[nsp-sec] Question on attack flow quantitiy

[Joel Rosenblatt]

Hi,

We have been seeing big spikes in our external attack flows (see graph - it is the last 24 hours) - we typically see about 50k flows per 5 minute interval - we 
have been seeing upward of 150k for the last few days.

The vectors are spread around over lots of attack ports.

Is everyone else seeing this, or do I have a big target painted on me somewhere?

Thanks,
Joel
