WiFi is very common to see in any house. These are used to connect to the Internet Wirelessly. Previously we use cables to do the same. WiFi is very common so having a secure WiFi Network at home is essential. Security to these networks ensures the security of our personal data. If these Wifi networks are unsecured then they can cause harm to us. Hence, some Wifi Security Best practices will help us out. These practices ensure the security of our WiFi networks.

Some WiFi Security Standards

1. WEP (Wired Equivalent Privacy)

WEP has been developed in September 1999. It was supposed to give the same security as that of Wired ones. But the reality is different. There are many issues in WEP. These issues can be easily compromised to break into.

Many improvements are done on WEP. But nothing works well. It is still easy to break. Networks that use WEP need to upgrade to latest security. WEP Wifi Security was officially abandoned by the Wi-Fi Alliance in 2004. Using WEP will not be beneficial. Consequently risking security. Thus, nowadays it's obsolete.

2. WPA WiFi Protected Access

When 802.11 WiFi standard came. WPA is used over WEP on a temporary basis. When WEP has been discarded WPA was formally used. Most Modern WPA uses a Pre Shared Key (PSK) to enhance Wifi Security. It uses Temporal Key Integrity Protocol or TKIP for encryption.

WPA has been upgraded over WEP. After many improvements, it still has some flaws. These flaws are related to WiFi Protected Setup (WPS). WPS is developed to ease the linking process of the devices.

3. WPA 2 WiFi Protected Access V2

The 802.11i wireless security standard based protocol was introduced in 2004. WPA2 has many improvements over WPA. The most important one is the Advanced Encryption Standard (AES). AES is approved by the U.S. government for encrypting the information. Hence, this can be used for Homes to Secure WiFi Network. Using WPA2 is one of the WiFi Security Best Practices.

Apart from many improvements. WPA 2 still has some flaws. These flaws can be used to compromise a network.
