In the digital world, system security has always been an old topic, ranging from personal privacy diaries to corporate bidding documents, and which ones are indispensable for encrypted files. I remember a few years ago, Xiaobian once saw a movie, saying that a female protagonist is going to peek at the data in the actor's computer, but she is unable to crack the Win98 login password (not Win8 Ha ~). Really, this scene can be really speechless. It is well known that Win98's login password is only used to verify network permissions. If you log in to the machine, you can click Cancel directly, but this MM has been troubled by such a problem for a long time. It is really difficult. Understand the director's intentions. But what about the game, this drama is the first time that I have personally felt the meaning of file encryption. In fact, with the continuous development of the operating system, today's Win7 is more focused on data security, not only provides a higher level of login protection (now do not expect to click to cancel can log in ~), but also file and hard disk level encryption Let's take a look at it with Xiaobian.
a landing encryption
landing Win7 security has been greatly improved, not only put an end to the illegal behavior is not lost login password, which is also far more difficult to crack password before the system (such as XP, Password cracking has failed for Win7. It can be said that general malicious attacks will become helpless in the face of Win7.
In addition to this basic design, Win7 also added some small features, such as "Local Security Policy → Security Settings → Local Policies → Security Options" "Interactive Login: Do not display the last The file name can be used to automatically hide the username of the login interface, in case someone else guesses the login password based on the account number and the user icon. Or you can set the system login to force Ctrl+Alt+Delete, which will further improve Win7 login security.
three full-disk encryption
Although EFS encryption really strong, but not the entire drive encryption (only for file folders and a single plus Decryption), in many cases, this limitation makes encryption very cumbersome, so Win7 has added a new design - BitLocker designed for full disk encryption. Like EFS encryption, Bitlocker is also very simple to use. Normally just right click on the drive you want to encrypt and select "Enable BitLocker". Different
and EFS is, BitLocker provides additional encryption and decryption, the user can not only enjoy a similar native EFS automatically unlock (note that this is the machine, instead of this account), also The encryption key can be generated with a password or smart card. As for security, don't worry, it is no different from EFS.
Written at the end
As you can see, in fact, Win7 has already built a system security mechanism for us, and use them properly to ensure that files are flawless. Of course, the old saying goes, there is no constant security, there is no constant rule, as long as good computer usage habits are maintained, the hacking Trojan will stay away from you forever!
