INFORMATION TECHNOLOGY RISK ANALYSIS AND RISK MANAGEMENT OF ELECTRONIC

SCOPE
UAMS Workforce with Access
to Confidential Information, including Electronic Protected Health Information (ePHI),
for any purpose.
DEFINITIONS
Confidential Information includes information concerning UAMS research projects,
confidential employee information, information concerning the UAMS research
programs, proprietary information of UAMS, and sign-on and password codes for
access to UAMS computer systems. Confidential information shall include
Protected Health Information.
Electronic Protected Health Information means individually identifiable health
information that is:
• Transmitted by Electronic media
• Maintained in Electronic media
Information system means an interconnected set of information resources under
the same direct management control that shares common functionality. A system
normally includes hardware, software, information, data, applications,
communications, and people.
Protected Health Information (PHI) means information that is part of an
individual’s health information that identifies the individual or there is a
reasonable basis to believe the information could be used to identify the
individual, including demographic information, and that (i) relates to the past,
present or future physical or mental health or condition of the individual; (ii)
relates to the provision of health care services to the individual; or (iii)
relates to the past, present, or future payment for the provision of health care
services to an individual. This includes PHI which is recorded or transmitted in
any form or medium (verbally, or in writing, or electronically). PHI excludes
health information maintained in educational records covered by the federal
Family Educational Rights Privacy Act and health information about UAMS
employees maintained by UAMS in its role as an employer.
Risk analysis means a systematic and analytical approach that identifies and
assesses risks to the confidentiality, integrity or availability of a covered
entity’s ePHI. Risk analysis considers all relevant losses that would be
expected if specific security measures protecting ePHI are not in place.
Relevant losses include losses caused by unauthorized use and disclosure of ePHI
and loss of data integrity.

POLICY
UAMS will conduct an accurate and thorough assessment of the potential Risks and
Vulnerabilities to the confidentiality, integrity, and Availability of
Confidential Information, including Protected Health Information (PHI) and ePHI.
UAMS will take effective steps to minimize or eliminate any such potential Risks
and Vulnerabilities and will continually assess potential Risks and
Vulnerabilities by developing, implementing, and maintaining appropriate
Security Measures sufficient to reduce Risks and Vulnerabilities to a reasonable
and appropriate level. Selection and implementation of Security Measures are
based on a formal, documented Risk management process and must address the
confidentiality, integrity and Availability of UAMS Information Systems.
PROCEDURE
A. Risk Analysis: At a minimum, the UAMS Risk analysis process will be based on
the following steps:
1. Inventory of systems containing Confidential Information, including ePHI, and
Security Measures protecting such systems;
2. Threat and Vulnerability Identification and Prioritization including regular
reviews and security assessments;
3. Security Control Analysis including both preventive and detective controls;
4. Risk Likelihood Determination that assigns ratings to specific Risks that
include Threat motivation and capability, type of Vulnerability, and existence
and effectiveness of current security controls; and
5. Impact and Risk Analysis to determine the impact to confidentiality,
integrity or Availability that would result if a Threat were to successfully
exploit Vulnerabilities on UAMS systems and the adequacy of planned or existing
security controls.
In addition to regular Risk analysis, UAMS will conduct a Risk analysis when
environmental or operational changes occur which significantly impact the
confidentiality, integrity or Availability of specific Information Systems
containing Confidential Information, including ePHI. Such changes include but
are not limited to:
1. Significant Security Incidents
2. Significant new Threats or Risks
3. Significant changes to organizational or technical infrastructures
4. Significant changes to UAMS information security requirements or
responsibilities
B. Risk Management: At a minimum, the UAMS Risk management process will be based
on the following steps:
1. Inventory of UAMS systems and their Security Measures;
2. Risk Prioritization on a scale from high to low based on the potential impact
to systems containing Confidential Information, including ePHI, and the
probability of occurrence;
3. Method Selection to minimize or eliminate identified Risks to UAMS systems.
Selections must be based on the nature of a specific Risk and the feasibility
and effectiveness of a specific method;
4. Cost-benefit Analysis to identify the costs and benefits of implementing or
not implementing specific security methods for reducing Risks to systems
containing Confidential Information;
5. Assignment of Responsibility to Workforce members who have the appropriate
expertise for implementing selected security method(s); and
6. Regularly Scheduled Security Method Evaluations should be formally
documented and maintained. Security method reviews should be a
documented part of every upgrade, acquisition, and internal system
development life cycle (SDLC).
