Wireless Security Starts at the Endpoint
by Dr. Tina Bird - Security Architect, InfoExpress - Monday, 25 April 2005.
While all network topologies will benefit from policy enforcement technologies, wireless networks gain some of the most significant advantages. Even relatively simple checks Ė like verifying that the anti-virus process is up to date and running Ė can greatly reduce the chances of a virus or Trojan penetrating the wireless infrastructure. And an enforcement mechanism that requires all laptops to have critical patches, up-to-date and running anti-virus programs, no file sharing and encrypted storage for corporate documents will greatly reduce the chances of a laptop leaking sensitive data when connecting to the corporate network wirelessly from hotspots at an airport lounge or coffee shop.
Thus, the new wireless security paradigm starts at the endpoint, combining inspection and remediation tools with network-based dynamic access controls to let colleagues take full advantage of wireless network ease and convenience, while keeping competitors and other digital vermin out.
