Hi Paul,
I need some advice on whether SAP Security Notes contain hacker and/or virus defences?
SAP releases respective security notes as per the loophole identification. Once you run RSECNOTE you get the list of all applicable notes to your software release.
Applying these notes will help you to remove the vulnerability SAP identified, So yes it contains solution to remove vulnerability.
I'm writing a report and what to confirm whether these notes offer any advice, support or notification of hacking or viruses. Similar to Internet security software I guess.
Could you please elaborate it is not that clear to me.
BR,
