Top 10 Things to Consider 
for Effective SAP Security

It was a typical Tuesday for most, but in the world of SAP security, September 12, 2023, sounded alarms across the globe. SAP's Security Patch Day dropped a bombshell.

Thirteen new vulnerabilities, five branded as HotNews – a hacker's dream and a CISO's nightmare.

Two vulnerabilities in particular – CVE-2023-0014 and CVE-2021-27610 – scored a jaw-dropping 9.8 on the CVSS scale, a near-perfect storm of digital devastation. For organizations relying on SAP systems this meant - one remote hacker, one exploit, and suddenly company's sensitive info – from customer data to financial records – could all be up for grabs, opening doors to potential corporate espionage, operational sabotage, and sophisticated fraud schemes.

In light of these persistent threats, securing SAP environments has never been more crucial. Organizations must adopt a proactive stance, implementing robust security measures to safeguard their SAP landscapes against cyber risks. Effective protection strategies will not only shield sensitive data but also ensure business continuity and maintain stakeholder trust.

To assist organizations in this endeavor, we've identified 10 key considerations that form the cornerstone of a strong SAP security posture. Let us go through them in detail. 

From Mainframes to AI: SAP’s Transformative Path to Security

The evolution of SAP security has been closely tied to the broader transformation of IT enterprises and the changing threat environment:

• Early Days: In the beginning, SAP security services primarily focused on basic access controls and user authentication for mainframe systems.
• Client-Server Era: As SAP moved to client-server architecture, security concerns expanded to include network security and more granular access controls.
• Web Applications: The introduction of web-based SAP applications brought new challenges. Firewalls became the new gatekeepers, and VPNs the secure tunnels through which SAP data flowed. But with connectivity came vulnerability – each new interface a potential entry point for cyber attackers.
• Compliance Focus: Increasing regulatory requirements led to a greater emphasis on compliance-driven security measures within SAP systems.
• Cloud and Mobile: The adoption of cloud solutions and mobile access to SAP systems introduced new security instances and solutions. How to secure data when it's no longer within four walls? SAP responded with robust encryption, identity management, and secure APIs. The concept of "shared responsibility" emerged, with both SAP and its customers playing crucial roles in maintaining security.
• Present Day: Today, SAP Security services encompass a comprehensive framework designed to protect against both internal and external threats. It includes Infrastructure, Network, Operating System, Database, Coding security and practices. Machine learning algorithms scan for anomalies, predicting and preventing attacks before they happen. Automated patch management ensures systems stay up-to-date against the latest threats. And with the advent of S/4HANA, security is baked into the very core of SAP's architecture.

But perhaps the most significant shift has been in mindset. SAP security is no longer just IT's problem – it's a board-level concern.

With these foundational concepts in mind, let us now explore the critical factors that every organization should consider when developing and implementing their SAP security strategy.  

SAP Security: Top 10 Things to Consider

1. User Access Management and Authentication

One of the foundational pillars of SAP security services is effective user access management. This involves not only controlling who has access to the SAP systems but also implementing strong authentication mechanisms to verify user identities.

Consider implementing:

• Multi-factor authentication (MFA) for all user accounts
• Role-based access control (RBAC) to limit user privileges
• Regular user access reviews and audits
• Single Sign-On (SSO) solutions for seamless and secure authentication across multiple SAP applications

When selecting an SAP security service provider, ensure they offer comprehensive user access management solutions tailored to your organization's specific needs.

2. Patch Management and Vulnerability Assessment

Keeping SAP systems up-to-date with the latest security patches is crucial in maintaining a strong security posture. Regular vulnerability assessments help identify potential weaknesses before they can be exploited by malicious actors.

Key considerations:

• Establish a robust patch management process
• Conduct regular vulnerability scans of your SAP landscape
• Prioritize and address critical vulnerabilities promptly
• Leverage automated tools for efficient patch deployment 

In 2020, SAP released a critical patch for a vulnerability (CVE-2020-6287) that could allow attackers to take control of affected systems. Many organizations had quickly applied this patch to reduce their risk exposure.

Note: Look for SAP security solutions that offer automated vulnerability scanning and patch management capabilities to streamline this process.

3. Network Security and Segmentation

Protecting the network infrastructure that supports SAP systems is essential in preventing unauthorized access and data breaches.

Consider implementing:

• Network segmentation to isolate SAP systems from other parts of your network
• Next-generation firewalls with application-aware filtering
• Intrusion Detection and Prevention Systems (IDS/IPS) specifically tuned for SAP traffic
• Secure communication protocols (e.g., TLS) for all SAP-related network traffic

4. Data Encryption and Protection

Protecting sensitive data at rest and in transit is a critical aspect of SAP security. Encryption helps ensure that even if data is intercepted or accessed without authorization, it remains unreadable and unusable to unauthorized parties.

Key areas to focus on:

• Implement strong encryption for data at rest in SAP databases
• Use secure protocols (e.g., HTTPS, SNC) for data in transit
• Implement SSL/TLS for all communications to and from SAP systems, including RFC connections
• Employ data masking techniques for sensitive information in non-production environments
• Implement key management solutions to securely store and manage encryption keys

Note: When evaluating SAP security solutions, look for options that provide comprehensive data encryption capabilities across the entire SAP landscape.
