Network Security guards Rookie


With the rapid development of the network to prevent malicious hackers to focus on online network security is of growing importance. As a general Internet users, the usual practice is to install the network firewall to monitor and prevent network attacks. To meet the needs of this area there are many well-known software, such as foreign Norton, Tiny Personal Firewall and made the Skynet firewalls, security, etc. Star XP.

I recently tried Kingsoft has just launched personal network firewall - Kingsoft Internet Security 2002, although only in beta, but adhering to the Duba's style, easy to use yet feature impressive. Users can set the application's access permissions, and through the high, middle and low security level settings, to different degrees, online security and defense purposes. It can prevent such as glaciers, and other common Internet Thief Trojan on the user's damage; if Trojan invasion, Duba Online test version of personal firewall will intercept time, and pop-up dialog box tell the user has been successfully blocked, truly real-time Protect your computer security. This compact tool is very suitable for the safety of single users to anti-triad.

Installation process, Kingsoft Internet Security automatically generate a permanent lower right corner of the taskbar icon. Double-click you can see the main interface (Figure 1).



Figure 1

Kingsoft Internet Security 2002 is very simple and friendly interface, users do not understand the rules and obscure the IP network protocols, by simple operation, can easily be secure network protection. In the upper left part of a scroll bar of the window is the status information output window, in Duba Online beta is running a personal firewall, all the status information will be displayed in the window. Below the multi-grid is composed of two lines of visual display of network traffic, above the line box to indicate the number of bytes received, the next line is the number of bytes sent.

The main interface through the left most lower part of "detailed information" and "System Settings" two buttons on the right is a safe level above the Settings button, you can customize this were high, medium and low three different levels of security to protect your computer security. Right below the "off network" button, click this button, you can prevent your computer and network connection. If you click the button, then "off network" to "restore the network" you click this button restore network connections. Let's take a look at the specific functions and the corresponding button to use.

Second, the main function of the operational use

1, network firewall security level settings

Jinshan net dart according to the characteristics of users, but also to facilitate the use of primary users, the security level of classified and less in the third class, can easily right through the main interface, the "security level" slider cursor to select (Figure 2 ).



Figure 2

3 security levels, corresponding to three different sets of IP packet filtering rules. Specific rules are as follows:

"Low security level": all applications will first access the network when asked, has been approved procedures are in accordance with the rules of operation of the corresponding set. The computer will be completely trusted LAN, allowing the machine to access your internal LAN to provide the services (file, printer sharing service), but the machine against the Internet to access these services.

"Safe level": all applications will first access the network when asked, has been approved procedures are in accordance with the rules of operation of the corresponding set. Against the internal LAN and the Internet to provide machine access to your network shared services (file, printer sharing service), LAN and Internet machine will not be able to see this machine.

"High security level": High security level only allows network access commonly used (such as browsing the Web, download files, and send and receive mail, etc.), to forbid others to share resources on this machine visit. All applications will first access the network when asked, has been approved procedures are in accordance with the rules of operation of the corresponding set. Against the internal LAN and the Internet to provide machine access to your network shared services (file, printer sharing service), LAN and Internet machine will not be able to see this machine. In addition to being recognized by the program to open the port, the system will block out all the ports open to the outside.

2, for procedures for access control

Kingsoft Internet Security at the start of the case, as Kingsoft Internet Security with the application packet to the bottom of blocking features, so when the Windows system applications (such as IE, Foxmail, Tencent QQ, etc.) the operation of an access network, its communications sent and received packets will be intercepted Kingsoft Internet Security Analysis. At this time the firewall will be based on user permissions on this application to set the network processing applications for network operations, the default approach is: when the application occurs when the network operator Kingsoft Internet Security will ask to the user, the user decide whether to grant this application process rights of access to the network. Users can also network after this application permission to change the list of previous settings. Specifically, how does it work?

Click the main interface of "detailed information" button in the lower part of the pop-up window, click on the "procedural rules" button, an "application to access the network permission settings" page (Figure 3).



Figure 3

When an application needs to access the network when the first run, the window will pop up asking, and will be automatically added "applications network access permission settings" list, the list shows all the details of launching applications, including the start run time and where the path. In the application next to "Allow", "ban", "ask" the three options, respectively to allow access to the network, prohibiting access to the network, and asked whether to allow access to the network. For example, when you first open the QQ Chinese Internet pager, it will pop up a query window (shown):



Figure 4

When you click "Allow", then QQ to normal access to the network, and connect login server; if you a "ban" button, then QQ can not be connected to the network, you will not be able to go online to chat with a God! In this pop-up window, if under the "In the future operations are conducted in accordance with this," before the box was marked "√", then the default for all future operations are conducted in accordance with this operation. The QQ is the Chinese Internet pager in Figure 3 is automatically added to the "application to access the network permission settings" list.

3, to personalize the "security level" Custom

For those networks richer knowledge of the advanced users, they can develop a more personalized level of security rules. Method is the main interface, click on "System Settings" button, will pop up "System Settings" dialog box (Figure 5).

4, use good security log

Click the "Security Log" button, a "Security Log" page (shown):



Figure 7

Kingsoft Internet Security will be all the irregularities of the data packet interception and the "security log" in the record. If you choose to monitor TCP and UDP packets, that each of you to send and receive data packets will also be recorded. Each record from left to right are sending / receiving time, sending IP address, packet type, the corresponding address of the machine, the operation records and other information. Here we note that not all blocked packets are meant someone attacks you, some normal packets but probably because you set the security level is too high and not meet the safety requirements will be Kingsoft Internet Security intercept them and the police, as set against other Ping your host, then when someone sends to your host Ping command, Kingsoft Internet Security will also sent to the data block recorded in the log and down the alarm.

"Security Log" can be exported and be deleted, click on "Security Log" page at the top left of the "" button, a "Save as ... ..." dialog box, you can save your security log to make a backup. Click "" button, a "confirmation" prompt box, click "OK" button to delete your security log.

5, intelligent killing hacker program

This is the most advantageous Kingsoft Internet technology. General professional network firewall network administrators because it is designed for the face, only to do the port and packet flow report, the general users of this information prompt can not judge in the end is harmful to the normal data flow or data flow, and surface Kingsoft Internet Security 2002 on the single user, smart Hacking techniques can provide information directly, it tells the user which data packets directly to a hacker attack property, which the packet is a remote control Trojan horse property, etc.. Filtered from the ports and the definition of a hacker intercepting known viruses, Trojans, to protect your computer security. Of course, to prevent theft of your personal information.
