# Implementing Network Traffic Analysis with Arkime ## When to Use - When deploying or configuring implementing network traffic analysis with arkime capabilities in your environment - When establishing security controls aligned to compliance requirements - When building or improving security architecture for this domain - When conducting security assessments that require this implementation ## Prerequisites - Familiarity with network security concepts and tools - Access to a test or lab environment for safe execution - Python 3.8+ with required dependencies installed - Appropriate authorization for any testing activities ## Instructions 1. Install dependencies: `pip install requests` 2. Configure Arkime viewer URL and credentials. 3. Run the agent to query Arkime sessions and analyze traffic: - Search sessions by IP, port, protocol, or expression - Download PCAP data for forensic analysis - Detect C2 beaconing via connection interval analysis - Identify DNS tunneling through query length statistics - Flag connections to known-bad TLS certificate issuers ```bash python scripts/agent.py --arkime-url https://arkime.local:8005 --user admin --password secret --output arkime_report.json ``` ## Examples ### Beaconing Detection ``` Source: 10.1.2.50 -> 185.220.101.34:443 Sessions: 288 over 24 hours Avg interval: 300s, Jitter: 4.2% Verdict: HIGH confidence C2 beaconing (jitter < 5%) ```
