+### Expanded Focus: Device-Based Firewall Profiles
+
+#### Aim and Scope
+
+The central aim is to develop a standardized architecture for secure device-based firewall profiles. This involves:
+
+- **Creating a Standard for Firewall Profiles**: Defining a universal format and structure for firewall profiles that routers and firewall systems can easily understand and implement.
+- **Facilitating Automated Configuration**: Enabling home and corporate routers to automatically interpret and apply these profiles, enhancing network security and reducing setup complexity.
+- **Improving Device Security**: By standardizing firewall profiles, the goal is to reduce the attack surface of devices and lower the chances of vulnerabilities being exploited.
+
+#### Proposed Structure
+
+1. **General Structure**:
+
+   ```plaintext
+   /.well-known/device-instructions
+       /{manufacturer}
+           /security-contact.json       # Manufacturer security contact information
+           /{device-model}
+               /firewall-profile.json   # Firewall profile for the device
+               /security-contact.json   # Security contact information
+   ```
+
+   - Each device model has a `firewall-profile.json` detailing the suggested firewall settings and rules for that specific device.
+   - The `security-contact.json` remains a supportive feature for reporting security concerns.
+
+2. **Firewall Profile Content**:
+   - **Profile Definition**: `firewall-profile.json` contains the necessary firewall rules and settings tailored for the device.
+   - **Format and Standards**: The profile should be in a standardized format (like JSON) that is easy for routers and firewalls to parse and implement.
+   - **Documentation**: Include comments or explanations within the profile to clarify the purpose and necessity of each rule.
+
+3. **Response Time Specification** (for `security-contact.json`):
+   - A section in `security-contact.json` to specify the expected response time for inquiries, maintaining a clear communication channel for security issues.
+
+#### Expanded Goals
+
+- **Ease of Implementation**: Ensure that the firewall profile structure is straightforward to implement by device manufacturers and easily interpretable by router and firewall systems.
+- **Interoperability**: Design the profiles universally applicable across different network environments and router models.
+- **Dynamic Updating**: Consider mechanisms for updating firewall profiles as device firmware and threat landscapes evolve.
+- **Security Reporting**: While not the primary focus, maintain an efficient and straightforward mechanism for reporting security issues, complementing the overall security architecture.
+
+#### Additional Considerations
+
+- **Testing and Validation**: Encourage thorough testing of the firewall profiles in various network scenarios to ensure effectiveness and compatibility.
+- **Community and Industry Feedback**: Engage with the broader tech community, including security experts and network administrators, for feedback and suggestions.
