# efdn-security

Linux seccomp helpers for Elios services.

`efdn-security` builds syscall allow lists with typed rules. Services can allow
known syscalls, return errno for declared violations, or kill a process that
leaves its declared boundary.

Applications usually enable it through `efdn`:

```toml
[dependencies]
efdn = { version = "0.3.1", features = ["security"] }
```

The crate only installs seccomp policies on Linux.
