Key Security Questions For Healthcare Executives:
What to Ask and Answer Before Implementing the HIPAA Security Rule
By Clyde Hewitt and Bill Miaoulis, CISA, Principals, Phoenix Health
Systems
Though many healthcare executives are sighing in relief with the
passing of the April 14, 2003, HIPAA Privacy Rule deadline, they
now face new challenges posed by the final HIPAA Security Rule.
Published in February, the long awaited security regulations require
compliance by April 21, 2005. Many forward-thinking organizations
have a good head start by prudently initiating security measures
needed to safeguard patient privacy, but few are in a position to
claim full compliance with the comprehensive new Security Rule.
To a great extent, the Security Rule puts the HIPAA spotlight back
on Chief Information Officers (CIOs) and Information Systems managers
to develop and implement cost-effective enterprise-wide security
programs. However, the entire senior management team should play
an important strategic planning role before practical measures are
implemented. As healthcare organizations look toward developing
annual budgets, the executive team should be asking such questions
as:
"What are the security risks to my organization - and which
are the highest priority?"
"What measures should be considered for our plan to reduce
risk and become HIPAA Security compliant?"
"How much should we budget (money, resources) for security?"
In order to answer these questions, both the short term and long
term impacts of the HIPAA Security Rule must be evaluated, with
a focus on the organization's most important high risk areas. In
many organizations, it is likely that twenty percent of the issues
will determine eighty percent of the cost.
First Steps in Risk Analysis and Security Planning
Beginning the process of risk analysis and security planning requires
a critical eye and careful planning. It is a mistake to jump to
conclusions about what needs to be fixed before the problems are
fully understood.
The HIPAA Security Rule requires covered entities to have a risk
management program in place to evaluate the value of the assets,
the potential for a loss or disclosure, and the cost of additional
countermeasures. The NIST 800-30 Risk Management Guide for IT Systems
outlines a process for determining the return on investment for
security measures, based on the following factors:
- The likelihood of a given threat-source's attempting to exercise
a given vulnerability
- The magnitude of the impact should a threat-source successfully
exercise the vulnerability
- The adequacy of planned or existing security controls for reducing
or eliminating risk
The NIST approach may be adequate for a risk management program
focusing only on IT systems, but the scope of the HIPAA Security
Rule encompasses more than IT. Executives should also look at threats
to all of the organization's assets including programmatic threats
caused by staffing and budgeting shortfalls.
The following checkpoints can help guide senior executives through
the initial phases of developing an appropriate security program
for their organization. You may want to employ an external security
firm to perform vulnerability and penetration studies on your network
and computer systems to support this process.
What are your most important security risks?
Before developing a protection strategy, the management team must
first define what is worth protecting. HIPAA and good business practices
dictate that we safeguard patient information entrusted to us. To
be sure, the relative importance of tangible and intangible assets
depends upon the view of the ranker, but it can be argued that senior
staff in most healthcare organizations will include many, if not
all, of the following in their lists of important security risks:
- Loss of financial cash flow
- Permanent loss or corruption of electronic protected health
information (ePHI)
- Temporary loss or unavailability of medical records
- Unauthorized access to or disclosure of ePHI
- Loss of physical assets (computers, etc.)
- Damage to reputation and public confidence
- Threats to patient safety
- Threats to employee safety
Note that the final HIPAA Security Rule follows the philosophy
of the proposed rule, in that it specifically focuses on "electronic
Protected Health Information." Consider for a moment the medical
records stored in an MRI or CT scanner. What about the ultrasound
or EEG recorders? These exemplify the many less-than-obvious areas
of risk to ePHI that could be accidentally disclosed, lost, or corrupted.
> Loss of financial cash flow
Without cash, the organization cannot function. Cash flow disruption
can be caused by many factors, but the inability to record charges
and bill for services due to a loss of data processing capabilities
is certainly a risk that all organizations face. Security has been
compared to a three legged stool of integrity, availability and
confidentiality. Using this definition, security includes ensuring
that systems are available, and the HIPAA security rule requires
contingency planning and disaster recovery plans. What would be
the financial impact of a loss of data processing capabilities?
Could a loss of data processing capabilities that lasted 30 days
have a major impact on your financial cash flow? What other risks
exist in your organization that might impact financial cash flow?
Do you have a risk with regards to the HIPAA Transaction and Code
Set requirements?
