      Improving Web Application Security: Threats and Countermeasures
    ------------------------------------------------------------------------

    SUMMARY

    This guide gives you a solid foundation for designing, building, and
    configuring secure ASP.NET Web applications. Whether you have existing
    applications or are building new ones, you can apply the guidance to help
    you make sure that your Web applications are hack-resilient.

    DETAILS

    Abstract:
    This guide helps you build hack-resilient applications. A hack-resilient
    application is one that reduces the likelihood of a successful attack and
    mitigates the extent of damage if an attack occurs. A hack-resilient
    application resides on a secure host (server) in a secure network and is
    developed using secure design and development guidelines.

    Web application security must be addressed across the tiers and at
    multiple layers. A weakness in any tier or layer makes your application
    vulnerable to attack. Figure 1 shows the scope of the guide and the
    three-layered approach that it uses: securing the network, securing the
    host, and securing the application. It also shows the process called
    threat modeling, which provides a structure and rationale for the security
    process and allows you to evaluate security threats and identify
    appropriate countermeasures. If you do not know your threats, how can you
    secure your system?

    Figure 1. Scope of Improving Web Application Security: Threats and
    Countermeasures
    (http://msdn.microsoft.com/library/en-us/dnnetsec/html/f00thcm01.gif)

    The guide addresses security across the three physical tiers shown in
    Figure 1. It covers the Web server, remote application server and database
    server. At each tier, security is addressed at the network layer, host
    layer, and application layer. Figure 1 also shows the configuration
    categories that the guide uses to organize the various security
    configuration settings that apply to the host and network, and the
    application vulnerability categories, used to structure application
    security considerations.
