TIPS, AND INSIGHTS TO HELP NAVIGATE THE DIGITAL WORLD SECURELY IV - HOW TO SECURE YOUR HOME NETWORK LIKE A PRO: A Comprehensive Guide

In our previous article (Essential Cybersecurity Tips for Beginners)¹ we have learned how understanding the basics of cybersecurity can help protect your personal information, financial assets, and digital identity.

With the rise of smart devices, remote work, and online entertainment, your home network is a gateway to both convenience and vulnerability. Cybercriminals are constantly looking for weak points to exploit, from unsecured routers to poorly protected IoT devices.

In this article will walk you through advanced strategies to secure your home network like a pro, ensuring your data, privacy, and devices remain safe. Additionally, we’ll explore how PT SYDECO’s ARCHANGEL 2.0, a Next-Generation Firewall (NGFW) with advanced features like VPN hosting and micro-segmentation, can elevate your home network security to enterprise-grade levels.

1. Setting Up Strong Router Security

Your router is the backbone of your home network. If it’s not secure, everything connected to it is at risk. Here’s how to fortify your router:

a. Change Default Credentials

• Why it matters: Default usernames and passwords for routers are often publicly available, making them easy targets for hackers.
• What to do: Log into your router’s admin panel (usually accessible via a web browser at 192.168.1.1 or a similar address) and change the default username and password to something strong and unique. 

b. Enable WPA3 Encryption

• Why it matters: Wi-Fi encryption protects your network traffic from being intercepted. WPA3 is the latest and most secure encryption standard.
• What to do: Access your router’s settings, navigate to the wireless security section, and select WPA3 encryption. If your router doesn’t support WPA3, use WPA2 as a fallback. 

c. Set Up a Firewall

• Why it matters: A firewall acts as a barrier between your network and potential threats from the internet.
• What to do: Most modern routers come with a built-in firewall. Ensure it’s enabled in your router’s settings. For advanced protection, consider integrating PT SYDECO’s ARCHANGEL 2.0, a Next-Generation Firewall (NGFW) that provides enterprise-grade security features, including deep packet inspection, intrusion prevention, and real-time threat detection. 

d. Disable WPS (Wi-Fi Protected Setup)

• Why it matters: WPS is a convenience feature that allows easy device connections, but it’s notoriously vulnerable to brute-force attacks.
• What to do: Turn off WPS in your router’s settings. 

e. Update Router Firmware Regularly

• Why it matters: Router manufacturers release firmware updates to patch vulnerabilities and improve security.
• What to do: Check for updates in your router’s admin panel or enable automatic updates if available.

  

2. Segmenting IoT Devices for Added Security

The Internet of Things (IoT) has brought smart devices into our homes, but many of these devices lack robust security features. Segmenting your network can prevent a compromised IoT device from affecting your entire network.

a. Create a Separate Network for IoT Devices

• Why it matters: Isolating IoT devices from your main network limits the damage if one is hacked.
• What to do: Use your router’s guest network feature or VLAN (Virtual Local Area Network) capabilities to create a separate network for IoT devices. Ensure this network has its own password and encryption. 

b. Use Micro-Segmentation with ARCHANGEL 2.0

• Why it matters: Micro-segmentation goes beyond basic network segmentation by creating isolated zones for individual devices or groups of devices. This ensures that even if one device is compromised, the threat cannot spread.
• What to do: Implement PT SYDECO’s ARCHANGEL 2.0, which supports micro-segmentation to create highly secure, isolated environments for your IoT devices, workstations, and critical systems. 

c. Monitor IoT Device Activity

• Why it matters: Unusual activity on an IoT device could indicate a security breach.
• What to do: Use network monitoring tools to keep an eye on traffic from IoT devices. ARCHANGEL 2.0 includes advanced monitoring and analytics features to help you detect and respond to threats in real time.

 

3. Enabling Two-Factor Authentication (2FA) for Critical Accounts

Two-factor authentication (2FA) adds an extra layer of security to your online accounts by requiring a second form of verification in addition to your password.

a. Enable 2FA on Your Router

• Why it matters: If someone gains access to your router’s admin panel, they can wreak havoc on your network.
• What to do: If your router supports 2FA, enable it in the security settings. This typically involves linking your router to an authentication app like Google Authenticator or Authy. 

b. Use 2FA for All Critical Accounts

• Why it matters: Passwords alone are no longer enough to protect your accounts. 2FA significantly reduces the risk of unauthorized access.
• What to do: Enable 2FA on all accounts that support it, especially email, banking, and social media accounts. Use an authentication app or hardware security keys for added security.

c. Avoid SMS-Based 2FA When Possible

• Why it matters: SMS-based 2FA is vulnerable to SIM swapping attacks.
• What to do: Opt for app-based or hardware-based 2FA methods whenever possible.

 

4. Additional Pro Tips for Home Network Security

a. Use a VPN (Virtual Private Network)

• Why it matters: A VPN encrypts your internet traffic, making it harder for hackers to intercept your data.
• What to do: Install a reputable VPN on your router or individual devices, especially when accessing public Wi-Fi. PT SYDECO’s ARCHANGEL 2.0 includes a built-in VPN server, allowing you to securely access your home network from anywhere in the world.

b. Disable Remote Management

• Why it matters: Remote management allows you to access your router’s settings from outside your home network, but it also opens a potential entry point for attackers.
• What to do: Disable remote management in your router’s settings unless absolutely necessary. 

c. Regularly Audit Connected Devices

• Why it matters: Unauthorized devices on your network could be a sign of a breach.
• What to do: Periodically review the list of connected devices in your router’s admin panel and remove any unfamiliar ones. ARCHANGEL 2.0’s advanced monitoring tools can help you identify and manage connected devices with ease. 

d. Use Strong, Unique Passwords

• Why it matters: Weak or reused passwords are a common cause of security breaches.
• What to do: Use a password manager to generate and store strong, unique passwords for all your accounts and devices. 

e. Educate Your Household

• Why it matters: Even the most secure network can be compromised by human error.
• What to do: Teach everyone in your household about basic cybersecurity practices, such as recognizing phishing attempts and avoiding suspicious links.
