Thinking creatively, a South African IT company decided to use a low technology solution to complete a data transfer when their ISP network could not handle the job. Typically, quick out-of-the-box IT solutions are rarely secure. Smart technologists are good at finding solutions to meet their objectives, but when time is short, security tends to be ignored. Does the combination of frustrated people, short timelines and the need to transfer a lot of data equate to insecurity? Not always.
Being different sometimes has its security advantages. In this case data was transferred in a manner which was unpredictable to intercept, highly reliable, impossible to sniff, faster than the traditional available wired network, and maintained high security for integrity and confidentiality.
Yes, they used a carrier pigeon.
