Q:

On-line security tools?

Are there tools built into "Ubuntu" (or possibly within the repositories) to help me secure my on-line information.

A:

Yes - many! You could compile and build any of the linux tools, or if you like prepackaged solutions you can use apt-get to install packages such as the following:

gpw password generator
keepass2 password safe
john password strength tool
gpg encryption

Look in the apt gui - a large list of security tools are listed there
