Automating SAP Audits with Solution Manager

Layer Seven on April 28, 2020

According to IDC, 80% of ERP applications are audited at least once every 12 months. Driven by regulatory requirements, audits can drain valuable resources from projects targeted at business growth. They can also lead to audit fatigue and undermine relationships between IT and audit stakeholders.

Compliance Reporting in SAP Solution Manager enables organizations to automate audits for SAP systems and reallocate resources to projects and audits focused on other organizational goals. The continuous monitoring powered by the application also enables auditors to identify compliance gaps immediately rather than at the end of a reporting period. This can reduce regulatory risk by providing owners with more time to remediate control gaps.

Compliance Reporting is accessed from the Fiori launchpad in SAP Solution Manager. Results are automatically updated by daily scheduled scans.

Compliance frameworks and systems are selected in the report filter. There are optional filters to select specific control requirements and systems based on environment or priority. Reports can also be filtered to include or exclude controls based on risk rating and compliance result.

Compliance Reporting currently supports the frameworks below. This includes CIS, IT-SOX, NIST and PCI-DSS. Support for additional frameworks including GDPR and NERC CIP is expected at the end of Q2 2020. Customers can import custom frameworks to automate auditing for internal security policies and other requirements.

Results for applications and databases are reported in separate columns. The report provides an overall compliance score based on the selected framework and systems. Results are summarized for each requirement.

Users can drilldown into each requirement to review the results for specific controls. Control ratings and descriptions are included in the report to support analysis.

Reports can be exported to CSV or PDF. The Report Detail option specifies whether results are exported at the Requirement, Control or Description level.

64% of ERP Systems Have Experienced Security Breaches Between 2017-19

Layer Seven on October 31, 2019

According to the findings of a recent independent survey of 430 IT decision makers, 64 percent of ERP deployments have experienced security breaches in the past 24 months. The findings are published in the report ERP Security: The Reality of Business Application Protection. In the words of the IDC, “ERP applications such as SAP can be foundational for businesses. A breach of such critical ERP applications can lead to unexpected downtime, increased compliance risk, diminished brand confidence and project delays…..Cyber miscreants seem to be indiscriminate when it comes to ERP systems, having an appetite for all types of data, which, if in the wrong hands, could be detrimental to the business in terms of revenue and reputation.”

The survey revealed that of the 64% of organizations that reported security breaches in ERP systems, the majority included the compromise of sensitive data including sales data in 50% of cases, as well as HR data (45%), customer data (41%), financial data (34%) and intellectual property (36%).

The survey also revealed the following:

The estimated cost of downtimes in ERP applications is $50,000 or more per hour at almost two thirds of organizations

62% of ERP systems may have critical vulnerabilities
74% of ERP applications are accessible from the Internet
56% of executives are concerned or very concerned about moving ERP applications to the cloud

According to the former Chairman of the Global Board of the Institute of Internal Auditors (IIA), “The findings of this independent survey should raise questions at the Board level about the adequacy of internal controls to prevent cyber attacks and the level of auditing taking place. The lack of these controls is one way for cyber insurance companies to deny claims….The information compromised most often according to this research is the highest regulated in today’s business ecosystem. Most concerning is the popularity of sales, financial data and PII, all of which should raise flags about the possibility of insider trading, collusion and fraud.”

SAP ERP installations can be protected against cyber attack using the Cybersecurity Extension for SAP Solution Manager. The extension implements automated vulnerability and patch management, and security incident detection and response for SAP systems, without requiring additional hardware or agents.

10KBLAZE: Secure Your Systems with SAP Solution Manager

Layer Seven on May 13, 2019

On May 2, the Department of Homeland Security issued an alert for SAP customers in response to the disclosure of new exploits targeting vulnerable SAP components. According to some reports, the so-called 10KBLAZE exploits could impact 90% of SAP installations worldwide. The exploits target misconfigurations in the gateway server and message server installed in most SAP systems including S/4HANA, ERP and CRM. The successful execution of the exploits could enable attackers to exfiltrate or modify data and provoke a denial of service without authentication. In other words, attackers can completely compromise target SAP systems without any user credentials.

The new exploits target known vulnerabilities addressed by notes and advisories released by SAP since 2005. Note 821875 details measures to secure the message server, including restricting external access, separating internal and external communications, and maintaining secure access control lists. The profile parameter ms/monitor should be set to 0 to prevent external programs such as msmon from administering the message server at the operating system level. Access to transaction SMMS should also be restricted since the setting can be changed dynamically using the Message Server Monitor within the application server. A separate port for internal communication between application servers should be defined using parameter rdisp/msserv_internal. This will prevent external clients from intercepting or rerouting internal message server communications. The port should not be exposed to clients or intranets. Finally, the parameter ms/acl_info should specify the file containing a restrictive access control list of hosts, domains, IP addresses or subnets for application servers permitted to log on with the message server.

