Tokenization: A Powerful Weapon Against Cyber Attack

Posted by on Thursday, 19 April, 2012

Tokenization in the data security world is the process of moving sensitive data from a company network to a separate location or sever, and replacing and referencing that data on the company server with a unique token.

If hackers attempt to access sensitive information like credit card numbers from a server, they’ll instead encounter the token which prevents them from finding the original data without a specific encryption key or knowledge of the tokenization system.

Linoma Software GoAnywhere Managed File Transfer SolutionFor example, say a merchant acquires a credit card number by swiping a customer’s card with a card reader.  If the merchant has implemented tokenization, this card number information is immediately replaced in the merchant’s database by a token number while the actual card number is sent and stored (in encrypted form) at a different location, along with the reference from the token.

Because the actual card number is never stored in the merchant’s front-end system, hackers have a much more difficult time stealing it. Customers can therefore be assured that it is safe to let that merchant use their card information because the actual credit card numbers are not stored in an easily accessible location.

All organizations that capture credit card data are required by the PCI DSS government regulations to secure and protect this data.  Originally, this presented a challenge to the payment industry until Shift4 Corporation presented tokenization solutions at an industry Security Summit in 1995.  The adoption of tokenization became a popular solution to meet the PCI DSS compliance regulations.

Other industries are beginning to adopt tokenization to protect confidential information such as banking transactions, medical records, criminal records, vehicle driver information, loan applications, stock trading and voter registration.

Finding the most efficient way to implement tokenization is challenging, but the growing threat of cyber attack and the expense of data breach have motivated IT shops to research options in earnest.

A variety of third-party software solutions, such as Linoma Software’s Crypto Complete, deliver tokenization tools as well as additional options for managing encryption keys, audit logs, message alerts; storing tokenized data; automatically assigning token identifiers; and providing a central management platform for the entire tokenization process.

When a greedy hacker in anticipation of scoring a cache of customer credit card data finds instead a series of tokens, companies win another battle in the war against cyber thieves.

Citigroup Breach Triggers Congressional Response

Posted by on Monday, 11 July, 2011

The data breach at Citigroup in May – a breach which reportedly exposed an estimated 200,000 customer accounts – has motivated members of the U.S. Congress to re-introduce legislation to penalize the very organizations that have been victimized by hackers.  What are the next steps your company should take?

New bills to protect consumers’ personal dataLinoma Software Managed File Transfer Solutions

Two bills are proposed by both House and Senate legislators.

First, Sen. Patrick Leahy (D-Vt.) has introduced the Personal Data Privacy and Security Act of 2011.  The new bill provides:

  • Tough criminal penalties for individuals who intentionally or willfully conceal a security breach involving personal data;
  • A requirement that companies that maintain personal data establish and implement internal policies to protect data privacy and security; and
  • A requirement that the government ensure sensitive data is protected when the government hires  third-party contractors.

This act would also require, under threat of fine or imprisonment, that businesses and agencies notify affected individuals of a security breach by mail, telephone or email  “without unreasonable delay.” Media notices would be required for breaches involving 5,000 or more people.  The FBI and the Secret Service would need to be notified if the breach affects 10,000 or more people, compromises databases containing the information of one million or more people, or impacts federal databases or law enforcement.

But that’s not the only security bill that has businesses concerned.

In the House, Rep. Mary Bono Mack (R-Ca) is holding hearings in preparation of a bill she’s named The SAFE (Secure and Fortify) Data Act that would also require “reasonable security policies and procedures” to protect consumers and enable disclosures to victims and the Federal Trade Commission within 48 hours of a data breach.

Companies no longer viewed as the victims

All this sounds good from the consumer’s point of view. But what about the expense – and potential Linoma Software GoAnywhere Managed File Transfer Solutionpenalties – suffered by the “owners” of the data: the businesses themselves?

While these bills may address the public’s interest for notification — and indeed they would bring some semblance of a national standard – they also represent an interesting shift in the liabilities that companies will face.  How is that?

