Policy Writing Approach
Refer to “Case Study: Policy Writing Approach” found on page 102 of your textbook and copied below.
Regional Bank has been growing rapidly. In the past two years, it has acquired six smaller financial institutions. The long-term strategic plan is for the bank to keep growing and to “go public” within the next three to five years. FDIC regulators have told management that they will not approve any additional acquisitions until the bank strengthens its information security program. The regulators commented that Regional Bank’s information security policy is confusing, lacking in structure, and filled with discrepancies.
You have been tasked with fixing the problems with the policy document. Write a two-page case study that includes the following sections.
· Introduction: Current Problem
· Discussion
· Where do you begin this project?
· Would you use any material from the original document?

Chapter 3: Cybersecurity Framework
Unit Lesson
In the previous unit, we covered the policy hierarchy, including the standards, guidelines, procedures, and
baselines. We now focus on the security framework to include confidentiality, integrity, and availability (CIA),
and security models. The framework should address the organization’s overall purpose for creating its
policies. It is necessary to have a common security strategy or model because this helps dictate how all
policies are created. If we understand the importance of CIA, then it helps us define how the documents, data,
Internet, email, and systems should be treated. We can also see how adopting a model can help establish IT
governance, which usually drives the creation of the policies. If no model is adopted by the organization, then
it makes it more difficult for organizations to provide justification for the policies and procedures.

Title
Confidentiality
Organizations want a majority of their internal
information to be protected and not shared
externally. Santos (2019) explains
confidentiality as the requirement that
employees not disclose private and confidential
information to unauthorized individuals.
Consider all of the documents, emails, and
procedures that organizations have on shared
drives, email folders, and removable media.
What happens if any of these storage locations
are breached? This is why organizations
provide multiple authentications and access
controls to protect their data and information.
Many small- and medium-size businesses do
not create policies to address how information
should be protected. Therefore, these
organizations are at risk when it comes to their
data and information. Santos (2019) illustrates
how organizations can also use encryption of
data, virtual private networks (VPNs), and
server/client encryption using transport layer
security (TLS). It is key to note some of the
common concerns are related to unethical
employees misusing the information or
intentionally distributing the information to
unauthorized personnel.
Integrity
The integrity of a system or infrastructure is critical because it can ultimately determine overall protection of
the data and information. There are thousands of Web applications online connecting to Microsoft SQL
Server, MySQL, or Oracle databases. Think about a website that is connecting to a MySQL database. If this
website login is penetrated, then a hacker can do almost anything to the data, including manipulations or
deletions. These database interfaces are well designed, but access controls and logins can be insufficient
from a Web application. This becomes a major issue if a hacker can gain access to the Web application and
then connect to the database. The integrity of the system is the ability to ensure the system and its data have
not been altered or compromised. How long do you think it would take for a database administrator (DBA) to
find out that an unauthorized individual has accessed the data? If it is a small company, then it could take a
while. The key here is to consider what policies should be in place to address the integrity of a system,
application, or data.
The figure below shows how Integrity needs to apply to both the data and systems. As we know, the system
or applications retain the data, so focusing on the integrity protections for both is imperative.

Availability
Availability refers to the continuous access of the data, systems, and applications. What happens if your
organization experiences a denial of service (DOS) attack? If the attack brings down the network, then the
systems and data are no longer available. As we have seen throughout the years, organizations lose millions
of dollars when their websites or portals are not available to the customers and clients.
The following site provides insights on the latest cyber and digital hijacking events. The benefit of checking a

difficult to read all current posts, but visiting the site regularly will provides insights on current issues and
provide inspiration for new policies or revisions to existing policies.
DDOS Attacks website: http://ddosattacks.net/latest-news/
The article below explains attacks by Trojan horses, botnets, and distributed denial of service (DDOS). These
attacks are alarming because they are not only destructive, but also cause loss of availability with the
networks and systems. It is explained in the article is that most attacks are associated with financial gains by
the criminals or competition to gain more sensitive information. We can consider competitors not only
competing firms; they can also be other countries.

