Exam XSIAM-Engineer Topic 2 Question 102 Discussion

Actual exam question for Palo Alto Networks's XSIAM-Engineer exam
Question #: 102
Topic #: 2
An XSIAM deployment requires ingesting logs from a highly isolated industrial control system (ICS) network. Direct network access from the corporate network to the ICS environment is strictly prohibited due to security policies. The ICS systems generate a mix of Syslog (UDP) and OPC UA data'. How can XSIAM effectively collect and analyze these logs while maintaining the strict network isolation?

Suggested Answer: A Vote an answer

For highly isolated ICS networks with strict one-way communication requirements, a data diode (often combined with a dedicated proxy/broker) is the most secure and compliant method. It physically enforces unidirectional data flow, preventing any inbound connections to the ICS network while allowing logs to be securely transferred out. Other options either violate security policies (C, E), are highly inefficient/manual (B), or rely on unverified vendor capabilities (D).
