Unit Lesson
Introduction
The previous unit briefly introduced you to risk strategies and risk management applicable to most common
events in our society. We covered the potential sources of risks and the difference between internal and
external risks; however, many critical infrastructure sectors have unique sources of risks requiring specific
methodologies for risk assessment.
Proper risk assessment methodologies are indispensable for critical sectors in order to identify threats,
assess vulnerabilities, and calculate the impact to systems or assets within those critical infrastructures.
Furthermore, consideration must be as to the probability of occurrence of those events to specific sectors.
Complexities do exist because the scope of these risks assessments is broader and must deal with research
institutes, nationwide decision-making, and policy-making at the highest governmental levels. In other words,
there is a significant differentiation between risk assessment methodologies based on the scope of the
sectors, the audience, and the stakeholders involved in those decisions.
The other important aspect of critical infrastructure, risk assessment methodologies, is that of networked
infrastructures and the interdependencies between the different sectors. Rinaldi, et al. (2001) identified four
types of critical infrastructure interdependencies.
1. Physical interdependencies are those in which one infrastructure depends on another for its input
(e.g., the electrical grid in some aspects depends on the water system, for example, where dams are
used to generate electricity).
2. Cyber dependencies are those in which most critical infrastructure sectors depend on the information
provided by the information systems infrastructure (many sectors such as the electrical grid use the
Internet to report metrics or control substations remotely).
3. Geographic dependencies are those in which environmental events affect other critical infrastructures
(the presence of hurricanes endangers other infrastructures such as the energy, waterways, and
transportation sectors).
4. Logical dependencies may be any dependency not characterized by physical, cyber, or geographic
(These can be social, economic, political, and legal forces affecting one or multiple sectors. An
example includes the economic collapse of an area affecting the maintenance of a critical sector such
as waterways that could result in the deterioration of the water-retaining structures in dams,
potentially causing a flood).

Title
Homeland Security
Homeland security has been a critical topic at all levels of society in many countries. This is reflected in the
different agencies tasked with the overall security of many nations. Homeland security refers to protecting and
safeguarding a country’s internal environment from disruptive events or activities leading to critical
disruptions, loss of lives, and destruction of public and/or private property. In the United States, specifically,
the Department of Homeland Security (DHS) is the agency tasked with the oversight and coordination of the
country’s critical infrastructure sectors. This is a daunting endeavor because the private sector owns and
protects roughly 85 percent of the nation’s infrastructure (Government Accountability Office, 2006).
The charter established in Homeland Security Presidential Directive 7 (HSPD-7) outlines the details and
processes for CIKR safeguards (HSPD-7, 2003). HSPD-7 directives are a set of federal policies to enhance
protection for the nation’s critical infrastructure sectors and specifically mandates a strategic plan that follows
such policies. In this directive, the president appointed a secretary of homeland security as the “principal
federal official to lead CIKR protection efforts among federal departments and agencies, state and local
governments, and the private sector” (p. 12).
Critical Infrastructure Key Resources (CIKRs)
CIKRs are of strategic importance for the nation as they encompass trade, economic, technological, and
political interests. As noted in previous units, CIKRs include physical assets such as buildings and
infrastructures as well as transportation and communication networks. According to the President’s National
Strategy for Homeland Security, “Government at the federal, state, and local level must actively collaborate
and partner with the private sector, which controls 85 percent of America’s infrastructure . . . the nation’s
infrastructure protection effort must harness the capabilities of the private sector to achieve a prudent level of
security without hindering productivity, trade, or economic growth” (Department of Justice, Bureau of Justice
Assistance, 2005, p. viii).
In Unit I, we expanded the number of critical sectors to 18. Homeland security in the United States is the task
of many agencies, public and private. The number of CIKRs makes the protection of all these different sectors
complex as it requires the coordination of the public and private sectors. Protection of CIKR assets from
physical and cyberthreats requires communication, cooperation, coordination, and collaboration as these
elements are critical between the public and private sectors. The Department of Homeland Security initiated
and supports the Control System Security Program (CSSP) in order to reduce risks to the nation’s critical
infrastructure sectors through partnerships with public and private sectors (McGurk, 2009). Furthermore,
National Risk Assessments must be conducted frequently to identify and prepare for potential new
vulnerabilities and threats specifically when it comes to cybersecurity in public and private sectors.