ACLs should also be defined for the gateway server to control access to starting external programs. This can be performed using the gateway security file sec_info. The correct syntax for the file depends on the kernel level. For kernel 7.20 and higher, the setting USER-HOST=LOCAL is recommended to protect against 10KBLAZE exploits. This will allow connections from the same server instance. The setting USER-HOST=INTERNAL could be vulnerable but is required for SID clusters. For detailed guidance, refer to Note 1408081. The ACLs should be supported by the setting gw/acl_mode to 1. This parameter defines the behavior of the gateway server if sec_info does not exist.

Since some 10KBLAZE exploits are targeted at modifying or redirecting data packets, enabling SNC to authenticate and encrypt client-server communications is recommended.

SAP systems vulnerable to 10KBLAZE exploits can be discovered using SAP Solution Manager. The Cybersecurity Extension for SAP Solution Manager automatically monitors security settings for the message server and gateway server including profile parameter settings, access control lists and users with critical transactions such as SMMS. The extension also monitors message and gateway logs for external monitor commands, successful and unsuccessful program starts, and other events. Alerts are triggered by the extension for suspected exploits.

The example below illustrates how you can discover insecure sec_info entries that could expose systems to 10KBLAZE exploits.

Click on Vulnerability Report in the Fiori Launchpad.

Filter by ABAP systems, select the check-box for the target system and click on Display.

Filter for vulnerabilities in open status within the area of RFC Security. Click on the check for starting of external programs.

Review the details and recommendation. Click on the linked SAP Notes and SAP Help.

Click on Additional Information to review the insecure entries in the sec_info ACL.

Focus on entries with the setting USER-HOST=internal.

Click on the download icon to export the current settings.

If required, add comments in the Comment section.

The finding for the system will be automatically removed from the report once the sec_info entries are updated. However, you can manually change the status using the Change Status option. Note that status changes are tracked in the extension.

You can also assign responsibility for remediating the finding to specific groups using the Change Owner option.

Securing Administrative Access in SAP AS Java

Layer Seven on April 25, 2019

The misuse of administrative privileges is a common method used by attackers to compromise applications and propagate attacks to connected systems. The elevated privileges granted to administrative accounts are a prized target for attackers and provide a fast path to accessing or modifying sensitive data, programs and system settings.

User privileges for Java applications are administered through the User Management Engine (UME) in the SAP NetWeaver Application Server for Java (AS Java). The UME is the default user store for AS Java and can be configured to use LDAP directories, AS ABAP, or the system database of AS Java as the data source for user-related data.

UME permissions granted to users can include administrative actions such as Manage_All, Manage_Roles, Manage_Users, Manage_User_Passwords, and other privileged functions. Administrative actions are bundled into roles and granted to users organized into user groups. Standard user groups include the Administrator group, as well as groups such as SAP_J2EE_ADMIN and SAP_SLD_ADMINISTRATOR. The latter includes users with administrative access to the System Landscape Directory. Standard roles include Super Admin and, for Enterprise Portals running on AS Java, Portal System Admin, Portal User Admin and Portal Content Admin.

Access to administrative roles and rights in AS Java should be granted to required users only, based on the principle of least privilege. Users with administrative privileges in AS Java systems can be detected using the Cybersecurity Extension for SAP Solution Manager. The results are displayed in security reports and dashboards. Alerts are also triggered by the extension for new users granted privileged roles and actions for possible privilege escalations. The extension also detects users with administrative rights in ABAP and HANA platforms, as well as SAP-compatible databases including IBM, Microsoft, Oracle and Sybase.

How to Comply with the DHS Recommendations for Securing SAP Systems from Cyber Attacks

Layer Seven on October 16, 2018

In response to the dramatic rise of cyber attacks targeting ERP applications, the United States Department of Homeland Security (DHS) issued a warning earlier this year that encouraged organizations to respond to the risks targeted at their business applications by implementing specific measures to secure, patch and monitor SAP systems. The measures included scanning for vulnerabilities and missing security patches, managing SAP interfaces, and monitoring user behaviour, indicators of compromise, and compliance against security baselines for systems.

This article discusses how you can leverage SAP Solution Manager to comply with the DHS recommendations. Solution Manager is installed and available in most SAP landscapes and includes diagnostics and monitoring applications to support cybersecurity. The specific applications are outlined below against each of the DHS recommendations.

1. Scan systems for all known vulnerabilities, such as missing security patches and dangerous system configurations.

Configuration Validation in Solution Manager can perform automatic daily scans of SAP systems against security benchmarks to identify misconfigurations that could expose systems to cyber threats. The scans are performed against snapshots of systems stored in the Configuration and Change Database (CCDB). The results of the scans are stored in an internal Business Warehouse (BW). Service Level Reports and Security Dashboards connect to BW using BEx queries to read the results of the security scans and report the findings.

