Abstract
Under the efforts to transition to an open radio access network (RAN), movements like O-RAN have emerged. One of these movements' goals is opening RAN interfaces (like the open fronthaul (O-FH)), to break the vendor lock-in of RAN resources. However, this raises concerns about RAN's security especially in elements that are bound to latency and performance requirements like the O-FH's synchronization plane (S-plane). In this article, we provide a comprehensive discussion of S-plane threats following O-RAN architecture, considering used synchronization protocols and mandatory security requirements. Further, we discuss the identified threats' impact on S-plane synchronization topologies and comment on possible countermeasures. Finally, we leverage O-RAN properties and benefits to propose future research directions for better S-plane security.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
