IPv4 DoS Policy

[fionaC]

I am looking to enable IPv4 DoS policies which are recommended practice. 

However, I am concerned about impact. Does anyone have any recommendations for enabling these? 

Should I do them one at a time? Is it safe to do them all at once? Are there some I should not enable etc?

Should I leave them at the default thresholds? 

Thanks,

Depends, what exactly are you trying to prevent.  If you need DoS prevention you are usually better served with various cloud based offerings that will stop the traffic before it even reaches your FortiGate.

That is not an option as we are very small.

Hi @fionaC, 

I don't think there will be any impact. However, legitimate traffic might be blocked if the threshold is exceeded. Usually, the default thresholds are good. However, you can modify them based on your environment.
