    security with ubuntu live dvd

    according to info on the directions on the ubuntu live dvd session, it says that the computer may be compromised by doing this? why would one want to take this chance?

    Security and Updating

    While linux systems are more secure than Windows, LiveCD sessions are not meant for long-term use nor for sessions lasting several days. Because LiveCDs can't easily be updated, they may well be vulnerable to security issues discovered in the months since their release. They also can't protect you against scams such as phishing. If a criminal broke in to your live session, any changes he made to your session would be reset along with everything else when you reboot, although he could make permanent changes to the computer's hard drive.

    A persistent image can be updated as new security issues emerge, but also lets any damage done to your computer persist across sessions.

    Re: security with ubuntu live dcd

    A reason live session are less secure than an install is because live sessions don't need a password to gain root.

    Moved to Security Discussions sub-forum. Should get better answers about security there.
    Use whatever OS or desktop works for you. Backup your computer regularly, and definitely before updating, upgrading, or partitioning.

    The advice you quoted is not entirely true. Wait for relies from the security forum before making an assumption like that.

    Are you asking the question from your OP ?

    Why use it ?

    Because it is to see if you like it and it works mostly with your hardware and needs.

    As it states in the quote you posted:

    Boot a liveCD and you can access any drives in the machine.

    Unless you have a specific reason for using a livecd (testing/troubleshooting), don't bother.

    Re: security with ubuntu live dcd

    so your advice is not to run a live dvd to run ubuntu, to be on the internet etc? only use it to trouble shoot?
