Windows 7: Security Features

In the operating system, security is always the most concerned and most worrying issue. As the most widely used operating system, Windows has certainly become the target of many malicious acts. Although Microsoft has taken a lot of measures, in the past versions of the Windows operating system, it still suffers from various security problems. Fortunately, most of the problems are handled in a timely manner by Microsoft. In Microsoft's new operating system, Microsoft clearly pays more attention to security issues, making the Windows 7 system's security features a new look, not only incorporating more security features, but also the original security features have been improved and enhanced. Let me take a look at the main security features of Windows 7 one by one with the seven children.

First, get rid of the "chicken ribs" name to explore the new Windows firewall

Windows Firewall is a security defense system built into the XP system to help users Protect your computer from hackers and malware. However, at the beginning of the release, Windows Firewall only provides simple, primary functions, only to protect inbound traffic, so the first thing many old birds do after installing the machine is to turn off the Windows Firewall "Chicken Ribs".

Fortunately, after experiencing the excessive Windows Vista, the firewall function in Windows 7 began to show the taste of "professional". The new Windows Firewall has many revolutionary improvements. It not only has the ability to filter outgoing information, making it more usable, but also adds support for multi-function firewall policies for mobile computers, making it more flexible and easier to use.

For the Windows 7 firewall, the seven favorite is its ease of use, you can complete all the relevant settings and adjustments through the options in the control panel, and for most ordinary users, The only action required to set up is to make a selection and click the mouse. Open the Control Panel and go to the “System and Security” category. On the right side we can see the option “ Windows Firewall”.

Entering the Windows Firewall option of the Control Panel, perhaps your Windows 7 system does not have the firewall function enabled, there will be a prompt on the interface, Qizi recommends that you open Windows Firewall to ensure Internet security. Just click “use the recommended settings" to have the Windows Firewall automatically start using the recommended settings to protect your computer.

In Windows 7, Windows Firewall divides your network into home or work networks and public networks by default. In different network situations, we can easily and easily switch configuration files and choose different levels of network protection. For example, when we are in the home network, other computers and devices are familiar to us, then the configuration file allows incoming connections, which can easily share pictures, music, videos and document libraries with each other, or share hardware. Equipment, such as printers; and if you carry this notebook to public places such as airports, coffee bars, etc., in the public network such as wireless connection, you must pay more attention to connection security, you may need to interrupt some incoming connections, now through the Windows firewall we It is easy to switch the network location to “public network” for more secure security.

For different network location configurations, we can also make some fine-tuning and opening settings. Click on the "Change Notification Settings" on the left side of the Windows Firewall interface, or "Firewall Switch", you can also enter the "Custom Settings" interface, where we can fine-tune the settings of various network locations. , such as firewall open, notification mode, block incoming connections, and so on. Windows Firewall will block connections to programs that are not on the list of allowed programs, but in general, it is recommended that you block all incoming connections on the public network to improve security, but this does not affect general web browsing and Instant messaging.

(Small Tip: How do I change my network location? In the Control Panel, select "Network & Internet>-“Network & Sharing Center" Then click on the network type area on the interface, and then select it in the pop-up "Set Network Location" window.)

If you have various settings for Windows 7 Firewall More understand, then you can click on the "Advanced Settings" on the left to enter the Advanced Security Settings console. Here, we can set up the configuration file for each network type, edit the inbound, outbound rules, etc. Of course, if you are not "old bird", you can completely ignore this advanced setting function.

In the "Allowed Programs" setting of the firewall, we can set up and manage the programs that allow communication through the firewall. You can use what you want. The programs that are added are added, giving them permission to communicate. I believe that these settings are not unfamiliar to everyone. The same is true for other third-party firewall programs. I won't say more here.

From the above we can see that Windows 7 firewall has many improvements in function and use, I believe it can bring us a real network firewall Guarantee, and no longer in the eyes of everyone, "chicken ribs". Let's take a look at the other security features of Windows 7.

Second, user-friendly hierarchical user account control trial

User Account Control (UAC) is a feature introduced in Windows Vista system, it can monitor and ask important changes to the computer Whether to permit changes to help prevent malicious programs from damaging the system. In the Vista system, UAC is as criticized as the Windows firewall, mainly because it brings a lot of operational troubles to users.
