An attacker searches a targeted web site for web pages that have not been
						publicized. Generally this involves mapping the published web site by
						spidering through all the published links and then attempt to access
						well-known debugging or logging pages, or otherwise predictable pages within
						the site tree. For example, if an attacker might be able to notice a pattern
						in the naming of documents and extrapolate this pattern to discover
						additional documents that have been created but are no longer externally
						linked. Using this, the attacker may be able to gain access to information
						that the targeted site did not intend to make public.
