Live CD Security?


Recommended Posts

I was wondering how secure the Live CDs are? My hard drive died recently, so instead of waiting 5 days for a new hard drive, im running the live CD since I need to get some work done. Is the live CD secure?

And is it normal to slow down or drop audio sometimes? Like if I hit refresh on Firefox, the audio will stop running while the CD spins up and gets read. I guess its normal since it is reading from the CD

It does slow down at times (at least for me) while CD/DVD spins up for while trying to do certain things but I haven't had issues with dropped audio.

Secure, Very reasonably so. And, if (against the odds) you pick up some obscure Linux malware or you play around and enable passwordless root login via ssh and get rooted...

Reboot and you are clean off the CD again.

As for the performace issues, a chunk of RAM is used to decompress the data on the CD into memory, and there is a bit of latency (is that the right term, I'm not sure) when the session needs to read something from the CD.

If you got a lot of ram, live cd like slax and some other (mepis got this option too i think) have the option "toram" at boot that allow you, if you have many gb of ram to preload the whole cd on ram, this will be extremely fast compared to tradititional live-cd and even HDD install (1200mbs instead of 55)

Do I just select more options? I have 6GB of ram but am using 32-bit so only 3.5 is seen (unless linux/ubuntu is different) ill see what I can do next time I boot

Linux may see few more megabyte, but it will not go over 3.6, it is an hardware limitation ram+video ram+bios cache have to stay under 4 billions of bit. But *Ubuntu do not provide the toram option. And you can use a 64bit version of linux, the only problem you will have is that you will have to install the 32bit version of firefox to get a decent flash plugin (the adobe one) and 32bit version of a media player to play some kind of video (most of them will work in 64bit, but many proprietary codecs are available only in 32bit).

64bit Ubuntu comes with a 64bit version of mplayer that still plays anything under the sun. The only thing you'd have to do if you can't live without Flash is doing the ia32-libs thing.
