# Implementing Email Sandboxing with Proofpoint


## Genel Bakış
Email sandboxing detonates suspicious attachments and URLs in isolated environments to tespit etme
zero-day malware and evasive phishing payloads. Proofpoint Targeted Attack Protection (TAP) is an industry-leading solution that uses multi-stage sandboxing, URL rewriting, and predictive analysis. bu skill covers configuring Proofpoint TAP, integrating with email flow, analyzing sandbox reports, and tuning Tespit policies.


## Ne Zaman Kullanılır

- Dağıt:ing yaparken or configuring implementing email sandboxing with proofpoint capabilities in your environment
- establishing yaparken: security controls aligned to compliance requirements
- building yaparken or improving security architecture for this domain
- conducting yaparken security assessments that require this implementation

## Ön Gereksinimler
- Proofpoint Email Protection license with TAP add-on
- Admin Erişim: Proofpoint admin console
- Understanding of email delivery architecture (MX records, mail flow rules)
- SIEM integration capability

## Key Concepts

### Proofpoint TAP Capabilities
1. **Attachment sandboxing**: Detonates files in virtual machines (Windows, macOS, Android)
2. **URL Defense**: Rewrites URLs, detonates at time-of-click
3. **Threat Intelligence**: Proofpoint's NexusAI threat intelligence integration
4. **TAP Dashboard**: Real-time visibility into threats targeting the organization
5. **Campaign correlation**: Groups related attacks into campaigns
6. **Very Attacked People (VAP)**: Identifies most-targeted individuals

### Sandbox Evasion Techniques Detected
- Delayed execution (time-bomb malware)
- VM Tespit bypass
- User interaction requirements (click-to-enable macros)
- Sandbox-aware malware that checks for analysis environment
- Encrypted/password-protected attachments
- Multi-stage payloads with delayed C2 retrieval

## İş Akışı

### Adım 1: Configure TAP in Proofpoint
- Enable TAP for inbound email policy
- Configure sandbox profiles (attachment types to detonate)
- Set URL Defense rewriting policy
- Configure quarantine actions for malicious verdicts

### Adım 2: Tune Attachment Policies
```
Recommended attachment policy:
- Detonate: .exe, .dll, .scr, .doc(m), .xls(m), .ppt(m), .pdf, .zip, .rar, .7z, .iso
- Block without detonation: .bat, .cmd, .ps1, .vbs, .js, .wsf, .hta
- Password-protected archives: Attempt common passwords, then quarantine
- Dynamic delivery: Deliver email body, hold attachment until verdict
```

### Adım 3: Configure URL Defense
- Enable URL rewriting for all inbound email
- Set time-of-click detonation
- Block Erişim: malicious URLs
- Show warning page for suspicious (not confirmed malicious) URLs
- Configure allowed domains bypass list

### Adım 4: Kur: TAP Dashboard Monitoring
- Configure daily threat digest emails to security team
- Kur: real-time alerts for targeted attacks
- Monitor VAP report for high-risk users
- Review campaign clusters for coordinated attacks

### Adım 5: Integrate with SIEM
- Configure syslog/API export to SIEM
- Create correlation rules for TAP alerts
- Kur: automated response workflows
