Can be global▪ e.g. all MS Windows everywhere

Can be local ▪ e.g. a business using Linux for all desktops

Can be software or hardware MS Office Cisco network equipment Intel processors Gaming systems: PS4s or Xbox One

Monoculture vs. Standards vs. Protocols

Standards and Protocols are not monocultures Example:

TCP is a protocol:▪ Proscribes how to send packets▪ Different systems use different software to implement the

protocol▪ An error in one implementation would not be seen in a different system

SSH is a standard▪ OpenSSH is one implementation of that standard▪ There are others

Intel could be a monoculture▪ Error in the design of a processor would be seen in all systems

using that processor

Monoculture

Pluses Uniformity ease of use▪ Lower training costs

Transferability▪ Easy of interoperability between programs and data

Economy of scale Negatives

Vulnerability to common attacks Monopolies▪ Higher cost▪ Less innovation

Less freedom for choice of proper solution

Monoculture

Monoculture is not an MS problem only Can be any exclusive system Best?

No best solution Choose for the conditions▪ Business is "uniform"▪ Monoculture may be the best solution▪ Ensure to address potential problems $$$

▪ Business has various needs▪ Use the best solution for each need▪ Spend the $$$ to support the more complex environment▪ Still need to worry about security
