So stoppen Sie einen DDoS-Angriff

Normalerweise würde sich jeder Websitebesitzer über Internetverkehr freuen. Es kann jedoch vorkommen, dass der Netzwerkverkehr störend sein kann. Bei einem solchen Cyberangriff handelt es sich höchstwahrscheinlich um einen DDoS-Angriff. Warum treten sie auf? Jeder DDoS-Angreifer, der diesen bösartigen Datenverkehr initiiert, möchte entweder, dass das angegriffene Netzwerk nicht mehr funktioniert, oder er fordert ein Lösegeld, bis der Eigentümer ihn dafür bezahlt, damit es aufhört.

Da verteilte Denial-of-Service-Angriffe (DDoS) in der heutigen digitalen Welt immer fortschrittlicher, wirkungsvoller und verbreiteter werden, ist die DDoS-Abwehr zu einem integralen Bestandteil Ihres Technologie-Stacks geworden.

Das Stoppen von DDoS-Angriffen ist jedoch alles andere als ein einfacher Prozess, und es ist für jedes Unternehmen unterschiedlich, den richtigen Weg zur Eindämmung dieser Art bösartiger Aktivitäten zu finden. Allerdings gibt es mehrere proaktive Maßnahmen, die Sie ergreifen können, um den Erfolg von DDoS-Angriffen zu verhindern.

Bevor wir näher darauf eingehen, ist es wichtig zu verstehen, was genau ein DDoS-Angriff ist.

Was ist ein Distributed Denial-of-Service (DDoS)-Angriff?

Wie unterscheidet man einen DDoS-Angriff von legitimem Datenverkehr? Im Kern ist ein Distributed-Denial-of-Service-Angriff (DDoS) ein schädlicher Versuch, den normalen Datenverkehr eines Netzwerks oder Servers zu stören, indem die Infrastruktur mit einer massiven Datenflut überlastet wird. Stellen Sie sich das vor, als stünden Sie im Stau. Sie versuchen, irgendwohin zu gelangen, können es aber wegen des vielen anderen Verkehrs auf der Autobahn nicht. In diesem Szenario handelt es sich bei einem DDoS-Angriff um den Stau, der Sie daran hindert, Ihr endgültiges Ziel zu erreichen, und die Angreifer blockieren nicht nur die Straßen, sondern tragen auch zum volumetrischen Angriff bei. Es gibt viele verschiedene Arten von DDoS-Angriffen, aber in diesem Beitrag liste ich einige der häufigsten Arten auf:

  • HTTP-Flut
  • Protokollangriffe
  • Volumetrische Angriffe
  • DNS- oder UDP-Verstärkung
  • Layer-7-Angriff (Anwendungsschicht)

So verhindern Sie einen DDoS-Angriff

Nachdem Sie nun verstanden haben, was ein DDoS-Angriff ist, welche Schritte können Sie unternehmen, um einen solchen zu verhindern? Bei der Verhinderung eines DDoS-Angriffs wird viel investiert, sie lässt sich jedoch in ein paar einfache Schritte unterteilen.

Der größte Faktor ist die Unterscheidung zwischen legitimem und bösartigem Datenverkehr. Wie oben erwähnt, gibt es verschiedene Arten von DDoS-Angriffen und manchmal sehen wir sogar DDoS-Angriffe mit mehreren Vektoren, bei denen verschiedene Angriffsebenen gleichzeitig stattfinden.

Dennoch ist die Implementierung einer Ratenbegrenzung eine gängige Methode zur Eindämmung eines DDoS-Angriffs. Dies bedeutet, dass die Anzahl der Anfragen, die ein Server innerhalb eines bestimmten Zeitraums annehmen kann, begrenzt ist. Obwohl dies ein nützliches Element der DDoS-Abwehr ist, wird es bei größeren, komplexeren Angriffen nicht funktionieren.

Wenn es darum geht, größere DDoS-Angriffe zu verhindern, kommt der Einsatz einer Web Application Firewall (WAF) und der Anycast-Netzwerkdiffusion ins Spiel. Anycast ist eine Netzwerkadressierungs- und Routing-Methode, bei der eine einzelne Zieladresse über mehrere Routing-Pfade zu zwei oder mehr Endpunktzielen verfügt. Im Wesentlichen verteilt das Anycast-Netzwerk den Datenverkehr auf eine Vielzahl von Servern, die wiederum den Datenverkehr zerstreuen, bevor er Ihren Server erreicht.

Eine WAF kann auch dazu beitragen, den sehr häufigen Layer-7-Angriff abzuschwächen, indem sie eine Reihe von Regeln zwischen dem Ursprungsserver und dem Internet platziert, die als Gatekeeper fungieren und den Server vor bösartigem Datenverkehr schützen.

Nun kann die manuelle Implementierung und Konfiguration der oben genannten Maßnahmen eine entmutigende Aufgabe sein, insbesondere wenn man bedenkt, dass die von uns behandelten Lösungen weit von den fortschrittlicheren verfügbaren Sicherheitsvorkehrungen entfernt sind. Aber entmutigend bedeutet nicht, dass es unmöglich ist. Das Einrichten einer WAF auf Ihrem Server umfasst unter anderem die Installation und Konfiguration von OWASP. Dies ist ein relativ unkomplizierter Prozess, bei dem mod_security auf Ihrem Linux-Server installiert und ein Repo auf GitHub verwendet wird, um ein paar einfache Klone zu erstellen.

Das Einrichten eines Anycast-Netzwerks ist etwas mühsamer und mit höheren Kosten verbunden. Um ein Anycast-Netzwerk einzurichten, müssen Sie zunächst regionale und globale Server oder Knoten in mehreren Rechenzentren einrichten. Sobald Sie diese Server eingerichtet haben, müssen Sie Ihr Netzwerk so konfigurieren, dass die eingehenden Anfragen so weitergeleitet werden, dass sie mithilfe einer bestimmten Priorisierungsmethode auf Ihre Server verteilt werden.

So stoppen Sie einen DDoS-Angriff

DDoS-Schutz

Wie kann man also einen DDoS-Angriff stoppen? Sie können eine WAF implementieren, ein Anycast-Netzwerk einrichten und nutzen und selbst einen Servercluster verwalten. Oder Sie können eine vorhandene, leistungsstarke Sicherheitslösung wie Global Edge Security zusätzlich zu den DDoS-Abwehrtools verwenden, die in den standardmäßig verwalteten WordPress-Hostingplänen von WP Engine enthalten sind. Die Sicherheit Ihrer Website könnte von unserem DDoS-Schutzdienst profitieren.

Wenn Sie sich für eine Cyberabwehr der Enterprise-Klasse entscheiden, die speziell zum Schutz Ihrer WordPress-Site(s) entwickelt wurde, können Sie sich auf Ihr Geschäft konzentrieren, statt sich mit der Wartung von Anycast-Netzwerken, WAF-Regelsätzen oder den Sicherheitspatches, die Sie auf Ihrer Website anwenden müssen, zu befassen Server. Um von diesen Vorteilen zu profitieren, sollten Sie über eine Investition in den Schutz vor DDoS-Angriffen nachdenken.
