Introduction

In the increasingly interconnected landscape of modern business, safeguarding information assets through robust security frameworks is essential. Big Tire Transport, a large logistics company operating across the United States, faces distinct security challenges following a recent merger. The company’s dispersed locations, diverse hardware and software environments, and prior security incidents underscore the need for a strategic approach to infrastructure assessment, risk management, access control, remote access, physical security, and ongoing security monitoring. This paper offers a comprehensive plan to address these critical areas, supporting Big Tire’s objective of establishing a secure, efficient, and compliant operational environment.

Part 1: Infrastructure and Risk Assessment Plans

Infrastructure Assessment Plan

The primary purpose of the infrastructure assessment is to inventory and evaluate all hardware, software, network components, and data assets across all company locations. This comprehensive evaluation enables identification of vulnerabilities, outdated equipment, and gaps in security controls. The scope includes company headquarters in Kansas City, along with Minneapolis, Memphis, Reno, and El Paso facilities, each with varying levels of hardware modernization and software updates.

The assessment will follow these major steps: First, form a cross-functional assessment team to facilitate data collection and analysis. Next, conduct physical audits of hardware assets, questioning the lifecycle status and maintenance history. Then, document network architecture, including topology diagrams and configurations of routers, switches, firewalls, servers, and endpoints. Subsequently, evaluate the software environment, with particular attention to outdated or unsupported systems. Finally, compile findings into a detailed report highlighting assets, vulnerabilities, and security posture.

The assessment will be scheduled over a three-month period to ensure thorough coverage of all sites, with periodic progress reviews. Resource requirements include technical staff, assessment tools, network mapping software, and access to all facilities.

IT Risk Assessment Plan

The purpose of the risk assessment is to identify, analyze, and prioritize threats and vulnerabilities that could compromise company operations, data confidentiality, and integrity. This process supports risk mitigation and informed decision-making.

The scope encompasses all IT assets, including servers, network devices, endpoints, and data repositories across the locations. Risks specific to the company’s environment include cyberattacks (e.g., ransomware, insider threats), hardware failure, data loss, and physical security breaches.

The risk assessment will follow these steps: First, inventory all assets and categorize them based on sensitivity and importance. Next, identify potential threats and vulnerabilities through interviews, vulnerability scans, and historical incident reviews. Then, evaluate risks by analyzing likelihood and impact, employing qualitative and quantitative methods. Prioritize risks based on their severity to guide resource allocation for mitigation. Finally, document findings, including recommended security controls and contingency plans.

This assessment is scheduled to occur concurrently with the infrastructure assessment, with results informing security enhancement plans. It requires collaboration with IT personnel, security specialists, and facility managers.

Part 2: Role-Based Access Control (RBAC) and Single Sign-On (SSO)

RBAC Implementation Plan

The goal of the RBAC implementation is to streamline access management, reduce administrative overhead, and enhance security by assigning access rights based on user roles aligned with job functions. The plan begins with defining roles such as Administrative, Accounting, HR, Manager, Sales & Marketing, Driver, and Technical. These roles simplify permissions management, ensuring users only access resources pertinent to their responsibilities.

The technology chosen should support centralized role management and integration with existing Active Directory services. Advantages of RBAC over ACLs include easier administration, consistency in permissions, and minimized risk of privilege creep or accidental exposure.

To implement RBAC, the major steps are: First, analyze current access rights and identify tasks associated with each role. Next, create role definitions and map roles to applications and data repositories. Then, configure access policies within the identity management system or directory services. Subsequent steps involve testing role assignments, training staff, and gradually transitioning from existing access controls.

For future granularity, roles can be further subdivided into sub-roles or permissions, accommodating evolving organizational structures. A proposed schedule includes roles definition in the first month, configuration in months two and three, testing in month four, and phased rollout thereafter.

Single Sign-On (SSO) Feasibility

SSO allows users to authenticate once and access multiple interconnected applications without repeated logins, enhancing user convenience and security. Key technologies include Security Assertion Markup Language (SAML), OAuth, and OpenID Connect. The feasibility of SSO at Big Tire depends on the existing infrastructure’s compatibility with these standards and the integration of cloud-based services with on-premises systems.

Given the diverse applications and environments, implementing a SSO solution leveraging federation standards like SAML appears practical. This approach would centralize authentication, reduce password fatigue, and improve auditability. Challenges include integrating legacy systems and ensuring high availability and security of the authentication service.

The recommendation is to adopt a cloud-based identity provider with support for SAML and OAuth, streamline access during mergers, and future-proof the infrastructure with scalable identity management solutions.

Part 3: Remote Access and Physical Security

Remote Access Strategy

The previous VPN solution proved inadequate due to slow response times. Thus, a more efficient remote access solution such as Virtual Desktop Infrastructure (VDI) or cloud-enabled secure remote desktop services should be adopted. These solutions provide better performance, centralized management, and enhanced security.

Implementation involves deploying a VDI platform, possibly through services like Windows Virtual Desktop, with strict Multi-Factor Authentication (MFA) enforcement. Access policies should include device validation, encryption, and session monitoring to prevent unauthorized access.

Physical Security Enhancements

All company facilities need to upgrade physical security with smart card or programmable locks on offices and garages. These measures facilitate access control, audit trails, and swift response to security incidents. Incorporating biometric authentication, such as fingerprint or facial recognition, especially for high-security areas, will further bolster security. Mobile employees and drivers should utilize token devices or authenticator apps for multifactor authentication (MFA), integrating these factors into access policies for websites and applications.

Implementation steps include installing secure locks, integrating access card readers with security management systems, deploying biometric devices, and establishing policies for false alarm handling and credential issuance. Cost considerations involve hardware procurement, installation, and ongoing maintenance.

Cost-Effective MFA Approach

A balanced MFA solution involves leveraging free or low-cost authenticator apps (e.g., Google Authenticator), hardware tokens for high-value accounts, and biometric methods for on-site personnel. These strategies ensure security without imposing undue burden on users or escalating costs excessively.

Part 4: Testing and Monitoring

Security Testing Plans

Regular testing of RBAC and physical security controls is vital. Penetration testing, vulnerability scanning, and role-based access audits should be scheduled quarterly to identify weaknesses. For physical security, periodic walkthroughs, alarm system tests, and badge audits are essential. These tests will verify access restrictions and identify potential failures or breaches.

Network Monitoring Strategy

Continuous network monitoring across all premises must focus on detecting anomalies, intrusion attempts, and performance issues. Deploying Security Information and Event Management (SIEM) systems and intrusion detection/prevention systems (IDS/IPS) will allow real-time analysis and alerting. Regular review of logs, performance metrics, and incident response drills will enhance readiness and ensure compliance.

Monitoring procedures will include automated alerts for suspicious activity, scheduled log reviews, and incident response protocols. Key metrics encompass unauthorized access attempts, failed login rates, and abnormal traffic patterns. Responsibilities include assigning dedicated security staff and establishing escalation procedures.

Conclusion

Implementing a comprehensive security framework encompassing infrastructure assessment, risk analysis, RBAC, SSO, remote access, physical security, testing, and monitoring will significantly enhance Big Tire’s security posture. This strategic approach, aligned with industry best practices, will protect sensitive data, ensure operational continuity, and facilitate compliance with regulatory standards. Such proactive measures are essential to address current vulnerabilities and prepare for future security challenges.
