Secure Online Banking with Ubuntu

Instructions for ubuntu users

There is a simple way to create USB start up disk in Ubuntu. You will need 1G USB disk and just use standard tool "System > Administration > Create a USB startup disk"

Select "Discarded on shutdown" for better security or use "Store in reserved extra space" to save changes you have made to the system, but iptables settings will be reset on restart. Remaining disk space you can use as before.

Save IPTables firewall setup script to your hard disk (let's say path to scipts will be /home/user/scripts/firewall/) with some small changes. You can also read Basic iptables howto.

Skip this if you have DHCP - Dynamic Host Configuration Protocol.

If you have Static IP then create two files in scipts folder (see above).

- "resolv.conf" where you add name servers. For example:

nameserver 10.0.1.2
nameserver 10.0.0.2

- "interfaces". For example:

auto lo
    iface lo inet loopback

auto eth0
    iface eth0 inet static
    address 192.168.xxx.xxx
    network 192.168.xxx.xxx
    netmask 255.255.255.0
    broadcast 192.168.xxx.xxx
    gateway 192.168.xxx.xxx

Change xxx to you actual settings.

And add these lines to the end of the firewall setup sript

# Configuring Static IP

cp /media/disk/home/user/scripts/firewall/resolv.conf /etc/resolv.conf

cp /media/disk/home/user/scripts/firewall/interfaces /etc/network/interfaces

/etc/init.d/networking restart

Start up your computer from created disk.

Run "firewall.sh" script in "Terminal" ("Applications > Accessorisies > Terminal"):

cd /media/disk/home/user/scripts/firewall/

sudo sh firewall.sh

That is all. Now you can do Secure Online Banking.
