Über diesen Service
Need enterprise-grade network visibility without commercial licensing costs? As a Cybersecurity graduate specializing in traffic analysis, I deploy and fine-tune open-source IDS/IPS (Snort 3 / Suricata) tailored to your architecture.
I work natively with these platforms to establish defensive barriers, eliminate alert fatigue, and capture clean forensic telemetry.
What I Deliver:
- Turnkey Deployments: Flawless installation of Snort 3 or Suricata on Linux (Ubuntu, Debian, Rocky Linux) or pfSense firewall appliances.
- Custom Rule Engineering: Signature design to identify malicious patterns (SQLi, shellcodes, lateral movement) without degrading throughput.
- False-Positive Tuning: Expert optimization of rulesets (Emerging Threats, Talos) to reduce logging noise and alert fatigue.
- SIEM Integration: Proper setup of unified logging formats (EVE JSON, unified2) for ingestion into Splunk, ELK, or Wazuh dashboards.
Whether you need a passive monitor on a TAP/SPAN port or inline blocking IPS mode, I build it with production stability.
Please message me with your OS, network topology, and security objectives before ordering.

FAQ
Which IDS/IPS engine should I choose for my network?
It depends on your infrastructure. Suricata is highly multi-threaded and excels at high-throughput deep packet inspection and native EVE JSON logging. Snort 3 offers a powerful, modern single-threaded architecture with excellent modularity. I will analyze your hardware specs and traffic volume to re
Can you write rules to detect specific CVEs or zero-day threats?
Yes. I can write custom rules tailored to precise threat vectors, including SQL injection (SQLi), remote code execution (RCE) payloads, unauthorized scanning, and anomalous protocol behaviors. Provide the packet capture (pcap) or target vulnerability details, and I will engineer the signature.
How do you prevent false positives from overwhelming my logs?
I perform fine-tuning by analyzing your baseline network traffic and applying thresholding, suppression, and custom rule modifications. This minimizes alert fatigue, ensuring your system ignores legitimate traffic patterns and only flags valid, actionable security incidents.
Do you configure inline blocking (IPS) or just monitoring (IDS)?
I configure both. I can deploy a passive Intrusion Detection System (IDS) utilizing TAP/SPAN port mirroring for zero network friction, or an active Intrusion Prevention System (IPS) using inline mode (NFQUEUE/AF_PACKET) to drop and block malicious traffic at the gateway level.
