can someone describe to me how Linux's security and privacy stacks up against Windows 11? i'd like to know the strengths and weaknesses, especially factoring in secure boot, bitlocker and Windows Defender. what flaws should be aware of in Linux and how do i fix them? what should i enable or disable in linux to improve privacy/security?
you're in a bazzite channel, so I'll assume you're asking about bazzite. Bazzite can (and will if you don't tell it not to) install to a disk encrypted with the same general strength as bitlocker. By default it'll be using a stretched password as the encryption key. After booting it up you can run a ujustujust command which will switch to using Measured Boot with the system TPM chip (leaving the stretched password as a recovery key of sorts)
now when it comes to privacy... Linux is far, far, FAR superior to Windows 11. Windows is out of the box filled with telemetry reporting to Microsoft, and in fact it's not possible to set up a Windows 11 install without connecting your local user account to an online MS account (without launching a terminal during the install process and running special bypass commands Microsoft has said they'll remove)
"Windows Defender" is not great for privacy thanks to its "SmartScreen" feature that sends Microsoft details about which binaries you're running on your system. Antivirus-wise Bazzite comes with nothing out of the box, but... Linux also doesn't have many viruses targeted at it, and the general threat surface is lower
reminder: bazzite is designed for playing video games. Playing video games isn't really supposed to be done inside fort knox. But the posture overall is more than acceptable to me.
The very nature of of Linux is difficult for virus's to take hold. You'd have to to explicitly give them root access for any real damage to take place, not to say there isn't any stupid things people have done, or some malware people can install in in the userspace. It's generally very uncommon in Linux, but has happened every now and then.
now in theory, if i do something dumb and install a virus by mistake (which i've done in the past lol i was a dumb kid), what do i do? what terminal commands or program do i run?
reset, since the core os is read-only, and immutable, it deletes layers of configs and updates that have been added to it, and resets it to just the base OS. Your /home you would remaine intact, unless you choose to nuke that as well
would that mean deleting all my data? let's say i mount my drives after a dual-boot and i accidentally install a virus on either OS, could it infect the other OS?