Models
Security architectures involve the study of formal security models at the highest levels of IT security such as
those that protect our national security and other governmental agencies. Below, we will review the National
Institute of Standards and Technology (NIST) Framework and Internal Organization for Standards (ISO) to
determine how these entities help form the policies. These standards are essential, especially for small and
medium-size businesses, because they act as guidelines and templates for IT personnel to use within their
organization. As mentioned by Santos (2019), although developed for government use, the framework is
applicable to the private sector, and it addresses the management, operational, and technical aspects of
protecting the CIA.
NIST Framework
The NIST’s mission is to raise awareness of IT risks, provide cost-effective solutions, deploy security
standards, and provide security guidance for IT planning, implementations, and management (Santos, 2019).
NIST provides a quick search option, which can be found here, to locate the necessary documentation or
templates that can be used for standard processes. Many of the templates are living documents;
consequently, they are updated as needed to address new concerns or provide alternative approaches. In
regard to IS security, NIST defines it as the protection of information and information systems from
unauthorized access, use, disclosure, disruption, modification, or destruction (NIST, 2018).
ISO Standards
The International Organization for Standardization (ISO) provides requirements, specifications, and guidelines
that organizations can use. The standards provide frameworks for organizations to create security policies,
identify roles to protect the organization, offer employment check practices for hiring new employees, manage
assets, and control access to systems, networks, and facilities. These standards help organizations create
and maintain security policies using best practices identified in the industries. It is important to note these
guides can be altered to meet each business environment. Additionally, the organization may have future
audits so building policies that align with ISO standards justifies the content provided for the policies along
with the reason for access control parameters. These recommendations can be applied to many domains
associated with organization, human resources, access control, asset management, cryptography,
operations, communication, and business continuity. An excellent place to start is by going to the ISO.org
website and examining specific standards.

Summary
In summary, we covered the CIA model, NIST, and ISO standards, which help build an organization
cybersecurity framework. As mentioned, organizations can use these models and standards as
recommendations to help develop a secure and solid framework. Organizations have to review these
practices routinely in order to keep the policies current with the industry. Luckily, these recommendations do
not change too often, but we know cyberattacks are constantly evolving; consequently, organizations can use
these as baselines and augment them with current prevention techniques.

cybersecurity framework. As mentioned, organizations can use these models and standards as
recommendations to help develop a secure and solid framework. Organizations have to review these
practices routinely in order to keep the policies current with the industry. Luckily, these recommendations do
not change too often, but we know cyberattacks are constantly evolving; consequently, organizations can use
these as baselines and augment them with current prevention techniques.

Policy Writing Approach
Refer to “Case Study: Policy Writing Approach” found on page 102 of your textbook and copied below.
Regional Bank has been growing rapidly. In the past two years, it has acquired six smaller financial institutions. The long-term strategic plan is for the bank to keep growing and to “go public” within the next three to five years. FDIC regulators have told management that they will not approve any additional acquisitions until the bank strengthens its information security program. The regulators commented that Regional Bank’s information security policy is confusing, lacking in structure, and filled with discrepancies.
You have been tasked with fixing the problems with the policy document. Write a two-page case study that includes the following sections.
· Introduction: Current Problem
· Discussion
· Where do you begin this project?
· Would you use any material from the original document?
· What other materials should you request?
· Would you want to interview the author of the original policy?
· Who else would you interview? Should the bank work toward ISO certification?
· Which ISO 27002:2022 domains and sections would you include?
· Should you use NIST’s Cybersecurity Framework (CIA security model) and related tools? If yes, explain why the tools selected are important to IS policy writing.
· Which methods of communication should you use to send the policy?
· What other criteria should you consider?
· Conclusion
· References
Your paper should include a title page and a reference page, which do not count toward the two-page minimum. Use APA

Chapter 3: Cybersecurity Framework
Unit Lesson
In the previous unit, we covered the policy hierarchy, including the standards, guidelines, procedures, and
baselines. We now focus on the security framework to include confidentiality, integrity, and availability (CIA),
and security models. The framework should address the organization’s overall purpose for creating its
policies. It is necessary to have a common security strategy or model because this helps dictate how all
policies are created. If we understand the importance of CIA, then it helps us define how the documents, data,
Internet, email, and systems should be treated. We can also see how adopting a model can help establish IT
governance, which usually drives the creation of the policies. If no model is adopted by the organization, then
it makes it more difficult for organizations to provide justification for the policies and procedures.

