1st, uses the firewall, lets the long-distance maintenance be safer
In shares ADSL to carry on the digit dialing accesses the net, many network administrators always like through the long-distance tabletop function coming in the long-distance management and maintenance local area network's other computers, with the aim of enhancing the network the management and the maintenance efficiency. But we knew, uses the long-distance tabletop function at will, attacks the local computer for the illegal aggressor to provide the invasion easily “the channel”, if we can try to find solution to let the Vista system protects this “the channel” the turnover security, then the network administrator will use this “the channel” to carry on the long-distance maintenance operation the security greatly to enhance. Must let the firewall protection long-distance maintenance operation the security, we may defer to the following step to carry on:
First in the Vista computer system tabletop, single-clicks “the start” one by one with the mouse, “the establishment”, “the network connections” the menu option, in after that appears in the network connections contact surface found the goal ADSL connection icon, and struck this icon right with the mouse, chose in the right key menu again “the attribute” the order, opened the user account control interface, the one-shot “continues” the button, entered to the goal connection attribute window;
Single-clicks “sharing” in this attribute window the option card, turns on option establishment page which as shown in Figure 1, “allows other network user this page to connect the project through this computer's Internet connection” to select, and single-clicks “the establishment” the button, enters to the high-level establishment contact surface;
Will establish in the contact surface “the long-distance tabletop” the option to select high-level, single-clicks again “determines” the button, the withdrawal goal network connections high-level establishment contact surface, then the network administrator in the future will use the long-distance tabletop function when carries on the management maintenance to local area network's other workstations, the security will obtain obviously guarantees.
2nd, uses the firewall, the prevention illegal Ping attack
We knew that each time when transmits the Ping order test data package to the goal main engine, the goal main engine needs to consume certain system resources to carry on the reply reply, if when some simultaneously when transmits tens of thousands of strip test data package to the goal main engine, then the goal main engine needs to consume quite many system resources to these test request to carry on the reply, after achieving the certain extent, the goal main engine's limited system resources will possibly be consumed the danger. In network many virus or the hacker will come through the above method to the goal main engine to implement the Ping order attack frequently, will thus cause the goal main engine to break down paralysis; In order to prevent illegal Ping the order attack local Vista workstation system, we may establish this system bringing ingeniously the firewall, with the aim of preventing the local workstation to come from the network the Ping order request to carry on the reply, as soon as such came to be able to avoid the Ping order attacking:
