Cybersecurity Engineer &ndash; DDoS Traffic Simulation, Data Attack Analysis &amp; Dataset DevelopmentJob OverviewWe are seeking a highly skilled Cybersecurity Engineer with strong expertise in network attack simulation, Layer 3 &amp; Layer 4 DDoS traffic generation, feature engineering, and dataset development. The ideal candidate will design and execute end-to-end pipelines for generating high-fidelity network datasets used for research, detection modeling, and cybersecurity system evaluation. This role involves hands-on work with tools such as Hping3, Mininet, Wireshark/tcpdump, and CICFlowMeter, and requires strong analytical skills for validating dataset quality and integrity.Key Responsibilities1. DDoS Attack Simulation &amp; Traffic Generation<ul><li>Design and execute Layer 3 and Layer 4 DDoS attack scenarios using tools such as Hping3, Mininet, and custom traffic scripts.</li><li>Simulate at least 10 realistic DDoS attack vectors, including SYN floods, UDP floods, ICMP floods, TCP fragmentation attacks, and other volumetric or protocol-abusing scenarios.</li><li>Generate controlled normal and malicious network traffic while maintaining a clean, reproducible simulation environment.</li></ul>2. Dataset Pipeline Development<ul><li>Design, implement, and document a complete dataset generation pipeline, including:</li><li>Network topology setup (Mininet/virtual lab)</li><li>Attack execution and traffic orchestration</li><li>PCAP capture using tcpdump/Wireshark</li><li>Flow-based feature extraction with CICFlowMeter</li><li>CSV dataset generation and metadata alignment</li><li>Ensure the pipeline is modular, reproducible, and version-controlled.</li></ul>3. Flow Labeling &amp; Dataset Composition<ul><li>Generate, balance, and label normal (60%) and attack (40%) traffic flows.</li><li>Assign accurate ground-truth labeling for all flows across the 10 selected scenarios.</li></ul>4. Feature Engineering &amp; Analysis<ul><li>Extract 70+ network features, including but not limited to:</li><li>Source IP entropy, TTL variance, packet size distribution</li><li>Flow IAT statistics</li><li>TCP/UDP flag patterns</li><li>SYN/ACK ratios and incomplete handshake indicators</li><li>Port entropy, burstiness, flow duration metrics</li><li>Perform exploratory data analysis to assess feature distributions, correlations, anomalies, and dataset completeness.</li></ul>5. Dataset Quality Validation<ul><li>Validate dataset correctness by analyzing:</li><li>Feature integrity and consistency</li><li>Corruption or missing-flow detection</li><li>Correlation matrices and multicollinearity</li><li>Attack/normal traffic separability</li><li>Produce summary statistics, validation reports, and visualizations as required.</li></ul>6. Documentation &amp; Deliverables<ul><li>Deliver a complete, well-structured research package, including:</li><li>All PCAP files, CSV datasets, and extracted features</li><li>All simulation and attack scripts</li><li>Step-by-step technical documentation</li><li>Architecture diagrams, flow charts, and reproducibility notes</li><li>Ensure the dataset meets standards of originality, academic integrity, and reproducibility.</li></ul>Required Skills &amp; Qualifications<ul><li>Bachelor&rsquo;s or Master&rsquo;s degree in Cybersecurity, Computer Science, Network Engineering, or related field.</li><li>Strong understanding of TCP/IP, L3/L4 protocols, and DDoS attack fundamentals.</li><li>Hands-on experience with Hping3, Mininet, CICFlowMeter, tcpdump, and Linux-based network tools.</li><li>Experience with dataset development, feature engineering, and network traffic analysis.</li><li>Proficiency in Python or Bash for automation and workflow scripting.</li><li>Familiarity with packet analysis, flow analysis, and security research methodologies.</li></ul>Preferred Qualifications<ul><li>Experience with network simulation frameworks or SDN.</li><li>Background in cybersecurity research or academic dataset development.</li><li>Knowledge of anomaly detection, ML-based intrusion detection systems (IDS), or traffic classification.</li></ul>Contact person: Gray-95661 33822Job Types: Part-time, Freelance, Volunteer Contract length: 1 monthPay: From ₹10,000.00 per monthWork Location: Remote
