Security is the degree of resistance to, or protection from, harm. It applies to any vulnerable and valuable asset, such as a person, dwelling, community, nation, or organization. Security provides a form of protection where a separation is created between the assets and the threat. These separations are generically called controls, and sometimes include changes to the asset or the threat.
Choosing an OS
Your operating system the most important layer in your security model. You should try to test and evaluate all OS's to find that perfect match between security and usability.
- Tails - Tails serves as a pre-configured out-of-box secure OS which can be easily loaded onto removable media. Its ease of use while still forcing a secure protocol makes this OS a great contender. (clearnet link)
- Whonix - As with tails, Whonix forces all communication through the Tor network. However, Whonix uses a VM to ensure isolation of the user from the network. As such, it is a little more complex to setup and maintain. Nonetheless, Whonix serves as a viable alternative to the Tails OS for any user who wishes to keep a persistent OS on disk. (clearnet link)
- Kali - While not geared towards being out of the box secure, Kali is a powerful tool to exploit network vulnerabilities.
