Comprendre les attaques DoS et DDoS : leur impact, tendances et stratégies de mitigation

Bernard Sfez - 2024-11-11 15:07

Les attaques par déni de service (DoS) et déni de service distribué (DDoS) comptent parmi les menaces de cybersécurité les plus perturbatrices pour les entreprises et les gouvernements. Ces attaques consistent à saturer un système de requêtes afin de le rendre inaccessible, provoquant ainsi des interruptions de service importantes. Alors que les attaques DoS sont généralement lancées depuis une seule source, les attaques DDoS utilisent de multiples sources, ce qui les rend beaucoup plus difficiles à contrer.

Les récentes tendances révèlent une nette augmentation des attaques, illustrée par l’exploitation en 2023 d’une vulnérabilité critique du protocole HTTP/2. Cet incident a poussé des géants technologiques comme Google et Amazon à déployer des mesures de protection en urgence, comprenant des fermetures de passerelles et des investissements substantiels dans des systèmes d’atténuation pour maintenir la continuité de leurs services.

Cet article examine ces menaces et présente des stratégies clés pour réduire les risques, comme l'utilisation de services de protection DDoS, de protocoles de sécurité réseau, de méthodes d'authentification sécurisées et d'une surveillance proactive. En appliquant ces stratégies, les entreprises peuvent considérablement réduire leur vulnérabilité face à de telles attaques et protéger leurs infrastructures critiques.

Tiki Wiki SEO, Sitemap Issue and Solution

Bernard Sfez - 2024-08-06 09:57

From Tiki Wiki versions 25.x to 27.0 the sitemap feature may generate an incorrect URL for submission to search engines. Specifically, the URL points to tiki-sitemap.php?file=sitemap-index.xml, which can cause errors when submitted to Google Search Console.

To use the sitemap feature, ensure the "Sitemap Protocol" is enabled:

  1. Navigate to Settings → Control Panels → General Settings → Navigation Admin Panel (direct URL: /tiki-admin_sitemap.php).
  2. Additional settings and explanations about the Tiki sitemap can be accessed via the gear icon (settings button) on the same page.


You will find the URL intended for submission to search engines, but it is incorrect. OpenSource Solutions provides a detailed guide on how to resolve this issue.

Future versions of Tiki (from Tiki27.1) introduce a new panel under Advanced → SEO Preferences
