Check Point cluster stability improvement to prevent incorrect change of cluster members state to "Ready" Technical Level

This attack is possible if a malicious user gains Layer 2 access to cluster non-trusted (non-sync) interfaces (whose "Network Objective" in cluster object topology is not "Sync").
