About the White Paper:
Traditional network security focuses on establishing a perimeter to keep outsiders at bay and on limiting access through password protection, smart cards or biometrics. Emerging Virtual Private Networks (VPNs) focus on secure site interconnection and remote access over the Wide Area Network (WAN). As e-business becomes imperative, organizations are exerting considerable effort and investing sizable budgets to secure back-office systems they have made accessible to customers and business partners. But a recent FBI study confirms what security experts have acknowledged for years: most security breaches occur within the corporate network, over a Local Area Network (LAN). Protecting the privacy and integrity of data transported over LANs is paramount to securing a corporation's most valuable asset: its intellectual property. Standards-based technologies like Internet Protocol Security (IPSec) can be used to create trusted, secure LAN workgroups.
This technology guide examines the risks associated with LAN-based intranets and extranets and the enabling technologies that can be employed to mitigate these risks. It describes how to build secure LANs using an integrated network-level approach that offers an optimum balance between security and performance. This guide considers deployment strategies for rolling out secure LAN workgroups in a manageable, cost-effective manner. |
