Dear Windows XP, Congratulations on your retirement

Posted 04/08/2014 - 07:42 by David Schnardthorst

Well, today is the day you have been looking forward to for years, the day you get to finally retire. You have had the opportunity to touch people around the world, sometimes helping them and sometimes scarying them with such things as the Blue Screen of Death.

You have been a key player in starting new businesses, you have taken up residence in millions of homes, you had some good days, and you had some bad. You will find that many will have a really hard time letting go and will continue to try to use you, so don't think you are going to get away so easily.

What is PCI-DSS and why should I care

If you accept Credit / Debit cards then you have probably heard of PCI-DSS. While many larger organizations have heard about and understand the importance of PCI-DSS, many smaller organizations do not understand what it is and why it is important. In fact, when it comes to many small medical offices, for example Chiropractors, Dentists and Family Practitioners, the main focus is HIPAA compliance. But, if these offices accept Payment Cards they must also comply with PCI-DSS.

How to securely wipe a hosted Linux VM

Let's face it, cloud computing has become a popular option for many companies. However, managing compliance in the ever-changing world of cloud computing is difficult. One such difficulty is how to securely wipe a disk on a cloud server. There are many options still available, but one best practice we have found is to us 'dd' to write over the disk partition(s).

  dd if=/dev/zero of=/dev/disk/volume
This essentially does a single-pass over the disk volume writing zeroes to replace the existing data.

Tell me your thoughts

Do you have another option for wiping disks in a Cloud Based environment? How would you approach this?
