The traditional data center could be significantly streamlined by migrating to a hyper-converged system. By eliminating the need for highly complex infrastructures and multiple work areas, the company’s IT department could function more efficiently, dynamically, and cost-effectively. This is made possible using preconfigured standard hardware and a complete virtualisation of the IT infrastructure....
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...
When it comes to network security, administrators focus primarily on attacks from the internet. But often times, the danger lurks in the internal network. If the LAN turns out to be a blind spot in the security IT, then internal attackers have an easy time. A popular method of attack is ARP spoofing. With this, hackers switch undetected between two communication partners in order to intercept,...
Internet users are constantly the target of cyberattacks. Most attacks are easy to fend off, but a new form of scam has proven to be especially dangerous. Spear phishing messages don’t contain absurd claims or bad spelling. These deceitful messages target specific individuals and look frighteningly real. How do these attacks work?
The most effective system break-ins often happen without a scene. Instead of disrupting central network devices with DDoS attacks or sneaking through onto operating systems with Trojan horse techniques, hackers increasingly try to exploit the human security gap. There are various such methods that fall within the broader category of social engineering: a technique that sees hackers gather publicly...
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...
DDoS attacks are occurring more and more frequently. Among the most insidious are HTTP flood attacks. Disguised as regular users on the website, thousands of complex requests are sent to the server until a system failure occurs. Here you will learn what exactly an HTTP flood attack is, how you can identify them, and how you can protect yourself from them.
If you operate or rent your own server, it is your responsibility to protect it against failures and external access. You can immediately begin to set the foundation for this when configuring the server, if you have the necessary administrative rights. The correct settings can work wonders, especially with encrypted remote connections via SSH protocol, and greatly increase security.
For businesses, a reliable IT infrastructure is just as integral to day-to-day operations as competent management, productive employees, and reasonable working conditions. A server outage is able to paralyse an entire company. Adequate preparation can help prevent some of the most common errors from occurring; unforeseen risks, however, will always remain a factor. In order to be on top of your...
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...
