In order to systematically find security vulnerabilities in custom SAP® developments and to correct errors, Krones AG introduced automated code checks despite of initial doubts. After a two year operating period, the machine and plant manufacturer draws a positive conclusion.Read more
The first article of this series talked about the global deactivation of authorization checks for single authorization objects per transport. A similar risk results from the possibility of deactivating authorization checks transaction-specifically. It is even more difficult to detect an attack if this method is used, as the impact can be limited to one transaction.Read more
An increasing number of companies report on the importance of vulnerability scanners in the IT context. We will go one step further and tell you why it is reasonable to particularly use vulnerability scanners for your SAP® systems.Read more
The news about the KRACK attack is causing quite a fuss in the media. This is not surprising since it effects a Wi-Fi-technology thought to be safe until now. Plus, surely everyone uses this encryption. But what does this vulnerability to WPA2 encryption mean to SAP® customers?Read more
The opinions on the SAP authorization concept diverge widely. Surely, a certain complexity and the related maintenance effort cannot be denied. Yet, the most important requirement, the gapless protection of all read and write accesses within a program, can be realized quite well – at least in theory. In practice, there are several options to circumvent authorization checks.Read more
It's amazing that this vulnerability was published as late as 2012, considering the fact that the SAP gateway is a standard interface for every SAP system. And specifically interfaces should be secured by all means. Eventually it was SAP themselves, which had drawn attention to the SAP Gateway Exploit. One of the most dangerous weaknesses of each SAP system is thus recognized - but still not secured at many SAP customers.
Two independent studies have shown that the awareness regarding SAP security has tightened up over the past 12 months SAP users of the DACH countries as well as the SAP user group United Kingdom and Ireland see the necessity to spring into action and better protect their systems.Read more
If you want to check if the doors of a house are securely locked, it is best to try it yourself. The resident has an advantage over an intruder: he knows all doors and windows which can be used or misused as entry points. The same holds true for SAP systems: a penetration test is far more effective if an external attack (black box pen-testing) is combined with an analysis of possible vulnerabilities from within (white box pen-testing).Read more
It sometimes seems like new trends aren't even that new. This is especially hard to notice, if the trend has even gotten a new new. This is the case with DevOps or DevSecOps if security is being included.Read more
At TRUMPF, an interruption to its SAP system could have serious consequences. This is why the mechanical engineering company, located in southwestern Germany, takes a targeted approach to ensuring seamless system operations. One approach is to use the Virtual Forge CodeProfiler, which identifies risks in custom ABAP code.

Just like in life, small things can have a big impact on SAP development. For example, the quality of the customer’s code naturally depends on several factors, like the correct interception of exceptions, the use of sufficient comments, and making sure that database access does not unnecessarily waste any resources. But if one takes a closer look at customers’ development guidelines, one often finds a passage dictating naming conventions. Applying these naming conventions to all objects is not an easy task though.Read more
No matter if Industry 4.0, SAP HANA, Cloud or Blockchains: if you want to survive on the global market, you cannot afford to shut yourself off to recent IT trends. This is also shown by the relevant offers of SAP. But the progressing digitalization means higher demands on security.Read more
