(4) Strengthen safety education and publicity, and increase the safety protection concept of computer system and network for managers and users ① Do not affect openness due to strengthening safety management. ② It is not allowed to increase huge system overhead and affect network interoperability by strengthening security management. ③ Safety measures shall be easy to operate and flexible. ④ The performance price ratio shall be considered for safety measures.
2、 Daily management and maintenance
The common characteristics of intranet are that there are many computer host models and other network equipment, distributed in different regions, and the quality of basic level network management personnel is low; This requires the network administrator to establish the system equipment file. Generally, a small database can be used to complete this function. Once the equipment in a certain place fails, it is convenient for online query. The database shall generally include the following contents: equipment model, manufacturer, configuration parameters, installation time, installation location, IP address, Internet access record and contents, etc. The server and client shall also record their memory, hard disk capacity and model, terminal model and quantity, multi-user card model, operating system name, database name, etc.
(1) Manageable equipment
For some network equipment, there is generally corresponding network management software. It shall be installed in time. These software can automatically identify, display and manage the network topology. Network system node configuration and management, system fault diagnosis, display and notification, network traffic and status monitoring, statistics and analysis, network performance tuning, load balancing, etc.
(2) Non manageable equipment
For unmanageable equipment, the status shall be checked by manual operation, and regular inspection and random spot check shall be combined, so as to grasp the operation status of the network in a timely and accurate manner, and handle any fault in a timely manner.
(3) Communication practice
For internal lines, structured cabling should be used as far as possible, which can greatly reduce the network failure rate, and even if there is a failure, it is easier to eliminate it. For the leased communication line of the telecommunications department, the network administrator should make a record of the connection of the communication line. In case of failure, the network administrator should contact the telecommunications department in time to quickly restore communication.
(4) Daily management and maintenance of software
The management and maintenance of software mainly includes operating system and application software. Ensure the normal operation of the network and the safety of the system and data through software management and maintenance, and ensure the recovery of the system and data in an emergency to minimize the loss reporting.
