Firejail Explained

Firejail is a security sandbox tool designed to enhance the security of applications by isolating them in a sandbox environment. It is a free and open-source software available for Linux-based operating systems. Firejail was created by Antti Kantee and is maintained by a community of developers.^{[1] [2] [3]}

Features

• Sandboxing: Firejail allows users to run applications in isolated environments, preventing them from accessing sensitive files and system resources.
• SELinux Integration: It integrates with SELinux (Security-Enhanced Linux) to provide robust security policies.
• Resource Limitation: Firejail can limit the resources (CPU, memory, etc.) that a sandboxed application can use.
• Network Isolation: It can restrict network access for sandboxed applications, enhancing security against network-based attacks.
• Filesystem Access Control: Firejail provides fine-grained control over which files and directories an application can access.

Usage

Firejail is typically used to run potentially untrusted applications or scripts in a controlled environment. It can be invoked directly from the command line or configured to run specific applications automatically.^{[4] [5]}
