SAP is a complex and ever changing system, whether because of changes introduced to your SAP implementation to better suit your business or through the application of Security Notes (Patches) to ensure that newly disclosed vulnerabilities are mitigated.
In order to provide a predictable and scheduled flow of vulnerability mitigation information and security patches, SAP releases the major part of their latest Security Notes information on the second Tuesday of every month. Due to this regular disclosure of new security issues that could potentially weaken the security of SAP systems within an organization, it’s highly recommended to carry out periodic assessments on a monthly basis at least.

The goal of this is to provide SAP clients with detailed information about the newly released notes and vulnerabilities affecting their SAP systems and help guide their testing of these systems within their organization.