> Permanent loss of ePHI
Access to accurate patient information is critical in keeping a
health care organization operational. Destruction or corruption
of ePHI, particularly on a major scale, would be catastrophic for
any healthcare enterprise. Examples of threats that could destroy
or corrupt ePHI include a natural disaster such as a fire, an external
hacker attack that destroys data on your computers, or a rogue programmer
that creates code that corrupts not only the live data but your
backup tapes as well. While downtime procedures may provide a relative
short-term workaround solution, the total loss or corruption of
patient data will be nearly impossible for many organizations to
recover from.
Are your backup procedures adequate? How much data would be lost
if a tornado completely destroyed your data center? Unless you have
redundant data at another location the answer will depend on the
time of day, and is likely to range from one hour to 28 hours of
data. How would your organization recover from losing the last 28
hours of data such as lab results, hospital charges, radiology results,
orders, etc.?
> Temporary unavailability of ePHI
The temporary loss or unavailability of medical records containing
ePHI can severely delay or impair care services and business operations.
Examples of this could be as simple as a hard drive crash, a snow
storm knocking out power to computers or malfunctioning of an application
system. When was the last time you had an unplanned downtime? Many
organizations have developed downtime procedures that can be used
while networks are restored or backups are reloaded. These events,
while disruptive, likely will not permanently scar a healthcare
organization if there has been no permanent loss of data.
However, healthcare executives need to ask what would be the impact
if computers go down for 2 hours, 6 hours, 24 hours, 48 hours, 1
week, 2 weeks, 4 weeks, etc.? How would you recover and re-enter
data lost since the last backup tapes were created?
> Unauthorized access to or disclosure of ePHI
Now that the HIPAA Privacy regulations are in effect, unauthorized
access to or disclosure of ePHI (confidentiality) must be on the
list of every healthcare organization's important security risks.
Many aspects of poor security can increase this risk and the HIPAA
security rule focuses on reducing this risk. Terminals that do not
have adequate timeout functions could allow an unauthorized user
to gain access to ePHI. Inadequate audit trails and monitoring can
create an environment whereby employees have unauthorized access
to the ePHI of their neighbors, family members or co-workers.
Other organizations may have adequate audit trails but refuse to
enforce sanctions on employees that breach security or privacy,
thereby creating major risk to patient confidentiality. Add to this
the very real risk of civil and criminal penalties, and the potential
loss of reputation and credibility that may result from unauthorized
disclosures or access.
What has your organization done to ensure proper ePHI access and
disclosures? Could you defend yourself in court? Would you be able
to answer if asked what your staff is doing to protect patient privacy?
Are your security policies and procedures assisting you in ensuring
patient confidentiality?
> Harm to reputation and public confidence
Many organizations rank their organization's reputation and the
confidence of their patient/client base as a highly valuable asset
worth protecting. It is often difficult to put a dollar value on
such intangibles. Further, loss in reputation presents a special
security challenge, since it is normally predicated by some other
loss or potential loss such as a major patient security breach that
can occur from an internal (employee) or external (hacker) threat.
It is also the hardest asset to reacquire once it is tarnished.
Does your organization have a process in place to minimize and/or
offset damage in the event of a major security or privacy incident
that could tarnish your reputation?
> Loss of or damage to physical assets
The loss of assets such as computers, routers, firewalls, laptops
and other equipment can be very disruptive, but recovery may be
manageable through procurement of adequate insurance and providing
for contingency plans. The most important risk may be that such
a loss could have a critical impact on other areas, especially the
loss of data processing capabilities. What impact could the theft
of a laptop have on your organization? To answer this question we
must know what data is on the machine, how this data is protected
(encryption, passwords) and does this equipment have dialup or VPN
capabilities to access our main systems. What steps would your organization
take if a laptop was stolen? What steps would you take if critical
lab equipment malfunctioned?
What are you doing to protect your most important equipment? Do
you know what equipment is vital to your organizations ability to
deliver quality patient care and protect cash flow? Do you have
documented security response procedures?
> Compromise to patient safety
Protecting the safety of patients is a critical risk that must
be considered. One scary scenario would be a rogue programmer who
changes lab values that physicians use to treat patients. A program
that alters the potassium level of every 100th patient could create
misdiagnosis that could injure or kill patients. Do you have adequate
application program change control and monitoring procedures to
protect against such an event? What are your organizational policies
and procedures for ensuring the integrity of the data in your organization?