Title
Threats and Vulnerabilities Protection
The protection of CIKRs requires specific focus on not only physical infrastructures but on communication
networks unique to the telecommunication, financial, and energy sectors. All CIKRs must constantly evaluate
the risks and vulnerabilities to the assets from any threats along with the development of unique
countermeasures and emergency contingency plans to preempt any attacks to the critical infrastructure.
Although the protection of CIKRs is perceived as the sole responsibility of the federal government, it is also
the responsibility of private sectors, thus, as already noted the need for public-private partnership is
paramount.

Title
Case Study
Our textbook covers different theories on catastrophe. An additional example follows on how we can apply
some of these theories to events that most of us have experienced.
Financial Meltdown of 2008
We can apply Bak’s theory of self-organized criticality (SOC) to the financial meltdown of 2008. The theory
posits that the criticality (meltdown) was caused by previous events. When the United States prevented the
financial system from collapsing in 1997, it triggered the collapse of the tech market in 2001-02. Similarly, the
actions of the federal government in preventing the tech market collapse in 2001-02 triggered the housing
bubble, which burst in 2007-09. Thus, in essence, the process by which many complex systems go from
stable to unstable is called self-organized criticality or SOC. Steps that are taken to prevent the system from
collapsing create a feedback loop that causes the system to eventually collapse.
Observations
• Percolation increases SOC.
• Risks increase with SOC.
• Paradox of enrichment (too much of a good thing?)
o When exceeding the carrying capacity of an ecological system, you risk its collapse.
• Sand pile effect (complex systems cause cascading and landslides)
As it pertains to CIKRs, actions/events can cause triggers for disasters. As an example:
• increasing the capacity of a network could reduce overall performance;
• spreading more pesticides could increase the pest population; and
• increasing the number of security personnel could amplify breaches.
Summary
As the world becomes more connected, threats and vulnerabilities increase to the nation’s CIKRs. The
country’s state of homeland security continues to go through reforms in order to adapt to the ever-changing
physical threats and cyberthreats. In order to keep up with the shifting landscape, the government must forge
strategic partnerships with other countries and with private sectors to strengthen homeland security
strategies.
Definitions
Below are some definitions introduced in the unit lesson that you should take some time to review.
• Percolation increases risk by increasing the juxtaposition and structure (spectral radius) of a CIKR
system represented as a network.
CORE CONCEPTS

Unit Lesson
Introduction
The previous unit briefly introduced you to risk strategies and risk management applicable to most common
events in our society. We covered the potential sources of risks and the difference between internal and
external risks; however, many critical infrastructure sectors have unique sources of risks requiring specific
methodologies for risk assessment.
Proper risk assessment methodologies are indispensable for critical sectors in order to identify threats,
assess vulnerabilities, and calculate the impact to systems or assets within those critical infrastructures.
Furthermore, consideration must be as to the probability of occurrence of those events to specific sectors.
Complexities do exist because the scope of these risks assessments is broader and must deal with research
institutes, nationwide decision-making, and policy-making at the highest governmental levels. In other words,
there is a significant differentiation between risk assessment methodologies based on the scope of the
sectors, the audience, and the stakeholders involved in those decisions.
The other important aspect of critical infrastructure, risk assessment methodologies, is that of networked
infrastructures and the interdependencies between the different sectors. Rinaldi, et al. (2001) identified four
types of critical infrastructure interdependencies.
1. Physical interdependencies are those in which one infrastructure depends on another for its input
(e.g., the electrical grid in some aspects depends on the water system, for example, where dams are
used to generate electricity).
2. Cyber dependencies are those in which most critical infrastructure sectors depend on the information
provided by the information systems infrastructure (many sectors such as the electrical grid use the
Internet to report metrics or control substations remotely).
3. Geographic dependencies are those in which environmental events affect other critical infrastructures
(the presence of hurricanes endangers other infrastructures such as the energy, waterways, and
transportation sectors).
4. Logical dependencies may be any dependency not characterized by physical, cyber, or geographic
(These can be social, economic, political, and legal forces affecting one or multiple sectors. An
example includes the economic collapse of an area affecting the maintenance of a critical sector such
as waterways that could result in the deterioration of the water-retaining structures in dams,
potentially causing a flood).

