This project focuses on securing operating systems and applications by implementing access controls, security policies, file system permissions, and system monitoring techniques. It includes Active Directory management, NTFS security configurations, Linux system hardening, and network traffic analysis to mitigate security risks.

🔎 Skills Learned:

✅ Managing domain users & access control policies
✅ Implementing security policies via Group Policy & NTFS permissions
✅ Performing security assessments using MBSA & BPA
✅ Hardening Windows & Linux file systems
✅ Network traffic analysis with TCP Dump & Linux monitoring tools

🛠 Tools Used:

🔹 Windows Server: Group Policy, NTFS, Active Directory
🔹 Security Assessment: Microsoft Baseline Security Analyzer (MBSA), Best Practices Analyzer (BPA)
🔹 Virtualization & Remote Access: VMware vSphere Client, PuTTY
🔹 Linux Security & Network Tools: TCP Dump, Uname, Icacls (Windows File Permissions)