Physical security with regards to ePHI is an important component
of the HIPAA standards. Ensuring the safety of your patients through
physical means is also a security risk that your organization should
consider. Do you have adequate controls in your facility? Are you
located in a high crime area and have the need for metal detectors
at the Emergency Department entrance? Could a gang member come to
your Emergency Department to finish the job? Are you appropriately
protecting newborn babies in your facility?
As required by the Privacy Rule, are your opt-out procedures adequate
to ensure that an abused spouse cannot be found in your facility
by her abuser? Do you have printed reports at the information desk
that contain this information? Have you trained all staff including
the nursing unit employees to not give this information to someone
that has opted-out?
> Compromise to employee safety
One asset that is sometimes forgotten in risk management planning
is physical risk to the organization's staff. Depending on the local
availability of skilled labor, the impact of a loss of staff members
will vary widely. Considering the growing threats of bioterrorism
and weapons of mass destruction, threats to these "people power"
assets must be considered.
What steps are you taking to protect your staff from physical harm?
In the event of a major disaster in the area (e.g., hurricane) how
could you assist your employees in safely showing up to work? Is
your parking deck secure or do you need to offer escorts during
certain hours?
Where are the organization's assets?
The development of a successful, HIPAA-compliant security program
requires that all ePHI be located and protected. EPHI may exist
throughout a provider's facilities, on individual workstations,
laptops, biomedical devices, paper charts, PDAs or departmental
servers. The most likely concentration of ePHI will be in the Information
Systems department, resident on servers or mainframe computers.
However, the search should also include biomedical engineering,
radiology departments and all areas of your facility that may maintain
ePHI.
Providers should also be on the lookout for external risk factors.
One example might be a critical software vendor that won't meet
the minimum security requirements by the compliance date.
Also consider Business Associates and other members of an Organized
Health Care Arrangement (OHCA), if applicable, for assets requiring
protection. If one of these businesses allows an adverse event with
your organization's ePHI to occur, then it will be difficult to
avoid the consequences of association. An example of this would
be sending billing information electronically to a third party billing
companies whose system is breached and your patient's ePHI is compromised.
The HIPAA security rule adds additional language and requirements
for Business Associates.
Do you know where your data is? How comfortable do you feel with
regards to data you entrust to a business associate? Are your vendors
committed to ensuring necessary security safeguards? Have you modified
your Business Associate agreements in light of the new security
requirements?
What agents will create potential threats?
An "agent" of a security threat is usually an individual
who wishes to do harm against one or more of the organization's
assets (or who inadvertently creates harm). An exception is natural
disasters such as fire, floods, hurricanes, etc., which also act
as agents of asset damage or destruction. The list of potential
agents that could target your assets and take advantage of potential
vulnerabilities are employees (the most common agent), ex-employees,
hackers, commercial rivals, terrorists, criminals, general public,
vendors, customers and visitors. Almost anyone who has the access,
knowledge and motivation can act as an agent to take advantage of
a vulnerability.
Which agents are you concerned with? What assets might they target?
What is the probability that a specific agent will target your organization?
How much damage can the agent do?
What events are most likely to occur?
In assessing risk it is important to determine the potential events
that could result from current vulnerabilities. Examples would include:
- Misuse of authorized access (an employee divulges system passwords
to a marketing firm, or an errant email containing ePHI is sent
to a large group of unauthorized users)
- Financial fraud (think Enron, Worldcom, Healthsouth)
- Natural physical events (fires, floods)
- Unexpected systems downtime
- Unauthorized access to systems by hackers (defaced Web pages,
worms, viruses)
- Harm to employees or patients (a gang member visits a patient
to "finish the job")
- Systems are not set up to effectively monitor security incidents
- Staff does not know how to respond to security incidents
- Unauthorized access (by employees, ex-employees, the general
public) to facility areas that are not properly secured
- Ineffective disposal of ePHI and other sensitive data
What adverse events could occur at your facility? What damage or
harm could they cause? What is the likelihood of their occurring?
Have you taken steps to prevent them or minimize their impact?
What is the current control environment?
Many healthcare organizations may have some controls in place to
minimize security risks and address threats to assets. Before undertaking
new security initiatives, management should understand what is currently
being done to reduce risk within the organization. What steps have
been implemented to minimize risk? Are they adequate - and do the
meet HIPAA security standards?
