An Apache web server is a cross-platform free open-source software whose task is to establish a connection between a server with the stored web pages and the browsers of the Internet users. An Apache server can process several HTTP requests at the same time and in this way provide web pages for several users at the same time. In addition to retrieving web pages, the Apache web server can allow users to download files, such as audio files, movie files or PDF files. In addition, extensions or modules, such as password authentication and digital certificates, are provided to extend the functionality of the server.

HAProxy is a load balancer that can be connected upstream of several servers (e.g. web or mail servers) to take over certain previously configured processes. One of the biggest advantages of HAProxy is its stability and speed. Various tasks that would otherwise have to be taken over by the web server can be upstreamed to it. For example, this application can intercept requests that are harmful to the web server or avoid overloading the web server by excluding incoming requests.

Kerberos is a network protocol that is mainly used in open and insecure networks. This protocol is used for authentication and authorisation of users or systems. Kerberos supports single sign-on, so that a user only has to log on once to a central Key Distribution Centre (KDC) and can then use all available network services without any further interaction with the user. With Kerberos, mutual authentication takes place. Both user and server verify each other's identity. The KDC uses symmetric encryption and can authenticate a user for multiple services. In addition to encrypting secret data, Kerberos prevents eavesdropping or falsification of the keys or data.
