It looks like you are mixing two entirely different computer science concepts: SECCOMP (a Linux kernel security feature) and Secure Spreadsheet tools. There is no official, singular technology called “SECCOMP – The Secure Spreadsheet.”
Because spreadsheets like Excel and Google Sheets can run macro code or external processes, developers frequently use SECCOMP to sandbox those applications. Conversely, companies use specialized enterprise software like SecureSheet to isolate cell data.
The breakdown below explains both technologies and how they interact. 1. What is SECCOMP?
SECCOMP (short for Secure Computing Mode) is a security facility built directly into the Linux kernel. It functions as a sandboxing tool to restrict what system calls (syscalls) an application can make to the operating system.
How it works: A standard application has access to hundreds of system calls. SECCOMP forces the process into a strict “one-way” secure state where it is only allowed to perform foundational actions like reading, writing, and exiting (read, write, exit, sigreturn).
Why it matters: If a hacker compromises an application, SECCOMP blocks them from executing malicious, unexpected code (like restarting a server or erasing a hard drive) because the kernel will immediately kill the process if an unauthorized syscall is attempted.
Modern Expansion: Modern Linux environments use Seccomp-BPF, which allows administrators to use flexible “allow lists” or “deny lists” tailored to specific application profiles. It is heavily used to isolate workloads in Docker container runtimes and Kubernetes clusters. 2. What is a “Secure Spreadsheet”?
When people look for a “secure spreadsheet” in an enterprise or programming setting, they are usually referring to one of two things: A. SecureSheet (Enterprise Cloud Platform)
