Project Part 8: Windows Hardening Recommendations Scenario As a Security

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 founds 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.

In today's increasingly complex cybersecurity landscape, implementing robust hardening techniques is essential to safeguard organizational assets, particularly Windows-based systems and applications. The scenario at Always Fresh illustrates several critical vulnerabilities that require targeted hardening strategies to improve overall security posture.

Implementing Effective Password Policies

The problem of users writing down long, complex passwords near their workstations undermines security by making passwords vulnerable to physical theft or discovery. To mitigate this, organizations should enforce strong password policies that mandate the creation of complex, unpredictable passwords that are resistant to guessing or brute-force attacks. One effective method is deploying Windows Password Policy settings through Group Policy objects (GPOs), requiring minimum password length, complexity requirements, and expiration periods (NIST, 2017). Additionally, implementing Password Managers can promote the use of strong, random passwords without the need for users to memorize them, thus reducing the tendency to record passwords physically.

Ensuring Unique User Accounts Per Role

Assigning each user a unique account tailored to their specific role is fundamental for accountability and access control. Multi-role users should operate separate accounts aligned with each role, following the principle of least privilege. This segregation enhances audit capabilities and limits the scope of potential security breaches. Implementing role-based access control (RBAC) within Active Directory enables precise permissions management, ensuring that users can only access resources necessary for their designated responsibilities (Chen & Zhao, 2019).

Restricting Anonymous Web Application Access

Limiting anonymous access to web servers within the DMZ is vital to prevent unauthorized access to sensitive resources. Configuring IIS (Internet Information Services) or other web server platforms to restrict anonymous authentication can ensure that only authenticated users or systems can access internal resources. Specifically, configuring the web server to disallow anonymous access except for the DMZ servers involves editing the IIS authentication settings to disable "Anonymous Authentication" on protected servers and enable it solely on servers designated for public access. This segmentation minimizes attack vectors and adheres to the principle of network segmentation (Microsoft, 2020).

Authenticating Connections Based on Source Computer and User

Enhancing server authentication to verify both the source computer and user identity provides a layered security approach to mitigate impersonation and unauthorized access. This can be achieved via mutual authentication techniques such as Windows Authentication with Kerberos or implementing IPsec policies for network layer security. IPsec enables the verification of the source IP address and encrypts traffic, providing confidentiality, integrity, and authentication. Additionally, configuring Active Directory to enforce user authentication based on certificate-based or smart card credentials adds further assurance that connections originate from trusted sources (Reed, 2012).

Conclusion

Implementing these hardening techniques—password policies that prevent storage of passwords, multiple dedicated user accounts per role, restricted web server access, and robust server authentication mechanisms—will significantly bolster organizational security at Always Fresh. Each measure addresses specific vulnerabilities and collectively reduces the attack surface, thereby safeguarding sensitive data and critical infrastructure from malicious actors.
