Windows 7: Aspects of security features

Friend, are you still sticking to XP? Are you still enduring "Vista"? Why not try Windows 7? As long as you have a taste of her superior performance, gorgeous appearance, it will certainly be for her charm to be impressed. How? You don't know about Wndows 7? Don't know how to use it? Never mind, the IT168 software group prepares you for a series of tutorials that teach you how to learn Windows 7.　　　 This tutorial is divided into basic, intermediate, advanced three parts, through this series of our lovely seven doll will teach you step-by-step to learn windows 7.





in the operating system, security has always been the most concerned about, but also the most concerned about the problem. Windows, as the most widely used operating system, is certainly a target for many malicious acts. Although Microsoft has taken a number of measures, in the past version of the Windows operating system, it still has been criticized for a variety of security issues, fortunately, most of the problems Microsoft through the patch upgrade in a timely manner to deal with. In Microsoft's new operating system, Microsoft clearly attaches more importance to security issues, making the security features of the Windows 7 system fresh, not only incorporating more security features, but also bringing improvements and enhancements to the original security features. Let me take a look at the main security features in Windows 7 with seven.





first, get rid of the name "chicken Ribs" to explore new Windows Firewall





Windows Firewall is a security defense system that has been built into the XP system to help users protect their computers from hackers and malware. But at the beginning of the release, Windows Firewall only provides simple, primary function, only to protect inbound traffic, so many veteran installed after the first thing is to shut down Windows Firewall this "chicken ribs."





the firewall feature in Windows 7 begins to show a "professional" flavor after Windows Vista is over. The new Windows Firewall has revolutionized the ability to filter outgoing information, make it more available, and increase the number of firewall policies that support mobile computers, more flexible and easier to use.





For Windows 7 firewalls, the seven most appreciated is its ease of use, through the options in the Control Panel you can complete all the relevant settings and adjustments, and for most ordinary users, set the operation is only to make a choice and click the mouse. After you open the Control Panel and go to the system and security category, on the right we can see the options for Windows firewall.





access to Control Panel Windows Firewall option, perhaps your Windows 7 system does not turn on the firewall function, in the interface will be prompted, seven people recommend Windows Firewall to protect the Internet security. Just click on "Use recommended settings" to have Windows Firewall automatically use the recommended settings to start protecting your computer.





in Windows 7, Windows Firewall defaults to dividing your network into a home or work network and a public network. In different network situations, we can easily and conveniently switch profiles, select different levels of network protection measures. If we are in a home network, other computers and devices are familiar to us, then the configuration files allow incoming connections, you can easily share pictures, music, video and document library, you can share hardware devices, such as printers, and so on, and if you bring this notebook to the airport, coffee bar and other public places, So in a public network such as wireless connection must pay more attention to connection security, may need to interrupt some incoming connections, now through Windows Firewall we can easily switch the network location to "public network" to obtain more secure security protection.





for the configuration of different network locations, we can also make some fine-tuning and open settings. Click the "Change notification settings" or "Firewall switches" on the left side of the Windows Firewall interface, and you can also go to the "Custom settings" interface, where we can fine-tune the settings for various network locations, such as firewall opening, notification mode, blocking incoming connections, and so on. Windows Firewall blocks connections to programs that are not on the list of allowed programs, but it is common for seven to recommend that all incoming connections be blocked in the public network to improve security, but this does not affect general web browsing and instant messaging.





(tips: How to change your own network location?) In Control Panel, select Network and Internet-Network and Sharing Center, click the network type area on the interface, and then select it in the Set Network Location window that pops up. ）





If you know more about Windows 7 firewall settings, you can go to the Advanced Security Settings console by clicking Advanced Settings on the left. Here, we can set up for each type of network configuration file, edit inbound, outbound rules, and so on, of course, if you are not "veteran", can completely ignore this advanced settings function.





in the "Allowed programs" setting of the firewall, we can set up and manage programs that allow you to communicate through firewalls, you can add the programs you want to use, give them permission to allow communication, and trust that these settings are not unfamiliar to anyone else, and so are other Third-party firewall programs. , there is no more to say.





from the above we can see that the Windows 7 firewall in the function and use of a lot of improvements, I believe it can bring us a pragmatic network firewall protection, but no longer is the eyes of the "chicken".　 Let's look at other security features of Windows 7.





second, humanized classification set user Account Control trial





User Account Control (UAC) is a feature introduced by Windows Vista systems that can monitor important changes in your computer and ask permission changes to help prevent malicious programs from damaging your system. In Vista, UAC is as much criticized as Windows Firewall, mainly because it brings a lot of operational trouble to users.





in Windows 7, UAC has been less disruptive and more flexible: Windows 7 programs and tasks that require not only user consent are reduced, but there are four levels of settings in the UAC settings. Allows us to fine-tune the notification settings for UAC through an account with administrator privileges-the most significant improvement in UAC functionality in Windows 7.




