A manufacturer placed a series of connected sensors along an assembly line to track and relay operational details. Analysts discovered frequent attempts by unauthorized parties to read intercepted network traffic. Which measure is most likely to reduce risk without disrupting standard activities for these devices?
Use encryption that protects data as it travels between the units and the server
Block inbound traffic from outside networks while sending unencrypted messages
Deactivate local event recording to limit stored information
Ensuring transmissions are protected by strong encryption, such as Transport Layer Security (TLS), prevents unauthorized parties from reading intercepted data. Restrictions on inbound sessions or shutting down local logging do not address confidentiality for data in flight. Disruptive tactics like frequent restarts can impact normal operations without adequately protecting information.
