I currently keep a hosts file to make my online banking more secure. But that won’t help in the event of a DNS-cache-poisoning zero-day attack. Is the following solution practical?
Dedicate one browser for secure online banking, and dedicate a different browser for normal browsing of the Internet. The secure browser would be restricted to a whitelist containing only by bank’s IP addresses. Is there a way to restrict IP addresses for just one browser? (hosts file won’t work because it restricts all browsers) The browsers would run on Ubuntu 11.04.
AhnLab Inc sells a dedicated browser specialized for secure online banking:
AhnLab - Antivirus Software and Security Solutions Provider
Is there a similar browser in open-source land?
Another option is to boot Linux USB live, with it’s own hosts file:
Secure Online Banking with Linux USB Live https://www.ironkey.com/personal
I want to investigate the dedicated browser option before I commit to using Linux USB live.
Thank you for your input.
