Wir sollen unser Kennwort regelm\u00e4ssig \u00e4nder, am liebsten alle 30 Tage. Doch n\u00fctzten solche Regelungen wirklich etwas?<\/p>\n

Lassen wir uns wirklich jedes mal ein neues Kennwort einfallen?<\/p>\n

Wenn wir jeden Monat unser Kennwort \u00e4ndern, verfallen wir in ein Schema um denn Passwort wechsel zu vereinfachen. Nehmen wir an unser Kennwort ist kLoh4T<\/strong> n\u00e4chsten Monat m\u00fcssen wir unser Kennwort \u00e4ndern. Nun lautet es kLoh5T, kLoh5t, KloH4t<\/strong>, usw..<\/p>\n

Wir werden verleitet das selbe Kennwort nur leicht abzu\u00e4ndern und wieder zu benutzen. Dies birg Gefahren bei Passwort-Attacken. Bei einem Test<\/a> konnten 17% aller Kennw\u00f6rter, welche immer dem selben Schema folgten, nach 5 Versuchen geknackt werden.<\/p>\n

Sollten wir Kennw\u00f6rter also nie \u00e4ndern?<\/p>\n

Nein. Kennw\u00f6rter sollten regelm\u00e4ssig gewechselt werden. Es m\u00fcssen aber gewisse Vorraussetzungen gegeben sein.<\/p>\n

\n
Das neue Kennwort sollte keine Teile des vorhergehenden Kennwort enthalten.<\/li>\n
Kennw\u00f6rter sollten nicht fortlaufend sein (z.B. Test01, Test02, Test03, usw..)<\/li>\n
Die Laufzeit entspricht einem realistischem Zeitrahmen (90 Tage – 120 Tage)<\/li>\n
Nach einem Angriff auf das Netzwerk sollten Kennw\u00f6rter schnellst m\u00f6glich ge\u00e4ndert werden.<\/li>\n<\/ul>\n
