Performing Ics Asset Discovery With Claroty

Overview

Cybersecurity skill for performing ics asset discovery with claroty. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "performing ics asset discovery with claroty"

• "Perform comprehensive ICS/OT asset discovery using Claroty xDome platform, lever"

• When gaining initial visibility into an OT environment with unknown or poorly documented assets

• When preparing for an IEC 62443 risk assessment requiring a complete asset inventory

• When onboarding Claroty xDome into a brownfield industrial environment

• When validating existing asset inventory against actual network communications

• When identifying shadow OT devices or unauthorized connections in the control network

Do not use for IT-only asset discovery (use tools like Nessus or Qualys), for active scanning of sensitive PLC networks without vendor approval, or for environments where Claroty is not the deployed platform (see implementing-ot-network-traffic-analysis-with-nozomi).

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Claroty xDome SaaS subscription or on-premises deployment
• Network TAP or SPAN port configured at OT network boundaries (Levels 1-3 of Purdue Model)
• Claroty Edge collector deployed for safe active querying of hard-to-reach network segments
• Integration credentials for CMDB tools (ServiceNow, BMC) if used
• Network architecture diagram showing VLANs, switches, and firewall zones

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs() -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
