2. A professional software: sandboxie

Sandbox is a sandbox. Sandboxie is a professional virtual software.

Its working software uses redirection technology to direct the files generated and modified by the program to its own folder.

Of course, these data changes

include the registry and some core data of the system.

Protect underlying data by loading its own driver,

It is driver-level protection. I personally use Sandboxie to test viruses.

It can be said that running viruses in it is also a safe operation.

Computer vocabulary is generally used in the security field

For example, some anti-virus software detects viruses

Use a virtual environment to run suspicious programs to find out whether they have Destructive

There are also some famous sandboxies that protect the system

Sandbox (SandBox) < /p>

Security is a critical issue whenever code from a remote website is loaded and executed locally. Clicking a link launches a Java Web Start application. When you visit a web page, all Applets in it will also start automatically. If arbitrary code can be installed on the user's machine when a link is clicked or a web page is visited, criminals may eavesdrop on confidential information, read financial data, or take over the user's machine to deliver advertisements.

In order to ensure that Java technology will not be used for evil purposes, SUN designed a sophisticated security model when designing Java; that is, the Security Manager (Security

Manager ) will check all system resources you have permission to use.

By default, only harmless operations are allowed. To allow other operations, the code needs to be digitally signed and the user must be digitally authenticated.

What can remote code do on all platforms? It can display images, play music, obtain keyboard input and mouse clicks from the user, and send user input back to the host where the code is loaded. These functions are sufficient to be able to display information and pictures, or to obtain information entered by the user for an order. This restricted execution environment is called a sandbox. Code running in the sandbox cannot modify or view the user's system.

In particular, programs in the sandbox have the following restrictions:

● They cannot run any local executable programs.

No information can be read from or written to the local computer file system.

It is not possible to view any information about the local computer except Java version information and a few harmless operating system details. In particular, code in the sandbox cannot view information such as usernames and email addresses.

Remotely loaded programs cannot communicate with any host other than the server where the downloaded program is located. This server is called the originating host (originating

host). This rule, often called "remote code can only talk to family members" will ensure that users are not snooped by code into internal network resources (In Java SE 6, Java Web Start applications can connect to other networks, but User consent is required).

All pop-ups will come with a warning message. This message acts as a safety net to ensure that users don't get the wrong window for a native application. The concern is that a trustworthy user could visit the web page and be tricked into running remote code and then enter a password and credit card number, which information would be sent back to the server. In early JDK versions, there was a scary message: "Untrusted

Java Applet Window" (Untrusted Java Applet

Window). Later JDK versions softened the tone of this warning message to "Unauthenticated Java Applet Window" (uncertified Java

Applet Window). This is followed by "Warning: Java Applet Window" (Warning: Java Applet Window

). Now it's just "Java Applet Window" or "Java Appliation Window".

3. Concept of network theory

The specific thing is that Google will add a certain additional score to the new website, so that the ranking of the new website will rise rapidly (certain types of goals are key Character). In the subsequent period of time (about one to three or four months), the website's ranking will gradually decline, and some major keyword rankings will even disappear (even though your PR is very high and the page content is the same as before). This is like the sand flow in the desert slowly swallowing the surrounding objects

, so the industry named this phenomenon the sandbox phenomenon.

(Personally I think it’s the first one: games) To be honest, The sandbox is quite fun
