About the system and 16 1 port

MAS is the abbreviation of mobile proxy server, and it is an access tool to assist the original business system of enterprises to realize wireless applications. After MAS access, the original business system of the enterprise can easily realize wireless applications, such as OA system, which can realize mobile phone office, email notification, mobile phone approval and so on. Composition and function of mobile agent server 1 and MAS system: MAS system includes MAS terminal, MAS server and MAS management platform. China Mobile provides information application services based on mobile terminals (including SMS, MMS, GPRS, WAP, mobile phone client, etc.). ) For group customers, by deploying mobile proxy servers in group customers (mainly government users and enterprises with complete enterprise information systems). Through the mobile proxy server, the applications and services of users in different industries are extended to mobile terminals. Composition and function of 1. 1 MAS server: Composition of MAS server: MAS server consists of application access adaptation plug-in module, service scheduling module, mobile security access module and management module. Functions completed by each component: using the plug-in module of access adapter to realize the mobile application interface of mobile application services, and completing mobile application services such as mobile office, mobile mail, on-site data query, collection, entry and WAP application through various mobile communication methods. The service processing module processes the data information received from the application system, and its main functions include information processing and routing, user authentication, service scheduling, log processing and QoS control. On the one hand, mobile security access module realizes data communication between MAS server and industrial gateway through the interface protocol provided by mobile industrial gateway. On the other hand, security encryption technology is adopted to provide functions such as SMS security access, MMS security access, GPRS security access, WAP security access, USSD security access, and smart terminal security access. In this way, the encrypted transmission of information in the air is realized, providing security services for MAS terminals. The management module completes the self-management and service of the MAS server, and can provide interface submodules including network management and authentication. You can choose business navigation, routing management, business management, data management, application publishing, statistical analysis, address book management, system configuration management and other functional modules. 1.2. MAS management platform: The MAS management platform runs in the mobile company and communicates with the MAS server through an encrypted IP channel to complete the management and control of the MAS server. The specific management contents include configuration management, authentication management, monitoring management, fault management, safety management and upgrade maintenance management. 1, 3. MAS terminal: The mobile terminal can access the application data in the information network through mobile communication methods such as SMS/MMS short message and GPRS through the MAS system to complete the data mobile application. The MAS terminal is equipped with a hardware encryption module (such as a mobile phone with a secure SIM card and a notebook with a secure PCMCIA card) to decrypt the distributed information encrypted by the mobile security access module and encrypt the uplink information to ensure the transmission safety of the received information or the sent information. The mass terminal can be a common mobile phone, a smart phone, a PDA mobile phone, a mobile notebook computer and other mobile terminals. 2.MAS system structure: 2. 1 system structure diagram: 2.2 MAS network structure: MAS server: deployed in industry users and enterprises, communicating with industry gateways and MAS management platforms through wide area networks or mobile public networks. MAS management platform: deployed in the mobile computer room, communicating with BOSS and provincial integrated network management through China Mobile's internal network, and managing various MAS servers through WAN. MAS terminal: MAS terminal uses the services provided by MAS system through mobile network. Client software may need to be installed as needed. 3. Services completed by MAS: 3. 1 MAS service description: MAS terminal forwards the service request of MAS terminal through data services such as secure short message, GPRS online mode, IP online service and WAP, and completes mobile applications such as data query, collection and entry. After the service is processed, the processing result from the MAS server is received and returned to the MAS terminal. 3.2 MAS business completion process: 1) Deploy MAS server: Install and deploy MAS server according to the business that industry users need to complete. 2) service acceptance: service acceptance sequence: 3)MAS server registration: MAS server registration management: 4)MAS server authentication and authentication: MAS server authentication and authentication 5) application access adaptation module configuration: configure plug-ins to be opened in the mobile application access adaptation module in the MAS server, including basic information of the MAS server, including host information, number of supported users, IP address, service port, etc. 6) Running the MAS system: the MAS server opens corresponding functions according to the mobile data service and service adaptation ability issued by the MAS management platform; The MAS management platform monitors and manages the equipment status and running status of the MAS server; The MAS terminal is equipped with a security module and an application module to realize secure communication between the mobile communication network and the MAS server. As a service proxy server, the MAS server forwards the service request of the MAS terminal to the application service processing server, receives the processing result from the MAS processing server after the service processing is completed, and returns the processing result to the MAS terminal. 4. Security in MAS system: MAS system adopts security measures to ensure the security of information network transmission, MAS server, industry user information network and mobile terminal, and to protect the overall security of mobile applications of users in China mobile industry. 4. 1 data transmission security: the MAS server connects the industrial gateway and the MAS management platform through VPDN to ensure the security of data transmission from the IP link; Information is transmitted in an encrypted way in network transmission, which ensures the security of data transmission. In industries and applications that require high security transmission, a special security transmission and authentication system with higher security level can be used to ensure information security. 4.2 Mobile terminal security: Special security SIM card and security PCMCIA module can be used for information encryption and user identity authentication on the mobile terminal to ensure the security of the mobile terminal. 4.3 Security of MAS management platform: MAS system provides security functions from a series of aspects, such as access control, security detection, attack monitoring and operation audit, and has complete network security monitoring, alarm and fault handling functions, thus ensuring the security of MAS management platform. 4.4 Perfect authority management and log management: MAS system provides perfect management logs for database logs and operating system logs; The security SIM card/security PIMCIA card on the mobile terminal and the authority management of users and administrators provided by the MAS management platform effectively manage the access rights of the MAS system. 16 1 port: 16 1 port is used for Simple Network Management Protocol (SNMP). Port Description: Port 16 1 is used for Simple Network Management Protocol (SNMP), which is mainly used to manage network protocols in TCP/IP networks. In Windows, SNMP service can provide status information of hosts and various network devices on TCP/IP network. At present, almost all network equipment manufacturers support SNMP. To install SNMP service in Windows 2000/XP, we can first open the Windows Component Wizard, select management and monitoring tools in the component, click Details to view Simple Network Management Protocol (SNMP), and then select this component. Then, click Next to install. Port vulnerability: Because the status information of various devices in the network can be obtained through SNMP, it can also be used to control network devices, so hackers can completely control the network through SNMP vulnerability. Operation suggestion: It is recommended to close this port.
