Do you trust your SAP systems?
In recent years, we have seen many changes in the IT business: from on-premise to cloud-based computing, from smart computing to the increasing use of Artificial Intelligence (AI), from Big Data to Data Transformation, from batch-oriented to real-time, from working on-site to working remote and so on, leading to ever-increasing complexity in IT architectures.
At the same time, cyber-related crime has evolved in a similar manner, making the jump from individual malicious actors to organized crime syndicates, often established, and supported by governmental structures.
It may therefore come as no surprise that new security paradigms have evolved too. One of the latest ones is called “Zero Trust”. The National Cyber Security Centre (NCSC) in the UK identifies the following key principles of Zero Trust:
- Single strong source of user identity
- User authentication
- Machine authentication
- Additional context, such as policy compliance and device health
- Authorization policies to access an application
- Access control policies within an application
Basically, Zero Trust is a theoretical approach for architecting and building new IT infrastructures using sound security principles and complete control of users and access to resources.
But Zero Trust also has a basic flaw: it does not consider the risks of the resources themselves.
Let’s presume that an organization does not have any patch and vulnerability management process in place for their SAP systems. Spending a lot of money on user and machine authentication and safe access while at the same time allowing these users access to unsafe SAP systems makes no sense at all.
Zero Trust ignores the risks within the resources themselves while focusing on access controls.
An SAP system that is not patched, hardened, and is not subject to a strict security policy, is an environment in which SAP user accounts can be hijacked or compromised in many ways.
Before enabling a security model like Zero Trust in an SAP infrastructure, you must close this gap first by implementing a patch and vulnerability management process.
Over the last 25 years, SAP has made great efforts to enhance its security posture and nowadays many of the standard SAP security-related parameters now have safer default settings. Also, many new security-related parameters and features are now part of the standard delivery.
However, one fundamental principle has remained the same for the last 25 years:
SAP Customers must adapt the security settings to their own specific infrastructure.
Without this adaptation, a newly deployed out-of-the-box SAP system located somewhere in a cloud can be detected and hacked by 3rd parties in a short matter of time.
SAP customers must prevent exploitation of vulnerabilities in their SAP systems by making the required changes to these systems to minimize their risk surface and implement their own IT infrastructure policies.
To harden their SAP systems, SAP customers must start with the basics and define, implement, and monitor a security baseline and maintain many detailed security configuration settings.
In addition, SAP customers must stay up to date with the monthly release of SAP security Notes.
Protect4S provides a simple 3-step security process enabling continuous improvement of SAP security and supports the key principles of zero trust by helping to secure and harden SAP systems.
