[Slightly OT] How good is the mod_dosevasive default

[Elison Smith]

I am planning to put up a website which, like any other website, may get DoS
attacked. I have installed mod_dosevasive to protect against some degree of
application-layer DoS.

I understand that here are the default settings of mod_dosevasive -
(

)

<IfModule mod_dosevasive20.c>
    DOSHashTableSize    3097
    DOSPageCount        2
    DOSSiteCount        50
    DOSPageInterval     1
    DOSSiteInterval     1
    DOSBlockingPeriod   10
</IfModule>


Any experience how good this default works for the average website? I would
prefer to not spend time making changes to this default.

Thanks!
