Mahipal 2fb6a9faff Rewrite 548 skill descriptions to the activation rubric
Each rewritten description now states both what the skill does (concrete
capability, named tools/artifacts) and an explicit when-to-use trigger,
improving agent discovery/activation. Grounded in each skill's own body;
changes confined to the `description` field only (bodies and all other
frontmatter untouched). Produced by a gated audit->rewrite->recheck loop
(548 -> 0 flagged) with a sampled anti-invention check (0 ungrounded).

Schema: 817/817 pass. Framework-ID gate: 0 defects.

implementing-network-traffic-analysis-with-arkime Queries Arkime (formerly Moloch) full packet capture via its API to search sessions, download PCAPs, detect C2 beaconing through connection interval/jitter stats, spot DNS tunneling via query-length analysis, and flag known-bad TLS certificate issuers, using the bundled scripts/agent.py. Use when investigating suspicious network flows or doing full-packet-capture forensics against an Arkime deployment. cybersecurity network-security

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

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%)
