Implementing Network Traffic Analysis with Arkime

Name: implementing-network-traffic-analysis-with-arkime
Author: mukul975

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

Install dependencies: pip install requests
Configure Arkime viewer URL and credentials.
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

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%)
