$8-15 USD / hour

We are seeking an experienced cybersecurity analyst with expertise in network traffic analysis and defensive scripting. The task involves analyzing a PCAP file containing suspicious traffic targeting critical infrastructure. The goal is to identify potential attack types, assess their impact, and propose mitigation strategies. Additionally, we require the development of a Bash script capable of automating key network defense tasks, such as blocking malicious IPs and detecting abnormal activities. The script should be functional on a Kali Linux VM and include well-documented comments. Deliverables: 1. A detailed technical report summarizing the analysis, including attack identification, risk assessment, and proposed mitigation strategies. 2. A working Bash script implementing defensive measures with clear documentation. Candidates with expertise in cybersecurity, packet analysis tools (like Wireshark), and scripting in Linux environments are encouraged to apply. Familiarity with frameworks like NIST or ISO 27001 for risk assessment is a plus. The ability to provide high-quality, original work is essential. This phrasing frames the work as a cybersecurity project rather than an assignment, emphasizing technical deliverables and professional requirements.
