<p class="MsoPlainText"><span lang="EN-GB">GÉANT have recently made some improvements to the scrubbing capabilities of the DDoS C&A service, including the following enhancements (which are now in production):<o:p></o:p></span></p>

<li class="MsoPlainText" style="mso-list:l1 level1 lfo3"><span lang="EN-GB">In the last quarter we have increased the scrubbing capacity of our A10s from 40G to 100G. This gives us the ability to re-route and cleanse larger volumes of traffic and provide an
improved service to NRENs.<o:p></o:p></span></li></ul>

<ul style="margin-top:0cm" type="disc">
<li class="MsoPlainText" style="mso-list:l1 level1 lfo3"><span lang="EN-GB">GÉANT SOC has reviewed our current scrubbing solution configuration and subjected it to a complete overhaul. With every mitigation template being fine-tuned to provide more specified
and accurate scrubbing and include more of A10’s proprietary scrubbing enhancements. In addition, we have included zonal escalations that will happen automatically in the event mitigation is started. The enhancements should be noticed most prominently with
UDP based attacks such as DNS reflection and amplification. GÉANT’s review and refining of these templates is ongoing.<o:p></o:p></span></li></ul>

<ul style="margin-top:0cm" type="disc">
<li class="MsoPlainText" style="mso-list:l1 level1 lfo3"><span lang="EN-GB">ZAPR is a dynamic attack pattern recognition system powered by machine learning algorithms. After the learning phase is complete (currently started as soon as the mitigation zone is
opened), ZAPR implements rules tailored specifically to the attack it is analysing (testing shows this to take less than 2 minutes following peace time, though this was in a simulated environment). ZAPR is now enabled in production on every relevant mitigation
template.<o:p></o:p></span></li></ul>
