Class ProcessHardening

Namespace

FishMMO.Auth.Implementation

Assembly

FishMMO-AuthShared.dll

OS-level hardening hooks invoked early during server startup to reduce the risk that sensitive in-memory key material (TOTP KEK, signing keys, SRP verifier) leaks via process core dumps or ptrace from unprivileged peers.

Remarks

On Linux, calling prctl(PR_SET_DUMPABLE, 0) disables core dumps and prevents non-root processes from attaching ptrace regardless of the global ptrace_scope setting. This call is a no-op on non-Linux platforms.

Methods

TryDisableCoreDumpAndPtrace(out string)

Attempts to disable core dumps and unprivileged ptrace on Linux. Returns true if the syscall succeeded; returns false on non-Linux platforms or if the syscall is unavailable. Failure is non-fatal — callers should log and continue.

public static bool TryDisableCoreDumpAndPtrace(out string status)

Parameters

status string

Returns

bool
