Securing SAP Remote Function Calls: The Crucial Role of S_ICF Authorization
Key Takeaways
⇨ Remote Function Call (RFC) in SAP systems can be exploited through insecurely configured RFC destinations, leading to potential lateral movement by adversaries in a compromised environment.
⇨ The S_ICF authorization object is a critical security measure that allows for fine-grained access control to RFC destinations, reducing the risk of unauthorized access and privilege escalation in SAP landscapes.
⇨ Proper assignment of authorization groups to RFC destinations requires manual effort but is essential for enhancing security, as it imposes additional runtime checks that limit access to sensitive connections.
The article discusses the importance of the S_ICF authorization object in SAP systems as a security measure to mitigate RFC hopping attacks by controlling access to RFC destinations and ensuring that only authorized users can initiate function calls, thereby reducing the risk of unauthorized privilege escalation following a cyber attack.