Title
Homeland Security
Homeland security has been a critical topic at all levels of society in many countries. This is reflected in the
different agencies tasked with the overall security of many nations. Homeland security refers to protecting and
safeguarding a country’s internal environment from disruptive events or activities leading to critical
disruptions, loss of lives, and destruction of public and/or private property. In the United States, specifically,
the Department of Homeland Security (DHS) is the agency tasked with the oversight and coordination of the
country’s critical infrastructure sectors. This is a daunting endeavor because the private sector owns and
protects roughly 85 percent of the nation’s infrastructure (Government Accountability Office, 2006).
The charter established in Homeland Security Presidential Directive 7 (HSPD-7) outlines the details and
processes for CIKR safeguards (HSPD-7, 2003). HSPD-7 directives are a set of federal policies to enhance
protection for the nation’s critical infrastructure sectors and specifically mandates a strategic plan that follows
such policies. In this directive, the president appointed a secretary of homeland security as the “principal
federal official to lead CIKR protection efforts among federal departments and agencies, state and local
governments, and the private sector” (p. 12).
Critical Infrastructure Key Resources (CIKRs)
CIKRs are of strategic importance for the nation as they encompass trade, economic, technological, and
political interests. As noted in previous units, CIKRs include physical assets such as buildings and
infrastructures as well as transportation and communication networks. According to the President’s National
Strategy for Homeland Security, “Government at the federal, state, and local level must actively collaborate
and partner with the private sector, which controls 85 percent of America’s infrastructure . . . the nation’s
infrastructure protection effort must harness the capabilities of the private sector to achieve a prudent level of
security without hindering productivity, trade, or economic growth” (Department of Justice, Bureau of Justice
Assistance, 2005, p. viii).
In Unit I, we expanded the number of critical sectors to 18. Homeland security in the United States is the task
of many agencies, public and private. The number of CIKRs makes the protection of all these different sectors
complex as it requires the coordination of the public and private sectors. Protection of CIKR assets from
physical and cyberthreats requires communication, cooperation, coordination, and collaboration as these
elements are critical between the public and private sectors. The Department of Homeland Security initiated
and supports the Control System Security Program (CSSP) in order to reduce risks to the nation’s critical
infrastructure sectors through partnerships with public and private sectors (McGurk, 2009). Furthermore,
National Risk Assessments must be conducted frequently to identify and prepare for potential new
vulnerabilities and threats specifically when it comes to cybersecurity in public and private sectors.

Title
Threats and Vulnerabilities Protection
The protection of CIKRs requires specific focus on not only physical infrastructures but on communication
networks unique to the telecommunication, financial, and energy sectors. All CIKRs must constantly evaluate
the risks and vulnerabilities to the assets from any threats along with the development of unique
countermeasures and emergency contingency plans to preempt any attacks to the critical infrastructure.
Although the protection of CIKRs is perceived as the sole responsibility of the federal government, it is also
the responsibility of private sectors, thus, as already noted the need for public-private partnership is
paramount.

