Introduction
Statistical database security will be the focus of the research
proposal. Because statistical data is used to answer statistical
questions about an organization's performance, it should be kept
private for any given organization. Private information could
fall into the hands of those wishing to harm the organization's
employees or customers in the event of a data breach. To
protect the confidentiality of sensitive transactional data,
statistical databases must be safeguarded. “Database Security
Technical Implementation Guide, states that database security
should provide “controlled, protected access to the contents of
your database and, in the process, preserves the integrity,
consistency, and overall quality of your data” (p. 9). The goal is
simple, the path to achieving the goal, a bit more complex.
Research Statement
The primary goal of statistical database protection is to ensure
data privacy while minimizing data loss. The most pressing
concerns for data owners are access to reliable and unlimited
data and ensuring that publicly disseminated information is kept
private. ‘database security encompasses three constructs:
confidentiality or protection of data from unauthorized
disclosure, integrity or prevention from unauthorized data
access, and availability or the identification of and recovery
from hardware and software errors or malicious activity
resulting in the denial of data availability.’ Because these two
actions are mutually exclusive, high-quality data must be
protected from both disclosure and identification.
Event Analysis
To keep statistical databases safe from intrusion, two methods
are used. Restriction means that the organization will only

9. present statistical data that has been deemed safe, whereas noise
addition means that data will be available as estimates rather
than exact figures. These two methods are critical for
determining whether or not data has been lost or stolen.When a
snooper is determined to obtain classified information about a
specific element, threats to statistical data arise. In a situation
like this, private information will likely be made public. When
snoopers derive filtered estimations of interest and exact
assessments of private values from the responses, one or more
statistical inquiries can lead to exposure.
Top Statistical Databases Threats
Most statistical databases can be easily abused and manipulated
by an overly powerful employee. This is more likely to occur
when employees' supervisors or managers grant them database
privileges that go above and beyond what their job descriptions
require. “Today's information security battleground is all about
entitlements – who’s got them, whether they were granted
properly, and how to enforce them” (p.117). Being able to
assess access control techniques is critical to student
understanding of database security. Bank employees can easily
increase or decrease customers' account balances and changes
their account information. It's not uncommon for businesses to
fail to update employees' access privileges when they change
departments or even leave (Murray, 2016). Malicious employees
have also taken over statistical databases and used them for
their gain. These employees commit illegal acts by abusing the
privileges bestowed upon them by their positions of authority
within the database.
Strategies to Protect Statistical Databases
Each sensitive statistical database should be kept separate from
the others. An accurate inventory of all statistical databases that
should be used throughout the company can assist in meeting
this goal. This can be used to identify sensitive data if it is
stored in these databases. Following that, all security flaws
must be addressed. The system administrator in question must
be actively involved in the ongoing assessment, identification,

10. and remediation of any vulnerability in the statistical database
in question.
