Hurricane between Florida and CubaHurricane season is in full swing.  As I write this, Tropical Storm Emily is drenching Florida, and the governor has declared a state of emergency.  Having lived in Florida myself, I know that most coastal residents do take hurricanes seriously.  There are always those, however, who either don’t grasp the possibility that if a hurricane hits they can suffer real damage, or simply play the odds that it won’t happen to them.  Hurricane readiness for them is a bottle of Cuervo Reserva and some DVDs for entertainment in case the power goes out.  And so, too, it goes with data breaches.

Breach readiness today ranges from total denial, through half-hearted attempts at maintaining current backups, to—for a minority—sophisticated IT security teams and technology ready to detect, respond, and recover.  Even the technologically prepared, though, have likely not planned beyond containment and recovery.  Consider our hurricane scenario.  Minimal readiness includes necessities for riding out the storm: an evacuation plan, water, food, flashlights, medical supplies, and so on.  Those things should get you through the first 48 hours, much like the immediate IT response to a data breach.  But what next?Continue Reading It’s readiness season

Business woman screaming at laptopMany years ago, before common sense kicked in, I thought it would be a good idea to rent a storage space for all the extra furniture and other stuff I could not fit in my new house.  Knowing it would only be temporary, I stashed everything from upholstered and leather furniture, to boxes of books.  Fast forward twelve months.  The rental agreement was expiring, and I realized that I would never need nor have room for all that I’d stored, so I decided to have a sale to dispose of it.  When I went to the storage space I was horrified to see that everything was covered in a thin film of mold.  (This was years before climate-controlled storage was widely available.)  I had no choice but to trash it all, which both cost me money and prevented me from converting my goods to profit.

I was reminded of this long-ago event when I heard about the latest ransomware attack.  We’ve been reminded countless times of the importance of backup, and ransomware is only the most recent reason.  If you have ever had a hard drive fail, you know the pain that comes with irretrievable data.

So what happens when your backup media fails.? Or your archival media?  Don’t CDs last forever?

checklistIt’s a common complaint – most U.S. laws requiring data security never cough up the specifics of what must be done to comply. Unlike other areas of business regulation, data security requirements seem hopelessly vague:

  • Several states’ PII laws require businesses to implement and maintain “reasonable security procedures and practices” to protect PII from unauthorized access, destruction, use, modification, or disclosure.
  • Regulations under the Gramm-Leach-Bliley Act compel financial institutions to have a “reasonably designed”comprehensive information security program with administrative, technical, and physical safeguards to protect the security, confidentiality, and integrity of customer information.
  • FACTA regulations require that consumer report information be disposed of “by taking reasonable measures to protect against unauthorized access to or use of the information….”
  • HIPAA covered entities and business associates must address the security standards for ePHI in a way that protects against “reasonably anticipated threats or hazards” to ePHI security or integrity.
  • The FTC enforces reasonable data security under Section 5 of the FTC Act, which prohibits unfair and deceptive acts in commerce, without explicitly mentioning data security and without any supporting regulatory standards for specific data safeguards.

Obviously, we can’t just put “remember to have reasonable data security” in a compliance checklist or internal audit protocol, because “reasonable” tells us nothing concrete about what specific security controls are needed to be compliant.  So, why do these laws stop short of telling us specifically what to do?

Lawyer holding a target on his faceWhile preparing for an upcoming presentation for in-house lawyers on data security, I dusted off the events of three months ago, when Yahoo! Inc. unceremoniously fired its general counsel on March 1st, the very same day it filed its 10-K for fiscal year 2016.  Yahoo’s 10-K disclosed the contemporaneous dismissal as a “Management Change” resulting from its Board of Directors’ Independent Committee investigation into Yahoo’s immense 2013-2014 data breaches, which were not disclosed until 2016. Unlike prior mega-breaches, in which the head of IT or the CEO was let go (Target, Sony), Yahoo singled out its lead in-house lawyer for firing … without separation compensation of any kind.

Henceforth, whether fairly or not, March 1 will be known as In-house Counsel Data Security Awareness Day – because it’s now clearer than ever before that in-house lawyers must take a hands-on approach to breach response, breach response readiness, and data security generally.Continue Reading In-house Counsel in the Cybersecurity Crosshairs

… wMan with starting pistol over a background of ready racersell, not quite that fast.  But nine minutes is pretty quick, as FTC researchers recently confirmed.

