SAP Security Patch Day – February 2023
On February 14th, 2023, SAP released their monthly product patches with significant security implications to their customers. SAP’s product portfolio is extensive and widely used by organizations to process critical business information. As a result, many businesses have established a regular and precise patch cycle, which typically begins with SAP’s Security Patch Day.
To ensure the utmost security, clients manually search for newly released security patches and scan their content. This effort requires sorting and filtering patches by relevance and priority. Once this is done, the implementation can commence. Most of the time, the SAP transaction code SNOTE is used to download and install the patch. However, this process requires expert knowledge and is not comparable to Windows’ automatic update.
Once the patch is installed, it can only be deployed into the development stack. The patch must undergo successful testing in the testing environment before promoting it into the production system. During a specific maintenance window, the critical correction(s) can be implemented into the production system to avoid any disruption to business operations.
The cycle starts again today, as it is the SAP Security Patch Day of February 2023.
