I’m looking for a specialist to run a full health-check on my Local Area Network. The priority is to verify that everything works as intended and to pinpoint any performance bottlenecks that might slow users down. Security is being handled separately, so your focus will be strictly on functionality and performance. The job involves testing end-to-end connectivity, measuring throughput and latency at peak and off-peak times, and confirming that current configurations on switches, routers, and access points align with best practices. I expect you to use industry-standard network diagnostic tools—think Wireshark, iPerf, or SolarWinds—but you’re free to bring in any utilities you trust as long as the results are clearly documented. Deliverables • A concise repo...

I have already completed the technical investigation of a recent security alert: the endpoint protection platform flagged an executable that tried to tamper with system files and phone home to an external server. I verified the hash, monitored live-system behaviour, confirmed the activity as malicious, quarantined the file and rescanned the host to ensure it is now clean. What I need next is a professionally written incident report that translates those raw findings into a clear narrative for both management and technical stakeholders. The document should outline the timeline of events, the investigation methodology, indicators of compromise, remediation actions taken, and practical recommendations to harden the environment against similar threats. Where helpful, map tactics to MITRE ATT&...

You are a senior cybersecurity + machine learning engineer. Build a practical, runnable, end-to-end Transformer-based Web Application Firewall (AI-WAF) prototype suitable for Smart India Hackathon / ISRO SIH demonstration. The system must implement the full pipeline: Log Ingestion → Parsing → Normalization → Tokenization → Transformer Training → Multi-Class Attack Classification → Anomaly Scoring → Real-Time Non-Blocking Inference → Alerting & Logging → Incremental Fine-Tuning ======================================== 1. CORE FUNCTIONAL REQUIREMENTS ======================================== A. Multi-Class Attack Detection The Transformer model must classify HTTP requests into: - BENIGN - SQL_INJECTION - XSS - COMMAND_INJECTION - PATH_TR...

I hold written authorization from the system owner and need an experienced ethical-hacking professional to carry out a controlled breach of our production environment. The assignment goes beyond a traditional penetration test: I want you to replicate a real-world, end-to-end intrusion scenario so we can measure how our monitoring, logging and incident-response teams react under pressure. Scope • Obtain initial access using any non-destructive vector you discover (phishing simulation, misconfigurations, credential weakness, etc.). • Laterally move, escalate privileges and demonstrate data access without altering or deleting information. • Leave tamper-proof evidence (flags) in pre-agreed directories so we can verify compromise. • Conclude with a thorough report that det...

I’m ready to move from concept to a fully functioning Wide Area Network and need an experienced networking specialist to guide every step. The job starts with assessing my current sites and bandwidth needs, then designing a scalable WAN topology that keeps latency low and uptime high. From there you’ll source or specify the right hardware, configure routing, implement security policies, test end-to-end connectivity, and leave me with clear documentation so my team can handle routine maintenance. If you’ve rolled out multi-site WANs before and can communicate technical details in plain language, let’s talk timelines and milestones.

I’m ready to bring in a security specialist to run a thorough, manual penetration test on my live e-commerce application. Automated scanners aren’t enough for this engagement—I need human-driven testing that uncovers real-world attack paths. Here’s what I’m looking for: • A full manual assessment covering all SQL Injection, Cross-site Scripting (XSS) and Cross-site Request Forgery (CSRF),Web Application Penetration Testing , Network Penetration Testing Services External or Internal, Web Services Testing, API Testing • Exploitation-level proof of concept for every confirmed issue, with clear, reproducible steps. • A concise risk-ranked report that separates critical, high, medium and low findings, followed by practical remediation advice writ...

I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to imp...
