In today’s rapidly changing digital world, SAP systems form a key component of many enterprises’ IT infrastructure. As a Gold Partner of both SAP and SUSE, SNOK understands the unique challenges involved in securing these systems. As part of our “Safe Tuesday with SNOK” initiative, we also address best practices and strategies that help protect SAP systems on the SUSE Linux Enterprise Server for SAP platform, ensuring operational reliability and security.
Why SAP on SUSE?
Choosing SUSE Linux Enterprise Server for SAP applications is not a decision taken lightly. It is the direct result of a long-standing and close collaboration between SAP and SUSE, which began more than two decades ago. The aim of this collaboration is to optimise and secure SAP environments, which is critical given the growing demands placed on business data and applications.
The history of the SAP-SUSE partnership dates back to the 1990s, when the first versions of SUSE Linux Enterprise Server tailored specifically for SAP applications began to appear. Since then, SUSE has become one of the key players in the SAP ecosystem, offering solutions designed to support the reliability, performance and security of critical business systems.
Today, in the context of SAP’s introduction of the SAP HANA database, which requires operating systems with high performance and stability, the collaboration between SUSE and SAP has taken on a new dimension. SUSE Linux Enterprise Server is one of only two operating systems officially supported by SAP for SAP HANA, underlining its importance and the trust SAP places in it.
What makes this collaboration particularly significant today is the growing demand for real-time data processing and the need to ensure business continuity and data security. In a world where digital transformation and real-time analysis of large datasets are becoming the standard, choosing the right operating system for SAP HANA applications is critical to enterprise success.
Thanks to this collaboration, users benefit from an operating system designed to maximise the performance and security of SAP applications, delivering optimal results and peace of mind when managing critical IT resources.
1. Security built in from the ground up
The SUSE platform was designed and built to provide the highest level of security for enterprise systems, including critical SAP applications. From the outset, security has been a core element of the architecture of SUSE Linux Enterprise Server, giving users access to advanced protection features. One such feature is automatic patching without downtime, known as live patching. This innovative technology allows system administrators to apply critical security updates in real time, without needing to restart the system or applications - which is extremely important in environments where every second of downtime can generate significant financial or operational losses.
However, the advanced security mechanisms offered by SUSE do not end with live patching. The platform also provides integrated identity and access management tools, encryption of data at rest and in transit, advanced network security, and tools for security analysis and monitoring. This enables organisations to build robust, multi-layered security strategies that protect their data and applications against a wide range of threats, from external attacks to insider threats and configuration errors.
Moreover, SUSE actively collaborates with the open-source community and industry partners to continuously identify and respond to new threats. As a result, SUSE Linux Enterprise Server users can rely on an operating system that not only offers advanced security features, but is also regularly updated to counter the latest threats. Combined with deep integration into the SAP ecosystem, where data security and business continuity are absolutely critical, SUSE Linux Enterprise Server forms the foundation of a secure and reliable IT infrastructure, enabling organisations to focus on business growth rather than risk management.
2. Access management and control
Access management and control within an SAP environment on the SUSE platform form the foundation of an effective security strategy. At SNOK, we understand that proper identity and access management not only protects critical resources from unauthorised access, but also ensures compliance with increasingly stringent regulatory requirements for data protection and privacy. Thanks to the advanced identity and access management tools available on the SUSE platform, we are able to offer our clients comprehensive solutions that enable precise definition and enforcement of access policies.
Implementing the principle of least privilege - granting employees access only to the resources and functions strictly necessary for their tasks - is a key element of our strategy. This approach not only increases security by reducing the potential attack surface, but also simplifies resource management and minimises the risk of human error that could lead to security breaches. At SNOK, we support our clients in analysing and defining their employees’ access needs, enabling the creation of a balanced working environment where security goes hand in hand with operational efficiency.
