# Security Guidlines

### **🔹 Authentication & Access Control**

To ensure security, all API requests must use one of the following authentication methods:

* **API Keys:** Secure and unique keys assigned to each user.
* **OAuth2 Tokens:** Enterprise authentication for large-scale clients.
* **JWT Tokens:** Secure session-based authentication.

For additional security, API keys can be **restricted by IP address** and **assigned granular permissions**.

**API Key Authentication**

```http
GET /facts
Authorization: Bearer YOUR_API_KEY
```

### **🔹 Encryption Standards**

All API requests and responses are secured using the latest encryption protocols:

✔ **TLS 1.3 encryption** for all communication.\
✔ **AES-256 encryption** for stored intelligence data.\
✔ **HMAC-SHA256 signing** for verifying API responses.

This ensures that data is protected from interception, tampering, and unauthorized access.

### **🔹 Secure API Key Management**

To protect your API key:

* **Never hardcode your API key** in source code.
* Store it in **environment variables** or **secure vaults**.
* **Rotate API keys** regularly to minimize security risks.
* **Restrict API access** by setting IP-based restrictions.

### **🔹 OAuth2 Authentication (Enterprise Clients Only)**

OAuth2 provides secure token-based authentication for enterprise clients.

#### **Step 1: Obtain an Access Token**

Make a request to retrieve an access token.

**OAuth2 Authentication Request**

```http
POST /oauth/token
Content-Type: application/json  

{
  "client_id": "your_client_id",
  "client_secret": "your_client_secret",
  "grant_type": "client_credentials"
}
```

**Using the OAuth2 Access Token**

```http
GET /facts
Authorization: Bearer ACCESS_TOKEN
```

### **🔹 JWT Token Authentication**

JSON Web Tokens (JWT) allow secure, stateless authentication.

To generate a JWT token, sign the request with your private key.

**JWT Token Authentication**

```http
Authorization: Bearer YOUR_JWT_TOKEN
```

### **🔹 API Rate Limits & Throttling**

To prevent abuse, the API enforces rate limits based on user tiers:

| Plan       | Requests per Minute | Requests per Day |
| ---------- | ------------------- | ---------------- |
| Free       | 10                  | 1,000            |
| Pro        | 100                 | 50,000           |
| Enterprise | Unlimited           | Unlimited        |

If rate limits are exceeded, API requests will return a **429 Too Many Requests** error.

### **🔹 Data Integrity & Verification**

All intelligence data is **cryptographically signed** to ensure authenticity. AI-driven verification eliminates misinformation by cross-referencing multiple sources.

✔ **Immutable Storage:** Data cannot be altered once recorded.\
✔ **AI Fact-Checking:** Ensures accuracy and removes false information.\
✔ **Source Transparency:** Intelligence reports include metadata for validation.

**Securing API Keys in Environment Variables (Python)**

```python
import os

API_KEY = os.getenv("TRUTH_SATELLITE_API_KEY")
```

### **🔹 Incident Response & Monitoring**

The system continuously monitors API access for anomalies. If unauthorized activity is detected:

✔ **Automatic API key revocation** for compromised accounts.\
✔ **Real-time anomaly detection** using AI-based monitoring.\
✔ **24/7 Security alerts** for all enterprise clients.

**API Rate Limit Response**

```json
{
  "error": "Too Many Requests",
  "code": 429,
  "message": "Rate limit exceeded. Please wait before making new requests."
}
```

If you suspect unauthorized access, immediately contact **<security@truthsatellite.space>**.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://truth-satellite.gitbook.io/truth-satellite/docs/security-guidlines.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