Title
Case Study
Our textbook covers different theories on catastrophe. An additional example follows on how we can apply
some of these theories to events that most of us have experienced.
Financial Meltdown of 2008
We can apply Bak’s theory of self-organized criticality (SOC) to the financial meltdown of 2008. The theory
posits that the criticality (meltdown) was caused by previous events. When the United States prevented the
financial system from collapsing in 1997, it triggered the collapse of the tech market in 2001-02. Similarly, the
actions of the federal government in preventing the tech market collapse in 2001-02 triggered the housing
bubble, which burst in 2007-09. Thus, in essence, the process by which many complex systems go from
stable to unstable is called self-organized criticality or SOC. Steps that are taken to prevent the system from
collapsing create a feedback loop that causes the system to eventually collapse.
Observations
• Percolation increases SOC.
• Risks increase with SOC.
• Paradox of enrichment (too much of a good thing?)
o When exceeding the carrying capacity of an ecological system, you risk its collapse.
• Sand pile effect (complex systems cause cascading and landslides)
As it pertains to CIKRs, actions/events can cause triggers for disasters. As an example:
• increasing the capacity of a network could reduce overall performance;
• spreading more pesticides could increase the pest population; and
• increasing the number of security personnel could amplify breaches.
Summary
As the world becomes more connected, threats and vulnerabilities increase to the nation’s CIKRs. The
country’s state of homeland security continues to go through reforms in order to adapt to the ever-changing
physical threats and cyberthreats. In order to keep up with the shifting landscape, the government must forge
strategic partnerships with other countries and with private sectors to strengthen homeland security
strategies.
Definitions
Below are some definitions introduced in the unit lesson that you should take some time to review.
• Percolation increases risk by increasing the juxtaposition and structure (spectral radius) of a CIKR
system represented as a network.
CORE CONCEPTS
Directives of Homeland Security
Responsibility and Accountability
– Assign lead agencies for homeland security initiatives
Mobilization of Society
– Be cognizant of the critical role state and local agencies, private institutions, and
society play in securing the homeland.
– Recognize that because of the complexity of protecting critical sectors, organizations
outside of the government may take the lead in many of the protection efforts
(HSPD-7, 2003).

Title
• Resilience is the ability to resist, absorb, recover from or successfully adapt to adversity or a change
in conditions.
• Self-organized criticality is measured in terms of spectral radius, which is a measure of network
structure and equates to fragility and nonresilience.

The previous unit briefly introduced you to risk strategies and risk management applicable to most common
events in our society. We covered the potential sources of risks and the difference between internal and
external risks; however, many critical infrastructure sectors have unique sources of risks requiring specific
methodologies for risk assessment.
Proper risk assessment methodologies are indispensable for critical sectors in order to identify threats,
assess vulnerabilities, and calculate the impact to systems or assets within those critical infrastructures.
Furthermore, consideration must be as to the probability of occurrence of those events to specific sectors.
Complexities do exist because the scope of these risks assessments is broader and must deal with research

The other important aspect of critical infrastructure, risk assessment methodologies, is that of networked
infrastructures and the interdependencies between the different sectors. Rinaldi, et al. (2001) identified four
types of critical infrastructure interdependencies.
1. Physical interdependencies are those in which one infrastructure depends on another for its input

used to generate electricity).
2. Cyber dependencies are those in which most critical infrastructure sectors depend on the information

example includes the economic collapse of an area affecting the maintenance of a critical sector such
as waterways that could result in the deterioration of the water-retaining structures in dams,

Homeland Security
Homeland security has been a critical topic at all levels of society in many countries. This is reflected in the
different agencies tasked with the overall security of many nations. Homeland security refers to protecting and
safeguarding a country’s internal environment from disruptive events or activities leading to critical
disruptions, loss of lives, and destruction of public and/or private property. In the United States, specifically,
the Department of Homeland Security (DHS) is the agency tasked with the oversight and coordination of the
country’s critical infrastructure sectors. This is a daunting endeavor because the private sector owns and
protects roughly 85 percent of the nation’s infrastructure (Government Accountability Office, 2006).
The charter established in Homeland Security Presidential Directive 7 (HSPD-7) outlines the details and
processes for CIKR safeguards (HSPD-7, 2003). HSPD-7 directives are a set of federal policies to enhance
protection for the nation’s critical infrastructure sectors and specifically mandates a strategic plan that follows
such policies. In this directive, the president appointed a secretary of homeland security as the “principal
federal official to lead CIKR protection efforts among federal departments and agencies, state and local
governments, and the private sector” (p. 12).
Critical Infrastructure Key Resources (CIKRs)
CIKRs are of strategic importance for the nation as they encompass trade, economic, technological, and
political interests. As noted in previous units, CIKRs include physical assets such as buildings and
infrastructures as well as transportation and communication networks. According to the President’s National
Strategy for Homeland Security, “Government at the federal, state, and local level must actively collaborate
and partner with the private sector, which controls 85 percent of America’s infrastructure . . . the nation’s
infrastructure protection effort must harness the capabilities of the private sector to achieve a prudent level of
security without hindering productivity, trade, or economic growth” (Department of Justice, Bureau of Justice
Assistance, 2005, p. viii).
In Unit I, we expanded the number of critical sectors to 18. Homeland security in the United States is the task
of many agencies, public and private. The number of CIKRs makes the protection of all these different sectors
complex as it requires the coordination of the public and private sectors. Protection of CIKR assets from
physical and cyberthreats requires communication, cooperation, coordination, and collaboration as these
elements are critical between the public and private sectors. The Department of Homeland Security initiated
and supports the Control System Security Program (CSSP) in order to reduce risks to the nation’s critical
infrastructure sectors through partnerships with public and private sectors (McGurk, 2009). Furthermore,
National Risk Assessments must be conducted frequently to identify and prepare for potential new
vulnerabilities and threats specifically when it comes to cybersecurity in public and private sectors.

