The first thing to set is the way to unlock the drive. Here BitLocker provides us with several ways to decrypt, including the most familiar password unlocking, the use of smart card unlocking methods and automatic unlocking on this computer.
Under normal circumstances, seven earners as everyone else would choose a password to unlock the way, because it is most convenient to use, here we have to unlock the password mode as an example. After setting the password above, go to the next step. The wizard will ask us to choose the way to store the recovery key, and choose one according to its own convenience. For this step, Qizai reminds everyone to pay attention to it, because once the password is forgotten or the smart card is lost, the encrypted drive can be accessed by the key. This feature can be said to be very intimate, leaving a way for everyone's possible ideas.
1, child care, computer use parental controls to easily manipulate
families with children use computers tend to be a very vexing problem - that is not completely do not allow children to use the computer, and difficult Better control and supervision of the child's use of the computer. Now the parental controls in Windows 7 will solve these problems. It not only helps limit the time children spend on computers, but also limits the programs and games they use, monitors what they say and keeps away from bad information.
As a security feature of Windows7, parental control is not placed in the "System and Security" option in the Control Panel, but can be found in the "User Accounts and Family Safety" option.
to use parental controls, of course, there must first administrator account password, otherwise any user can skip and turn off parental controls; secondly a user account created specifically for children. In the "Parental Control" interface, click the "Create a User Account" button, and then follow the prompts to complete the remaining creation steps, such as we create a new account named "cs" as an example. After
finished creating, you want to set Parental Controls user account "cs", enter the user control interface, and then under "Parental Controls", select "Enable to force the current settings."
Next, we would be able to adjust the child's account settings to be controlled. One of the most important time limits is to prohibit logging in to the computer at the specified time. Here, we can set a different login period for each day of the week, we just need to mark the forbidden time zone with a blue mark in the time table. If it is still logged in after the time allotted, it will be automatically logged off.
game in control, we can control access to games, choose an age rating level, select the type of content you want to block, determine whether to allow or block unrated or specific games games. However, Qizai believes that the game control function is not very suitable in China, because the current domestic game market does not systematically divide the game's hierarchical level, so it is not very good to block and allow which games are operational. .
In addition, parental controls can also be set by the child's account is allowed to run what programs; and by installing additional parental controls from third-party providers, you can also use these controls in Parental Controls to manage child Using computer methods, such as web filtering and activity reports, here, Qi Zi will not elaborate on the contents of Windows 7.
now, Windows7 through parental control functions, even when not standing behind the children, the children can also limit the use of computers to help them reasonable use of computers, networks away from the hazard information.
2, get rid of "chicken" in the name of exploring the new Windows Firewall
Windows XP firewall is a system from the beginning built a security defense system, designed to help users protect their computers, from hackers and malicious Software attack. But 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. Fortunately, after
experienced excessive WindowsVista, the Firewall feature in Windows7 started to show "professional" flavor. 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 Windows7 Firewall, favorite of the seven earners that its ease of use, controlled through options in the panel you can complete all settings and adjustments, but for most ordinary users, settings The only action required 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 "Windows Firewall" option.
into the Windows Firewall Control Panel option, perhaps your Windows7 system does not turn on the firewall function at the interface will be prompted, seven earners suggest that you turn on Windows Firewall to stay safe online. Just click "Use recommended settings" to have Windows Firewall automatically start using the recommended settings to protect your computer.
In Windows7, Windows Firewall default network into your home or work and public networks. 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.
configuration status for different network locations, we can also do some fine-tuning and open setting. Click "Change Notification Settings" or "Firewall Switch" on the left side of the Windows Firewall interface, you can also enter the "Custom Settings" interface, where we can fine-tune the settings of various network locations, such as firewall open, notification Ways, block incoming connections, and more. 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. ?
(Tip: How to change your network location then select "Network and Internet" in the Control Panel in order - "Network and Sharing Center" and then click on the type of network interface region, and then in the pop-up "set network location" window, you can select.)
