Chromebook system without anti-virus software

Chromebook Adhere to the principle of in-depth protection , Provide layers of safety protection measures , Even if you avoid a layer of security , There are multiple layers of protective measures ready for help . Although users themselves should be careful to protect their data , but Chromebook The design of can still make people feel a little relieved . Chromebook The built-in safety protection functions include ：

One 、 Auto update

The most effective way to prevent malicious software attacks , It is to ensure that all software is kept up to date and subject to the latest security amendments . The traditional operating system has many software components from different manufacturers , Each has its own update mechanism and user interface , This aspect of management may be difficult . Chromebook Can automatically manage updates , Therefore, it can execute the latest and safest software version at any time . I especially want to update the mobile phone operation . comparison Windows Program update for , It's really much better .

Two 、 Use sandbox mechanism

Chromebook Every web page and Application on is executed in a restricted environment , This environment is called 「 The sandbox 」. If Chromebook Connected to the infected web page , Other pages in the computer 、 The application or other parts will not be affected at all , It can stop the threat of malware . This applies the current expensive sandbox design to every machine chromebook, And it's free .

3、 ... and 、 Verify the boot procedure

Even if malware tries to avoid sandbox protection ,Chromebook Still protected . Chromebook Every time it starts , It's all going on 「 Verify the boot procedure 」 Self checking mechanism . If any tampering or damage to the system is detected , Verify that boot programs can usually easily repair themselves , Give Way Chromebook The operating system is as good as new .

Four 、 Data encryption

stay Chromebook When using web applications on , All important data will be safely stored in the cloud . Certain types of files may still appear on the computer , For example, downloading items 、Cookie And browser cache files . Chromebook Use tamper proof hardware to encrypt data , Make it difficult for others to access these files . The target should be Windows Of BitLock encryption , Encryption through hardware , Avoid data tampering .

5、 ... and 、 Restore mode

If Chromebook Any problems , You just press a button or use a shortcut key combination , You can enter recovery mode , Restore the operating system to a well-established version . This ratio Windows The restore point of is designed to be easy to use .

Said at the end ： The more complex the system design , There are bound to be more and more security vulnerabilities ,Windows、Internet Eexplorer、adobe flash And so on . Although it can not be used directly in China , But I hope chromebook The security mechanism can change the past Windows and Linux Security design of operating system , Security hardening doesn't require so many registry changes 、 Group policy, etc .