Though we currently have no federal data breach notification law, federal policies now view the companies that experience a data breach as the victims of crime. However, under the proposed legislative bills, companies that do not act quickly to appropriately secure the personal data of customers – or fail to report a data breach in a reasonable amount of time – would not only suffer the theft of data, but also be held liable for its loss.

This is a significant shift. Companies are now being viewed not as the owners of consumer data, but merely guardians and trustees whose job it is to protect that data or face criminal penalties. And the message is clear: if companies won’t take adequate precautions to secure the sensitive data of our customers, they’ll pay a hefty price.

Where does your company stand?

In a world in which diligent hackers have the power break into seemingly secure networks and systems, what can your company do?

The challenge is first to determine exactly what qualifies as adequate precautions.

GoAnywhere Secure Managed File Transfer A review of the HIPAA HITECH security provisions that took effect last year provides some insight about what the government considers adequate protection.

HITECH strongly recommends the use of encryption technology. Encryption is a good place for your company to start, especially when dealing with the data your company stores on its servers.  If sensitive data itself is kept securely encrypted, a data breach doesn’t expose the content of the information itself.

Secure managed file transfer protocols – which send data using encryption – is the second place to focus attention.

If data is encrypted when it is being securely transmitted between business partners, the value of that data should it be breached – through hacking, theft, or other malicious actions – is worthless.  Encryption and secure managed file transfers can dramatically minimize the holes of technical breaches, significantly reducing an organization’s liability.

Preventing exposure

The Citigroup data breach has rekindled the momentum for a nationwide, cross-industry data breach reporting standard. This standard will not to eliminate the physical breaches themselves. What’s needed is legislation to encourage companies secure the underlying data that is the target of the hackers.

Isn’t it time for your company to take a serious look at its liabilities and to investigate how encryption and managed file transfers can close these important security holes?

Top 10 Healthcare Data Breaches in 2010

Posted by on Monday, 6 June, 2011

Most data breaches are caused by simple acts of carelessness.

Last March the Ponemon Institute released its findings for the 2010 Annual Study: U.S. Cost of a Data Breach. The study — based on the actual data breach experiences of 51 U.S. companies from 15 different industry sectors — revealed that data breaches grew more costly for the fifth year in a row. They jumped from $204 per compromised record in 2009 to $214 in 2010.

The increase in cost, however, pales in comparison to the reputational cost of companies that have been victimized, particularly in the healthcare sector.

HITECH builds Wall of Shame

Consider that the U.S. Department of Health and Human Services has begun posting the data breaches affecting 500 or more individuals as required by section 13402(e)(4) of the HITECH Act.  The New York Times has labeled this site “The Wall of Shame”.  Why? Because if patients have no faith in electronic record-keeping, the future of healthcare record automation will be jeopardized: Law suits and government regulation will bury any cost-savings.

The Back Stories of Healthcare Data Breaches

What are the stories behind the most severe healthcare sector data breaches reported in 2010?  Here are the ten most expensive stories, in ascending order of cost, documented in the Privacy Rights Clearing House database. While they’re sober reminders of the problem of keeping data secure, they’re also instructive: none of these breaches were malicious hacks, but were instead the results of theft, poor record-keeping policies, and simple human error.

(Note that the estimate of liability uses the $214/ record cost identified by the Ponemon Institute in its annual report. We have purposely not published the names of the reporting institutions.)

10th Most Expensive: Physician Computer Theft Exposes 25,000

On June 29th of 2010 a thief stole four computers from a physician specialist’s office in Fort Worth, Texas.  This theft resulted in an estimated 25,000 patient records being exposed.  The patient records contained addresses, Social Security numbers and dates of birth. Estimated liability: $5,350,000.

9th: Medical Center Theft Exposes 39,000

On the weekend of May 22nd, 2010 two computers were stolen from a medical center in the Bronx. Names, medical record numbers, Social Security numbers, dates of birth, insurers, and hospital admission dates of patients were known to be on the computers.  Total records compromised: 39,000. Estimated liability: $8,346,000.

