On March 6, Microsoft pointed out vulnerabilities in the Microsoft Exchange software. IONOS had already learned of the vulnerability on March 3 and immediately applied updates provided by Microsoft to all Exchange systems it operated itself in order to eliminate the vulnerabilities. IONOS systems were not affected by the attack wave.
In any system based on user accounts, Identity and Access Management has a role to play. So does every application use IAM? How important are Identity and Access Management systems when it comes to corporate compliance? And what features do these systems offer?
There are billions of stolen logins circulating on the dark web today. Hackers use these combinations of logins and passwords to break into user accounts and steal sensitive data using a technique known as “credential stuffing”. To protect your data, you need to know how credential stuffing works and what countermeasures you can take to protect yourself.
Ethical hacking has been booming worldwide for several years. A growing number of companies voluntarily choose to be hacked and commission skilled IT professionals to target them by attacking their own infrastructure. Real stress tests under real conditions are intended to reveal weaknesses in their systems and prevent illegal hack attacks that could have dire consequences. The procedure is also...
Hash functions are used in many areas of computer science. They generate hash values that represent digital information in a consistent manner according to defined parameters. They provide additional security (using encryption) during data transmission and allow data to be accessed more quickly. We explain what hash functions are, how they are used and provide some examples.
Data protection is very important, especially when it comes to high-security branches like the government and the military. Users in most organizations only have access to the data they need to do their job, and when it comes to highly sensitive data, it’s important to have a system that’s as tamper-proof as possible. That’s where Mandatory Access Control comes in. Keep reading to find out how...
Organizations restrict access permissions in systems to protect sensitive data from unauthorized access and modification. However, assigning access permissions to users individually is a high-maintenance and error-prone process. In the case of role-based access control (RBAC), permissions are assigned based on previously assigned roles. Here, we explain how role-based access control works.
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.
Being constantly faced with headlines about stolen passwords, it’s understandable that many users are concerned. Your best bet is to make your passwords as complicated as possible and have them consist of many different types of characters. But even this won’t help if it’s the actual log-in area that isn’t secure enough. Even today, attackers are still successful with the notorious and simple...
DNS spoofing involves tampering with DNS name resolution. This kind of attack poses a serious threat to internet users. Here you will learn how the different types of attack methods work, which targets attackers go after, and what you can do to effectively protect yourself.
