SAP Security Testing in the Cloud Era: Challenges and Solutions

SAP Security Testing in the Cloud Era: Challenges and Solutions

In the era of cloud computing, the security of SAP systems has become a pressing concern for organizations worldwide. Many companies find themselves grappling with the daunting task of ensuring the security of their critical information. A report from Business Wire reveals that 99% of large enterprises face challenges in consistently accessing data stored in their ERP systems, with SAP being a leading ERP solution. This begs the question: how can organizations secure their SAP systems effectively amid such complexities?

The intricate nature of SAP, with its extensive customizations, makes achieving robust security a formidable task. Customization, while enhancing system adaptability, often leads to a fragmented view of SAP installations. Despite SAP’s unified structure, tailored modifications for distinct business needs can create isolated security responsibilities.

Moreover, standardizing information security practices across departments proves challenging. Unlike routine software updates akin to Windows, securing SAP demands meticulous consideration of each interface within its multifaceted architecture. This complexity necessitates a nuanced approach to discern existing configurations and ensure comprehensive hardening against malicious activities like data manipulation and unauthorized extraction.

Challenges in SAP Security Testing

Challenges in SAP Security Testing

1. Vulnerable Communication Protocols:

SAP ecosystems encompass diverse components like S/4HANA, ERP systems, SAP Gateway, Messenger Servers, RFC Gateways, and Internet Communication Manager. These components rely on communication protocols such as Remote Function Calls (RFC) and HTTP. However, many of these protocols lack encryption for stored login credentials, rendering them susceptible to security breaches.

2. Complexity of Environments:

SAP environments exhibit intricate structures due to the presence of multiple components, each requiring separate login credentials. Consequently, users often resort to password reuse, amplifying the risk. Compromising a single password could grant access to several sensitive systems. Even with Single Sign-On (SSO) implementation, password logins are permitted, exacerbating the security challenge.

3. Limited Integration with SOC:

Despite the presence of Security Operations Centers (SOCs) tasked with monitoring IT systems for breaches, SAP applications often operate in isolation from these centers. Typically managed by dedicated SAP teams, these environments lack seamless integration with SOC mechanisms. Moreover, Security Information and Event Management (SIEM) systems may not be configured to monitor SAP logs due to their proprietary formats.

4. Challenges of Custom Development:

Custom development is integral to every SAP system, involving the creation of reports, transactions, and applications by SAP programmers. However, adherence to secure coding practices is often lacking, leaving the code vulnerable to exploitation. This exposes critical applications to threats like ransomware, malware, and unauthorized access. For instance, vulnerabilities like ABAP injection and directory traversal can compromise or disrupt entire SAP systems.

5. Complexity of Hybrid Environments:

The advent of new technologies has expanded the attack surface of SAP systems, particularly in hybrid environments comprising both on-premises and cloud solutions. Managing such environments poses additional challenges, exacerbating the complexity of securing SAP ecosystems.

SAP Security Testing Solutions

SAP Security Testing Solutions

SAP provides a wide range of business applications built on various architectures such as NetWeaver AS ABAP, SAP HANA, SAP Cloud Platform, and SAP Ariba. These solutions require robust security measures, beginning with the system backend where administrators can enforce security, define roles, and set access requirements. Each SAP solution has unique security features based on its architecture, especially differing between cloud-based and on-premises solutions.

In addition to core system administration and solution-specific security features, SAP offers dedicated security products to enhance the security of your SAP environment.

SAP Cloud Identity Access Governance

SAP Cloud Identity Access Governance is a cloud-based tool that streamlines governance processes across select SAP solutions. Key capabilities include:

  • Access Compliance Management: Perform continuous analytics and leverage real-time insights to manage access compliance. Use predefined and configurable access policies and rules, and dynamically update user access as business requirements change.
  • Intelligent Assignment Optimization: Assign user access precisely and identify business-critical issues using a dashboard-based interface with visual cues and analytics-based intelligence. Dynamically modify access and manage risk using guided remediation.
  • Extended Risk Management and Control: Extend access control to all users and applications on any devices, enabling mitigation monitoring and risk remediation for separation of duties (SoD) and security for both on-premises and cloud-based systems. Simplify compliance management with pre-configured audit reports.

SAP Enterprise Threat Detection

SAP Enterprise Threat Detection (ETD) is an SIEM solution leveraging SAP HANA to manage high-volume security events such as cyberattacks in real-time. It enhances the ability to detect anomalies and mitigate attacks:

  • Log Correlation and Analysis: Analyze large volumes of log data and correlate information across the SAP environment to uncover unknown attack variants. Integrate customized third-party systems and infrastructure components.
  • Automated Threat Detection and Alerting: Use attack detection mode to find threats related to known attacks on SAP software. Define attack detection patterns without coding, investigate attacks, and issue alerts to security teams and integrated systems.
  • Integration with SAP Solutions: Detect threats at the application server and database levels and integrate with SAP solutions across the IT environment.

SAP Data Custodian

SAP Data Custodian provides security information for public cloud users while enhancing transparency and credibility:

  • Policy Creation and Enforcement: Create geolocation policies to govern data lifecycles, access, processing, storage, and movement. Modify policies in response to changing regulatory requirements.
  • Data Visibility, Alerting, and Reports: Track where and by whom data is accessed, stored, and moved in the public cloud. Notify users of policy violations and provide near-real-time risk and compliance reports.
  • Independent Encryption Key Management: Maintain independent control over encryption data and keys, separate from cloud providers, to reduce the risk of data breaches and unauthorized disclosures.

SAP Governance, Risk, and Compliance (GRC)

SAP GRC includes solutions that help manage enterprise resources to minimize risk, build trust, and reduce compliance costs. SAP Risk Management, SAP Process Control, and SAP Audit Management are examples of products that use an integrated technology platform to automate GRC processes, improve control and visibility, and monitor and enforce risk.

SAP Identity Management

SAP Identity Management handles the entire identity lifecycle, allowing administrators to control data access. It offers:

  • Connectivity: Integrate with SAP S/4HANA and third-party applications and manage identity lifecycles in hybrid deployments.
  • User Provisioning and Workflow: Simplify user access maintenance and assignment, efficiently provision business partners and employees, and establish self-service password synchronization and reset.

SAP Information Lifecycle Management

SAP Information Lifecycle Management (SAP ILM) helps manage data privacy and compliance requirements by blocking and deleting sensitive data from SAP systems:

  • Data Management and Archiving: Manage data volumes without impacting the business environment and move old data to long-term, low-cost storage.
  • Retention Management: Support the full lifecycle of unstructured and structured data, creating data management rules and policies.