The settings for
UAC are also available in the system and security options in Control Panel. After opening the settings interface, we can choose the security level according to our own needs.　　 There are descriptions and recommendation levels in every security level, so you don't have to worry about how to choose.





If you are accustomed to using user Account Control, the new changes in Windows 7 will certainly make you more comfortable with UAC





third, care for children computer use easy control Parental controls




Having children in a
family is often a very troubling problem------------------------------------------------- Now the Parental Control feature in Windows 7 will solve these problems, not only to help limit the time that children use the computer, but also to limit the programs and games they use, to monitor what they say and to keep away from bad information.





as a security feature of Windows 7, parental controls are not placed in the system and security options in Control Panel, but are found in the user account and home security options.





to use parental controls, first the administrator account must have a password set, otherwise any user can skip and turn off parental controls, and then create a user account specifically for the child. In the Parental Controls interface, click the "Create a user Account" button, and then follow the prompts to complete the remaining creation steps, such as creating a new account called "CS" for example.





When you are finished creating, click the user account "CS" that you want to set parental control on, go to the user control interface, and under parental Control, select Enable, force current settings.





Next, we can adjust the settings we want to control for our children's accounts. One of the most important time limits, you can prevent the computer from being logged in at a specified period. Here, we can set a different logon period for each day of the week, so we just mark the forbidden period in the time table with a blue sign. If it is still logged in after the allotted time has ended, it is automatically logged off.





in Game control, we can control access to the game, select an Age rating level, select the type of content to block, determine whether to allow or block unrated games or specific games. However, seven of the game to control this function is not very suitable for the domestic, because the current domestic game market does not have the grading level of the game System division, so in the block, allow the operation of which games is not very good.





In addition, parental controls allow you to set up which programs your child's account allows to run, and by installing additional parental controls from third-party providers, you can also use these controls in parental controls to manage how children use computers, such as web filtering and activity reporting, The seven of you here no longer detail what is included with Windows 7.





Now, with Windows 7 Parental control, even if you don't stand behind a child, you can limit your child's use of the computer to help them use the computer properly and stay away from cyber-hazard information.





Four, the data security has the safeguard detailed explanation BitLocker disk encryption





BitLocker Drive Encryption is a very important security feature in Windows 7 that is used to encrypt the entire system partition of a computer to protect the user's data security, as well as to encrypt removable storage devices such as U disk and removable drives, which is even more important The use of BitLocker encryption after the loss of the USB disk can also ensure that their data security, to solve the portable storage device lost data leakage caused by. Now let's try the use of BitLocker.





open windows 7 Computer, right-click the drive you want to encrypt in the list of disk partitions, and then select Enable BitLocker on the menu. Starting now, the Operation Wizard will guide us through the encryption of this partition.




The first thing to
is how to unlock the drive. In this case, BitLocker provides us with several decryption methods, including the most familiar password unlock, also use the smart card to unlock the way and automatic unlock on this computer.





under normal circumstances, seven as everyone will choose the way to unlock the password, because this is the most convenient use, here we take the password to unlock the way for example. After setting the password to enter the next step, the wizard will ask us to choose the way to store the recovery key, and choose one of our own convenience. For this step, seven are reminded to pay attention to, because once you forget the password or lose the smart card, you can access the encrypted drive through the key. This function can be said to be very intimate, for the possible general to leave a retreat.





complete the above steps to open the encryption. The entire encryption process takes a certain amount of time depending on the size of the disk partition, but this time may be unexpected, because it can take a considerable amount of time. Seven Aberdeen in the encryption, more than 70 GB of disk partitions in one hours to complete, this is more unsatisfactory.





When you restart your computer after encrypting it, you can see that the encrypted disk plus the Golden Lock flag, does it look like it's safe? When you double-click the partition for access, BitLocker asks for a password to unlock the drive, and, of course, all the information and content of the partition can be accessed only if you enter the correct password.





Open Encrypted disk partitions are marked with an open gray lock and can be viewed in the status bar to see information about the partition, such as space usage, file system, and so on. Double-click the icon to enter the partition, as usual to view, modify the file.





If you want to remove encryption for this partition in the future, we can turn on system and security-BitLocker Drive Encryption-in the control Panel, where you can manage all of the disk partitions. You can suppress encryption by selecting "Turn off BitLocker" on an encrypted drive. Of course, like encryption, decryption also takes a lot of time. If you click Manage BitLocker, we can see the interface shown in Figure 22 for some maintenance and management of BitLocker encryption.





BitLocker Disk Encryption is not complex, and is fairly secure, easy to use, and is now easy for Windows 7 operating system users to encrypt their local drives or removable storage devices.　　 However, the seven think BitLocker disk Encryption also has some disadvantages, can only encrypt the entire disk partition, but not a separate folder, if you can achieve such a function, I believe that in the daily use will have a greater role.





now, with the full range of Windows 7 security features, we not only have the confidence to use the computer, we do not have to worry about the problems of the children using the computer. If you are accustomed to the virus protection software and so on, I believe we can stay away from the vast majority of viruses, trojans and all kinds of harmful acts of intrusion!
