Which of the following is the stance on risk that by default allows traffic with a default permit approach?

BPrudent

CPromiscuous

DPermissive

Show Suggested Answer

Suggested Answer: D

Modbus TCP is a variant of the Modbus family of simple, networked protocols aimed at industrial automation applications. Unlike the original Modbus protocol, which runs over serial links, Modbus TCP runs over TCP/IP networks.

Port 502 is the standard TCP port used for Modbus TCP communications. This port is designated for Modbus messages encapsulated in a TCP/IP wrapper, facilitating communication between Modbus devices and management systems over an IP network.

Knowing the correct port number is crucial for network configuration, security settings, and troubleshooting communications within a Modbus-enabled ICS/SCADA environment.

Reference

Modbus Organization, 'MODBUS Application Protocol Specification V1.1b3'.

'Modbus TCP/IP -- A Comprehensive Network protocol,' by Schneider Electric.

I'm feeling a little 'Permissive' today, if you know what I mean. Time to let it all hang out!

But doesn't a default permit approach suggest a more permissive stance on risk?

I think the default permit approach sounds like a bit of a gamble. Might as well roll the dice with 'Promiscuous'!
