Would you give your bank account pin number to a stranger? Certainly not. However, this is essentially just what you are doing if you don’t secure your online banking log-in with a password that can’t be figured out by hackers in a matter of seconds. In order to be able to create and manage all of your passwords in a completely secure way, it is worth making use of a password manager.
In the digital age, we are increasingly resorting to cloud services: At work, people collaborate on projects together in the cloud, and in their free time, they share photos from their last vacation. At the same time, cloud storage is by no means free from security risks. The multi-cloud environments of larger companies, in particular, are becoming a challenge for cloud security. Here, we will [...]
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).
E-mail, instant messaging, or voice-over IP: If you want to communicate over the internet, you should make sure that the data transfer process can be trusted. The same goes for the World Wide Web. With online banking and digital shopping, money transactions are increasingly being carried out online. Popular encryption methods like DES, AES, or RSA should guarantee the security of passwords, credit [...]
When you’re traveling with portable devices, you’ll find public WLAN everywhere, giving you access to the world wide web. Even in residential and work spaces, practical wireless networking is widespread. It’s easy to forget that there’s a risk involved when transferring data using one of these access points. In the following article, we explain the biggest security risks and show you how to make [...]
Sending data over networks is one of the most important and highest utilized 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 [...]
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 [...]
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, [...]
The internet is a playground for cybercriminals and fraudsters – for many, this is an annoying and frightening reality. The threats from unwanted software range from harmless advertising to trojans, which can paralyze complete computer networks. The forms of malicious software or malware are diverse, the countermeasures often very simple. In our article, you can read about how ransomware, spyware, [...]
