Deep dives
Understanding PFSync Protocol
PFSync is a network protocol used to synchronize state information between primary and secondary firewalls, ensuring effective failover during session establishment. Originating from the OpenBSD project, it operates under an unusual protocol number and lacks a standard IETF RFC, resulting in limited tools for packet analysis, like Wireshark. This limitation raises challenges in monitoring PFSync traffic, as some versions may not adequately recognize or analyze it. Despite these obstacles, PFSync is significant for both offensive and defensive security insights, emphasizing the need for proper configuration to prevent data leakage and mitigate network performance impacts.
