Social engineering – the security gap at ‘layer 8’
What is Social engineering?
  • Security

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...

RAID 1
RAID 1
  • Security

Hardly a storage concept embodies the RAID principle (Redundant Arrays of Independent Disks) as well as RAID 1 in which two or more hard disks are linked to save copies of data for access in case of system failure. Find out more about RAID 1 and why mirroring makes this network so special.

Kerberos
What ist Kerberos authentication and how does it work?
  • Security

What is Kerberos and how does it work? When using unsecure networks, you may expose yourself to cyberattacks. However, a number of security protocols exist that make it difficult for hackers to read sensitive data. Kerberos is a widely used authorization technology based on a trusted third party. Read on to find out how Kerberos works.

ISO 27001
ISO 27001
  • Security

By complying with the ISO 27001 standard, companies can prove they carefully handle information and plan for exceptional circumstances. Public certificates and standards according to the ISO certification create trust among consumers and attest to the company’s secure and tested treatment of data. The certification is performed by an independent institute.

IP Spoofing: Fundamentals and counter-measures
What is IP Spoofing?
  • Security

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...

DKIM (DomainKeys)
What is a DKIM record and how to create a DKIM record?
  • E-Mail security

Fake emails pose a major threat to recipients. At the same time, it’s becoming increasingly difficult to verify the authenticity of emails and sender addresses. One effective method of verifying the sending mail server and checking the authenticity of emails is called DKIM (DomainKeys Identified Mail). What is DKIM and how do you set it up?

Hash table
Hash table | Fast database access to hash values
  • Security

A hash table is created using the hash function. This is a method for reducing digital information in such a way that extensive data sets can be retrieved quickly in internet-based databases. This method also makes it possible to implement sophisticated security features using encryption when transferring data.

Encryption software
Encryption software and tools in comparison
  • Security

A good encryption software keeps your data secure. It enables you to easily protect a folder, hide hard drives, or sync encrypted data to a cloud, for example. Find out more information about recommended encryption tools and what they do, and get an overview of their advantages and disadvantages in our dedicated article.

DRaaS
Disaster Recovery as a Service (DRaaS)
  • Security

Throughout the course of digitization, employees and employers became aware of the importance of backups. The 3-2-1 rule was considered the golden rule - where two redundant copies of each file are kept. As technology continues to evolve, cloud-based solutions are becoming more popular. Thus, Disaster Recovery as a Service has established itself as an important cloud service.

DNS over TLS
DNS over TLS | An improved security concept
  • Security

The Domain Name System has a big security flaw: requests and responses are traditionally sent unencrypted. This provides Internet criminals with an ideal point of attack. Again and again, users are being directed to websites that they actually have no desire to visit. DNS over TLS acts as a deterrent. How does the security concept work?
