One thing I do with my internet-connected devices is disconnect the network signal when I’m not using them. Other times I power down the device completely. On Ethernet connected computers I will shut down the ethernet switch in my office when I leave for extended periods of time(like sleeping). A switch is a network device that connects many ethernet computers together in one location to another location in a building.
On most laptops there are ways to disconnect the WiFi by using the icon on the taskbar. This can be done in Windows, Apple, and Linux.
My hope is if my security breaks down, they will be less vulnerable since they are not on the internet. For computers always connected, this gives hacker software or a person more chance to penetrate your devices.
