Security :: Some Precaution Should Take To Protect Notebook From Intruders?

Jun 3, 2010

I am planning a trip for a few days and I will be staying at an inn with Wifi access. All the guests are allowed to use it. A friend of mine has been there, he told me there are several other private spots around the house, i.e. lots of other people using Wifi. My friend told me the inn uses WEP, so who knows how many times their access point has been hacked and accessed without permission...

My concern is that I will be there for a few days with my notebook, I will have to work once in a while, connected to the Internet. Is there some precaution I should take to protect my notebook from intruders? Is it advisable to install a firewall in my notebook (iptables?) or am I just overreacting? Is it possible for one of the guests or neighbors to break into my notebook?

General :: Install Logwatch As A Security Precaution?

Sep 11, 2010

I was advised by a fellow forum owner to install logwatch as a security precaution. Our forum runs on a dedicated server. CentOS 5.5. I ran "yum install logwatch" and got the following:

Code:

Marking logwatch-7.3.6-1.noarch.rpm to be installed
Resolving Dependencies

Ubuntu Security :: How To Protect From Untrusted Files

Oct 8, 2010

I want to start using videos/music files downloaded from untrusted sources (BT,Sharing Forums, etc.). Haven't made this a habit b4 because of the security risks. I want to take steps to reduce the risk & protect my computer from anything malicious. What are some good choices for this? The biggest step I took so far is using Ubuntu since it's very virus resistant, but other threats do exist out there (rootkits, malicious scripts, etc.). When downloading files from untrusted sources, who knows what may be hidden inside.Some options I'm thinking about:

1) Using a VM (with Ubuntu installed inside) & playing the files inside the VM. If anything malicious happen, it would be trapped inside & I could easily revert to a clean snapshot.

2) Using AppArmor to restrict what the files or program used to play the files can/can't do. AA seems very complicated though.

Are the above overkill? Would it be sufficient enough to just open these files on a non-admin user account since no access to root or sudo?

General :: Intruders Can Log Into Box Using Run Level 1 Without Using Password

Mar 23, 2010

Well I have been using linux for sometime, and have kept strong passwords for every user account. But recently I noticed when we boot into run level 1, it does not ask for any password.This means that anyone can turn on my computer in my absence, on grub menu press a, then 1 to append 1 to the kernel arguments, which will make my system boot in run level 1.It won't ask for any password. Once in run level 1, the intruder can easily access my files, copy them, change their permissions, change even the root password.

Now how can I make my system more secure? Is there a way to get detailed info of each log in session, like which user, which run level, for how long and things like that?
