Digitally signed SAP notes

In the previous blog on SAP security notes you will see that security notes popup around “Digitally signed SAP notes”.

This blog will explain more on how to implement this.

Questions that will be answered in this blog are:

  • Why switch over to the new way?
  • How to implement the feature to download digitally signed SAP notes?
  • How to make the relevant settings?
  • Where to find more information?

Why switch over to the new way?

SAP keeps improving their security in all ways. Including OSS notes. There is no direct benefit. After downloading the OSS notes, the handling is identical for old and new way.

Switching over from current way of working to digitally signed SAP notes can be done any time.

SAP has announced the following: "Post January 1, 2020, the download and upload process will stop working unless Note Assistant (SNOTE transaction) is enabled in ABAP systems to work with digitally signed SAP Notes".

How to implement digitally signed SAP notes?

There are 2 basic ways to implement (you have to do only one):

  1. Apply OSS notes 2508268, 2408073 and 2546220.
  2. Apply TCI based OSS note  2576306, which contains all the notes (and manual work) in the notes mentioned in point 1. Your system needs to be able to handle TCI based OSS notes (see this blog on how to do this).

Settings after implementation

If you have done the TCI based import a new customizing node is available:

The second one (direct program in SE38 is called RCWB_UNSIGNED_NOTE_CONFIG) is to allow only digitally signed SAP notes:

How to validate if the notes now are digitally signed?

To see if all is ok, download and implement a new OSS note. In the note log you can now see the digital signature download in the note log (in nice German words):
