Title: Enhancing Enterprise Defense-in-Depth Strategy through Active Directory Group Policy Tweaks

In the realm of cybersecurity, defense-in-depth (DiD) is a widely adopted strategy that aims to provide organizations with multiple layers of security controls. By implementing a series of overlapping defenses at different levels, DiD helps mitigate the risk of successful cyberattacks. Microsoft Active Directory (AD) is a crucial component within enterprise IT infrastructures that can be configured to support a DiD strategy. This paper discusses five essential tweaks that can be made to AD domain group policies to enhance an enterprise defense-in-depth strategy.

1. Enabling Password Complexity:
Setting up password complexity requirements in AD group policies is a fundamental tweak that enhances the DiD strategy by enhancing the security of user credentials. To configure password complexity, the “Password Policy” setting can be utilized in the Group Policy Management Editor. This control enforces the usage of strong passwords by imposing rules such as minimum length, complexity, and regular password change intervals.

Enhanced DiD: By enforcing password complexity, the likelihood of brute-force attacks decreases as the complexity standards increase. Strong passwords help protect user accounts from unauthorized access, reducing the risk of successful attacks such as password guessing or dictionary-based attacks.

2. Implementing Account Lockout Policy:
The Account Lockout Policy tweak involves configuring AD group policies to automatically lock out user accounts after a specified number of failed login attempts. This control can be set using the “Account Lockout Policy” setting in the Group Policy Management Editor. By defining lockout thresholds and durations, organizations can mitigate the risk of brute-force attacks and unauthorized access attempts.

Enhanced DiD: Implementing an account lockout policy as part of the overall defense-in-depth strategy reduces the risk of successful brute-force attacks by impeding attackers’ ability to guess or crack user account passwords. This control adds an additional layer of security by limiting the number of unsuccessful login attempts an attacker can make.

3. Applying Software Restriction Policies:
Software Restriction Policies (SRPs) serve as an effective tweak within AD group policies to enhance the enterprise defense-in-depth strategy. By configuring SRPs, organizations can limit the execution of unauthorized software on endpoints. This control can be configured using the “Software Restriction Policies” setting in the Group Policy Management Editor.

Enhanced DiD: Software Restriction Policies contribute to the defense-in-depth strategy by preventing the execution of unauthorized software, including potentially malicious applications, ransomware, or unauthorized tools. By restricting software execution to trusted sources, organizations can reduce the attack surface and minimize the risk of compromise due to malicious software.
