      <body xmlns="http://www.w3.org/1999/xhtml">
        <p dir="ltr">
         S'il y a un sujet que je traite systèmatiquement avec les développeurs
      quand je suis sur des projets, workshops ou formations, et que je n'utilise jamais
      pour défendre une plateforme contre une autre, c'est la sécurité. Seulement, souvent,
      j'ai dans mes audiences des personnes qui vont arguer que tel system est plus sûr
      que tel autre, que Windows (que j'aime beaucoup pour diverses raison, mais que je
      ne recommande pas systèmatiquement car il y a aussi bien des situations ou ce serait
      idiot de penser qu'un passage à Windows améliorerait les problèmes, et il y a même
      des situations où Windows n'est pas le mieux placé - même si je reste convaincu qu'en
      entreprise ces situations sont rares) est bien plus vulnérable qu'un Linux ou qu'un
      Unix.
   </p>
        <p dir="ltr">
         Pour moi, c'est idiot de penser une telle chose, car les vulnérabilité
      sont nécessairement là. J'aimerais savoir comment il peut en être différement, vu
      qu'une vulnérabilité on ne peut sérieuse arrive facilement avec un buffer overrun,
      qu'un buffer overrun ne nécessite qu'une seule ligne de code mal écrite... Alors j'aimerais
      encore trouver l'équipe formée exclusivement de "Super Programmeurs" capable d'écrire
      quelques millions de lignes de code sans jamais laisser dérrière un buffer overrun
      ...
   </p>
        <p dir="ltr">
         Durant le dernier mois, on a commencé à reconnaitre un peu cette vérité
      chez les Linuxiens, avec deux vulnérabilités très sérieuses dans le noyau, et s'applicant
      à toutes les distributions de Linux dans le monde ... La première découverte
      lors d'un hack qui a touché le projet "Debian" (principale distribution non commerciale),
      et qui a exploité un buffer overrun qui existe dans toutes les versions du noyau antérieures
      à la 2.4.23, l'autre découverte cette semaine par un groupe de recherche polonais

      <description>&lt;p dir=ltr&gt;
   &amp;nbsp;&amp;nbsp; S'il y a un sujet que je traite systèmatiquement avec les développeurs
   quand je suis sur des projets, workshops ou formations, et que je n'utilise jamais
   pour défendre une plateforme contre une autre, c'est la sécurité. Seulement, souvent,
   j'ai dans mes audiences des personnes qui vont arguer que tel system est plus sûr
   que tel autre, que Windows (que j'aime beaucoup pour diverses raison, mais que je
   ne recommande pas systèmatiquement car il y a aussi bien des situations ou ce serait
   idiot de penser qu'un passage à Windows améliorerait les problèmes, et il y a même
   des situations où Windows n'est pas le mieux placé - même si je reste convaincu qu'en
   entreprise ces situations sont rares) est bien plus vulnérable qu'un Linux ou qu'un
   Unix.
&lt;/p&gt;
&lt;p dir=ltr&gt;
   &amp;nbsp;&amp;nbsp; Pour moi, c'est idiot de penser une telle chose, car les vulnérabilité
   sont nécessairement là. J'aimerais savoir comment il peut en être différement, vu
   qu'une vulnérabilité on ne peut sérieuse arrive facilement avec un buffer overrun,
   qu'un buffer overrun ne nécessite qu'une seule ligne de code mal écrite... Alors j'aimerais
   encore trouver l'équipe formée exclusivement de "Super Programmeurs" capable d'écrire
   quelques millions de lignes de code sans jamais laisser dérrière un buffer overrun
   ...
&lt;/p&gt;
&lt;p dir=ltr&gt;
   &amp;nbsp;&amp;nbsp; Durant le dernier mois, on a commencé à reconnaitre un peu cette vérité
   chez les Linuxiens, avec deux vulnérabilités très sérieuses dans le noyau, et s'applicant
   à toutes les distributions de Linux&amp;nbsp;dans le monde&amp;nbsp;... La première découverte
   lors d'un hack qui a touché le projet "Debian" (principale distribution non commerciale),
   et qui a exploité un buffer overrun qui existe dans toutes les versions du noyau antérieures
   à la 2.4.23, l'autre découverte cette semaine par un groupe de recherche polonais
   (ISE), s'applique à toutes les versions du noyau (y compris la 2.6)&amp;nbsp;&amp;nbsp;...
   l'une et l'autre des ces vunérabilités permet à un utilisateur quelconque d'exécuter
   du code en tant que&amp;nbsp;"Root", et donc de prendre possession complète de la machine
   ...
&lt;/p&gt;
&lt;p dir=ltr&gt;
   &amp;nbsp;&amp;nbsp; Si je ne suis la personne pour surfer sur de telles misères et dire que
   Linux est donc moins bon que d'autres, je pense tout de même qu'il est grand temps
   qu'on arrête de dire que tel ou tel système d'exploitation est plus sûre qu'un autre
   ... On peut préférer un système ou une plateforme pour toutes les raisons du monde,
   sauf pour celle de la sécurité ... Windows, Linux, Unix, ou autres, c'est le même
   combat ...
