Scenarios: A Security Administrator For Always Fresh You Hav ✓ Solved
Scenarioas A Security Administrator For Always Fresh You Have Been In
Scenario as a security administrator for Always Fresh, you have been instructed to ensure that Windows authentication, networking, and data access are hardened. This will help to provide a high level of security. The following are issues to be addressed through hardening techniques: Previous attempts to protect user accounts have resulted in users writing long passwords down and placing them near their workstations. Users should not write down passwords or create passwords that attackers could easily guess, such as words found in the dictionary. Every user, regardless of role, must have at least one unique user account. A user who operates in multiple roles may have multiple unique user accounts. Users should use the account for its intended role only. Anonymous users of the web server applications should only be able to access servers located in the demilitarized zone (DMZ). No anonymous web application users should be able to access any protected resources in the Always Fresh IT infrastructure. To protect servers from attack, each server should authenticate connections based on the source computer and user.

Introduction
In the contemporary cybersecurity landscape, organizations like Always Fresh must implement robust hardening techniques to safeguard their infrastructure against evolving threats. This report addresses critical security issues related to user authentication, password management, role segregation, and network access controls. By adopting these hardening strategies, Always Fresh can significantly enhance its security posture, protecting sensitive data and maintaining operational integrity.
Password Security and User Account Management
One of the primary concerns identified involves users writing down long passwords or choosing easily guessable ones. To combat this, implementing a comprehensive password policy is essential. This policy should enforce complex password requirements—such as a minimum of 12 characters, including uppercase and lowercase letters, numbers, and special symbols—making password guessing significantly more difficult (NIST, 2017). Additionally, encouraging the use of password managers can help users generate and store complex passwords securely, reducing the tendency to write passwords down (Joshi et al., 2020).
Furthermore, ensuring that each user has a unique account is vital for accountability and access control. Users operating in multiple roles should be provided with distinct accounts tailored to each role. This segregation minimizes the risk of privilege escalation and prevents users from accessing resources outside their authorized scope (Chia, 2018). Role-based access control (RBAC) can further enforce policies to restrict users to only the data and applications necessary for their responsibilities, thereby limiting potential attack vectors.
Web Server Access Restrictions
Addressing the issue of anonymous users accessing web servers involves configuring the web server to restrict anonymous access exclusively to servers within the DMZ. This can be achieved through specific access control lists (ACLs) and authentication modules that enforce identity verification for external users, thereby preventing unauthorized access to internal resources (Microsoft, 2021). Employing SSL/TLS encryption also ensures that data transmitted remains confidential and tamper-proof.
Moreover, sensitive internal servers should require strong, authenticated access—using methods such as client certificates or integrated Windows authentication—based on the identity of the source computer and user. This multi-factor validation enhances security by verifying the legitimacy of each connection, thwarting impersonation attempts (Kumar & Singh, 2019). Setting up network policies and firewall rules that restrict access based on source IP addresses or subnet ranges further mitigates risks associated with unauthorized access.
Network Hardening and Authentication
Hardening network configurations involves deploying security protocols such as IPsec or SSH for encrypted communication channels, reducing the risk of interception or man-in-the-middle attacks. Network segmentation ensures that critical resources are isolated within secure zones, making lateral movement by attackers more difficult (Fahmida et al., 2020). Alongside, implementing centralized authentication systems like Active Directory enables consistent enforcement of security policies across all servers and endpoints.
Integrating multi-factor authentication (MFA) adds an additional layer of security, requiring users to provide multiple forms of verification before gaining access. This reduces the likelihood of credential compromise leading to unauthorized access. Regular patching and updates of network devices, along with security audits, ensure vulnerabilities are mitigated promptly (Alabduljalil & Dundar, 2018).
Conclusion
The security enhancements outlined—ranging from robust password policies and role-based account segmentation to strict access controls and network protections—are essential in safeguarding Always Fresh’s infrastructure. These measures not only prevent potential breaches but also facilitate compliance with industry standards and best practices. Implementing these hardening techniques will fortify the organization’s defenses, ensuring operational resilience against cyber threats.
