The builds include default settings to apply security by default based on hardening requirements and best practices. The settings are outlined in SAP Note 3250501 – Information on Mandatory Security Parameters & Hardening Requirements for ABAP systems in SAP Enterprise Cloud Services (ECS).
The requirements include recommended settings for security-relevant profile parameters, deleting unused clients, securing standard users, restricting access to password hashes, RFC gateway and message server hardening, deactivating critical ICF services, managing system and client change options, and applying transport layer security. There are over 120 specific requirements across 12 areas that customers must abide by to comply with SAP security standards for RISE solutions.
The Cybersecurity Extension for SAP (CES) performs automated gap assessments to ensure RISE solutions comply with SAP security requirements. The assessments are performed using Compliance Reporting accessed from the CES launchpad.
SAP RISE should be selected from the framework selection screen.
Once the framework is selected, you can select a target system from the available systems in your SAP RISE landscape and click on Execute.
The results are summarized for each requirement and an overall compliance score is calculated for the system.
You can drilldown into each requirement to navigate the detailed findings.
You can click on the > icon for each finding to view further information and create an action plan to manage the remediation of compliance issues.
The report filters can be used to focus on specific requirements or results. For example, you can suppress compliant areas to isolate compliance failures.
Shortcuts can be created and published to the Fiori launchpad for fast access to compliance results.
The shortcuts can be published as custom tiles to existing or new work groups.
Compliance reports can also be scheduled to run on regular intervals. The reports are automatically distributed in PDF or CSV to recipients by email during each run.
The Cybersecurity Extension for SAP is an SAP-certified addon for SAP Solution Manager and SAP Focused Run. An addon version for other SAP NetWeaver AS ABAP systems such as SAP GRC is expected in Q4 this year.

Usage rights for SAP Solution Manager are included in SAP support and maintenance agreements for on-premise SAP solutions. The rights include database licenses for SAP HANA and ASE. Customers with Enterprise Support agreements have usage rights for all functional areas of Solution Manager, whereas customers with Standard Support agreements have restricted rights that include commonly used areas such as Change and Release Management (ChaRM), System Recommendations, and System Monitoring, but excludes areas such as Custom Code Management and Business Process Analytics.
SAP Cloud ALM is an alternative Application Lifecycle Management (ALM) solution that is provided to SAP customers with active cloud services. It can be used for both cloud and on-premise SAP solutions. Enterprise Support customers have usage rights for Cloud ALM but customers with cloud services and no on-premise solution supported by SAP do not have usage rights for Solution Manager.
There is currently no feature parity between Cloud ALM and Solution Manager. In other words, Cloud ALM does not support the same scenarios as Solution Manager. Since many customers require ALM functions that are not provided by Cloud ALM, SAP provides cloud-only customers with the option to subscribe to SAP Solution Manager, Private Cloud Edition (PCE).
Solution Manager PCE is the successor to SAP Solution Manager for SAP S/4HANA Cloud and like its predecessor, it is available in two versions: Project Documentation and Full. The main difference between the two versions is that the project documentation version is deployed as a single-system landscape, whereas the full version is deployed as a dual-system landscape, similar to on-premise installations. The full version is required to support the deployment of agents to managed systems.
Cloud-only customers can order the full version of SolMan PCE from SAP Enterprise Cloud Services (ECS) using SKU 8014172 providing they are using SAP S/4HANA or ERP on RISE. It is provisioned by SAP ECS within 30-40 days and includes SAP HANA.
The Cybersecurity Extension for SAP can be deployed to both on-premise and cloud installations of SAP Solution Manager. This includes SolMan PCE for RISE customers. Layer Seven Security provides a fully managed service for RISE customers that includes setup and maintenance of SolMan PCE.

SAP RISE is a cloud-based service offering from SAP that includes the private edition of SAP S/4HANA Cloud at the core. As part of the offering, SAP maintains privately-managed, single-tenanted accounts for each customer with hyperscale providers including AWS, Azure and GCP. The accounts are fully managed by SAP. Therefore, SAP acts as a cloud service provider and the customer is essentially a consumer of an SAP cloud service.
SAP customers are responsible for most aspects of security for on-premise deployments or cloud deployments managed directly with hyperscale providers. However, SAP RISE divides the responsibilities between SAP and customers.
As the cloud service provider, SAP assumes many of the responsibilities for security that would otherwise lay with the customer. This includes security at the hyperscaler and network level, as well as security for databases and servers, including operating systems for SAP servers.
