The security of wireless networks is essential for a business to improve security and the success of business.

Frémont, California: Wireless networks are developing more and more in businesses, and with increasing threats to wireless networks, wireless security ensures that unauthorized access to wireless networks is limited. Various factors could contribute to the increase in attacks on wireless networks. Unlike wired networks, where an attacker must physically access the network, a wireless network simply requires the attacker to be nearby. As a result, the growth of attacks is due to the nature of wireless networks to allow easy access to end users.

Nothing can replace a safe, secure and reliable WLAN to provide maximum security and keep the business running smoothly. Here are seven solid recommendations for improving wireless network security.

  1. Always stay alert- Never assume that hackers aren’t interested in a business. While an employee might not be the person they are targeting, they can act as an intermediary to a hacker’s target.
  2. The equipment must meet WLAN standards. It is essential to examine whether new WLAN equipment meets the appropriate wireless network standards before purchasing it. It is best to order all types of equipment from the same manufacturer to avoid future compatibility difficulties.
  3. Frequent upgrade of WLAN security protocols Enhance device security from basic WLAN equivalent wired (WEP) privacy. For added security, a business can choose the latest devices with built-in Wi-Fi protected access protocols.
  4. Activate WLAN security functions When installing new equipment, enable security settings such as MAC address restrictions, Wi-Fi encryption, and broadcast SSID. If an organization is not sure, it should check and recheck because any errors can expose the entire network to attack.
  5. Provide physical security To prevent radio signal leakage, locate data transfer equipment away from the exterior wall of the building. This eliminates the possibility of outside interception.
  6. Allow access only to authorized users- In the majority of cases, all employees have access to Wi-Fi. However, employees must obtain permission from management to install access points. Workers should exercise extreme caution as a single vulnerable access point can put the entire network at risk.
  7. Using VPN- To protect transferred data, use the latest technology and encryption such as SSL communication protocols or a virtual private network (VPN). It would be prudent to use firewalls to separate the WLAN from the rest of the network.