What long-term factors should be considered?
While the management team's primary assessment and planning focus
will be on current and short-term risks, it should also ask what
long range organizational objectives may give rise to new risks.
Security is an ongoing process and today's potential solutions need
to be weighed against future trends as well. For example, if the
organization is considering incorporation of new technology devices
into its operations such as notebook computers, handheld devices,
and smaller storage devices such as smartcards and USB drives, executives
need to ask how existing protections - or those under consideration
- are expandable to protect tomorrow's technology. Similarly, organizations
moving into the e-health arena must plan how their web-enabled activities
will include adequate ePHI protections.
Creating a Security Program Action Plan
Once the executive team has identified and evaluated the organization's
assets, determined what agents are most likely to threaten them,
estimated the level and likelihood of harm occurring, and assessed
the adequacy of current security controls, it is time to coordinate
with appropriate IT and security staff to create a documented action
plan to reduce risk to acceptable levels. The team should examine
the HIPAA requirements to determine what gaps exist between the
current environment and the standards. These gaps represent risks
that must be addressed, although other risks may have been identified
that the organization will also want to focus on. Note that the
regulations require that security-related events or circumstances
that are certainties cannot be "managed" - and must be
addressed. An example would be that HIPAA requires unique user identification.
If your organization utilizes group user accounts, a certainty of
inadequate safeguards exists, and the security plan must include
measures to eliminate it.
Identified risks should be documented within specific areas, with
ranking such as Very High, High, Medium or Low levels of risk. This
risk ranking will assist in prioritizing activities that must be
performed. Then determine what control options exist and the cost
associated with each option. Using this information your organization
can document decisions based on reducing risk to acceptable levels,
while ensuring that resources are expended appropriately and prudently
based on the risk to the organization.
Cost is clearly one of the factors in determining what security
measures to implement. Cost is not, however, a reason for NOT implementing
security controls that are reasonable. How much is your organization
spending to ensure the security of your information and reduce risk
to an appropriate level within your organization? Is the level of
your security investment in line with the importance of ensuring
the integrity, availability and confidentiality of your ePHI?
Now, using generally accepted risk management techniques, the organization
must prioritize, budget, plan and implement controls that will limit
the risk to its assets. The Security Rule requires that you document
the actions you take to reduce risk to your assets. The old saying
applies: "If you have not documented it, you have not done
it." What documentation do you have? Is it accessible by those
who need it?
Addressing complex compliance challenges requires financial resources,
management commitment, and the appropriate staff mix and talent.
Executives should ask if their organization's HIPAA Security project
has enough financial commitment and management attention to resolve
issues before the 2005 compliance deadline. In addition, executives
must ask if they are giving the HIPAA management team appropriate
authority to facilitate the required changes in the organization.
Is staff capable of appropriately addressing the organization's
security risks? What skill sets are needed to address the challenge?
How will the project affect other organizational activities?
There is a saying that if the only tool in one's toolbox is a hammer,
all problems start to look like nails. The same adage applies to
developing and implementing a HIPAA security program. Because ePHI
may span organization boundaries, executives should ensure that
the HIPAA team represents such areas as contracts administration,
human resources, biomedical engineering, clinical departments, the
business office, and physical facilities, as well as the obvious
technical security staff.
Once the security team includes a broad spectrum of appropriate
participants, necessary individual skill sets should also be identified.
Look for a good communicator as a leader who can articulate problems
to senior management. Also look for good project management skills
to assist in the prioritization of critical tasks. Finally, staff
the team with functional experts who know internal processes and
organizational players. These individuals will be the facilitators
who will design and implement systems and process changes.
In identifying the security team, it is prudent to ask what existing
activities of participants will be affected or curtailed. Though
it is tempting to "add on" security project responsibilities
to team members' ongoing duties, supporting a major security program
wholly with part time labor may be ineffective. Job descriptions
and accountability need to be matched to ensure that enough leverage
is given to the project leaders.
Summing Up
This overview is only a starting point to help executives to examine
their HIPAA security efforts. As the project matures, it will be
necessary to incorporate changes into many of the internal processes,
work with external parties to address the risks, and change the
culture of the organization. Like many enterprise-wide initiatives,
achieving HIPAA Security compliance is a journey not a destination.
