With the introduction of 802.11n and Mesh technologies, Wireless Local Area Network (WLAN), as an emerging Internet broadband access method, is gradually changing people's traditional way of surfing the Internet based on fixed broadband. Get rid of the shackles of network cables, people can connect to the Internet through portable terminal devices such as laptops, netbooks, smartphones, etc., in any place where a wireless local area network is deployed, such as libraries, shopping malls, cafes, restaurants and other public places and office buildings. and other office spaces, which greatly meets the urgent needs of users who need to access the Internet anytime, anywhere. The application of the centralized WLAN architecture greatly reduces costs and simplifies tasks such as wireless system management, security, and upgrades, resulting in rapid popularization and rapid development of WLANs.
Wireless local area network adopts wireless channel as the information transmission channel between terminal and access point (Access Piont), which is more open and convenient than traditional fixed line, but also brings new challenges to network security. The original fixed LAN network security technologies, strategies and management methods can no longer meet the needs of network security under the new situation of wireless LAN. Especially for enterprises with high demands on network security, how to effectively prevent illegal access from the outside world and protect sensitive information while using WLAN to improve office conditions is the focus of current enterprises.
While some standards, such as Wi-Fi WPA2 and 802.11i, offer a whole new level of wireless security capabilities and are supported by new monitoring and intrusion prevention tools, the focus of enterprises has shifted to how to combine traditional network security with physical security. Combined, a new network security solution based on location information is formed. Helps businesses balance the need to provide the necessary checks on this unmanageable freedom while providing mobile Internet access for their own employees and visitors.
For example, an enterprise deploys a wireless local area network in its own office building to facilitate employees to work, but the enterprise does not want people outside the office building to access its own wireless local area network to prevent security risks such as network attacks and sensitive information theft. For another example, an enterprise needs to implement wireless Internet access for the human resources department because of office work, but it needs to restrict wireless access except for the human resources department to prevent others from accessing sensitive data within the department, such as employee information and performance appraisal information.
This is where location-based security technology comes into play: restricting WLAN access based on the user's location. In addition to adding a layer of physical security, location control plus access control can prevent overloading of network elements (and prevent "denial of service" attacks), as well as restrict where guests can access the network.
