Redmine PRELUDE SIEM - Bug #1253 (New): Support on K8s Prelude Siem versionhttp://www.prelude-siem.org/issues/12532022-06-16T08:36:22ZQuentin Maraval
<p>Hello,<br />i am currently working on the "chartization" of Prelude in order to get it running inside Kubernetes cluster.<br />I used this repository <a class="external" href="https://github.com/fpoirotte/docker-prelude-siem">https://github.com/fpoirotte/docker-prelude-siem</a> that does the same work for docker with OSS version of prelude.</p>
<p>I updated the docker image, changed the Os container from Centos to Opensuse leap.<br />I have the project running (not tested the correlator yet), however it still on OSS version and i would like to get it running in SIEM version.</p>
<p>So to achieve this i will need some support from you on this task.</p>
<p>I have a couple questions :<br />- Where can i download the packages for SIEM version for Opensuse ? <br />- How can we proceed for key generation/licence knowing that the helm chart deployment can occurs many times as we are on cloud (delete/reinstall for testing purpose etc..)</p>
<p>Thanks,<br />Quentin</p> Prewikka - Support #1153 (Assigned): Suricata changes the output from version 4http://www.prelude-siem.org/issues/11532019-11-07T18:40:10ZAndrew Goldy
<p>Hello Guys!</p>
<p>Suricata might has changed? the default prelude-alert output, because comparing to the old release 3.x the alert text was the alert name for example "ET POLICY Self Signed SSL Certificate (SomeOrganizationalUnit)", and now the alert text is swapped to description for example "Potential Corporate Privacy Violation".<br />Moreover comparing to snort its confirmed something was wrong with the alerting output at least in case of prelude in suricata.</p>
<p>Below the real world examples with the same alert from snort and suricata aspects. Both outputs are natively forwarded to prelude. <br />I've contacted suricata for months but still no answer... Is there any workaround to swap the two columns regarding suricata?</p>

<p>Hello, <br />I'm trying to set up the latest version of prelude OSS on raspbian. With some effort I installed almost everything. <br />However, I have a problem with prewikka whose installation doesn't work. I have installed all the dependencies.<br />But I'm getting some errors when I run this command -> python setup.py install</p>

<p>Hi,<br />I have a problem to register my IDS (Suricata) on Prelude OSS. My IDS is on the same network but in a different CentOs VM. The prelude address is 192.168.0.2 and the IDS address is 192.168.0.3<br />I already installed from source : prelude-manager, prelude lml (not used), prelude-admin and libpreludedb. I configured the /usr/local/etc/prelude/default/client.conf<br /> to change the server-addr=127.0.0.1 to server-addr=192.168.0.2<br />Same for prelude-manager.conf with listen = 192.168.0.2:5553<br />I verify the connection between my IDS and my Prelude with a ping.<br />Then I enter the command line on the prelude machine :<br /> prelude-admin registration-server prelude-manager<br />and on the IDS :</p>
<p>prelude-admin register suricata "idmef:w admin:r" 192.168.0.2 –uid 1000 –gid 1500</p>
<p>I copy the one shot password but get this error message on my IDS :<br />Connecting to registration server (192.168.0.2 :5553)<br />Could not connect to 192.168.0.2 port 5553 : No route to host<br />So I scan my port and the number 5553 remains closed throughout all the process. <br />I may have missed a command line or configuration, so i reread the whole doc but I didn’t found anything about it.</p>
<p>Do you have any suggestions?</p>
<p>Thanks.</p> Prelude Correlator - Feature #375 (Assigned): Prelude Correlator upper event limithttp://www.prelude-siem.org/issues/3752010-04-06T19:40:57ZJames Chappleheatgod@verizon.net
<p>When a corrleated event such as Eventscan or Eventstorm contains large numbers of events, the Prewikka GUI times out and is unable to display the event details. On several test systems available to me, the threshold seemed to be around 5K events. This was discovered during a Nessus scan of monitored systems, where Nessus is scanning every port. Iptables is logging every blocked port, potentially generating many thousands of events during the window.</p>
<p>The ability to specify an upper limit in the Correlator rules for a given correlated event would be useful to prevent excessive messages in a single event.</p> PRELUDE SIEM - Bug #349 (New): SANCP - problem on installhttp://www.prelude-siem.org/issues/3492009-05-18T09:27:51Zjulien aussibaljulien.aussibal@univ-pau.fr
<p>Hello everybody,</p>
<p>I'm trying to install sancp on my computer for looking my network.</p>
<p>First, the link of the tar.gz is dead on this page (<a class="external" href="https://dev.prelude-ids.com/wiki/prelude/InstallingAgentThirdpartySancp">https://dev.prelude-ids.com/wiki/prelude/InstallingAgentThirdpartySancp</a>) .</p>
<p>Secondly, I found a different version on this page : <a class="external" href="http://metre.net/files/">http://metre.net/files/</a><br />but the lastest version doesn't compile with prelude option.</p>
<p>Anybody have a stable version of sancp working with prelude ? Could you indicate how to configure it to log Alert in prelude-manager.</p>

<p>Hey there,</p>
<p>I would suggest the following feature for prewikka: In the detailed alert view</p>
<p>/?view=alert_summary&origin=alert_listing&messageid=$alert.messageid</p>
<p>there should be the possibility to view this event in pure IDMEF XML, too. This would make it easier to get an IDMEF overview and indepth view, as well as it makes it easier to create rules/filters on IDMEF criteria, i.e. if using the smtp plugin or just some other custom filters</p> Prewikka - Feature #240 (New): [PATCH] - SSL Client Certificate Authentification modulehttp://www.prelude-siem.org/issues/2402007-06-18T16:58:01Z
<p>Hi</p>
<p>Here is a patch to use a SSL Client certificate to authenticate user. The username should be equal to the user certificate CN (the full DN is too long to be used, login field is limited to 32 char)</p>
Limitations:
<ul>
<li>Currently only tested in a SSL mod_python setup</li>
<li>Need SSLOptions +StdEnvVars</li>
<li>Used with python 2.3</li>
</ul>
<p>In prewikka.conf</p>
