Sicherheit im Internet (openHPI)

Sicherheit im Internet (openHPI)

Hackern gelingt es immer wieder, Passwörter zu stehlen, auf sensible Firmen- und Userdaten zuzugreifen und somit schlimmstenfalls ganze Unternehmen lahmzulegen. So vielfältig die Möglichkeiten sind, die das Internet seinen Nutzern bietet, so vielfältig sind auch die Angriffspunkte und potenziellen Gefahren, die vom Internet ausgehen und vielen Menschen noch nicht richtig bewusst sind. In diesem openHPI-Kurs lernen Sie die Grundbegriffe der Internetsicherheit kennen. Warum ist das Internet in seinem Grunddesign unsicher? Welches sind die Schwachstellen des Internets und wie werden diese von Cyberkriminellen ausgenutzt? Diese Fragen werden unter anderem in diesem Kurs beantwortet. Gleichzeitig erhalten Sie einige Tipps, wie Sie sich vor solchen Angriffen schützen können.

Course contents

Woche 1:
Wir erklären in der ersten Woche Grundbegriffe, wie z.B. "Schwachstelle", "Angriff" oder "Sicherheitszwischenfall" und erläutern, wer Angreifer im Internet sind, was sie tun und welche Motive dabei zu Grunde liegen können.
Woche 2:
In Woche 2 beschäftigt sich der Kurs mit digitalen Identitäten und Passwörtern: was ist mein digitales Ich, wie (leicht) können Passwörter geknackt werden und wie wählt man ein sicheres Passwort?
Woche 3:
In Woche 3 geht es um Malware (Schadsoftware) - also Viren, Würmer und Trojaner sowie deren Zusammenhang mit den sogenannten Botnets.
Woche 4:
In dieser Woche geht es um Gefahren, die im offenen Internet durch die unsicheren Transportwege drohen: wie können Angreifer Nachrichten abhören oder sich sogar in Verbindungen einklinken und die Kommunikation manipulieren? Außerdem geht es in dieser Woche um Schutzmaßnahmen wie Firewalls und Verschlüsselung für die unsicheren Kommunikationskanäle.
Woche 5:
Das schon oft genannte Thema Verschlüsselung wird in den Woche 5 ausführlich erläutert: der Kurs erklärt den konzeptionellen Unterbau der Verschlüsselungsverfahren und wie diese in der Praxis eingesetzt werden.
Woche 6:
In Woche 6 dreht es sich um die Gefahren und Risiken, die uns in einer immer stärker digitalisierten Welt drohen. Wie wirken sich Trends wie Smart Home oder Connected Fitness auf unsere Privatsphäre aus?
Abschlussprüfung:
Zeigen Sie Ihr erworbenes Wissen in der abschließenden Prüfung und qualifizieren Sie sich für Ihr Zertifikat.

Digital Identities (openHPI)

The average Internet user has more than 25 Internet accounts, which are created for a wide variety of purposes. Besides accounts for e-mail services or social networks, users need access to learning platforms or online shopping services. Each of these internet accounts represents an individual digital identity. Each of these identities in turn contains a wide variety of personal information. In addition to information used to authenticate a user, such as an e-mail address and password, other services require very personal and sensitive data, such as bank details for payment and the place of residence for the subsequent delivery of an order.