Title
Threats and Vulnerabilities Protection
The protection of CIKRs requires specific focus on not only physical infrastructures but on communication
networks unique to the telecommunication, financial, and energy sectors. All CIKRs must constantly evaluate
the risks and vulnerabilities to the assets from any threats along with the development of unique
countermeasures and emergency contingency plans to preempt any attacks to the critical infrastructure.
Although the protection of CIKRs is perceived as the sole responsibility of the federal government, it is also
the responsibility of private sectors, thus, as already noted the need for public-private partnership is
paramount.

Title
Case Study
Our textbook covers different theories on catastrophe. An additional example follows on how we can apply
some of these theories to events that most of us have experienced.
Financial Meltdown of 2008
We can apply Bak’s theory of self-organized criticality (SOC) to the financial meltdown of 2008. The theory
posits that the criticality (meltdown) was caused by previous events. When the United States prevented the
financial system from collapsing in 1997, it triggered the collapse of the tech market in 2001-02. Similarly, the
actions of the federal government in preventing the tech market collapse in 2001-02 triggered the housing
bubble, which burst in 2007-09. Thus, in essence, the process by which many complex systems go from
stable to unstable is called self-organized criticality or SOC. Steps that are taken to prevent the system from
collapsing create a feedback loop that causes the system to eventually collapse.
Observations
• Percolation increases SOC.
• Risks increase with SOC.
• Paradox of enrichment (too much of a good thing?)
o When exceeding the carrying capacity of an ecological system, you risk its collapse.
• Sand pile effect (complex systems cause cascading and landslides)
As it pertains to CIKRs, actions/events can cause triggers for disasters. As an example:
• increasing the capacity of a network could reduce overall performance;
• spreading more pesticides could increase the pest population; and
• increasing the number of security personnel could amplify breaches.
Summary
As the world becomes more connected, threats and vulnerabilities increase to the nation’s CIKRs. The
country’s state of homeland security continues to go through reforms in order to adapt to the ever-changing
physical threats and cyberthreats. In order to keep up with the shifting landscape, the government must forge
strategic partnerships with other countries and with private sectors to strengthen homeland security
strategies.
Definitions
Below are some definitions introduced in the unit lesson that you should take some time to review.
• Percolation increases risk by increasing the juxtaposition and structure (spectral radius) of a CIKR
system represented as a network.
CORE CONCEPTS
Directives of Homeland Security
Responsibility and Accountability
– Assign lead agencies for homeland security initiatives
Mobilization of Society
– Be cognizant of the critical role state and local agencies, private institutions, and
society play in securing the homeland.
– Recognize that because of the complexity of protecting critical sectors, organizations
outside of the government may take the lead in many of the protection efforts
(HSPD-7, 2003).

Title
• Resilience is the ability to resist, absorb, recover from or successfully adapt to adversity or a change
in conditions.
• Self-organized criticality is measured in terms of spectral radius, which is a measure of network
structure and equates to fragility and nonresilience.