Regular audits and access reviews are an essential element of maintaining a high level of security. They allow not only the detection and elimination of excessive privileges, but also the monitoring and analysis of user behaviour, enabling early identification of potential internal and external threats. At SNOK, we apply comprehensive audit procedures that combine automated access-monitoring tools with regular manual reviews. This allows us to quickly adapt security policies to a changing environment and ensure that our clients’ systems are always protected against the latest threats.
In summary, access management and control within an SAP environment on the SUSE platform is a comprehensive process that requires continuous monitoring, analysis and adaptation to changing conditions. At SNOK, thanks to our experience and the advanced tools available on the SUSE platform, we are able to provide our clients with the highest level of security for their SAP systems, while minimising risk and maximising operational efficiency.
3. Regular training and awareness-building
When it comes to securing SAP systems on the SUSE platform, technology alone is not enough - user awareness plays an equally critical role. In a world where cyber threats evolve daily, understanding and being able to identify potential attacks, such as phishing or malware, is essential for anyone working with SAP systems on a daily basis.
Raising cybersecurity awareness among users of SAP systems on SUSE is important because people are often the first line of defence against cyberattacks. Education in safe online practices and the recognition of suspicious behaviour can significantly reduce the risk of security breaches. It is therefore important for organisations to implement awareness programmes that help employees understand how their actions can affect company security.
In the context of SAP on SUSE, particular attention should be paid to access and privilege management, which is critical to protecting sensitive data and business processes. Regular reviews of access policies, implementation of least-privilege principles, and monitoring of user activity are all measures that can help prevent unauthorised access.
In summary, in an SAP environment on the SUSE platform, building a culture of security and raising cybersecurity awareness among users is just as important as advanced technological solutions. This combination of technology and education creates a solid foundation for the secure and effective use of SAP systems in any organisation.
4. Monitoring and response
The advanced monitoring tools available on the SUSE platform are a key element of an SAP security strategy, enabling not only continuous tracking of system activity but also rapid detection of, and response to, any anomalies. At SNOK, thanks to our deep understanding of working with SAP systems on the SUSE platform, we use these tools to create a layer of proactive protection for our clients’ SAP environments. This enables us not only to monitor, but also to analyse system behaviour in real time, allowing early identification of potential threats and rapid remedial action.
These tools offer a wide range of functionality, from simple system log monitoring to advanced user behaviour analysis and intelligent algorithms that detect unusual patterns of activity which may indicate attempted security breaches. Integrating these tools with SAP systems on the SUSE platform provides comprehensive protection tailored to each client’s specific requirements and configuration.
At SNOK, we have developed working methodologies that allow us to make the most of the capabilities offered by the SUSE platform, which, combined with our experience in managing and optimising SAP systems, translates into exceptional added value for our clients. Our approach is based on continuous improvement of monitoring and analysis processes, allowing us to ensure not only a high level of security, but also the optimisation of SAP system performance.
5. A comprehensive patching strategy
In today’s fast-moving cybersecurity landscape, regular updates and patching are no longer just a recommendation - they are an absolute necessity for any organisation seeking to protect its resources against increasingly sophisticated threats. At SNOK, we fully understand this need, which is why we actively support our clients in developing and implementing comprehensive patching strategies for SAP systems running on the SUSE platform. Our efforts are not limited to reactively patching known vulnerabilities; we also aim to anticipate potential threats and prevent them through continuous monitoring and analysis of cybersecurity trends.
Ensuring that all system components are not only up to date, but also optimally secured against the latest threats requires in-depth knowledge of both SAP systems and the SUSE platform. Thanks to our experience and specialist expertise, we can offer our clients not only technical support, but also strategic advice that maximises security while minimising disruption to operations.
At SNOK, we place great importance on the patching process, treating it as an integral part of managing SAP system security. Our approach includes regular security reviews, risk assessment for individual vulnerabilities, and prioritisation of patching activities based on the client’s specific business context and potential threats. Through close collaboration with our clients’ IT teams, we are able to deploy necessary updates quickly, while ensuring the process is as unobtrusive as possible for day-to-day operations.
