[ossec-list] Re: DDOS protection

["Daniel Cid" <daniel.cid@xxxxxxxxx>]

Hi DM,

It is very well possible. We already have rules like that for some
protocols, like
ftp, ssh ,etc but it can be easily expanded to others.

Example of rules like that (for ftpd):

  <rule id="11452" level="10" frequency="10" timeframe="60">
    <if_matched_sid>11401</if_matched_sid>
    <same_source_ip />
    <description>Multiple FTP connection attempts from </description>
    <description>same source IP.</description>
    <group>recon,</group>
  </rule>

Hope it helps.
