  28. 802.11 WLAN Security ServerCertificate ClientCertificate Wireless Security

  29. Wireless Security Policy • Creates a set of rules and standards for users, administrators, and managers to follow. • Bolster awareness of security and proper usage techniques. • Create a proactive environment where the tools, methods, and procedures are in place to deter attackers and combat the threats effectively. • Establishes a security model for the existing or the soon-to-be-developed network. • Helps to eliminate some of the threats to 802.1x networks.

  30. Physical Security • Physical security standards should be in place to prevent an intruder from gaining unauthorized access or to detect the intruder if physical access is gained to the enterprise premises. • Installing a managed, supported, and Secure WLAN network throughout the enterprise, (removes the motivation for employees to install rogue APs). • Provide employees with a secure WLAN infrastructure supported by an enterprise IT department. I’ll just buy my OWN access point!

  31. How to Secure your WLAN • Install Firewall in the Data Center to secure network. • Install personal firewall software on all connected PCs and laptops. • Remove rogue unauthorized Access Point from the network. • Use password protection on all sensitive folders and files. • Install Anti-Virus on all PCs and laptops.

  32. Wireless Security Components • Authentication • between the client and the authentication server. • Authorization • Controlled by the WLAN membership in combination with the access controls applied at the access router terminating the VLAN. • Accounting • Provided by the RADIUS accounting communicated by the APs to the RADIUS server. • Encryption • At the link layer between the WLAN client and the AP. • are automatically derived during the authentication process.

  33. TeraMax Security Support • Enhanced Security • WEP+ encryption • Encryption • DES (56-bit) • Blowfish (128 bit) • AES (128 Bit) • Authentication • WPA • WPA2 • Supports • RADIUS Authentication • Accounting • Firewall

  34. RADIUS Authentication • RADIUS is a widely deployed protocol, based on a client/server model, that enables centralized authentication, authorization, and accounting for network access • RADIUS is the standard for managing network access for VPN, dial-up, and wireless networks • Use RADIUS to manage network access centrally across many types of network access • RADIUS servers receive and process connection requests or accounting messages from RADIUS clients or proxies

  35. Communicates to the RADIUS client to grant or deny access 4 RADIUS Client 2 Forwards requests to a RADIUS server Domain Controller Client 3 Authenticates requests and stores accounting information Dials in to a local RADIUS client to gain network connectivity 1 How Centralized Authentication Works Remote Access Server RADIUS Server
