2 Agenda The problem Traditional Methods Case Study Recommendation

3 The problem

4 What is E-waste??? Electronic waste or e-waste is the rapidly expanding volume of obsolete computers, printers, fax machines, mobiles, TVs, photo copies other electronic devices Guaranteed Recycling Xperts Slide 4

5 How Much E-waste Is There? e-waste is a recent phenomenon 130 million cell phones discarded in the US in million PCs become obsolete every year in the US Environmental Production Association estimate 1.9 million tons of e-waste landfilled in 2000 (EXCLUDING electric appliances) 3 5% of material in landfills growing 3 times the rate of other waste million computers/tvs waiting in e-waste purgatory Guaranteed Recycling Xperts Slide 5

6 Where your Data is Stored? Hard Drives & Disks (ATA, USB, Zip disks, SCSI Drives, Magnetic Tapes, Floppies) CDs & DVDs cell phones, Blackberrys and other PDA Routers Copy Machines & Fax Machines

7 Private Data final destination Ref. Richard Troia i-recycle

8 Personal Record Personal Info Payment Info (e.g. Credit Card, Bank Account..etc.) Passwords Personal Correspondences Mission critical information Intellectual property Licensed software Personal Preferences/Behavior Other Personal Info (Pictures, family details, relations, medial info..etc.)

9 Business Records Today, 90 to 95% of all business records are stored in e-format & Paper represents <10% of all Business Records A single gigabyte of electronic storage has the capacity to store up to 75,000 typewritten sheets of papers. After 2 to 3 years of computer or BlackBerry use, it is easy to lose track of what information is stored and where it is located.

10 Theft of Sensitive Information 2003 MIT Student Study: 158 used hard drives 129 still worked 69 had recoverable files 49 contained credit card, medical records & personal correspondence 1 contained ATM transaction info. One of the top areas for dumping e-waste is Africa The number one area of the world for identity theft is AFRICA! Slide 10

11 Traditional Methods

12 The Benefits of Recycling the HD HDD is commonly known as Hard Disk Drive The primary device for storing all your data. One of the most expensive components in a computer (made up mostly of aluminum and other non-biodegradable materials). Provide us with highly reusable materials & protect the environment. Saving a portion of the cost associated with the laborious process by which the whole unit is assembled including the treatment of platters in order to attain a mirror finish.

13 HD recycling Barrier What happens when your info fall in the wrong hand Utilize this info (Marketing, Competitors) Identity Theft Crimes (e.g. blackmail, financial transaction)

14 Is it easy to destroy files Ways to Try to Erase Hard Drive Data Is the Data Truly Gone? Simply Delete the File Empty the Recycle Bin Format the Hard Drive Repartition the Hard Drive Installing a new operating system You need more than this!!!

15 Physical destruction Smash it with a hammer and use a hacksaw (Disintegrate & Pulverize). Grind it to dust (Incinerate). Burn it with acid. Shred Effective, if done correctly (100% destruction in 30 seconds) Makes drive inoperable Time consuming, Flying debris Can t be recycled (Not environmentally friendly) Shredders are costly and not widely available

16 Software Destruction Meaningless pattern of 0 s and 1 s convenient, and permanent Maybe inaccurate Can t be used if media is damaged Need another hard drive to run the software Consume Cost, time and resources (days or weeks for few hundreds HD)

17 Degaussing Strong electromagnetic field destroys data Machine expensive Not guaranteed to penetrate shield Hard drive cannot be reused

18 Still Recovery is possible Data Recovery Software EnCase Forensic ToolKit Examiner Many other specific use tools Data Recovery Hardware Adapters Write-blockers

19 Case Study

20 Glamorgan University Study A recent study by Glamorgan University (source: Time Online website) revealed more that 50% of 111 hard drives purchased contained personal and confidential information. Over 87% of those drives were bought from ebay. This may raises an international concern. While this is beneficial for the legitimated user, there is risk handling over our personal data to terrorists, and corrupt organizations, not to mention the risk of being blackmailed or threatened

21 Space Shuttle Columbia Hard Drive: How NASA Data was recovered after Crash

22 Timeline of Events February 1, 2003 Space shuttle Columbia disaster September 26, 2003 Ontrack Data recovery receives 3 drives recovered from debris September 29, 2003 Ontrack completes recovery of one of the disks April 17, 2008 Physical Review E publishes results of the experiment

23 Hard Drive Condition Looked like a cracked hunk of metal when it arrived for recovery. Every piece of plastic melted All chips burned and loose. Dirty and charred elements in the casing Everything but the platters were unusable.

24 Engineers worked to cut away protective top cover to get access to hard disk assembly

25 Engineers then opened the top cover of the hard disk

26 Engineers had to remove melted plastic from media and corroded, melted head assembly to remove each hard drive platter

27 Recovery Details Platters were intact, but dirty. Cleaned the platters with special chemicals. Placed in a new enclosure Replaced the damage with minor adjustment Used custom software for data transfer that includes sophisticated error handling and calculations. Recovered 99% of the data on the drive.

28 Solution

29 ATA principles of proper data destruction A Absolute: With permission to destroy a record, destroy it in a way that it can never possibly be recovered under any conditions, including forensic data recovery techniques. T Timely: Accumulation of data storage devices is a dangerous practice and should be minimized and all destruction events should take place on a scheduled basis avoiding ad hoc destruction activity that can lead to legal challenges as to the timing of the destruction event. A- Auditability: Must be able to prove that destruction activity is routine and done in good faith.

30 Monitoring & Control of Recycling firms Provide assurance Assurance Independent Audit Firms Expert Confidence Obtain confidence Proof experience Transparency Solid & Transparent work environment make someone responsible Accountability Measurability clearly defined policy

31 Consequences of Non-compliance Loss of Public Trust Loss of Business Legal Fines Cost of Mitigation

32 Market Practice Individual Promises (DELL, HP, IBM, Nokia and others) Independent Authorities (e.g. NIST - National Institute of Standards and Technology) Other legislation such as Health Insurance Portability and Accountability Act. Sarbanes-Oxley Act. Gramm-Leach-Bliley Act. (financial industry). Family Educational Rights and Privacy Act (for educational institutions). Fair and Accurate Credit Transactions Act.

33 Certifying Bodies e-stewards Initiative (e-stewards.org) The e-stewards Initiative is a project of the Basel Action Network (BAN), which is a 501(c)3 non-profit, charitable organization of the United States, based in Seattle, Washington. It is against the backdrop of the growing e-waste crisis that the e-stewards Initiative was born. Without appropriate national and international legislation or enforcement in place in many regions, it is unfortunately left up to individual citizens, corporations, universities, cities all of us to figure out how to prevent the toxic materials in electronics from continuing to cause long term harm to human health and the environment, particularly in countries with developing economies. The National Association For Information Destruction (NAID) offers a highly respected secure data destruction certification program, which helps companies to find qualified providers of secure data destruction. NAID's mission is to promote the information destruction industry and the standards and ethics of its member companies. NAID AAA Certification For Secure Data Destruction

34 Sanitization Methods Clear use software or hardware products to overwrite storage space on the media with non-sensitive data. Purge Degaussing is exposing the magnetic media to a strong magnetic field in order to disrupt the recorded magnetic domains. Destroy Disintegration, Pulverization, Melting, and Incineration Shredding.
