What is jnxJsScreenSynAttackAlmTh?

This read-only value reports the SYN-attack alarm threshold: the rate of proxied half-complete connection requests to the same destination address and port, per second, above which the device raises an alarm. An admin reads this to know at what point a rising SYN rate escalates from silently proxied to actively alarmed.