Title
Confidentiality
Organizations want a majority of their internal
information to be protected and not shared
externally. Santos (2019) explains
confidentiality as the requirement that
employees not disclose private and confidential
information to unauthorized individuals.
Consider all of the documents, emails, and
procedures that organizations have on shared
drives, email folders, and removable media.
What happens if any of these storage locations
are breached? This is why organizations
provide multiple authentications and access
controls to protect their data and information.
Many small- and medium-size businesses do
not create policies to address how information
should be protected. Therefore, these
organizations are at risk when it comes to their
data and information. Santos (2019) illustrates
how organizations can also use encryption of
data, virtual private networks (VPNs), and
server/client encryption using transport layer
security (TLS). It is key to note some of the
common concerns are related to unethical
employees misusing the information or
intentionally distributing the information to
unauthorized personnel.
Integrity
The integrity of a system or infrastructure is critical because it can ultimately determine overall protection of
the data and information. There are thousands of Web applications online connecting to Microsoft SQL
Server, MySQL, or Oracle databases. Think about a website that is connecting to a MySQL database. If this
website login is penetrated, then a hacker can do almost anything to the data, including manipulations or
deletions. These database interfaces are well designed, but access controls and logins can be insufficient
from a Web application. This becomes a major issue if a hacker can gain access to the Web application and
then connect to the database. The integrity of the system is the ability to ensure the system and its data have
not been altered or compromised. How long do you think it would take for a database administrator (DBA) to
find out that an unauthorized individual has accessed the data? If it is a small company, then it could take a
while. The key here is to consider what policies should be in place to address the integrity of a system,
application, or data.
The figure below shows how Integrity needs to apply to both the data and systems. As we know, the system
or applications retain the data, so focusing on the integrity protections for both is imperative.
Integrity is connected to both the data and system

Availability
Availability refers to the continuous access of the data, systems, and applications. What happens if your
organization experiences a denial of service (DOS) attack? If the attack brings down the network, then the
systems and data are no longer available. As we have seen throughout the years, organizations lose millions
of dollars when their websites or portals are not available to the customers and clients.
The following site provides insights on the latest cyber and digital hijacking events. The benefit of checking a
site like this is to review the latest practices or review the unfortunate events for other organizations. It can be
difficult to read all current posts, but visiting the site regularly will provides insights on current issues and
provide inspiration for new policies or revisions to existing policies.
DDOS Attacks website: http://ddosattacks.net/latest-news/
The article below explains attacks by Trojan horses, botnets, and distributed denial of service (DDOS). These
attacks are alarming because they are not only destructive, but also cause loss of availability with the
networks and systems. It is explained in the article is that most attacks are associated with financial gains by
the criminals or competition to gain more sensitive information. We can consider competitors not only
competing firms; they can also be other countries.

Models
Security architectures involve the study of formal security models at the highest levels of IT security such as
those that protect our national security and other governmental agencies. Below, we will review the National
Institute of Standards and Technology (NIST) Framework and Internal Organization for Standards (ISO) to
determine how these entities help form the policies. These standards are essential, especially for small and
medium-size businesses, because they act as guidelines and templates for IT personnel to use within their
organization. As mentioned by Santos (2019), although developed for government use, the framework is
applicable to the private sector, and it addresses the management, operational, and technical aspects of
protecting the CIA.
NIST Framework
The NIST’s mission is to raise awareness of IT risks, provide cost-effective solutions, deploy security
standards, and provide security guidance for IT planning, implementations, and management (Santos, 2019).
NIST provides a quick search option, which can be found here, to locate the necessary documentation or
templates that can be used for standard processes. Many of the templates are living documents;
consequently, they are updated as needed to address new concerns or provide alternative approaches. In
regard to IS security, NIST defines it as the protection of information and information systems from
unauthorized access, use, disclosure, disruption, modification, or destruction (NIST, 2018).
ISO Standards
The International Organization for Standardization (ISO) provides requirements, specifications, and guidelines
that organizations can use. The standards provide frameworks for organizations to create security policies,
identify roles to protect the organization, offer employment check practices for hiring new employees, manage
assets, and control access to systems, networks, and facilities. These standards help organizations create
and maintain security policies using best practices identified in the industries. It is important to note these
guides can be altered to meet each business environment. Additionally, the organization may have future
audits so building policies that align with ISO standards justifies the content provided for the policies along
with the reason for access control parameters. These recommendations can be applied to many domains
associated with organization, human resources, access control, asset management, cryptography,
operations, communication, and business continuity. An excellent place to start is by going to the ISO.org
website and examining specific standards.
