Azure SOC and HoneyNet

• Cloud Security Implementation: Built HoneyNet and SOC on Microsoft Azure, provisioning vital resources. Deployed Azure Sentinel SIEM for comprehensive security coverage.
• Cybersecurity Assessment: Exposed resources to the internet, gathering attack data for 24 hours. Analyzed traffic patterns, identified vulnerabilities, and assessed threats.
• Security Enhancement: Hardened environment based on assessment insights. Monitored secured environment for an additional 24 hours, validating implemented security measures.
• Data Analysis and Reporting: Extracted and analyzed log data, creating a concise spreadsheet. Summarized findings, showcasing the project's impact on cybersecurity posture.

Cyber Security Virtual Lab

• Installed and configured Opnsense Firewall on a sandbox network.
• Installed and configured Kali Linux to connect to an internal network and Opnsense firewall.
• Installed an Intrusion detection system and Intrusion prevention system onto Opnsense firewall. Wrote and installed our own set of rules on our Intrusion detection system and intrusion prevention system.
• Performed a reconnaissance, port scan using Nmap and watched the IDS/IPS system identify stealthy SYN scan threats on our system.

Cyber Attack World Map

• Used custom PowerShell script to extract metadata from Windows Event Viewer to be forwarded to third party API in order to derive geolocation data.
• Configured Log Analytics Workspace in Azure to ingest custom logs containing geographic information. Configured Custom Fields in Log Analytics Workspace with the intent of mapping geo data in Azure Sentinel.
• Configured Azure Sentinel workbook to display global attack data (brute force) on world map according to physical location and magnitude of attacks.

Vulnerability Management Experiment

• Installed and configured Nessus Essentials to perform credentialed vulnerability scans against Windows 10 Hosts.
• Implemented Vulnerability Management Function on sandbox networks.
• Conducted vulnerability assessments with Nessus; remediated vulnerabilities.
• Developed automated remediation process to preemptively deal with vulnerabilities stemming from Windows updates and third-party software.
