How to Secure Your Wireless Network? Wireless networks allow people to be more flexible in their time. Wireless has made it possible to be more flexible thanks to its invention. Wireless will enable people to work remotely while caring for their children or performing housework. Traffic jams cause no more stress. This is amazing!
There is something that you need to realize. If you don’t take proper precautions, working from home and using a wireless network can lead to hacker or virus intrusion, as well as the theft of sensitive information. Wireless local area networks (WLANs) transmit data via radio waves. Someone could pick up this transmission and gain access to your computer. You could allow them to install viruses onto your computer, which could then be transmitted to the company’s network.
It’s true! Approximately 75% of WLAN users don’t have security features, and 20% are left open. The default configurations, which aren’t designed to protect users’ networks, allow them to get their network running as quickly as possible. It is strongly recommended that access point/wireless router setups be made using a wired client.
These steps will help you set up your security:
1. Change the default password for the access point/wireless router to a secure password
2. Enable WEP encryption at least 128 bits on both the card and access point. Your WEP keys should be changed regularly. Consider replacing equipment that does not support WEP encryption at 128 bits. While WEP encryption has its security flaws, it is the minimum level of security and should be enabled.
3. You can change the default SSID of your router/access point to a problematic guess the name. This SSID will be used to establish a connection to your computer.
4. The SSID should not be broadcast by the router/access point. On the client-side, the same SSID must be set up manually. This feature might not be available for all equipment.
5. You can block anonymous Internet requests and pings. Each computer with a wireless network card should have network connection properties that allow access to Access Point Networks only. It is not permitted to connect computer to computer (peer-to-peer)
Allow MAC filtering. For unspecified MAC addresses, deny wireless network association. Your computer network connection setup will provide Mac and Physical addresses. These physical addresses are written on network cards. The router/access point should have their MAC addresses registered when adding wireless cards/computers to the network. The firewall feature should be enabled on the router, and the demilitarized zone(DMZ) feature disabled.
Every computer should have a personal firewall that is properly configured, as well as a physical firewall. When new versions are available, you should also upgrade router/access points firmware. It is crucial to locate router/access points away from strangers so that they can’t reset them to their default settings. To limit signal coverage outside of your building, you can locate the router/access point in a central location.
Although there is no way to protect your wireless network completely, these tips will help reduce the risk of being exposed to hackers looking for insecure networks.
