Performing Ics Asset Discovery With Claroty

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(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}

1. Plan Operations — Define objectives, scope, and success criteria for ics asset discovery operations.
2. Prepare Environment — Set up tools, access, and data sources required for ics asset discovery.
3. Execute Core Workflow — Use claroty to perform ics asset discovery operations following established procedures.
4. Validate Results — Verify that results meet quality standards and objectives.
5. Report Findings — Document results, observations, and recommendations.
6. Follow Up — Track remediation actions and verify fixes where applicable.

Tools

• claroty — Primary tool for this skill
• Analysis Platform — Data processing and visualization
• Collaboration Tools — Team coordination and knowledge sharing

Process

1. Design — Define interface, identify patterns, plan implementation
2. Implement — Write code following existing conventions, add tests
3. Verify — Run tests, check integration, validate behavior

Verification

• All ics asset discovery procedures executed completely and documented
• Findings validated against multiple data sources
• False positives identified and filtered
• Results documented with evidence and timestamps
• Recommendations provided with risk-based prioritization