Customers are responsible for the application and data layer. However, the responsibility for these areas can also be shared with SAP through optional Cloud Application Services (CAS) that extend the services delivered through SAP RISE. For example, SAP can assume the responsibility for identifying, analyzing, and implementing required security notes. However, this requires an additional CAS package that is not included in standard RISE services. If the customer does not obtain the package, the responsibility for analyzing and selecting notes for implementation lays with the customer. Once selected, the customer can create a service request for SAP to apply the notes.
The security of custom code is also the responsibility of each customer. Customers are encouraged to analyze custom code and remove obsolete, redundant and duplicate code to comply with SAP’s Clean Core principle. The remaining custom developments can be adapted and migrated to systems maintained by SAP Enterprise Cloud Services. However, customers are responsible for ensuring that the developments are secure and do not contain code-level vulnerabilities. RISE customers can secure custom SAP programs and applications using the SAP-certified Cybersecurity Extension for SAP (CES). CES supports the automated detection of code vulnerabilities in ABAP and UI5 applications. It can be used to support S/4HANA migrations and on-going development and maintenance activities for custom applications.
With the exception of SAP HANA, access control is also the responsibility of customers. This includes managing end user permissions and administrative privileges. Customers can opt-in for optional CAS packages that provide SAP managed services for this area. The Cybersecurity Extension for SAP can be used to monitor access privileges for systems in SAP RISE including segregation of duties violations and access to critical roles, profiles, transactions and authorizations at both the functional and technical level. This includes S/4HANA and supporting systems.
Security hardening is applied by SAP through standard builds used for each ABAP system. The builds include mandatory security settings documented in SAP Note 3250501. This includes areas such as security-relevant profile parameters, securing standard users, deleting unused clients, deactivating vulnerable ICF services, system and client change options, and hardening for the RFC gateway and message server. The settings can be overridden by customers. Therefore, it is important to automate monitoring for compliance with the hardening requirements. This can be performed using the Cybersecurity Extension for SAP. Compliance Reporting in CES will automatically identify compliance gaps for SAP systems against the requirements of SAP Enterprise Cloud Services (ECS) in Note 3250501.
The final area that customers are responsible for is logging and monitoring. SAP provides customers with access to application logs. Customers can request access to OS, DB and network logs. This is provisioned using a premium offering called LogServe. The application and infrastructure logs can be integrated with SIEM solutions to automate threat detection and response. Alternatively, customers can pay for SAP Enterprise Threat Detection (ETD), cloud edition, or opt for a 24/7 or 8/5 managed service from SAP based on ETD. Neither option is included in standard RISE services.
The cloud edition of ETD includes less than 50 patterns for detecting Indicators of Compromise (IOC) in SAP solutions. The Cybersecurity Extension for SAP provides more than 900 patterns to detects IOCs in SAP systems, including patterns for databases, operating systems, and standalone components such as the SAProuter and Web Dispatcher.
Overall, SAP RISE does not delegate the responsibility for security patching, secure development, access control, hardening, and logging and monitoring from customers to SAP. This is possible for some areas but only through the addition of optional packages that are not included in standard RISE services. Customer and SAP responsibilities are detailed in a comprehensive matrix provided by SAP ECS for more than 1000 tasks. The matrix is a reference for standard, optional, and additional services, excluded tasks, and services available through available CAS packages that are subject to additional service fees. Note that the matrix is subject to change by SAP.
Hot news note 3340576 patches a critical missing authorization check in the SAP Common Cryptographic Library (CommonCryptoLib) that could enable attackers to escalate privileges. CommonCryptoLib is installed in multiple SAP products including SAP NetWeaver AS ABAP, SAP NetWeaver AS Java and ABAP Platform of S/4HANA on-premise, as well as SAP HANA Database, SAP Web Dispatcher, and SAP Host Agent. The installation of CommonCryptoLib 8.5.50 or higher in impacted products is recommended to address the vulnerability. This can be performed by upgrading the relevant software components to the recommended versions detailed in the note.
Note 3333426 was updated for a Server-Side Request Forgery (SSRF) in the GRMG Heartbeat application of SAP NetWeaver AS Java. The vulnerability could lead to information disclosure that could be used to perform further attacks against AS Java. The update impacts support packs 25 and 26 for the software component LM-CORE.
Notes 3324732 and 3371873 address a log injection vulnerability in the Log Viewer of AS Java. The support package patches specified in the note implement encoding and validation for user input to address the vulnerability in the impacted components.
Notes 3372991 and 3357154 patch Cross-Site Scripting (XSS) and missing XML validation vulnerabilities in SAP BusinessObjects and SAP PowerDesigner Client, respectively.
