Internet Security for Beginners (openHPI)

Internet Security for Beginners (openHPI)

Hackers manage again and again to steal passwords, to access sensitive enterprise and user data, and, in the worst case scenario, to even paralyze entire companies. The Internet offers various possibilities to its users, but, at the same time, it harbors dangers and vulnerable points of attack, which many people are not even aware of. In this openHPI course you will learn the basics of Internet security.

Why is the Internet insecure by nature of its design? What are the weak spots of the Internet and how are they exploited by cybercriminals? We want to answer these questions and a lot more in this course. Additionally, we will advise you on how to protect yourself from such cyberattacks.

Course contents

Week 1:
We will explain the basic terms vulnerability, attack, and incident in the first week. Furthermore, we will elaborate on attackers, their motives and their origins.
Week 2:
In week 2, we will explain the idea and the concept of digital Identities and passwords. We will discuss the digital footprint, the feasibility to (easily) crack passwords and guidelines to chose a secure password.
Week 3:
In this week we will discuss several issues about malware. We will cover different types, such as, viruses, worms, and trojans, talk about botnets and mention some countermeasures.
Week 4:
In week 4, we will talk about dangers and risks that arise through the usage of open routes in the Internet. Therefore, we will discuss how attacks can capture messages and eavesdrop or even manipulate and compromise connections. Furthermore, some security mechanisms for those open communication channels, such as firewalls and encryption are illustrated.
Week 5:
In the 5th week, we will take a closer look at the general topic encryption. Therefore, we explain different cryptographic algorithms and how they can be used for various purposes.
Week 6:
In this week we will talk about several topics related to data privacy and private sphere in the digital world. Starting at the Internet as one big eco-system we will also cover privacy in the context of smartphones and wearables, the Internet-of-things or cloud computing, for example.
Final Exam:
Show what you have learned during the course by taking the final exam and qualify for a certificate.

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.
