Botnets are tricky to spot, but they’re all over the internet and they cause all kinds of damage every day. They lurk inconspicuously in the background and use millions of private computers for malicious purposes. This guide explains how botnets work, how to keep them away, and how you can avoid falling victim to an illegal network.
A firewall provides effective protection against viruses and other malware that attempts to infect your computer. However, it needs to be properly configured to do so. In the following article, you will learn how to do this, how a firewall works, and what its limitations are.
Security gaps in IT infrastructure can risk a company’s reputation or even threaten its survival. Where criminals manage to shut down company networks or gain access to sensitive data, financial and image-related damage becomes a certainty.

DevSecOps is the optimal approach for achieving faster software development, without having to make any cutbacks to security. Security packages are directly integrated into the development process. We’ll explain its pros and cons and clarify the various possibilities for using the system.
SSL/TLS certificates play an increasingly important role in the transmission of sensitive data. They guarantee that data packets reach the desired addressee without any detours. Problems only arise when internet users are deliberately redirected by invalid certificates from dubious certification bodies – a scenario that can be prevented using so-called HTTP public key pinning (HPKP).
Hash functions are used in many areas of computer science. They generate hash values that represent digital information in a consistent manner according to defined parameters. They provide additional security (using encryption) during data transmission and allow data to be accessed more quickly. We explain what hash functions are, how they are used and provide some examples.
