How to protect your home Wi-Fi?

There are several ways of illegal intrusion into the house. For example, in one case an intruder breaks into the door, and in another – penetrates your computer. And if he was able to gain control over your wireless network Wi-Fi, it may already got the keys to the main entrance. Certainly, Wi-Fi networks provide easy access to your data, which is stored in a global network, eliminating the need to connect using wires. However, at the same time incorrectly configured WLAN wireless LAN provides the same access and the attacker. There are a few simple steps by doing that, you can be sure – your network is protected as much as possible. On their readers AIF.RU told Anton Razumov, head of security consultants company Check Point Software Technologies.

Step 1: Avoid default passwords

If you configure the router you leave the password for the default administrator, from a technical point of view you are doing very imprudent. You should also change the default password for the guest account, of course, if you include it. If you have already done so, you need to come up with a strong password that will be used instead of the old. The Internet already published many materials about creating complex passwords. But if you need just a couple of tips to start with the letters and numbers mixed up, so that your password has not been a word from the dictionary. Do not use birthdays, names of relatives, pet names or other phrases that are easy to guess.

Step 2: Think about changing the default network name (SSID)

The SSID is the public name of your wireless network. In most cases, manufacturers use the same SSID names for all of their products lines. Although this option does not directly affect the security of the network, it’s worth it to change the name. The fact that an attacker can attack the network with the default name, suggesting that the network parameters are set as default passwords, and security of the router is not configured. However, despite the controversy about hiding SSID, in fact, this method does not have much impact on safety. Yet SSID – this is not the password for the network, and there are many tools with which a hacker can find it.

Step 3: Protect your access point using encryption

Just need to use encryption to protect your wireless network. The best option for home use is WPA2 (WiFi Protected Access 2), the algorithm applies a stronger encryption than previous technologies, such as WPA and WEP (Wired Equivalent Privacy), the protocol, which appeared before the WPA and found a huge number of gaps in protection. Unlike other versions, WPA2 requires algorithms AES (Advanced Encryption Standard). If you choose WPA2, will need to create a key to connect users to the network. It is important to verify that the password is unique and complicated to others could not guess or hack it. Make sure that your chosen number of characters long enough and consists of numbers and figures. If your key is weak, it will not be difficult for hackers to crack your network.

However, WPA2 is not supported by some older wireless adapters, so we recommend that you use the most reliable means of encryption available for your equipment. Do not include WPS (WiFi Protected Setup). It does not always work consistently, and his nine-digit password vulnerable to a break-in attempts. Once an attacker finds out the PIN for WPS, for it immediately disappear barriers to access data that resides in your wireless network.

Step 4: Enable filtering by MAC-address

In management software has a list of devices that shows the names of all computers connected to Wi-Fi. Sometimes it is recommended to check the list. And in order to prevent unknown users connect to your network, you can use filtering by MAC-address.

Address Device Control (MAC) is a unique identifier of your computer. Including filtering by MAC-addresses, you can maintain control over who can connect to your network and who is not. After enabling this option the router / access point will check the MAC-address of each client sends a request to connect to the network, and compare it the predefined list. And those numbers are not contained in your list can not connect. Of course, this solution can not completely isolate your network from fraud, because MAC-address can be falsified. So make sure that the other security measures were also taken.

Step 5: Disable remote administration

Some wireless routers allow an administrator to remotely manage the configuration of the device from anywhere. And if you have no need for this, do not leave this feature enabled. The fact that it creates an auxiliary input, which can take advantage scammer to get administrator rights on your router directly via the Internet.

Remember, even steel doors from no protection if you leave them open, and we recommend that you follow these simple steps to protect themselves from hacking.
