Redmine Libprelude - Bug #887 (New): Timer tests on slow systemhttp://www.prelude-siem.org/issues/8872017-05-14T14:22:27ZThomas ANDREJAKthomas.andrejak@csgroup.eu
<p>On slow system, sometimes, timer tests (tests/prelude-timer.c) work works.</p>
<p>Adding "1" to max_expire in for loop solve this</p>
<pre>
- for ( i = 0; i <= max_expire && timer_alive; i++ ) {
+ for ( i = 0; i <= max_expire + 1 && timer_alive; i++ ) {

<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>Thanks</p> PRELUDE SIEM - Bug #343 (New): OSSEC-HIDS 1.6.1 always sets assessment.impact.completion = succededhttp://www.prelude-siem.org/issues/3432009-01-25T20:06:12Z

</pre> 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>

<p>Some LML rulesets are missing an "url" field for the Classification Reference. IDMEF specify that the "url" member of a Reference has to be specified.</p>

<p>Current rulesets (except modsecurity) does not make use of the IDMEF Action class.</p>
<pre>
4.2.6.2. The Action Class
The Action class is used to describe any actions taken by the
analyzer in response to the event.
category
The type of action taken. The permitted values are shown below.
The default value is "other". (See also Section 10.)
+------+-------------------+----------------------------------------+
| Rank | Keyword | Description |
+------+-------------------+----------------------------------------+
| 0 | block-installed | A block of some sort was installed to |
| | | prevent an attack from reaching its |
| | | destination. The block could be a |
| | | port block, address block, etc., or |
| | | disabling a user account. |
| | | |
| 1 | notification-sent | A notification message of some sort |
| | | was sent out-of-band (via pager, |
| | | e-mail, etc.). Does not include the |
| | | transmission of this alert. |
| | | |
| 2 | taken-offline | A system, computer, or user was taken |
| | | offline, as when the computer is shut |
| | | down or a user is logged off. |
| | | |
| 3 | other | Anything not in one of the above |
| | | categories. |
+------+-------------------+----------------------------------------+
The element itself may be empty, or may contain a textual
description of the action, if the analyzer is able to provide
additional details.
