tank is connected to the foam liquid inlet, and the mixed liquid outlet is connected to the mixed liquid inlet; the second end of the tee is connected to the air inlet of the mixer; it also includes the main delivery pipe, the liquid outlet leads to the main delivery pipe, and the main delivery pipe The pipe is connected with several partition conveying pipes; nozzles are arranged on both sides of the firewall of the cable trench, and the partition conveying pipes lead to the nozzles. The invention has the advantages of high blocking efficiency, small volume, large foam output, simple construction and maintenance, safe use, and convenient mass promotion and use.
