Security Risk Assessment
By
John Beisner,
Director, University Risk Management
To further the goals set forth in the University’s
Information Security Policy (Directive 13), the University
must take reasonable steps to protect the confidentiality,
integrity and availability of its information resources. The
Office of University Risk Management is developing tools academic
departments and administrative units can use to conduct a
risk assessment that will:
1.
|
Identify and assess
information protected by federal and state laws and regulations,
and University policies; |
2. |
Identify and assess the vulnerability
of this information; and |
3. |
Implement appropriate risk control
measures. |
University Risk Management will begin working with departments
and units to conduct this risk assessment in the second half
of 2005.
Identification and Assessment of Information
Assets
The first step in the risk assessment
process involves identifying the protected information collected,
used, and maintained by the University, the amount of this
information, how this information is stored (both electronically
and in hard copy), the security measures in place, who has
access to this information, and other departments or units
that use or rely on this information. During the past two
months, divisional information technology coordinators and
departmental technicians have completed much of this work.
Each department or unit will also assess
on a scale of high-medium-low the information’s confidentiality
(What would the impact be if the information was compromised?
or How regulated is the information?), integrity
(How important is the accuracy/reliability of the information?)
and availability (How much of the department’s
ability to function depends on access to the information?).
While determining integrity and availability is department-specific,
social security numbers, driver’s license numbers, state
identification numbers, grades or documents related to academic
performance, personal financial information such as bank account,
insurance and credit card numbers, performance evaluations
or documents related to employee performance, income and credit
histories, home addresses and telephone numbers, and medical
information in every instance rank “high” on the
confidentiality scale. This list is not exhaustive.
Identification and Assessment of Risks
The second step in the risk assessment process requires departments
to identify the threats to the electronic and hard copy information
they use. Threats may be deliberate, such
as theft and mischief, or accidental, such
as power outages, hardware failure or natural disasters. Threats
can result in destruction, disclosure, removal, corruption
of information or interruption of University operations. In
addition to often cited threats such as theft, computer viruses,
fire and hacking attempts, less obvious risks include unmanaged
software installation, unavailability of key staff, attempts
by untrained staff to correct a problem, reliance on outdated
on non-replaceable equipment, and loss of facilities.
After identifying threats, departments will then assess on
a scale of high-medium-low the probability
that a threat will occur. Departments might find the following
questions helpful when reviewing vulnerability:
- The greater the number of individuals
with access, the more vulnerable the information.
- The greater the public’s access
to the location where the information is used or stored,
the more likely a threat will occur.
- The more places and ways the information
is stored, the greater the vulnerability.
- The greater the amount of information
stored, the greater the vulnerability.
- The more “interesting”
the information, the greater the vulnerability.
- The more ways to access the information,
the more likely a threat will occur.
- The more potential threats, the
greater the vulnerability.
Implementation of Appropriate
Risk Control Measures
Once the protected information and threats have been identified
and assessed, the department or unit can then prioritize its
information security efforts and determine the appropriate
level of protection. The University will provide guidance
regarding what physical, systems and administrative safeguards
are required based on the level of confidentiality, integrity,
availability and vulnerability. Departments and units will
then be responsible for implementing the appropriate recommendations,
or changing how they collect, use or maintain information.
