\"SR820<\/h4>\n

Ein Kumpel hat mich danach gefragt, also m\u00f6chte ich es f\u00fcr alle aufschl\u00fcsseln. Es bedeutet im Grunde CPE-Router-Authentifizierungssicherheit.<\/p>\n

Was ist CPE-Router<\/a>?<\/h2>\n

CPE = Customer Premises Equipment (Kundenendger\u00e4te), was nur eine hochtrabende Bezeichnung f\u00fcr kundenseitige Ger\u00e4te ist - Dinge wie Router, Modems und drahtlose APs, die wir zu Hause verwenden. Diese Ger\u00e4te sind die erste Verteidigungslinie f\u00fcr die Netzwerksicherheit, im Grunde wie Ihre Haust\u00fcr - wenn diese T\u00fcr nicht stabil ist, sind alle anderen Verteidigungsma\u00dfnahmen nutzlos.<\/p>\n

Wovor sch\u00fctzt die Authentifizierungssicherheit?<\/h2>\n

Die Hauptbedrohung f\u00fcr CPE-Ger\u00e4te besteht heute darin, dass die Authentifizierungsmechanismen zu schwach sind:**<\/p>\n

    \n
  • Standard-Passw\u00f6rter: Viele Ger\u00e4te werden mit schwachen Passw\u00f6rtern wie admin\/admin ausgeliefert - absolutes Noob-Zeug<\/li>\n
  • F\u00e4lschung der MAC-Adresse: Einige Ger\u00e4te verlassen sich nur auf die MAC-Adressen-Authentifizierung, aber dieser Mist hat ein festes Format und kann leicht gef\u00e4lscht werden: Die Verwendung von festcodierten Schl\u00fcsseln, kurzen Passw\u00f6rtern oder selbstsignierten Zertifikaten ist im Grunde genommen eine Art Kommando\u00fcbernahme Was passiert, wenn Sie ausspioniert werden?<\/li>\n<\/ul>\n

    Sobald die Authentifizierung verletzt wird, hat dies schwerwiegende Folgen:<\/p>\n

      \n
    • Pers\u00f6nliche Daten gehen verloren: Name, Geburtstag, Adresse, Telefon, E-Mail, Ausweisnummern - alles ist getoastet<\/li>\n
    • Angriffe auf die Netzinfrastruktur: Hacker k\u00f6nnen mit legitimen Anmeldedaten tief in die Backend-Systeme von Internetanbietern eindringen Dienstunterbrechungen: Malware kann Netzwerkausf\u00e4lle verursachen Wie kann man die Sicherheit erh\u00f6hen?<\/li>\n<\/ul>\n

      Praktische Abh\u00e4rtungsmethoden:1. starke Passwortpolitik Mindestens 12 Zeichen mit gemischter Gro\u00df- und Kleinschreibung + Zahlen + Symbole. Verwenden Sie keine hirnlosen Passw\u00f6rter wie Geburtstage oder Telefonnummern.2. Verschl\u00fcsselungs-Upgrades<\/p>\n

        \n
      • Unterst\u00fctzung von TLS 1.2 oder 1.3 - Schluss mit dem alten SSL-M\u00fcll Drahtlose Ger\u00e4te m\u00fcssen WPA2 oder WPA3 verwenden - WEP und das alte WPA wurden komplett geknackt Netzwerksegmentierung** Verwenden Sie VLANs, um verschiedene Ger\u00e4te zu isolieren. Legen Sie IoT-Ger\u00e4te in ein separates Netzwerksegment - lassen Sie nicht zu, dass sich Ihre intelligente Toilette mit Ihrem Computernetzwerk verbindet Unn\u00f6tige Dienste deaktivieren** Schalten Sie alle ungenutzten Ports und Dienste ab. Jeder offene Port ist ein potenzieller Einstiegspunkt<\/li>\n<\/ul>\n

        5. Regelm\u00e4\u00dfige Firmware-Updates Installieren Sie die Sicherheitspatches der Hersteller umgehend. Seien Sie dabei nicht faul ENSHANG ZusammenfassungBei der Sicherheit der CPE-Authentifizierung geht es im Grunde darum, Ihr Netzwerk-Gateway zu st\u00e4rken. Bei der heutigen zunehmend komplexen Netzwerkumgebung und den \u00fcberall vorhandenen IoT-Ger\u00e4ten ist Ihr gesamtes internes Netzwerk gef\u00e4hrdet, wenn Ihr Router nicht solide gesch\u00fctzt ist.Liebe Forumsmitglieder, denken Sie daran: Mit der Sicherheit ist nicht zu spa\u00dfen, und bei der Konfiguration ist Vorsicht geboten. Seien Sie nicht faul mit Standardkonfigurationen - h\u00e4rten Sie, was geh\u00e4rtet werden muss!<\/p>","protected":false},"excerpt":{"rendered":"
