NNTP - Network News Transfer Protocol

NNTP: What is the Network News Transfer Protocol?

As a global computer network, the Internet provides the perfect foundation for gathering and distributing information. The World Wide Web, the most well-known Internet service, convincingly proves this fact. The older Usenet benefits from the Internet’s global network as well. In order to be able to transfer data, it relies on the unique NNTP, which is the focus of this article.

TCP ports and UDP ports

UDP and TCP ports: A list of the most important ports

Protocols control communication on the Internet. Doors have to be opened so that packages of data can get into systems and come out of them. These ports are an important aspect of the Internet. There are over 65,000 possible UDP and TCP ports, which are broken down into well-known ports, registered ports, and dynamic ports. Which ports are important?

What is ICMP protocol and how does it work?

What is the ICMP?

In the background, numerous protocols ensure that communication and data transmission work in computer networks. As the most prominent representative, the Internet Protocol plays a fundamental role. Without its’ various extensions and additions they would be nowhere near as versatile, as is the case in the current protocol.

DHCP Snooping

DHCP Snooping: More Security for Your Network

DHCP snooping makes a network more secure. There are no two ways about it: DHCP makes network configuration so much easier. This is especially the case in large networks, where devices are constantly changing and the manual assignment of IP addresses is a never-ending task. Yet by using DHCP to simplify the process, you do relinquish controls, and criminals can take advantage of this. By using...

IP Spoofing: Fundamentals and counter-measures

IP Spoofing: Simple manipulation of data packets by attackers

Sending data over networks is one of the most important and highest utilised functions of the modern computer era. But the structure of the necessary TCP/IP connections makes it all too easy for criminals to intercept data packets along their way and either view or alter their contents. One of the most common methods of attack is IP spoofing, which allows DoS and DDoS attacks, among other things...

SCP Secure Copy

SCP (Secure Copy Protocol): What is SCP?

If you are looking to perform an especially secure file transfer between two computers (e.g. uploading data to a web server), there are several options available. One of these options is the Secure Copy Protocol (SCP) which provides authentication and encryption via SSH. In this article, you will learn what this protocol is and how the SCP transfer works.

What is MAC spoofing?

What is MAC spoofing?

MAC spoofing is a method by which unique hardware addresses are masked using a Locally Administered Address (LAA) in the software. MAC spoofing can offer protection for your privacy when using public LAN or WLAN networks, but can also be used for illegal network activities. We explain to you here how MAC spoofing works and which settings in Windows must be accessed in order to change your MAC...

TLS (Transport Layer Security)

TLS: How the Internet is encrypted

Internet security measures have become indispensable these days. Encryption is essential to ensure that unauthorised third parties do not gain access to data or are able to manipulate it. That’s what TLS or Transport Layer Security is for. Here’s what you need to know about this integral element of the modern Internet.

csrss.exe

csrss.exe: What’s behind the Client Server Runtime Process

What is csrss.exe? If you inspect the processes currently running on your Windows system, you’ll inevitably come across the csrss.exe process. Your system can’t run without it because it’s responsible for important tasks such as launching processes. If you suspect that the file might be a virus, it’s a good idea to inspect whether it’s the genuine csrss.exe file. But can you spot the difference?

Headless CMS: What are the benefits?

Get more from your own content with headless CMS

If you want to juggle more than one channel with your content management system, you’ll quickly reach the limits. A classic CMS offers many simplifications, but at the same time is limited with its design options. For this reason, content creators sometimes rely on another solution: a headless CMS. This separates the frontend from the backend so that different websites and mobile apps can be...
