Waving Hand Hi there, I'm Anisur Rahman

Cybersecurity Student | Networking & Network Security

I am a Cybersecurity student focused on securing network infrastructures, analyzing traffic behavior, and streamlining incident response. I bridge the gap between foundational networking concepts and real-world defense by developing automated security solutions, conducting vulnerability assessments, and managing system operations. My core focus lies in proactively identifying risks and visualizing network telemetry to mitigate threats before they escalate.


Computer Tech Stack

Welcome to the battle deck - here's the arsenal I deploy across network defense, SIEM monitoring, vulnerability assessment, and security automation.

Rocket Featured Project: Sentinel

Custom Network Intrusion Detection & Prevention System (NIDS/NIPS & SIEM)

Engineered a robust, automated network defense tool designed to identify and mitigate high-volume volumetric attacks in real-time.

  • Dynamic Mitigation: Upgraded a NIDS to a fully functional NIPS, executing dynamic iptables firewall rules to instantly drop malicious IPs in <100ms after breaching a predefined 10-packet volumetric threshold.
  • Threat Validation: Validated threat detection logic against simulated ICMP Ping Floods exceeding 1,000+ packets/minute in an isolated Kali/Metasploitable environment, maintaining a 0% false-positive rate.
  • SIEM Integration: Engineered an automated incident logging module that extracts 4 key telemetry data points into CSV reports, directly ingesting into Splunk Enterprise.
  • Live Dashboards: Constructed a live SOC operations dashboard writing 3 advanced SPL queries to monitor total mitigated threats, IP attack volumes, and live attack timelines.

Construction Ongoing Project: DirectDrop

Core Networking & Security CLI Tool

My current ongoing project serves as a hands-on sandbox for engineering and testing the following core concepts:

  • Core Networking: 3-Way Handshake, UDP Routing, and Private IP Addressing & NAT.
  • Network Architecture: Port Binding & Listening Sockets.
  • Application Security: Directory Traversal Prevention and Threat Modeling within the HTTP Protocol.
  • Development: Building a functional CLI tool from the ground up.

Briefcase Experience

Cyber Security Intern | Vidyashala 06/2025 - 08/2025 (Remote)

  • Monitored a network of 60+ endpoints and analyzed over 500+ weekly network logs to detect unusual activity, successfully identifying and mitigating 20+ potential security risks before escalation.
  • Maintained 15+ critical compliance documents and collaborated with a 4-person technical team to enforce cybersecurity policies, increasing audit adherence by 15%.

Scroll Certifications & Ongoing Research

  • Level Up Cybersecurity with Generative AI – IBM
  • Constantly exploring new threat vectors by conducting and documenting controlled hacks within isolated home lab environments. Check out my repositories for detailed project hack reports!
