@ -124,6 +124,15 @@ HardenedBSD does not permit such behavior.
jemalloc in HardenedBSD has been set to zero new allocations by
default.
Process tracing (`ptrace`) is hardened:
* Process tracing facility itself is disabled by default
(`security.bsd.allow_ptrace=0`).
* Unpriviledged process debugging is prohibited by default
(`security.bsd.unprivileged_proc_debug=0`).
* Remote syscall functionality (`ptrace(PT_SC_REMOTE)`) is prohibited by
default.
