I appreciate your participation in this discussion. For this assignment, create an original post addressing the topic below prior to midnight ET on Wednesday. Continue to follow your classmates’ posts for the remainder of the week and post at least two follow-up messages to your professor’s or classmates’ posts prior to midnight ET on Sunday. Your follow-up posts can add additional insight to a classmate’s opinions or can challenge their opinions. Use examples from your experiences, readings, or from your own research, to support your views, as appropriate. Be sure to read the follow-up posts to your own posts and reply to any questions or requests for clarification.  Thanks!

Instructions:

1. Using Active Directory Group Policy Objects (GPO) or Microsoft Baseline Security Analyzer (MBSA) discuss how one would use them to secure the network.
2. Describe the importance of having privileged and non-privileged states within an organization.
3. List any observations, tips or questions about this lab that would prove helpful to fellow students prior to midnight on Wednesday and comment on other student posts with value added comments (not simply agreeing) by midnight Sunday for full credit consideration.

SOLUTION

Original Post: Securing the Network with GPO and MBSA

Group Policy Objects (GPO) and Microsoft Baseline Security Analyzer (MBSA) are two powerful tools for strengthening organizational security. GPOs allow administrators to centrally manage and enforce security configurations across all users and computers in a Windows domain. For example, an administrator can create policies to require complex passwords, lock accounts after a set number of failed login attempts, restrict access to USB devices, and enforce regular system updates. The advantage of GPOs is consistency—rather than configuring machines individually, administrators can ensure all systems comply with security standards at the domain level, minimizing human error and configuration drift.

MBSA, on the other hand, provides a way to identify vulnerabilities and misconfigurations. It scans systems for missing patches, weak passwords, and deviations from Microsoft’s security recommendations. While MBSA is somewhat dated, it can still highlight areas where policies may not be fully applied or where patches are missing. Used together, GPOs enforce proactive security measures while MBSA offers a reactive audit to verify compliance.

Another key aspect of securing networks is establishing privileged and non-privileged states. Privileged accounts (e.g., domain administrators) should be tightly controlled, monitored, and used sparingly to reduce the attack surface. Non-privileged accounts should be the default for daily tasks such as email, browsing, or document editing. This separation prevents unnecessary elevation of risk and ensures that compromised user accounts cannot easily escalate into full-domain breaches. Many security frameworks, such as the principle of least privilege (PoLP), emphasize this separation as a foundational best practice.

Observations and Tips for the Lab:

• When working with GPOs, test them in a controlled environment before pushing them domain-wide, as misconfigurations can lock out users or disrupt workflows.

• Use descriptive naming conventions for GPOs (e.g., “Password Policy – Enforced”) to avoid confusion when multiple policies are applied.

• Remember that MBSA is best used as a supplementary tool. Pairing it with other vulnerability management platforms can provide a more comprehensive security posture.

Questions for classmates:

• For those of you who primarily rely on GPOs, what are your best practices for ensuring policies don’t conflict with one another?

• Has anyone used MBSA recently, and do you think newer tools like Microsoft Defender for Endpoint provide more value in modern environments?
