Article Two – Home Cybersecurity Series
Creating a comprehensive inventory of your home network is essential for effective home cybersecurity. Understanding the devices connected to your network allows you to manage potential vulnerabilities effectively. In this guide, we’ll walk you through the steps to assess your home network inventory, ensuring a more secure digital environment.
How to Start Your Home Network Inventory
Begin by examining your router, likely provided by your Internet Service Provider (ISP). Take note of its make, model, and any other crucial details, including whether the default password has been changed.
Your home network may also include a switch to accommodate more devices. Record the make and model information from this device as well.
If you utilize a secondary Wi-Fi router, be sure to gather similar information from it.
Next, walk through your home and identify all connected devices, including smart light bulbs, thermostats, and other IoT gadgets. Don’t overlook uninterruptible power supplies (UPS) and switches.
Gathering Detailed Device Information
When assessing computers, tablets, and smartphones, you need more than just their make and model. Here’s how to extract detailed information:
For Windows PCs:
- Press Windows+R
- Type msinfo32 and hit Enter
- In the “System Summary,” select File > Export
- Name the file and save it to a desired location.
For Macs:
- Click Apple menu > System Settings > General
- Select About
- Choose System Report
- Save the report to your desired location.
For Android Devices:
- Open Settings > About phone
- Document CPU, RAM, and display details.
For iPhones/iPads:
- Navigate to Settings > General > About
- Write down the device specifications.
After gathering all necessary information, compile it into a spreadsheet for future reference.
Performing a Network Scan
Once you have a written inventory, the next step involves scanning your home network digitally. This includes both wired (Ethernet) and wireless connections.
Numerous tools, such as IP Scanner and Fing, provide user-friendly options. Advanced tools like Nmap and Wireshark offer deeper insights.
To access your router’s settings, enter its IP address, usually either 192.168.1.x or 192.168.0.x, in your web browser. By logging in, you can access your router’s device list, which reveals all connected devices on your home network.
Understanding IP Addresses and Next Steps
Keep in mind that IP addresses can change due to DHCP (Dynamic Host Configuration Protocol). This system dynamically assigns IP addresses, meaning some devices might have different addresses in the future.
With your devices cataloged, the next step is to assess your setup for security and privacy. Use the gathered information to create a security plan tailored to your unique home network needs.
In the next article, we will explore how to diagram your home network, enhancing security and minimizing vulnerabilities.
Devices to Consider:
- A robust hardware firewall to prevent unauthorized access.
- A smart switch for efficient traffic management between devices.
