@xangua: The user does not specifically ask for security updates, they are updates in general. Does it still qualify as a duplicate? – i08in Jan 3 '14 at 5:21

No,those updates are from the developers, but normally they are safe, if you just installed ubuntu, you didn't add ppa (others sources) so you just have officials ppa that are trustful. So we can consider all those updates by safe and it's recommended to do them. And for your second question, those updates can be for software, the system or the kernel.
