People are still dying to werposts so here's a quick guide on how to not do that
Go to a system with EDENCOM anomalies in a ship with some sort of offensive module. Corvettes work. Warp in to an EDENCOM anom, align out, shoot one ship, warp off. Wait. In 15-20 minutes your standings will ding -0.003 EDENCOM. You will also get an equivalent positive standings increase with the Trigs.
Trig rats will not shoot you if you have standings above 0.000, EDENCOM rats will not shoot you if you have standings above -1.000. Both sides should appear as neutral NPCs and will not agress you. Travel empire space freely and without feeding pods to werposts :)
From TVN, Obe is the closest system with an EDENCOM anomaly. I would suggest jump cloning or having someone covops bridge you in, as every gate is hellcamped by trigs. From empire space, open up the Agency Menu and go to the Triglavian Invasions tab. EDENCOM fortress systems won't have werposts and will have plenty of anoms.
