** Install Bitmessage
|
||||
|
||||
[[https://bitmessage.org][Bitmessage]] is a new type of messaging system intended to fulfill the same role as email, but without the security problems. In particular, Bitmessage attempts to not just encrypt the content but also the metadata. It's message broadcasting system makes it exceedingly difficult for an attacker to know which computer a message is destined for. The only way you know whether a message has been sent to you is whether you are able to decrypt it from the passing stream of messages.
|
||||
|
||||
Although similar to Bitcoin in some regards, such as "/proof of work/", Bitmessage has no block chain and messages are only buffered for approximately three days after which they are deleted from any given node.
|
||||
|
||||
Installing Bitmessage as a daemon will increase the size of the network, and therefore the level of security for all users.

Add a user which will be specifically for Bitmessage. Since bitmessage is still a relatively young and experimental project, this adds further compartmentalisation such that if there are any bugs within PyBitmessage then an attacker can't neccessarily gain control of root or any other user account. Here we create a user called /bitmsg/ and give it a long random password.

** Install Tripwire
|

Tripwire will try to detect any intrusions into your system. It's a good idea to install it after you have installed all of the other programs which you intend to use.
