I was reading Joseph Tardo's (Nevis Networks) new Illuminations blog and found the topic of his latest post ""Built-in, Overlay or Something More Radical?" regarding the possible future of network security quite interesting. Joseph (may I call you Joseph?) recaps the topic of a research draft from Stanford funded by the "S tanford Clean Slate Design for the Internet " project that discusses an approach to network security called SANE . The notion of SANE (AKA Ethane) is a policy-driven security services layer that utilizes intelligent centrally-located services to replace many of the underlying functions provided by routers, switches and security products today: Ethane is a new architecture for enterprise networks which provides a powerful yet simple management model and strong security guarantees. Ethane allows network managers to define a single, pay per click banners etwork-wide, fine-grain policy, and then enforces it at every switch. Ethane policy is defined over human-friendly names (such as "bob, "payroll-server", or "http-proxy) and dictates who can talk to who and in which manner. For example, a policy rule may specify that all guest users who have not authenticated can only use HTTP and that all of their traffic must traverse a local web proxy. Ethane has a number of salient properties difficult to achieve with network technologies today. First, the global security policy is enforced at each switch in a manner that is resistant to poofing.

Ok, now these 'storage towers' make me go uuuuhh and aaaaah: Wogg 17 ellipse help desk consulting ower . BEAUTIFUL!

Kash Mansouri writes: The Street Light: The Economist on Bush on Trade - Yahoo! News: Economy News : The Economist takes a massive dive today, as they fashion marketing programs ontinue to bizarrely and irresponsibly assume the best (or maybe "the least bad" would be more accurate) of the Bush administration. The last two paragraphs of the story contain the offending bits: Despite a dispiriting start that saw the imposition of steel tariffs, the Bush administration has made great efforts on trade, pushing forward with both multilateral and bilateral deals. Its biggest goal, a substantive deal from the Doha round of World Trade Organisation negotiations, is currently on life support. But the administration has managed to secure a variety of smaller deals, while letting steel tariffs die a death at the hands of the WTO. Now even progress of that sort may end. Already, the Democratic influence is showing on the administration's trade team. On Friday March 30th it announced that it was imposing countervailing tariffs on Chinese manufacturers of high-gloss paper to offset indirect subsidies they get from the state. America has usually steered clear of this sort of action against state-run economies, saying it is prohibitively difficult to calculate excess subsidies. But the gaping trade deficit with China, and growing protectionist forces, have altered the political calculus. New tariffs of up to 20% will be imposed immediately. The American economy will survive without cheap Chinese paper products.
