Problem Statement : Virus ....DOS(denail of services) ....spoofing ...hacking Innovative exploit: DNS combined with NAT ...is a potent combination either DNS can be compromised or if not NAT can be exploited.... while NAT is more safer and not easily detectable exploit ....while DNS may resolve appropriately ....by implementing NAT (not much compromising of embedded OS or other means required) ....a URL redirection to anonymous or 100% replica website can possible ....users can be coyyed ...exploited for e-commerce, online content serving etc, dynamic bandwidth provisioning for sessions or clients accessing the medium viz. if DNS gets resolved properly ...use url-redirection and session management by implementing NAT, ...DNS vulnerabilities and manipulations can be understood from the document below viz. projects.pdf and also refer to else where on the web (say sans.org ...supposed to be a benchmarking and certification agency) Opportunity: understanding and interpreting from pop protocols ...communications-means ...given the context and nature of internet or www ...further to as envisaged in the document referred below viz. projects.pdf or as articulated or published by this individual(refer to usage of telephone-number ...as a interface to medium internet or www ...further to as illustrated in "opportunity_vulnerabilities_medium_www_internet.txt" as a remedy or establish a virtual link using https or ssh using some tracable viz. identification viz. processor-id, mac-id(supposed to be unique network identity ...benchmarking network equipment and not virtual ...may refer to pre-registrable and traceability DNS ...as envisaged in the document projects.pdf"),session-validity tokens ...offering integrity of transactions on the medium www or internet with under-written guarantee offering the same ??(questionable and left to use-case modelling) Note: The above problem statement having been encountered in various scenarios and detailed in various 'Proof of concepts' as mentioned in 'http://uk.geocities.com/ravivenkatus/projects.pdf' ....apply appropriate 'use-case' modeling and arrive at a workable and feasible solution both commercially and techinically viable. -----------------------------------------------------------------------------------------------
