IEC 60870-5-104 (IEC 104) is a many-to-one remote monitoring communication industrial protocol. Utilized by a variety of Critical Infrastructure verticals, IEC 104 is commonly used for telecontrol equipment and systems that require data transmission for monitoring geographically widespread practices remotely.
Unlike industrial firewalls, the IEC 104 protocol combined with an Owl data diode, provides hardened security that cannot be hacked. With less maintenance compared to industrial firewalls, this combined solution is the most effective method for power transmission and distribution organizations to securely collect monitoring data from their substations.
