syscall restrictions

In the realm of Linux, security is a top priority, and one of the innovative tools for enhancing security is firejail. This sandboxing tool limits the scope of program operations using Linux namespaces and seccomp-bpf, which stands for Secure Computing Mode with Berkeley Packet Filter. Primarily, it's used to restrict the system calls that a process can execute. In this blog, we will explore how firejail can be used to restrict a script's access to specific syscalls. Q: Can you explain what firejail is and why it's useful? A: Firejail is a sandboxing tool that uses Linux namespaces and seccomp technology to restrict the running environment of untrusted applications.
