Autonomous cars, intelligent factories and self-regulating supply networks – a dream world for large-scale data-driven projects that will make our lives easier. However, what the cloud model is and how it works is not enough to make these dreams a reality. The challenge of effectively capturing, evaluating and storing mass data requires new data processing concepts. With edge computing, IT...
The attack pattern of a SYN flood attack has been known since the early years of the World Wide Web. Over time, new attack variants and appropriate protective measures have arisen. DDoS attacks with massive data flows originating from botnets are currently the norm. Learn how SYN flood attacks work. We will explain the concepts of these attacks and countermeasures.
Netcat is a true all-rounder in networks. Fault diagnostics, chats, extensive data transfers, and network security all form part of the impressive repertoire offered by the command line tool. But if it ends up in the wrong hands, it can also be misused. IT managers should therefore familiarize themselves with the tool.
In Windows, you can adapt frequently required shutdown routines to your individual needs in many different ways. For this, Windows provides an appropriate tool in the command line, which is also referred to as the prompt – CMD or cmd.exe. We introduce shutdowns via CMD, which can handle efficient, simple, but also more complex shutdown routines.
The ping flood is a type of denial-of-service attack that can affect commercial providers and home users alike. This attack relies on the ICMP protocol and the ping command. In order to unleash a particularly powerful flood, attackers often use a network of bots. Learn how the ping flood works and how you can protect yourself from one.
What is a network? Simply put, one of the most fundamental achievements in IT. Nowadays, most of us can no longer imagine a world without Wi-Fi, cell phones or the Internet. But how exactly do these computer networks work? And what does setting up a network involve? In this article, we’ll explain the most important principles of networks.
Remote access to remote computer systems has always been a part of well-organized networks. Administrators can manage individual users as well as work on the move since a remote connection enables access to company data. One of the first protocols developed specifically for this purpose was Telnet.
Netsh is a versatile command line tool for administrating networks on Windows. Once you’ve learned the syntax and its special structure, you can solve a range of tasks and problems. Get to know the Netsh commands and find out how to administrate Windows networks comfortably, and efficiently via Windows command prompt.
For computer systems to be able to communicate with each other and exchange information, they need common ground, just like humans must share a common language. But computers don’t rely on foreign language lessons, and instead only need the appropriate network protocol to successfully communicate. This provides guidelines and structures for the data transfer, and so plays a decisive role in the...
A stable network is characterized not only by the appropriate hardware structures, but also by a watertight security concept. In addition to back-up solutions and intelligent fail-safe systems, protection against external access attempts is a must. Intrusion detection systems (IDS) and intrusion protection systems (IPS) are an excellent addition to the classic firewall and are therefore a sensible...
