System Security Assessment for Icanread System Inc.'s Network Connection

Icanread System Inc. is an advertising agency specializing in selling ad spaces within their parent company's magazine. The company manages an online database that allows clients to upload and pay for their advertisements intended for magazine placement. Due to the necessity of connecting their database to the parent company's database, a comprehensive security assessment of Icanread System Inc.'s network has been requested. As the designated lead architect for this project, I have conducted an evaluation to ensure the network's security infrastructure effectively safeguards sensitive data and maintains integrity during interconnectivity.

This assessment encompasses a detailed review of existing network architecture, potential vulnerabilities, security controls, and recommendations for strengthening defenses. The primary goal is to establish a secure, reliable, and scalable network environment capable of supporting seamless data exchange with the parent company's database while mitigating risks of unauthorized access, data breaches, and cyber threats.

Network Architecture and Topology Analysis

The current network infrastructure consists of multiple segments including client access points, internal servers, and external connection channels to the parent company's database. The network topology relies on a combination of local area networks (LANs), virtual private networks (VPNs), and cloud-based services. Notably, the connection to the parent company's database is facilitated through a dedicated VPN tunnel, providing an initial layer of encryption and privacy (Stallings, 2017, p. 123). However, the overall security posture depends heavily on how effectively these components are configured and monitored.

Identification of Vulnerabilities and Threats

Despite the existing segmentation, several vulnerabilities could compromise network integrity. These include weak authentication protocols, unpatched software vulnerabilities, potential for malware infiltration, and insider threats. The use of outdated firmware or inadequate access controls at entry points may allow external attackers or malicious insiders to exploit vulnerabilities (Pfleeger et al., 2015, p. 212). Additionally, lack of multi-factor authentication (MFA) increases the risk of credential theft being used for unauthorized access.

Security Controls and Risk Mitigation Measures

Implementing robust security controls is crucial for minimizing risks associated with connecting Icanread's network to the parent company's database. These controls include deploying comprehensive firewall policies that monitor and filter network traffic, intrusion detection systems (IDS) to alert on suspicious activities, and strong encryption standards such as AES-256 for data in transit and at rest (Chen et al., 2018, p. 459). Establishing multi-factor authentication and role-based access controls (RBAC) further restricts access to sensitive data and functions.

Regular patch management and vulnerability assessments are imperative to maintain security resilience. For the VPN connection, implementing rigid security policies—including device authentication, session timeout, and anomaly detection—is vital. Additionally, segmenting the internal network into smaller zones limits lateral movement in the event of a breach (Kerr, 2020, p. 146). Collaboration with the parent company on shared security standards and conducting periodic security audits ensures both entities maintain a synchronized defense posture.

Recommendations for Enhancing Network Security

Based on the assessment, several recommendations are proposed for strengthening Icanread System Inc.'s network security:

• Upgrade existing firewalls with next-generation firewall features that include application awareness and intrusion prevention capabilities.
• Implement multi-factor authentication for all remote access points and administrative privileges.
• Enforce strict password policies and regular credential updates.
• Adopt end-to-end encryption protocols for all data exchanged over the VPN.
• Conduct regular security training for employees to recognize and avoid phishing and social engineering attacks.
• Establish a formal incident response plan to address potential security breaches effectively.
• Carry out routine penetration testing and vulnerability scans to identify and remediate weaknesses proactively.

Conclusion

Securing Icanread System Inc.'s network connection to the parent company's database is vital to safeguarding sensitive client and company information. By implementing layered security measures—including advanced firewalls, encryption, access controls, and employee training—the company can mitigate potential threats and establish a resilient security environment. Continuous monitoring and periodic assessments are necessary to adapt to evolving cyber threats and maintain a high security standard, ensuring the integrity and availability of critical data assets.
