NSA-Recommended Tips to Keep Your Home Network Secure
In today’s hyper-connected world, securing your home network is no longer optional. With more people working remotely, streaming content, and using smart devices, your home Wi-Fi has become a prime target for cybercriminals.
The National Security Agency (NSA) has issued guidance on how individuals can better protect their home networks from digital threats. These best practices are simple but powerful — and they can help prevent data breaches that put both personal and business information at risk.
In fact, nearly half of all businesses reported at least one cybersecurity incident within two months of shifting to remote work. That shows just how vulnerable home networks can be.
Let’s walk through the NSA’s top recommendations for keeping your home network secure.
1. Change Default Logins Immediately
Most routers and smart devices come with pre-set usernames and passwords — many of which are widely known among hackers.
Fix this: As soon as you set up a new device, change the default login credentials to something strong and unique.
2. Enable Strong Wi-Fi Encryption
Encryption scrambles your data so only authorized users can read it. Without it, anyone nearby could potentially intercept your traffic.
Use WPA3 encryption if your router supports Wi-Fi 6. If not, go with WPA2 , which is still secure if configured properly.
3. Keep Firmware Updated
Your router’s firmware is like the operating system of your network. Manufacturers release updates to fix security flaws and improve performance.
Tip: Set a monthly reminder to check your router’s settings or manufacturer website for available firmware updates.
4. Turn On the Built-In Firewall
Most modern routers include a firewall — a critical tool that blocks unauthorized access and filters harmful traffic.
Make sure it’s enabled in your router’s settings. This adds an essential layer of protection between your network and the internet.
5. Disable Unused Features
Routers often come with features like remote management, file sharing, or media streaming enabled by default.
If you don’t use them, turn them off . Every extra service increases your attack surface and gives hackers more ways to get in.
6. Secure Your Wi-Fi Network
Beyond encryption, there are several steps you can take to harden your wireless network:
- Rename your SSID (network name) – Avoid using your name, address, or anything identifying.
- Hide your SSID – Prevent your network from broadcasting publicly.
- Enable MAC address filtering – Allow only trusted devices to connect.
- Disable WPS – Wi-Fi Protected Setup is known to have vulnerabilities.
7. Use Strong, Unique Passwords
Weak passwords are one of the easiest ways for attackers to gain access. Make sure:
- Your Wi-Fi password is at least 12 characters long
- It includes a mix of uppercase, lowercase, numbers, and symbols
- You avoid reusing passwords across accounts
Consider using a password manager to generate and store complex passwords securely.
8. Create a Separate Guest Network
Friends or kids’ friends may need internet access — but they shouldn’t have full access to your main network.
Set up a guest Wi-Fi network instead. It keeps your primary network isolated and protected while still offering connectivity to visitors.
9. Limit Physical Access
Anyone with physical access to your router could potentially reset it or tamper with its settings.
Place your router in a secure location — like a locked cabinet or a room with limited access. Also, disable physical configuration tools unless needed.
Final Thoughts: Don’t Wait Until It’s Too Late
Your home network is the gateway to your digital life — from personal photos to banking details and even company data if you’re working remotely.
By following these NSA-recommended best practices, you can dramatically reduce your risk of falling victim to a cyberattack.
