breaches | R Documentation |
data.frame
of cyber security breaches
involving health care records of 500 or more
humans reported to the U.S. Department of
Health and Human Services (HHS) as of June
27, 2014.
data(breaches)
A data.frame
with 1055 observations on
the following 24 variables:
integer record number in the HHS data base
factor
giving the name of the
entity experiencing the breach
Factor giving the 2-letter code of the state where the breach occurred. This has 52 levels for the 50 states plus the District of Columbia (DC) and Puerto Rico (PR).
Factor giving the name of a subcontractor (or blank) associated with the breach.
integer
number of humans whose
records were compromised in the breach. This
is 500 or greater; U.S. law requires reports
of breaches involving 500 or more records but
not of breaches involving fewer.
character
vector giving the
date or date range of the breach. Recodes
as Date
s in breach_start
and breach_end
.
factor
with 29 levels giving the
type of breach (e.g., "Theft" vs.
"Unauthorized Access/Disclosure", etc.)
factor
with 41 levels coding the
location from which the breach occurred (e.g.,
"Paper", "Laptop", etc.)
Date
the information was posted
to the HHS data base or last updated.
character
vector of a summary of
the incident.
Date
of the start of the
incident = first date given in
Date_of_Breach
above.
breach_end
Date
of the end of the incident
or NA
if only one date is given in
Date_of_Breach
above.
year
integer
giving the year of the
breach
The data primarily consists of breaches that occurred from 2010 through early 2014 when the extract was taken. However, a few breaches are recorded including 1 from 1997, 8 from 2002-2007, 13 from 2008 and 56 from 2009. The numbers of breaches from 2010 - 2014 are 211, 229, 227, 254 and 56, respectively. (A chi-square test for equality of the counts from 2010 through 2013 is 4.11, which with 3 degrees of freedom has a significance probability of 0.25. Thus, even though the lowest number is the first and the largest count is the last, the apparent trend is not statistically significant under the usual assumption of independent Poisson trials.)