The FTC’s Office of Technology Research & Investigation (OTech) ran an experiment in April and May, posting made-up personally identifiable information in plain text on two different Internet paste sites.  The phony PII was consumer account information for 100 fictitious people, including name, address, phone number, email address, password, and payment means (credit card number, online payment account, or Bitcoin wallet).  Then, OTech waited to see what would happen, monitoring for access attempts on email and payment accounts, attempted credit card charges, and calls and texts received.

The results, and the speed of those results, were a surprise to all but the most jaded.  Here’s what OTech’s monitoring revealed:Continue Reading How quickly is stolen PII fraudulently used? Faster than you can tweet “covfefe”

dominoes fallingSometimes one must look past the headlines (Target’s $18.5 million deal with the states) to see what’s truly important in effective data breach response.

Last week, in the Experian data breach litigation, the District Court denied plaintiffs’ motion to compel production of the forensic analysis report on the breach, prepared by Mandiant.  Why?  Because it was Experian’s law firm that retained Mandiant to perform the forensic analysis and prepare its report, in anticipation of litigation.  According to the court:

  • Jones Day hired Mandiant to assist the law firm in providing legal advice to the client Experian;
  • Mandiant’s report was based on server images that are independently discoverable, without the report;
  • only a summary, not the full report, was shared with Experian’s internal Incident Response Team; and
  • though Mandiant had in the past worked directly for Experian on other matters, this engagement was separate.

On this basis the court held that the report was protected work product, without even reaching the additional point of attorney/client privilege.

So what’s the big deal?  It’s this – in the heat of an unfolding security incident (in Experian’s case, impacting 15 million people), things move fast.  Really fast.  Victim companies scramble to understand what happened, when it happened, what must now be done, and by when. The what and when are of course important, but  so too are the who and how of effective breach response.  For example, a natural move under the gun is to have the infosec folks immediately bring in an outside security/forensics firm and turn them loose.  Sounds great … until litigation ensues, and all of the forensic firm’s analysis is fair game in discovery – the good, the bad, and the ugly.

This is a no-win situation, for both the unprepared and the semi-prepared:

Ransomware - Ransomnote on ComputerI hope you were not affected by last Friday’s WannaCry ransomware hack.  If you were, you are unfortunately part of the biggest on-line extortion scheme seen to date.  And it may not be over, as new variants are appearing, so although you may have dodged the bullet for now, experts suggest that this attack is “nothing compared to what might be coming.”  So who are the lucky ones whose data is safe?

Verizon 2017 DBIRI always look forward to Verizon’s annual Data Breach Investigations Report.  Verizon dropped the 2017 DBIR last week, and for the 10th year in a row it cuts through the confusing landscape of security incidents and data breaches with analysis, alacrity … and yes, attitude (in what other report can you find a paragraph heading like “Tall, Dark, and Ransom”?).

The 2017 DBIR distills global information from 65 collectors of incident and breach data, analyzing 42,120 security incidents and 1,925 breaches that occurred during 2016.  The threat environment changes each year, but one of the reasons I value the DBIR is that it shines a light on a few key things that don’t change.  Here are four central aspects of data security that endure – and which we forget at our peril:Continue Reading Yipee – Verizon’s 2017 DBIR has arrived!

Adding piece to jigsaw puzzleEffective June 16, New Mexico will be the 48th state with a PII data breach notification statute.  New Mexico joins the vast majority of states, plus the District of Columbia, Puerto Rico, Guam, and the U.S. Virgin Islands, in requiring notice to affected residents of PII security breaches – as of June, only Alabama and South Dakota will lack such a law.

Like other states’ statutes, New Mexico’s new law is triggered by the residency of the affected individuals, and so companies across the country with PII of New Mexico residents must now fold the New Mexico requirements into both their PII policy definitions and their breach response protocols.

So, how does New Mexico’s new statute fit into our perplexing puzzle of PII breach notification laws?Continue Reading America’s great – New Mexico makes 48

Breach VennI wish I had a bitcoin for every time I get an email with the subject line “Data Breach,” yet the facts upon investigation reveal no notifiable breach occurred.

In the Venn diagram of cyber security, the big rectangle is security incidents, enveloping a smaller circle of incidents that are breaches under state PI breach notification statutes.  And a yet smaller circle are the breaches for which these statutes require notification of affected individuals.

So, what are common scenarios in which a security incident does not trigger notification duties under state PI breach notification statutes?Continue Reading When is a “data breach” not a breach?
