But geez, come on, we have enough security on our computers now that is makes doing our job almost impossible. Software doesn't run correctly, websites and network backbone aren't Windows 10 compatible, and now they want to INCREASE the amount of security? We won't be able to do squat if the gubermint enacts even more security measures.
One would hope that good security architecture would eliminate some of the conflicts you are now experiencing and make a more globally compatible system with revised and streamlined layers of protection. As noted above, such an implementation would probably take more than 3 to 6 months; but getting the agency heads on top of assessing the needs is a necessary first step that the EO calls for.
