ccna 9.2.1.4.In the early 21st century, the Autonomous AP deployment model was quickly replaced by the Lightweight AP deployment model. Lightweight APs rely on a WLAN controller (WLC) for configuration. This is different from autonomous APs, which require individual configuration for each device. The Lightweight AP wireless controller solution offers several benefits not previously available, such as fraud AP detection and location.CiscoWLC is responsible for system-wide wireless LAN functions such as security policy, intrusion prevention, RF management, QoS, and mobility. These functions work in concert with APs and CiscoWLC to support wireless applications. From voice and data services to location tracking, CiscoWLC provides the control, scalability, security, and reliability to build secure, enterprise-class wireless networks from the branch office to the main campus.CiscoWLCs integrate smoothly into existing enterprise networks. They use Lightweight AP Protocol (LWAPP) to communicate with lightweight APs on Layer 2 or Layer 3 infrastructure. These devices support automation of multiple WLAN configuration and management functions from anywhere in the enterprise.Because CiscoWLC supports IEEE802.lla/b/g, 802.1In, and 802.11ac standards, enterprise organizations can deploy the solution that best fits their needs. Enterprises can provide robust coverage using 802.Ha/b/g/n, or use6.4 wireless, VoIP, and SAN security 173802.1 lac for added reliability, and 802.1lac WiFi offers three times the performance of 802.1In WiFi.6.4.2.6 Scanning along the streetWith ubiquitous wireless Internet access, the opportunities for hackers to surreptitiously connect to remote networks have been increased. Both expert hackers and novices to wireless technology have the opportunity to exploit weaknesses in wireless networks.The most common type of wireless attack is called war driving, where hackers try to gain access to wireless networks on their laptops by driving around urban or suburban areas. Neighbors can attack to gain access to other neighbors' wireless networks to gain free Internet access or access confidential information. Airports, fast food restaurants, and coffee shops often provide Internet access, which also gives hackers the opportunity to compromise the data of otherThis also gives hackers the opportunity to compromise the data of other users. Hackers can even use hoc mode in public areas to try to connect to other computers.
