# IoT Security Protocols
This playbook outlines the necessary steps to secure Internet of Things (IoT) devices and the networks they are connected to. It focuses on establishing a robust security protocol to protect against potential threats and vulnerabilities inherent in IoT ecosystems.

### Step 1: Device Inventory
Create a comprehensive inventory of all IoT devices connected to the network. Include details like device type, location, function, and connectivity method.

### Step 2: Update Firmware
Ensure that all IoT devices are running the latest firmware version available from the manufacturer to patch known vulnerabilities.

### Step 3: Secure Configuration
Configure each IoT device with secure settings, disabling unnecessary features, and enforcing strong, unique passwords for device access.

### Step 4: Network Segmentation
Implement network segmentation to isolate IoT devices from other critical network segments, reducing the risk of lateral movement in case of compromise.

### Step 5: Encryption
Apply strong encryption to data at rest and in transit, protecting sensitive information from eavesdropping and man-in-the-middle attacks.

### Step 6: Access Control
Establish strict access control policies, limiting device access to authorized users, systems, and other IoT devices.

### Step 7: Monitoring
Set up continuous monitoring of IoT devices for unusual activities, which could indicate a security breach or other issues.

### Step 8: Incident Response
Develop an incident response plan tailored for IoT environments to quickly address any security incidents that arise.

### Step 9: Security Education
Educate all stakeholders on IoT security best practices and the importance of keeping their devices and the networks secure.

## General Notes

### Vendor Risks
Consider the security policies and incident response capabilities of IoT device manufacturers when selecting products.

### Updates Policy
Create a policy for regularly scheduled updates and patches to maintain security across your IoT infrastructure.

### Legal Compliance
Ensure compliance with all local laws and regulations concerning IoT device operation and data security to avoid legal liabilities.
