The problem Nexus Sentinel - Cyber Threat Monitoring System solves

Nexus Sentinel aims to solve the unique problem of providing real-time visibility into global cyber threats while offering several key differentiators compared to existing solutions.

1. Empowering Non-Technical Staff, Startups, and Organizations: Traditional cybersecurity measures are often complex and require specialized expertise to operate effectively. However, Nexus Sentinel simplifies the process by providing an intuitive user interface and easy-to-understand visualizations.

2. Avoiding Direct Hits from Hackers: Many existing solutions primarily target cybersecurity professionals and technical teams. However, Nexus Sentinel provides real-time global threat visibility and geolocation enrichment to understand the origin of attacks, identify potential vulnerabilities, and proactively implement defenses.

3. Customizable Geolocation Enrichment: With the integration of PowerShell scripts and third-party APIs like IPGeolocation.io, Nexus Sentinel enriches attack logs with geolocation data. This enables organizations to gain detailed insights into the geographic origins of attacks, identifying country-level patterns and understanding the scope and impact of cyber threats.

4. Simplifying Cybersecurity Logs Analysis: Another unique aspect of Nexus Sentinel is its ability to simplify cybersecurity logs analysis. Traditional log analysis processes can be complex and time-consuming, requiring technical expertise and specialized tools. Nexus Sentinel streamlines this process by providing an intuitive map-based graphical user interface (GUI).

5. Actionable Insights and Proactive Defense Strategies: The visualization of attack data on a world map allows users to understand the geographical distribution of threats and identify emerging patterns. This information helps organizations make data-driven decisions, prioritize security measures, and allocate resources effectively.

Challenges we ran into

Here are the key challenges we faced and how we overcame them:

1. Automation of Script: One of the difficulties we faced was automating the script for log extraction, transformation, and API integration. It took careful thought and implementation to create a script that could easily extract IP addresses from logs, submit them to the IPGeolocation.io API, and receive geolocation data. We needed to make sure the script could handle enormous amounts of log data efficiently and effectively. We were able to design an automated script that seamlessly integrated into the Nexus Sentinel workflow after extensive testing and iterations.

2. Log Analysis Query Optimization: Another difficulty we encountered was optimizing log analysis queries for efficient and accurate results. Analyzing vast amounts of log data and extracting useful insights necessitated the development of complicated queries and ensuring that they performed within acceptable performance limitations. We spent a substantial amount of effort fine-tuning the log analysis queries to ensure they were fast and accurate. We established an efficient and dependable log analysis procedure through iterative testing and query optimization approaches.

3. Integration and Compatibility: Integrating various technologies and ensuring compatibility between different components was a challenge. It leverages Azure Sentinel, Power Shell scripting, and API, requiring careful coordination and configuration. We encountered compatibility issues between components and API dependencies. We overcame this challenge through diligent testing, version control, and comprehensive documentation, ensuring seamless integration and compatibility across the entire solution stack.
