Security

The DNP3 protocol implemented in the EDS001 module is not explicitly secure; nor is the
access to Controller memory explicitly secure. Steps must be taken to secure the network
from unauthorized control, interception, or access to the DNP3 communications. Steps
must also be taken to secure the Controller from unauthorized access or control using the
security features found in the latest released versions of PAC Machine Edition 7.0 and
PACSystems RX3i CPU firmware.
Emerson strongly recommends that the DNP3 CROB control memory NOT be permitted to
be directly connected to control devices. Such devices should also be protected from direct
access using the security features found in the latest released versions of PAC Machine
Edition and PACSystems RX3i CPU firmware. Consult Emerson technical support for more
information.
Emerson also strongly recommends that the EDS001 modules, in all instances, be updated
with the latest released version of EDS001 firmware to ensure all available security
enhancements