If you compare Windows7 understanding of the various firewall settings, you can click on the "advanced settings" on the left, 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 a "old bird", you can completely ignore this advanced setting function.
the firewall "permit program" setting, we can already set up to allow the program to communicate through the firewall to set up and manage, you can you use to the program are added in, give them a permit The authority to communicate, I believe that these settings are not unfamiliar, other third-party firewall programs are also the case, here will not say more.
From the above we can see that the firewall Windows7 in functionality and use have a lot of improvement, we believe it can bring surly network firewall protection for us, and we are no longer seen as "tasteless ". Let's take a look at the other security features of Windows 7.
3, humane rating User Account Control settings trial
User Account Control (UAC) is a feature introduced in WindowsVista system starts, it can monitor important changes to the computer and asked if License 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.
In Windows7, UAC generates interference has been reduced, but also more flexible: not only need to seek the consent of the user Windows7 program and reduce the task, UAC settings and provides four levels of settings, let us UAC's notification settings can be fine-tuned through an account with administrator privileges - this is the biggest improvement in UAC functionality in Windows 7.
UAC settings can also be found in the "System and Security" option in the Control Panel. After opening the settings interface, we can choose the security level according to our needs. There are descriptions and recommendations at each level of security, so you don't have to worry about not knowing how to choose.
If you are accustomed to using User Account Control function, the new changes in Windows7 UAC will make you use more liking.
4, Detailed data safe and secure BitLocker disk encryption
BitLocker Drive Encryption is Windows7 in a very important safety feature, which can be used to encrypt the entire system partition computer in order to protect users Data security, you can also encrypt removable storage devices, such as USB flash drives and mobile hard drives, which is even more important - even if you lose your USB flash drive after using BitLocker encryption, you can ensure your data is safe and solve the loss of portable storage devices. And the resulting data leaks. Let's try the use of BitLocker.
open Windows7 "computer" in the partition list, right-click the drive you want to encrypt, and then select "Enable BitLocker" in the menu. Now, the wizard will guide us through the encryption of this disk partition.
completion of the above steps to open encrypted. The entire encryption process takes a certain amount of time depending on the size of the disk partition, but this time may be unexpected, as it can take a considerable amount of time. When seven children were encrypting, more than 70 GB of disk partitions took more than an hour to complete, which is quite unsatisfactory.
after the completion of encryption restart your computer, then you can see the encrypted disk coupled with the golden mark, it appears to be not very safe people feel it? Double-click on the disk partition to access it. BitLocker will ask for a password to unlock the drive. Of course, all the information and content of the partition can be accessed only by entering the correct password. After
open the encrypted disk partitions will be marked in gray lock is on, and then select can view the information in the status bar to partition the disk, such as space usage, file system, and so on. Double-click the icon to enter the partition and view and modify the file as you normally would.
if in the future you want to cancel the encrypted disk partitions, we can open the "System and Security" in the Control Panel in order - "BitLocker Drive Encryption", where you can manage all of the disk partitions. Unencrypt by selecting "Turn off BitLocker" on the encrypted drive. Of course, as with encryption, decryption takes a lot of time. If you click on "Manage BitLocker", we can see the interface shown in Figure 22, which can be used to maintain and manage BitLocker encryption.
BitLocker disk encryption method is not complicated, and quite safe, easy to use, convenient, Windows7 operating system users can now easily encrypt their local drive or a removable storage device. However, Qizai believes that BitLocker disk encryption also has certain disadvantages. It can only encrypt the entire disk partition, but cannot encrypt a folder separately. If it can achieve such a function, it is believed to have a greater role in daily use.
now, Windows7 through a full range of security features to protect, not only they can safely use your computer, do not worry about the problems for the children to use the computer. If you cooperate with the virus protection software you are used to, I believe that everyone can stay away from most viruses, Trojans and various harmful behaviors!
in the operating system, security has always been the people most concerned about, but also the most concern. 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.
