If you look at the the alert itself, you'll see that it's being triggered
by a remote system initiating an echo request to you. A normal "ping"
won't trigger this alert as normal pings don't have the required payload.
If you look at the reference for this alert,
you'll see some more information which will indicate you're being scanned.
If you don't want to know that you're getting scanned, go ahead and disable
it. However, if you're getting scanned a lot, which it sounds like you
are, it might be good to investigate.
