Acme Enterprise Scenario Residency Weekacme Enterprise Is A Private Co

Acme Enterprise is a private company preparing for an initial public offering (IPO). It must ensure compliance with GDPR, PCI DSS, and SOX. The company operates in water purification using advanced technologies and needs a thorough risk assessment of its IT infrastructure. The assessment should identify threats and exposures across various domains—including perimeter security, network security, endpoint security, application security, data security, operations, and policy management—and provide mitigations to support a successful IPO.

Introduction

The process of conducting a comprehensive risk assessment for Acme Enterprise is vital to ensure regulatory compliance and protect critical assets before its IPO. This paper evaluates the current state of Acme’s IT infrastructure across seven key areas: perimeter security, network security, endpoint security, application security, data security, operations, and policy management. Based on the identified vulnerabilities, it offers targeted mitigation strategies to reduce risks effectively.

Perimeter Security

Acme's perimeter security relies on two dual dynamic Stateful Inspection firewalls configured for high availability and port address translation (PAT). While these firewalls provide foundational security, several gaps exist. The use of a single public IP address (200.200.200.1) mapped to an internal IP range creates a potential point of failure, and insufficient segmentation through DMZs limits the ability to isolate critical assets from external threats. Additionally, the absence of intrusion detection and prevention systems (IDS/IPS) leaves the network vulnerable to reconnaissance and attack attempts.

Mitigations should include deploying IDS/IPS within the perimeter, establishing dedicated DMZs for web and application servers, and implementing additional firewall rules with strict ingress and egress filtering. Enhancement of threat intelligence integration and regular firewall rule audits can further bolster perimeter defenses (NIST, 2018).

Network Security

The network architecture employs a collapsed core design, consolidating routing and security controls at the distribution layer. Wireless security is managed via WPA2, which, while standard, has vulnerabilities if not configured correctly. The existing VLAN segmentation (User and R&D) provides some isolation but may not suffice against internal threats or unauthorized lateral movement, especially given static IP assignments and broad access permissions.

To improve network security, Acme should consider implementing 802.1X authentication for device access, deploying network access control (NAC) solutions, and leveraging network segmentation with firewalls between VLANs. Transitioning from static to dynamic IP management with DHCP and employing network monitoring tools like NetFlow can aid in detecting anomalous activity (Cisco, 2020).

Endpoint Security

Acme’s endpoint security is inconsistent and outdated. MAC systems are managed via JAMF, but Windows devices rely on end-user initiative for patches and updates, and the current signature-based antivirus (McAfee) lacks centralized oversight. Such disjointed defenses expose the organization to malware, ransomware, and data breaches.

Implementing endpoint detection and response (EDR) tools, enforcing automated patch management, and establishing centralized endpoint security management are essential. Upgrading to next-generation antivirus solutions with behavioral analytics and integrating with SIEM systems can enhance detection and response capabilities (NIST, 2021).

Application Security

Application development and monitoring are unstructured, with no formal secure coding practices or oversight. The server farm hosts multiple services, including media servers, content management, and databases, but lacks virtualization or modern security controls. This increases risks of code vulnerabilities, unauthorized access, and data breaches.

Adopting secure SDLC methodologies, conducting regular vulnerability assessments, and implementing application firewalls (WAFs) are recommended. Establishing continuous monitoring and automated alerting can help detect anomalies early, thereby reducing attack surfaces (OWASP, 2022).

Data Security

Data governance is weak; information is not classified, and access relies solely on single-factor authentication. The use of self-signed certificates for encryption, absence of encryption for data at rest and in transit, and lack of data loss prevention (DLP) tools pose significant risks, especially since financial and PII data are stored.

To mitigate this, Acme should implement multi-factor authentication (MFA), adopt data classification policies, and enforce encryption standards aligned with industry best practices (NIST SP 800-111). Deploying DLP solutions and establishing data access controls based on roles can substantially secure sensitive data.

Operations and Policy Management

A dedicated security team reports to IT, with policies that are not aligned with established frameworks like NIST CSF or COBIT 5. Without formalized procedures, incident response, change management, and continuous monitoring are deficient. These gaps could impede threat detection and response, increasing organizational risk.

Implementing standardized security frameworks, documenting policies, and conducting regular security awareness training are critical. Integrating automated security monitoring tools will enable proactive risk management aligned with recognized standards (ISO/IEC 27001, 2022).

Conclusion

Acme’s current cybersecurity posture reveals multiple vulnerabilities across all domains. To ensure a smooth IPO process and compliance with GDPR, PCI DSS, and SOX, targeted mitigations must be implemented promptly. These include upgrading perimeter defenses with IDS/IPS, enhancing network segmentation, centralizing endpoint security management, adopting formal secure coding practices, encrypting and classifying data, and formalizing security policies adhering to recognized frameworks. Continuous risk management and regular assessments are vital as the organization evolves towards public status.
