This book demonstrates that the first method often results in failure Responding in an ad hoc manner, with ill-defined tools and a lack of formal techniques, is costly and unproductive The second method has a far better success rate Analysts using NSM tools and techniques interpret integrated sources of network data to identify indications and form warnings, escalating them as actionable intelligence to decision makers, who respond to incidents Although the remainder of this book will explain how to take these steps, let's briefly apply them to the scenario of abnormally heavy router traffic In a case where an unusual amount of traffic is seen, NSM analysts would first check their statistical ata sources to confirm the findings of the network administrators Depending on the tools used, the analysts might discover an unusual amount of traffic flowing over an unrecognized port to a server on a laboratory network The NSM analysts might next query for all alert data involving the lab server over the last 24 hours, in an effort to identify potentially hostile events Assuming no obviously malicious alerts were seen, the analysts would then query for all session data for the same period The session data could show numerous conversations between the lab server and a variety of machines across the Internet, with all of the sessions initiated outbound by the lab server Finally, by taking a sample of full content data, the analysts could recognize the footprint of a new file-sharing protocol on a previously unseen port These steps might seem self-evident at first, but the work needed to implement this level of analysis is not trivial Such preparation requires appreciation for the principles already mentioned, along with the selection and deployment of tools and techniques yielding high-fidelity data Far too often security personnel spend thousands of dollars on equipment that produces little valuable information in the face of uncertainty The purpose of this book is to help readers prepare for and conduct efficient network-based analysis Having the right data on hand means faster and more accurate incident response, thereby preserving the assets that security professionals are bound to protect Hopefully you accept that a prevention-oriented security strategy is doomed to fail If not, consider whether or not you agree with these four statements 1 Most existing systems have security flaws that render them susceptible to intrusions, penetrations, and other forms of abuse Finding and fixing all these deficiencies is not feasible for technical and economic reasons Existing systems with known flaws are not easily replaced by systems that are more secure mainly because the systems have attractive features that are missing in the more secure systems, or else they cannot be replaced for economic reasons Developing systems that are absolutely secure is extremely difficult, if not generally impossible Even the most secure systems are vulnerable to abuses by insiders who misuse their privileges.

The NET Compact Framework supports in-memory bitmaps with the Bitmap21 class This class is derived from the Image class, which is a common base class for the Bitmap class and the Metafile class As we mentioned earlier in this chapter, metafiles are not supported in the NET Compact Framework But because the NET Compact Framework maintains consistency with the desktop NET Framework, our bitmap drawing method is called DrawImage (instead of, for example, DrawBitmap) On the desktop, where metafiles are supported, the DrawImage method draws both bitmaps and metafiles The dimensions of a bitmap are available through two properties of the Bitmap object: Height and Width The dimensions are also available through the ize property, which provides a convenient package for height and width These are read-only properties because an image cannot change size once it has been created On the desktop, the Bitmap class supports 12 constructors, while in the NET Compact Framework there are only 4 constructors You can create a bitmap in these ways:. 21 SystemDrawingBitmap.

It is important to understand that ASPNET Compatibility mode is not always needed For example, we will be examining how to use the ASPNET Membership Provider to authenticate access to WCF services This feature does not require the use of ASPNET Compatibility mode However, if you want to be able to access the Principal and Identity of a or use other security-related features user from the ASPNET such as File and URL Authorization, you will need to use ASPNET Compatibility mode In this scenario, WCF services act more like ASPNET Web Services because they have similar capabilities One important point is that you should not use ASPNET Compatibility mode if our intent is to host services outside of IIS or use other transports besides HTTP.Authentication Using Membership Providers ASPNET 20 provides a number of services such as Membership, Roles, Pro les, and more These services are prebuilt frameworks that developers can use without the need for writing additional code For example, the Membership service provides the capabilities to manage users, including the creation, deletion, and updating of users ASPNET also allows for Forms Authentication to use the Membership service to authenticate users for Web applications WCF provides a similar mechanism to authenticate user access to services against the Membership services This capability can be used whether or not there is an ASPNET Web application to onsider This means that any.
