Marcia’s Dry Cleaning needs a comprehensive data security plan to safeguard their database systems, ensuring data integrity, confidentiality, and availability. The following provides a detailed approach based on best practices for data security management in a business environment, covering user access, security policies, threat analysis, disaster planning, and tailored data views.

1. Create tables of the data access needs of your users

To effectively manage data security, it is essential to analyze and define user access requirements. For Marcia’s Dry Cleaning, typical user roles include administrative staff, data entry clerks, maintenance personnel, and management. Each role has different needs regarding data access:

  • Administrative Staff: Require full access to all data and database management functions, including creating, updating, and deleting records.
  • Data Entry Clerks: Need access only to input and modify transactional data related to cleaning orders, customer details, and billing information.
  • Maintenance Personnel: Usually need access to system logs or backup data but not to the transactional or customer data.
  • Management: Require access to summarized reports and analytics but limited direct data manipulation permissions.

With these roles defined, the access needs are mapped into a permissions matrix, which guides the implementation of security controls, ensuring each user has appropriate privileges while minimizing potential risk.

2. Create a security plan that includes authentication and authorization with appropriate general policies and procedures

The security plan should establish robust policies and procedures to control access to the database. Key components include:

Authentication

Implementation of multi-factor authentication (MFA) enhances security by requiring users to verify their identity through multiple methods, such as passwords and one-time codes sent via email or SMS. Strong password policies, including minimum complexity and periodic changes, should be enforced.

Authorization

User roles, as previously determined, define what data and functions each user can access. Role-based access control (RBAC) simplifies permission management by assigning permissions to roles rather than individual users. Views and stored procedures can be used to restrict what data can be accessed or manipulated.

Policies and Procedures

  • Regular password updates and lockout policies after multiple failed login attempts.
  • Periodic review and adjustment of user permissions based on job roles and changes.
  • Login monitoring and audit logs to detect suspicious activities.
  • Training employees on security best practices and data handling procedures.

This security framework promotes a culture of security awareness and enforces controls to prevent unauthorized access and data breaches.

3. Document and define all the aspects of your plan. Provide support for your choices.

Documenting each component of the security plan ensures clarity and consistency. This includes:

  • Explicit description of roles, permissions, and access controls.
  • Justification for selecting MFA over simple password-based security, citing its effectiveness in reducing credential theft.
  • Rationale for implementing role-based permissions and views: these help minimize exposure of sensitive data and simplify permission management.
  • Procedures for onboarding new users, periodically reviewing permissions, and terminating access when employees leave or change roles.
  • Audit trails enable accountability and facilitate incident investigations.

Supporting these choices, industry standards such as ISO/IEC 27001 recommend multi-layered security controls, and principles of least privilege support minimizing data exposure and reducing risk (ISO, 2013; Stallings, 2014).

4. Create a preliminary threat analysis

Potential threats to Marcia’s Dry Cleaning database include:

  • Accidental Data Loss or Corruption: Caused by user errors, system crashes, or hardware failures.
  • Unauthorized Access: External hackers may attempt to breach the system, or internal personnel may misuse privileges.
  • Malware and Ransomware: Malicious software could encrypt or delete data, causing operational disruption.
  • Physical Threats: Fire, flooding, or theft can damage or compromise physical servers and infrastructure.
  • Legal and Regulatory Risks: Data breaches impacting customer data can lead to legal penalties and reputational damage.

Assessing likelihood and impact guides prioritizing security investments and controls. For example, implementing regular backups reduces the impact of data loss, while firewalls, intrusion detection systems, and encrypted connections mitigate external threats.

5. Make a preliminary disaster management plan

The disaster management plan should outline processes to ensure business continuity. Key steps include:

  • Data Backups: Daily incremental backups with weekly full backups stored securely off-site or in the cloud.
  • Recovery Procedures: Clear instructions for restoring databases and systems following events like hardware failures or cyberattacks.
  • Communication Plans: Notify stakeholders, employees, and customers during incidents, providing regular updates.
  • Emergency Access: Temporary elevated permissions or manual procedures should be in place if automated systems fail.
  • Regular Testing: Simulate disaster scenarios periodically to validate recovery steps and update procedures accordingly.

This proactive approach minimizes downtime and data loss, ensuring the business can quickly resume operations after disruptions.

6. Create a view of the data that is tailored to the needs of one of your users

For example, creating a customer-focused view for the sales manager allows access only to customer contact details, recent orders, and billing information, without exposing sensitive employee data or internal system logs.

CREATE VIEW CustomerOverview AS

SELECT CustomerID, CustomerName, Phone, Email, LastOrderDate, TotalSpent


FROM Customers c


JOIN Orders o ON c.CustomerID = o.CustomerID


WHERE o.OrderDate >= DATE_SUB(CURDATE(), INTERVAL 6 MONTH);

This view enables the sales manager to quickly access relevant data, inform decisions, and serve customers effectively, adhering to the principle of least privilege.

7. Copy and paste a complete copy of this report into your journal

This section indicates the final step: maintaining a record of the security plan document for future reference, audits, and continuous improvement.
