- teach 10y agoIs this desirable? Why would one care if your live CD is able to write to the flash if it were to try?
- mjevans 10y agoYes, it is, if you want to trust that using your bootable media in a hostile system will not infect it with some firmware level nastyness. Yeah... BIOSes are attack vectors too.
- nxzero 10y agoSecurity reasons. If you boot in a hostile environment you don't have to worry about anything attacking you, hiding in free space, etc. Of course, this assumes the firmware is secured too; aka Bad USB. An OS read from a CD player that's read-only won't have this issue; that said, even if the CD is burned and all the free space too, it's likely you could introduce an exploit onto the CD by editing the encoding already on the CD by putting it in a CD player that's able to read & write to it and override the read-only flag on the CD.
