You might want to put your security system and other infrastructure hardware on a separate VLAN.

Not only does that help prevent stuff like this, it turns out that a lot of embedded hardware isn't that great from a network security perspective.

We didn't even have VLANs enabled on the switch back then.

And even then, the storm control is useful; the same broadcast storm also made the office wireless unusable (most APs use a basic rate for broadcast and multicast).
