I'm a beginner of the Unbuntu OS. I'd like to create a live cd to surf in websites like paypal, ebay and keep out malware (in particurally new generation zero day malware that use keylogging and ssl sniffing, often not detected by most av vendors).
For this reason I need help in the creation of live CD: how can I improve security at the highest levels (firewall, read, write, and execute permission)?
Are there security tool Can I add to live CD?
