Standard SIEM monitoring is often insufficient to ensure SAP security, because the specific SAP logs and analyses can’t be interpreted and, consequently, attack patterns cannot be identified or recognized. Why this is the case, what companies can do to integrate SAP in their monitoring nonetheless, and why this end-to-end safeguarding can deliver additional benefits – our CTO Ralf Kempf explains it all in an article for it management magazine.
The RFC (Remote Function Call) is the main SAP technology for exchanging data between SAP systems. In addition to standard RFC connections, it is also possible to configure trusted relationships. In our technology tip, find out when you should use trusted system relationships and how you can use them securely.
Seize the opportunity to take your SAP S/4HANA migration to a new level with a cleanly designed, holistically planned security and compliance strategy. After all, having structured plans from the start will reduce the workload in the long term. That’s why you should ultimately see this challenge as an opportunity as well: to improve the security of your SAP systems, streamline your role concepts, and enable use of the new system with all its benefits.
Information just now officially provided as part of the November SAP Patchday describes a new critical vulnerability: The SAP Security Note 2928635 (CVE-2020-6284) is a Cross-Site Scripting vulnerability (XSS) in SAP NetWeaver Knowledge Management. Act now to close the loophole!
Ralf Kempf, CTO SAST SOLUTIONS, and his team have already guided many enterprises through their migration to SAP S/4HANA. He talked about his recipes for success in an interview with Ulrich Parthier, publisher of it management magazine.
Excerpts from the interview are provided below.
There are many methods for assessing the risk potential of SAP landscapes and identifying potential vulnerabilities, so it isn’t always easy to keep track of all the alternatives. Options range from vulnerability scans to audits and penetration tests. But which approach is the right one for identifying vulnerabilities depends entirely on your individual requirements.
In most cases, enterprise networks are infected as a result of human error. Employees click on spoofed links, accidentally reveal their passwords to third parties, or open a file that contains unexpected malware. In attack vectors involving the SAP GUI, employees are often not to blame, because an incorrectly configured SAP system is enough to enable damage to the IT landscape.
It is well known that SAP systems present an attractive target for hackers and manipulators. After all, SAP systems gather all the sensitive company data in one place, making it all the more important to protect them against unauthorized access. In addition to conventional measures for improving SAP security and compliance, this includes extensive anti-virus protection adapted specifically to the requirements of SAP systems.
The Security Audit Log allows users with extensive authorizations to be monitored. This is particularly useful for ensuring compliance with both internal security policies and external legal requirements. The SAP standard tool gives an overview of critical activities relevant to security and logs them.
To secure and encrypt customer networks, SAP offers the SNC (Secure Network Communications) interface with which users can log in to SAP systems without having to enter a user name or password. In the standard system, SAP login credentials are transmitted in clear text. The SNC interface routes calls through the SAP Cryptographic Library, to encrypt all communications between the SAP GUI and the SAP server. This enables secure individual logins for SAP.
