+title: Configure SSHD PerSourcePenalties
+discussion: |
+  If SSHD is enabled then it _MUST_ be configured with the Per Source Penalties configured.
+
+  Per Source Penalities controls penalties for various conditions that may represent attacks on sshd.
+
+  Penalties are enabled by default.
+
+  NOTE: On macOS 15.2 and higher the SSH configuration can be reset to the macOS default by running /usr/libexec/reset-ssh-configuration.
