Executive Summary Today’s mobile workforce increasingly demands convenient and secure access to the Internet using mobile devices (such as notebook and handheld PCs) with HP Wi-Fi and other mobile connectivity solutions. A secure solution enables a mobile worker to gain safe network access in areas where it is traditionally hard to deploy "wired" networks.

Mobile Device Security and HP Protect Tools HP saw the need for better security solutions very early, and started devoting resources to addressing this issue. As a result of this proactive effort, HP has developed a solution – the HP ProtectTools Security Manager – that not only meets mobility and wireless requirements, but is also extensible and therefore can easily grow to handle new threats and offer new technologies as they become available.

Wired Equivalent Privacy Although most wireless security concerns have little or nothing to do with the wireless nature of the devices, there is some validity to the apprehension regarding the vulnerabilities of the Wired Equivalent Privacy key. WEP is an encryption algorithm designed to provide wireless security for 802.11 wireless networks. It was developed by IEEE volunteers.

Vendor Solutions for WEP Vulnerability Other security measures Hiding the SSID Limiting the RF propagation Hiding the Service Set Identifier (SSID) is not a valid security measure. Because management frames on 802.11 Wireless LANs are always sent in the clear, this mode of operation does not provide adequate security Limiting propagation is hard, although it is possible in certain environments Wi-Fi Protected Access Fortunately, the Wi-Fi Protected Access (WPA) subset of the 802.

The following screen shots show available WPA authentication and encryption supported on HP notebook PCs. WPA Pre-Shared Key While WPA and 802.11i allow EAP Authentication, this solution may not be affordable or available for home users. In addition, home users don’t typically have access to an authentication server. In these instances, most available consumer devices offer authentication within the device with a WPA pre-shared key. This makes a great solution for home use and office or small business use.

Virtual Private Network vs. Reverse Proxy Most people are using Virtual Private Network (commonly known as Tunnels) to connect to their corporate networks. Even consumer-grade wireless and wired routers have VPN and some Firewall and DMZ capabilities. An alternative to VPN that is rapidly gaining acceptance is the use of reverse proxy to obtain pervasive access.

Conclusion A high-level understanding of the issues associated with wireless security is key to protecting your data and network. This is true of any kind of connection – wire-line or wireless. Over the past eight years, wireless security has undergone major changes to address the vulnerabilities in Wired Equivalent Privacy. Wireless LAN can be more secure, provided that we apply the new available solutions. The IEEE 802.

Now and into the foreseeable future, mobile consumers and users can feel safer in implementing wireless solutions by remembering that standards-based wireless network security plus HP ProtectTools security technology equals a more secure mobile computing environment.
