IT personal year-end work summary

First, the daily maintenance of pmd it

Formulate the owner's camp management rules, optimize the network structure, supervise and manage all kinds of equipment, debug, maintain, repair, and handle the daily management of the owner's camp network failure; use ac online behavior management equipment to make rational use of network resources, strictly Control the behavior of the Internet; cooperate with the network provider to maintain the regional network and the external network of the owner's camp to ensure the normal operation of the network; use the operation interface and network management tools of the network equipment to implement the daily network and system monitoring of the camp and Reasonable adjustments to network and system performance, and recovery measures, including road switches, route adjustments, device configuration updates or recovery, periodic production of various reports, and improvement suggestions based on reports; prevention of network failures, and development of networks Emergency treatment after the attack; use the telephone system to properly adjust the telephone number and telephone usage, and reasonably control the camp telephone charges; the cable channel is not regularly checked, the fault is established, and the fault is established in time; the equipment room equipment is not regularly checked. Use case to reduce failure rate

ø ac online behavior management

With the popularity of the Internet access and the increase in bandwidth, the conditions for employees to access the Internet have been improved, and on the other hand, the company has brought higher risks, complexity and confusion to the use of the Internet. Pmd uses ac Internet management equipment to control employees' online behavior during work hours to strengthen employees' participation in online activities that are not related to work during working hours, make full use of resources, prevent illegal use of mail, browse illegal web sites, and conduct music during working hours. / Movies and other bt downloads or online streaming media.

This year, the most popular web authentication technology for pmd web authentication technology ac security gateway web-based user authentication function makes it easy for administrators to manage online users. After the employee has enabled web authentication, in addition to regular authentication of the client's local identity, web authentication will be enabled. When the client enters any URL in the browser, the ac security gateway asks the user to enter a username and password for authentication. Only when the user enters the correct account can the user access the internet. It is convenient to make reasonable use of pmd bandwidth resources.

ø it equipment to establish a ledger, timely update, regular inspection to ensure normal use;

Virus prevention must strengthen the awareness of teaching prevention, often upgrade anti-virus software, and regularly anti-virus machines.

Every quarter/month is not regularly tested on all pmd computers. After the test, fill in the "pmd computer daily maintenance table"; on-site computer - hp, ts self-configuration, etc., the use of genuine software by CLP, very important to prevent virus invasion The key is to check and maintain the computer from time to time every month to ensure the normal operation of the computer and network. For ts self-configured computers, etc., because of the installation of pirated software and illegal Internet access, the virus prevention is weak, the computer runs at a relatively slow speed, and when it is not regularly checked and maintained every month, it is carefully checked to meet the problem. Solve and deal with it to ensure normal work. If the computer is used improperly, find out the cause, remedy, and hold it accountable, so as to avoid the similar error again next time; for the employee who violates the computer management program, make a verbal warning--mail warning--written warning; for the basic application operation Do not understand, personally operate, carefully point; the unit connected to the pmd network, meet the problem, carefully resolved, in order to achieve normal operation.
