# Deploying Edr Agent With Crowdstrike

## Overview

Cybersecurity skill for deploying edr agent with crowdstrike. Follows industry best practices and security standards.

## When to Use

**Trigger phrases:**
- "deploying edr agent with crowdstrike"
- "Deploying CrowdStrike Falcon sensors to Windows, macOS, or Linux endpoints"
- "Configuring Falcon prevention and detection policies for different endpoint grou"
- "Integrating CrowdStrike telemetry with SIEM (Splunk, Elastic, Sentinel) for corr"


Use this skill when:
- Deploying CrowdStrike Falcon sensors to Windows, macOS, or Linux endpoints
- Configuring Falcon prevention and detection policies for different endpoint groups
- Integrating CrowdStrike telemetry with SIEM (Splunk, Elastic, Sentinel) for correlated detection
- Troubleshooting sensor connectivity, performance, or detection issues

**Do not use** this skill for deploying other EDR solutions (Carbon Black, SentinelOne) or for Falcon cloud workload protection (use cloud-specific deployment guides).


## 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

- CrowdStrike Falcon console access with Falcon Administrator role
- Customer ID (CID) and Falcon sensor installer package
- Administrative/root access on target endpoints
- Network access: endpoints must reach CrowdStrike cloud (ts01-b.cloudsink.net on port 443)
- Deployment tool: SCCM, Intune, GPO, Ansible, or manual installation

## Workflow

```python
# 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. **Define Objectives** — Clarify the goals and scope for edr agent.
2. **Gather Resources** — Collect tools, data, and access needed for edr agent.
3. **Execute Process** — Carry out edr agent operations methodically.
4. **Verify Quality** — Check results against acceptance criteria.
5. **Document Outcomes** — Record findings, decisions, and next steps.

## Tools

- **crowdstrike** — 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
1. **Implement** — Write code following existing conventions, add tests
1. **Verify** — Run tests, check integration, validate behavior

## Verification

- [ ] All edr agent 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

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