8th: Optometrist’s Computer Theft Exposes 40,000

A computer stolen from an Optometry office in Santa Clara, California on Friday April 2nd, 2010 contained patient names, addresses, phone numbers, email addresses, birth dates, family member names, medical insurance information, medical records, and in some cases, Social Security numbers. Though the files were password protected, they were not encrypted.  A total of 40,000 records were lost, with an estimated liability of $8,560,000.

7th: Medical Records Found at Dump Expose 44,600

Medical records were found at a public dump in Georgetown, Massachusetts on August 13th, 2010. The records contained names, addresses, diagnosis, Social Security numbers, and insurance information. A medical billing company that had worked for multiple hospitals was responsible for depositing the records at the dump. The exposure required the hospitals to notify patients – an effort that continues to this date.  The total number of records known to have been exposed is 44,600, but the search continues.  Estimated liability: $9,544,400.

6th: Consultant Laptop Stolen Exposing 76,000

On March 20th, 2010, in Chicago, Illinois, a contractor working for a large dental chain found his laptop stolen.  The computer held a database containing the personal information of approximately 76,000 clients, including first names, last names and Social Security numbers. Estimated liability: $16,264,000.

5th: Lost CDs Expose 130,495

On June 30th, 2010 a medical center in the Bronx reported that it had failed to receive multiple CDs containing patient personal information that was sent to it by its billing associate.  These CDs were lost in transit. Information of 130,495 patients included the dates of birth, driver’s license numbers, descriptions of medical procedures, addresses, and Social Security numbers.  Estimated liability of $27,925,930.

4th: Portable Hard Drive Theft Exposes 180,111

In Westmont, Illinois, a medical management resources company reported on May 10, 2010 that a portable hard drive had been stolen after a break-in.  The company believes the hard drive contained personally identifiable information about patients including name, address, phone, date of birth, and Social Security number. The company acknowledged that this hard drive had no encryption.  As a result, 180,111 records were exposed, creating an estimated liability of $38,543,754.

3rd: Leased Digital Copier Leaks 409,262

On April 10th, 2010 a New York managed care service in the Bronx reported that it was notifying 409,262 current and former customers, employees, providers, applicants for jobs, plan members, and applicants for coverage that their personal data might have been accidentally leaked through a leased digital copier. The exposure resulted because the hard drive of the leased digital copier had not been erased when returned to the warehouse. Estimated liability: $87,582,068.

2nd: Training Center Hard Drive Theft Center Exposes 1,023,209

The theft of 57 hard drives from a medical insurance company’s Tennessee training facility in October of 2010 put at risk the private information of an estimated 1,023,209. customers in at least 32 states. The hard drives contained audio files and video files as well as data containing customers’ personal data and diagnostic information, date of birth, and Social Security numbers, names and insurance ID numbers. That data was encoded but not encrypted. Estimated liability to date: $218,966,726.

Most Expensive of 2010: Two Laptops Stolen Exposes 860,000

A Gainsville, Florida health insurance company reported in November of 2010 that two stolen laptops contained the protected information of 1.2 million people.  This is an on-going story, as new estimates are calculated.  To date, the estimated liability is $256,800,000.

Preventing Exposure: Data Encryption

These cases document that the majority of the data breaches which occurred in 2010 were not the result of hacking activities, or even unauthorized access by personnel. The greatest data losses were simply the result of computer theft of portable devices and misplaced media.  Had the contents of the files been encrypted, this could have significantly reduced the risks and liabilities of these data losses.

Time and time again, industry experts point to data encryption as the key method by which organizations can prevent inadvertent exposure of sensitive data.

Of course, no healthcare organization wants to be listed on the US Department of Health and Humans Services’ Wall of Shame.  And the costs – in dollars and in reputation – can be extraordinary.

Isn’t it about time your management got serious about data encryption?
