Is it possible for viruses to infect the router and install an antivirus program on it?
Are you concerned about unauthorized access to your Wi-Fi network? Or that they could spy on what you're doing from a connected device? Sometimes we think having good antivirus software on our computer is enough. But if your router isn't properly protected, your entire network is at risk. Today, I'll explain why this is a problem and what you can do to avoid it, along with easy-to-implement tips.
Routers are considered the first line of defense against all internet threats. Cybercriminals often focus on attacking these devices to subsequently gain access to the entire local network. For this reason, some brands, such as ASUS, TP-Link, and NETGEAR, have integrated antivirus software and various security measures, such as an Intrusion Prevention System (IPS), into their routers to add an additional layer of security.
- Do I need antivirus software on my router?
The short answer is no, you cannot install antivirus software on your router. These devices run on firmware (a more basic type of software) and are not designed to run antivirus software like you would on a computer. However, that doesn't mean they can't be a target for hackers. A misconfigured router can act as a gateway for all your connected devices.
Can routers get viruses? It's very rare, but yes, it is possible for a router to be hacked. This is usually not because it stores data but because it controls traffic entering and leaving the network. If an attacker can manipulate your router's firmware or DNS settings, they could redirect you to fake websites or intercept your communications. One notorious case was the attack on thousands of routers in 2017, when the FBI recommended everyone reboot their routers and update their firmware.
- 12 basic tips to protect your router and local network:
Securing your network isn't just about having a good password. Your router is the gateway to all the connected devices in your home: your phone, your laptop, your cameras, your smart speakers... everything passes through it. If someone gets in, they can see and control more than you can imagine. That's why we've put together this list of 12 important tips for securing your router starting today, even if you're not a tech expert.
- Update your router's firmware: Updates fix security vulnerabilities. Enable automatic updates if your router allows it, or check the manufacturer's website every few months for a new version.
- Change your router's password: Many routers come with default passwords that anyone can find online. Set a strong, unique password to access your router's settings.
- Change your network name (SSID): Avoid using your last name or anything that can be easily guessed. Use a generic name that doesn't give away what type of router you're using or who lives in the house.
- Activate WPA3 or WPA2 encryption: This is what keeps your Wi-Fi network secure. If your router is newer, activate WPA3. If not, make sure you're at least using WPA2-AES.
- Disable features you don't use. For example, remote management or UPnP, which are usually enabled by default. If you don't know what they are for, it's best to disable them.
- Create a guest Wi-Fi network: If someone comes to your home, don't give them the password to your main network. Create a separate network for guests or less secure devices.
- Set up a good firewall: Many routers include a firewall, but sometimes it's disabled. Go to Settings and make sure the firewall is enabled.
- Restrict external access: Close unused ports and disable features such as access from outside the network. The less visible your network is from the outside, the better.
- Enable two-factor authentication (if available): Some modern routers allow you to use an additional app or code when logging into the settings. This is an additional layer of security that is highly recommended.
- Don't use easy or repetitive passwords. Avoid words like "123456" or "password." Use long passwords that contain numbers, letters, and symbols. If you have difficulty remembering them, use a password manager.
- Monitor connected devices: Log in to your router's dashboard from time to time and check the connected devices. If you see a password you don't recognize, change it immediately.
Consider upgrading your router if it's too old: If your router hasn't been updated in years or doesn't support WPA2 or WPA3, it's time to upgrade to a more modern and secure one.
You don't need to be an expert to improve your network security. With these tips, you can close many of the doors that cybercriminals often exploit. Your router is the guardian of your connection. Take care of it, update it, and protect it well, and the rest of your devices will be more secure, too.
