To accommodate working from home and, now with schools starting, remote learning, both parents and students will use various devices that require an internet connection. These devices will likely use a home wireless (Wi-Fi) network; however, the Wi-Fi router may not be set up securely. If a Wi-Fi network is left unsecured, a threat actor could potentially gain unauthorized access to the network and the devices connected to it. As a result, personal, financial, and otherwise sensitive data could be exposed, and their access may lead to other types of malicious activity. Below are some recommendations to help protect your network, data, and devices from unauthorized access and other malicious activity.
- Change the router default username and password. Default router credentials are often publicly available and can be used to gain unauthorized access to your network. Pro Tip: The same is true for any Internet of Things (IoT) connected device, such as security camera, doorbell, refrigerator, etc.
- Change the network name (SSID). Default SSIDs may give away the router’s model, which could provide threat actors information necessary to obtain the router password (if using default credentials) or determine potential vulnerabilities that could be exploited.
- Enable WPA2 with AES (or WPA3, if available). Wi-Fi Protected Access versions 2 and 3 (WPA2/WPA3) are both recommended options for ensuring data on devices connected to the network is properly encrypted and secured.
- Update your router’s firmware. Unlike software that provides automatic updates or prompts users to install updates, Wi-Fi router firmware needs to be manually downloaded and installed. Without firmware updates, routers may contain known vulnerabilities or use outdated encryption that could compromise the security of the network.
- Create separate networks for devices. Creating separate Wi-Fi networks for groups of devices with similar purposes and/or sensitivity can help to prevent an entire network of devices from being compromised if a threat actor is able to gain unauthorized access to one device or network. For example, keep IoT devices on one network and mobile devices on another.
- Place the router in the center of your home. This placement provides the best coverage for the devices in your home, while also making it less likely that the signal will be strong enough for someone outside your home to connect to your network.
A little bit of time spent reconfiguring your router will go a long in helping secure your home network, and as a side benefit, help increase overall wireless performance. If you have any questions related to the above WiFi tips, please visit us at powersolution.com or give us a call at 201-493-1414
