To begin this project, you will take the role of a cybersecurity consultant tasked with implementing an ISMS for a public organization. Your goal is to develop a basic ISMS to ensure that the organization can properly manage and secure its information. This project will guide you through defining the scope, conducting a risk assessment, selecting controls, and documenting security policies and procedures. Use the provided instructions and checklists to organize your work.
To develop a foundational ISMS for a public organization scenario, ensuring the organization has a formal structure for information security management that identifies risks, selects appropriate controls, and maintains effective security policies and procedures.
Choose one of the following types of public organizations for your ISMS project:
When selecting your organization, consider the following criteria:
To develop an Information Security Management System (ISMS) for a public organization, it’s crucial to choose an organization that has a substantial amount of publicly accessible information. Here are some types of organizations along with recommendations and links to information sources that would facilitate the ISMS project:
| Organization | Description | Information Sources |
|---|---|---|
| United States Postal Service (USPS) | Complex public service organization handling sensitive citizen information. Ideal for ISMS. | USPS Reports and Publications |
| National Institute of Standards and Technology (NIST) | Provides numerous resources for public transparency, including risk assessment guidelines and policies. | NIST Public Information |
| University of California System | Public university system with accessible documents on cybersecurity standards, privacy policies, and risk management. | University of California Information Security Office |
| New York City Health + Hospitals | Manages extensive patient data with available annual reports, financial reports, and IT security strategies. | NYC Health + Hospitals Publications |
| National Health Service (NHS), UK | Extensive information about privacy policies, cybersecurity strategies, and public health data management. | NHS Digital – Data and Information Governance |
| Metropolitan Transportation Authority (MTA), New York | Publishes extensive documentation on operational plans, cybersecurity policies, and financial statements. | MTA Financial and Budget Reports |
| Transport for London (TfL) | Provides transparency reports, risk management documentation, and compliance policies related to information technology. | Safety & Security |
| World Health Organization (WHO) | Publicly available documents related to privacy and cybersecurity policies, along with annual reports on IT infrastructure. | WHO Publications |
| UNICEF | Publishes annual reports, financial statements, and cybersecurity and privacy policies. | UNICEF Reports and Data |
These organizations have extensive information on their public websites, which will help you to gather data needed for the ISMS, conduct a risk assessment, select controls, and create appropriate policies and procedures. Let me know if you need additional details or further guidance on specific steps of the ISMS project.
Define the scope of the ISMS to establish the boundaries of what needs to be secured.
Create an inventory of all information assets, such as computers, servers, databases, citizen/student/patient information, research data, etc.
Identify and classify assets based on their importance to operations (e.g., critical, high, medium, low).
Determine which physical locations are included in the ISMS (e.g., offices, data centers, campuses).
Identify areas that need restricted access (e.g., server rooms, research laboratories).
Identify networks, cloud environments, and virtual machines that are included in the ISMS.
Specify which systems and data types fall under ISMS control.
Identify key stakeholders (e.g., IT team, management, employees, citizens/students/patients).
Assign responsibilities to each stakeholder for information security activities.
Document the purpose of the ISMS, including its scope, goals, and objectives.
Specify any limitations or exclusions.
Identify and assess the risks associated with the organization and its assets.
Develop a comprehensive list of all assets identified in the scope definition.
Classify assets into categories such as hardware, software, data, and personnel.
Identify possible threats that may affect each asset (e.g., unauthorized access, malware, natural disasters, data breaches).
Consider both external and internal threats.
Identify vulnerabilities that could expose assets to identified threats (e.g., lack of encryption, weak passwords, outdated systems).
Assess how each vulnerability could be exploited.
For each risk, assess the likelihood of occurrence (e.g., high, medium, low).
Assess the potential impact on the organization if the risk materializes (e.g., financial loss, reputational damage, compromise of sensitive data).
Assign a risk rating (e.g., high, medium, low) based on likelihood and impact.
Prioritize risks that require immediate attention or mitigation.
Select appropriate security controls to mitigate the identified risks.
Review standards such as ISO/IEC 27001, NIST, or CIS for control options.
Determine which controls are relevant to the identified risks and comply with any sector-specific regulations (e.g., HIPAA for healthcare).
Choose security controls that mitigate the identified risks effectively (e.g., firewalls, encryption, multi-factor authentication, access control systems).
Ensure that selected controls are feasible given the organization's resources and public sector constraints.
Document each control selected, including details on how it will mitigate the corresponding risk.
Specify roles and responsibilities for implementing each control.
Create an implementation plan that details timelines and resources needed for control implementation.
Identify any dependencies or prerequisites for implementing each control.
Create formal documentation to establish security practices.
Draft a high-level Security Policy that outlines the organization's commitment to information security.
Include key principles such as confidentiality, integrity, and availability.
Define how user access will be granted, modified, or revoked.
Outline password policies, including complexity requirements and rotation frequency.
Define what constitutes a security incident.
Create a step-by-step procedure for reporting, responding to, and mitigating security incidents.
Identify roles and responsibilities during incident handling.
Establish procedures for regular data backups.
Define roles responsible for performing backups and verify recovery capabilities through testing.
Develop a training plan to ensure employees understand security policies and their responsibilities.
Create awareness materials (e.g., posters, guidelines) to encourage security best practices.
Ensure all policies and procedures are reviewed and approved by management.
Set a schedule for periodic reviews and updates of the documents.
Compile all documentation into an ISMS manual.
Compile all policies, procedures, risk assessments, and control documentation into a structured manual.
Include an overview of the ISMS, its scope, and objectives.
Clearly define roles and responsibilities for maintaining and improving the ISMS.
Include a section on leadership commitment to the ISMS.
Provide a detailed explanation of the risk assessment process used.
Include templates or forms used in the risk assessment process.
Define how the effectiveness of the ISMS will be monitored and measured.
Include key performance indicators (KPIs) for information security.
Conduct a review of your ISMS and prepare a presentation for stakeholders.
Review all components of the ISMS to ensure alignment with the defined scope and objectives.
Verify that all risks have been appropriately assessed and mitigated.
Ensure all security policies and procedures are documented clearly and comprehensively.
Develop a presentation that summarizes the ISMS scope, risk assessment findings, selected controls, and security policies.
Highlight key risks and the measures taken to mitigate them.
Identify areas for future improvement and ongoing monitoring.
Present the ISMS to key stakeholders (e.g., management, IT team, department heads).
Gather feedback and make necessary adjustments based on their input.

Remember to think critically about each step and make reasonable assumptions when faced with information gaps. This project will help you develop practical skills in risk assessment, policy development, and applying a risk-based approach to information security in a public sector context.
