Computers are fundamental tools in many people's daily lives, so maintaining their care both externally and internally is one of the keys to their optimal storage and performance for a long time.
In addition to preventative maintenance, changing parts and other types of actions necessary to ensure it is 100% working, it never hurts to adopt some kind of preventive measure during the execution of a program which could damage the performance of your computer in some way.
Let's talk about the Sandbox
From that thought the idea of Sandbox was born, which is nothing more than a component that will contribute to the execution of programs in a safe way, reducing software risks unreliable and they can have enormously negative impacts on your computer's operating system.
What is the sandbox for?
As explained above, this data isolation process aims at protect all information and access of operating system of your computer from the dubious procedure or dubious reliability that a program might have.
- It also helps protect all information on your computer: documents, web browsers and communication or media exchange programs, all protected by the Sandbox.
- Optimize security parameters when install a program on your computer it can.
Sandbox operation
Some browsers and programs have implemented their own isolation tools for protect yourself and protect your computer from any malicious code.
In the case of programs to install or run, how does Sandbox work? The most used analogy has been that of the sandbox: this tool assigns a specific space to that program within the hard drive of the computer to install and run.
The technology of this important tool gives this program what it needs to run normally, without it being able to expand to other areas of your computer and influence them.
Ways to use Sandbox
This type of data protection tool is available in Windows and GNU-Linux operating systems through programs or add-ons. So, this time around, you will be able to know how to apply it in each of the operating systems.
Sandbox su GNU-Linux
For this type of operating system it is recommended to use the Firejail program. This recommendation is based on the broad scope it can have: protecting media transfer or communication programs (such as Skype, for example), web browsers, and audio and video players.
Its weight is light and it is easy to use. To use this tool, you will simply have to enter the command sudo apt-get install firejail. From there, you'll start with setting up your profiles:
- Define which folders the program can access.
- The permissions granted for its operation.
- The use of specific DNS.
- Define whether or not you have access to the Internet.
- If you want to configure a program profile, type the command: sudo nano /etc/firejail/programname.profile
- If you want to restrict Internet access to a program, enter the command firejail - net = none program name
Sandbox su Windows
To use Sandbox on Windows operating system, the procedure is a bit simpler. You just have to click on the start menu and follow the instructions:
- Type "Turn Windows features on or off". This will activate the search engine and you will be able to view the result and click.
- After that, a window will open in which you will check the Windows Sandbox box.
- Restart your computer.
- Click on the Start menu and search for Windows Sandbox.
This way you can enter the configuration interface of this tool and start increasing the security levels of your computer.