System Recommendations (SysRec) in Solution Manager connects directly to SAP Support to discover missing security patches. SysRec also connects to each system in an SAP landscape to determine the current patch level. It reads the system information in the Landscape and Management Database (LMDB) to identify installed software components and versions. SysRec also integrates with the ABAP Call Monitor, Usage Procedure Logging, and Solution Documentation to perform change impact analysis for security patches.

2. Identify and analyze the security settings of SAP interfaces between systems and applications to understand risks posed by these trust relationships.

Interface and Connection Monitoring (ICMon) in Solution Manager automatically maps cross-system interfaces including RFC, HTTP, IDOC and Web Services. This includes internal and external connections. It also monitors real-time traffic patterns to detect and alert for malicious actions including dangerous RFM and URL executions.

3. Analyze systems for malicious or excessive user authorizations.

Solution Manager can detect users with administrative privileges in SAP systems. It flags users with privileged authorizations, profiles, roles, transactions, Java permissions, and HANA system and table privileges. Privileges can include standard and custom objects.

4. Monitor systems for indicators of compromise resulting from the exploitation of vulnerabilities.

The Monitoring and Alerting Infrastructure (MAI) in Solution Manager can monitor event logs in SAP systems to detect and alert for indicators of compromise (IOCs). This includes log files and tables such as the Security Audit Log, HTTP Log, System Log, Gateway Server Log, Change Document Log, Read Access Log, Java Security Log, HANA Audit Log, and the SAProuter Log. The MAI triggers alerts and email and text notifications for IOCs. Guided procedures provide a framework for incident response and tracking.

5. Monitor systems for suspicious user behavior, including both privileged and non-privileged users.

MAI monitors user logs to detect and alert for suspicious behavior covering both privileged and non-privileged users. This includes unauthorized access, escalation of privileges and actions that could lead to data leakage.

6. Apply threat intelligence on new vulnerabilities to improve the security posture against advanced targeted attacks.

SAP Partners periodically update content for Solution Manager to address new vulnerabilities and attack vectors.

7. Define comprehensive security baselines for systems and continuously monitor for compliance violations and remediate detected deviations.

Solution Manager continuously monitors for policy violations against security baselines and compliance frameworks such as GDPR, IT-SOX, NIST and PCI-DSS. Service Level Reports and Dashboards provide directions for implementing and tracking remedial actions taken to patch and secure systems. Guided procedures document incident investigation steps performed by responders. The results are archived in Solution Manager.

SAP Solution Manager is ITIL-Certified for Information Security Management

Layer Seven on January 8, 2018

The SAP Integration and Certification Center (ICC) has been validating and certifying solutions from partners and software vendors for over twenty years. The certifications provided by the ICC are based on rigorous testing and enable customers to invest with confidence in technologies that integrate with SAP solutions. This includes technologies that support security scenarios such as automated vulnerability management, code scanning and threat detection.

The ICC cannot certify SAP’s own product offerings since self-certification does not provide the same level of assurance as independent certification. However, SAP platforms are often certified by recognized certification authorities. SAP Solution Manager, for example, is certified by organizations such as SERVIEW. In fact, Solution Manager is one of the most awarded service management platforms in the market and certified for all 18 certifiable processes of the ITIL framework, including Information Security Management.

ITIL is the Information Technology Infrastructure Library and provides best practices to support the design, management and monitoring of IT infrastructure and optimization of service levels for end users. The framework consists of five distinct lifecycle phases for service strategy, design, transition, operations, and continuous improvement. It includes key performance indicators to identify problems, measure performance, and track progress.

IT Security Management is a process within the Service Design lifecycle of the most recent version of the ITIL framework. It includes four sub-processes for the design of security controls, the performance of regular security reviews, and the management of security incidents. The sub-processes are targeted at preventing, detecting and containing security intrusions and breaches. The chart below maps each sub-process to relevant applications available in SAP Solution Manager.

ITIL v3 – IT Security Management

Applications such as Configuration Validation, Service Level Reporting and the Dashboard Builder enable customers to enforce security baselines for SAP landscapes and monitor compliance against security KPIs. System Recommendations automatically detects missing security patches through a direct connection to SAP support. Interface Monitoring detects potential breaches of cross-system connections. Finally, the Monitoring and Alerting Infrastructure and Guided Procedures provide an advanced framework for detecting and responding to security incidents and suspected breaches. Overall, Solution Manager provides a powerful ITIL-compliant platform for defining, implementing and sustaining secure SAP system landscapes.
