# Standards & References - Deploying EDR Agent with CrowdStrike
## Primary Standards
### MITRE ATT&CK Enterprise Framework
- **Publisher**: MITRE Corporation
- **URL**: https://attack.mitre.org/
- **Relevance**: CrowdStrike Falcon maps detections to ATT&CK techniques; understanding ATT&CK is essential for tuning detection policies
- **Key tactics for EDR**: Initial Access, Execution, Persistence, Privilege Escalation, Defense Evasion, Lateral Movement
### NIST SP 800-83 Rev 1 - Guide to Malware Incident Prevention and Handling
- **Publisher**: NIST
- **Relevance**: Defines endpoint protection architecture including EDR placement and malware prevention controls
### CIS Control 10 - Malware Defenses
- **Publisher**: Center for Internet Security
- **Relevance**: CIS Controls v8 Control 10 mandates deploying anti-malware with centralized management and automated updates
## CrowdStrike-Specific References
### CrowdStrike Falcon Deployment Guide
- **Scope**: Official deployment procedures for Windows, macOS, Linux sensors
- **Key sections**: Silent install parameters, proxy configuration, sensor grouping tags
- **Access**: Falcon Console → Support → Documentation
### CrowdStrike Falcon API Documentation
- **URL**: https://falcon.crowdstrike.com/documentation/
- **Scope**: OAuth2 authentication, host management, detection management, RTR APIs
- **Key endpoints**: /devices/queries/devices/v1, /detects/queries/detects/v1
### Falcon SIEM Integration Guide
- **Scope**: Event streaming via SIEM Connector, FDR, and direct API
- **Supported SIEMs**: Splunk, Elastic, Microsoft Sentinel, IBM QRadar, ArcSight
## Compliance Mappings
| Framework | Requirement | CrowdStrike Coverage |
|-----------|------------|---------------------|
| PCI DSS 4.0 | 5.2 - Anti-malware on systems | Falcon sensor on all in-scope endpoints |
| HIPAA | 164.308(a)(5)(ii)(B) - Protection from malware | Falcon prevention + detection |
| SOC 2 | CC6.8 - Malicious software prevention | Falcon sensor with prevention policies |
| NIST 800-171 | 3.14.2 - Malicious code protection | Falcon ML + behavioral detection |
| ISO 27001 | A.12.2.1 - Controls against malware | Falcon sensor with automated response |
## Industry Benchmarks
- **MITRE Engenuity ATT&CK Evaluations**: CrowdStrike Falcon regularly achieves high detection scores in Enterprise evaluations
- **Gartner Magic Quadrant for Endpoint Protection**: CrowdStrike positioned as Leader
- **Forrester Wave Endpoint Detection and Response**: CrowdStrike rated Strong Performer/Leader

# Workflows - Deploying EDR Agent with CrowdStrike
## Workflow 1: Enterprise Sensor Rollout
```
[Plan Deployment]
│
├── Obtain Falcon Console access and CID
├── Download sensor installer for each OS
├── Create deployment groups (Workstations, Servers, VDI)
│
▼
[Configure Policies Before Deployment]
│
├── Create prevention policies per group
├── Configure sensor update policies (pinned vs. auto-update)
├── Set sensor grouping tags for auto-assignment
│
▼
[Pilot Deployment (5% of endpoints)]
│
├── Deploy via SCCM/Intune to pilot group
├── Monitor for 1 week: performance impact, false positives
├── Tune exclusions for LOB applications
│
▼
[Validation]
│
├── All pilot hosts show "Online" in Falcon Console
├── Test detection with CsTestDetect
├── No critical application breakage
│
▼
[Production Rollout (phased)]
│
├── Phase 1: Workstations (2 weeks)
├── Phase 2: Standard servers (2 weeks)
├── Phase 3: Critical servers (1 week, change window)
│
▼
[Post-Deployment]
│
├── Enable SIEM integration
├── Configure automated response policies
├── Establish exclusion review cadence (monthly)
└── Train SOC on Falcon Console workflows
```
## Workflow 2: Detection Triage in Falcon Console
```
[New Detection Alert]
│
▼
[Review Detection in Falcon Console]
│
├── Severity: Critical/High/Medium/Low/Informational
├── Tactic & Technique (ATT&CK mapping)
├── Process tree visualization
├── Network connections
│
▼
[Assess: True Positive or False Positive?]
│
├── True Positive ──► [Contain Host via Network Containment]
│ │
│ ▼
│ [Launch RTR session for investigation]
│ │
│ ▼
│ [Collect artifacts, kill malicious processes]
│ │
│ ▼
│ [Remediate and release from containment]
│
└── False Positive ──► [Create exclusion rule]
│
▼
[Document exclusion with justification]
│
▼
[Mark detection as false positive]
```
## Workflow 3: Sensor Troubleshooting
```
[Sensor Issue Reported]
│
▼
[Check Falcon Console Host Status]
│
├── Online ──► [Issue is not connectivity; check policy assignment]
│
└── Offline / RFM ──► [Check network connectivity]
│
├── Can reach ts01-b.cloudsink.net:443?
│ │
│ ├── Yes ──► [Check proxy settings]
│ │ ▼
│ │ [Reconfigure: falconctl -s --apd=false --aph=proxy --app=8080]
│ │
│ └── No ──► [Firewall blocking; add CrowdStrike domains to allowlist]
│
▼
[Check sensor service status]
│
├── Service running ──► [Review sensor logs in C:\Windows\System32\drivers\CrowdStrike\]
│
└── Service stopped ──► [Restart: sc start csagent (Windows) or systemctl start falcon-sensor (Linux)]
```
## Workflow 4: Sensor Version Upgrade
```
[New Sensor Version Available]
│
▼
[Review Release Notes in Falcon Console]
│
▼
[Test on pilot group (N-1 update policy)]
│
├── No issues after 1 week ──► [Move production to N update policy]
│
└── Issues found ──► [Hold on current version, file support ticket]
│
▼
[Pin current version in sensor update policy]
