An interesting article covers Aruba's opinions on secure fortress mentality:

"Aruba's recommendation is to do that by providing providing people who work from home with an office-grade wireless access point. It plugs into their existing modem/router and creates a separate Wi-Fi network for work use."

Well, while this will work, it is a hack that doesn't really fixes core issues of poor network security and creates additional pain for workers, especially the ones on the go, it creates inconvenience around context switching (e.g. Modern blend of personal and work tasks). I think there is no way around securing internal IT infrastructure properly based on Zero Trust Network. #zerotrustsecurity
