Skill Level Beginner
- [Facilitator] Welcome to this course on the protection and destruction of portable data. My name is Jennifer Kurtz. I lead graduate courses in cybersecurity and strategic project management for health care professionals at Regis University in Denver, Colorado. Writing the chapter on data leakage prevention, or DLP, technology for the American Bar Association's Data Breach and Encryption Handbook led me to further exploration of privacy issues that I had started while doing graduate studies at Purdue University.
Exposure of confidential or sensitive data stored on portable devices is a deep concern. True confession: I am a digital hoarder. I still have floppy drives, the true consumer-grade floppy drives. The five and a quarter inch wonders that let me store 360kb of data. 360,000 bytes, wow! As a reference point, a low-resolution 72-pixel per inch photo is about 182 kilobytes.
It won't even show well on a retinal display. I also have all 32 3.5 inch not-so-floppy high density drives that were required to load MS Office on my 1990s vintage laptop. A big change in highly portable data storage arrived in 2000 with IBM's release of its eight megabyte flash drive. These little marvels kept getting better, and cheaper. The eight megabyte Disk on Key cost $45 in 2001.
In fewer than 16 years, an eight-gigabyte drive costs around $10. A gigabyte is 1,000 times larger than a megabyte. The math is easy. 1,000 times the storage for 78% of the price. Amazing when you think about it. If we want to go less portable today for storage media, say, something larger than one inch by one and a half inches, but that still weighs under six ounces, we can buy a terabyte of external hard drive storage for about $60.
A terabyte is 1,000 times larger than a gigabyte. Lots of photo storage opps. As storage has become cheaper and more convenient, or smaller, digital hoarding is easier to justify. It also means that we have more data storage that is easily lost or misplaced, and perhaps not well indexed. This easy data storage has changed how, or at least what, we remember. We rely on our portable data memories. In this course, we will explore how we can protect our portable data that is at risk.
We will also learn how we can destroy our portable data that we no longer need, so that others cannot make use of it beyond our control. We will examine portable data within different use scenarios. In addition to personal use, we will look at portable data use in different sectors: public or government, medical, commercial and retail, and financial. In this lesson, we have looked at how portable data storage containers have shrunk in physical size and in cost, and yet expanded in storage capacity.
Next, we will discuss how disturbing it is to lose important portable data. We will also list some common places where we store this data. Anyone who has ever experienced data loss, or is concerned about such a loss, should find this course useful.
