Paranoid Penguin - Customizing Linux Live CDs, Part II

Use encrypted folders with your custom live CD.
Using the TrueCrypt Volume with Your Live CD

And now, the moment of truth. To use your encrypted TrueCrypt volume with an Ubuntu live CD, such as the one we modified last month, simply boot a system off that CD; insert the USB drive; execute the truecrypt binary from the USB drive or from the CD, if you installed TrueCrypt on your custom image; and mount your encrypted volume, specifying a mountpoint of /home/ubuntu/Documents (Figure 4).

Figure 4. Mounting Your Volume on /home/ubuntu/Documents

If TrueCrypt prompts you for an administrative password, leave it blank and click OK. By default, the ubuntu account on Ubuntu CDs has no password.

This brings me to the topic of next month's column: further securing and customizing your encrypted-Documents-enabled live CD image. Until then, be safe!

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
