Modern Computing is Fundamentally Broken
I've often thought the modern computing / Internet is fundamentally broken.
It is my opinion, when it comes to "this online crap" NOTHING is secure and despite all of the "experts" who believe otherwise... it's simply impossible for something to ever truly be secure as long as it is "online" and accessible remotely.
It's simple: if I can access my online accounts remotely using a computer or a phone then OTHERS can access those same online accounts.
Updates... the fact that everything is continually being updated introduces bugs creating new security holes even as the old ones are patched.
Employees... even if I do everything to keep an account secure, it can be undone by an employee "going rogue", or clicking on a link in an email and getting a virus on their machine, or them falling victim to social engineering.
Virtual... lack of physical risk. If people had to physically break into buildings and rummage through filing cabinets or even local offline computers there would be so much less crap going on.
Beyond the "connected to the world" flaw... another major issue with modern devices is persistence.
Devices have OSes with all software installed directly within the same drive. Everything persists. Turn on the computer or phone and the OS loads and brings with it all of the viruses and other exploits that previously infiltrated the system.
Back in the C64 days we turned off the computer for 30 seconds, turned it back on and everything was purged. Software and data and even any OS were stored on external media and only loaded as needed.
It was still possible to get a virus on external media even back then but it was much more limited in scope.
What makes viruses so damaging now are (1) extreme persistence and (2) world connectivity as standard.
Although I completely wipe my internal hard drive and do a fresh OS install every ~4 months sometimes changing distro... I've considered wiping the internal hard drive and booting the OS from USB. This would be much closer to that old computer way.
