The author of this article and his sources express surprise that Cisco would pay big money for an open-source product that anyone can use.&lt;p&gt;Cisco paid just about 10x trailing revenue for Sourcefire, a public company that had managed to dominate enterprise network security and which competed directly with products that had been cash cows for Cisco for over a decade. Cisco has for as long as I&amp;#x27;ve been in the industry --- in fact, for as long as there&amp;#x27;s been that industry --- been the single most important acquirer of network security companies. They acquired security companies with the same fervor in 1998 as they do today.&lt;p&gt;Cisco&amp;#x27;s acquisition of Sourcefire might qualify as the single least interesting story in information security in the last 5 years.&lt;p&gt;Want to make a couple hundred million dollars? You too can do what Sourcefire did: start an open source project that appeals to enterprise teams who spend monopoly money to buy products (that is, start any enterprise-relevant open source project). Get thousands of people to use it. Then start a company and hire an inside sales team. Have them call company after company and ask, &amp;quot;Do you use our open-source project?&amp;quot; Sell extra stuff to the people who say &amp;quot;yes&amp;quot;.</text><parent_chain></parent_chain></comment><story><title>The Mercenaries: Ex-NSA hackers are shaping the future of cyberwar</title><url>http://www.slate.com/articles/technology/future_tense/2014/11/how_corporations_are_adopting_cyber_defense_and_around_legal_barriers_the.single.html</url><text></text></story>

Black Hat attendance is in the high thousands. A plurality of those attending are IT professionals --- people that wouldn&amp;#x27;t have the technical capability to take over a botnet even if they wanted to. Even if you broadened the definition of &amp;quot;hacking back&amp;quot;, as some people do, to recon activities like port scans. No part of this anecdote makes sense.&lt;p&gt;For my part (I&amp;#x27;m a security researcher by background, though that&amp;#x27;s not what I&amp;#x27;m doing now, and I&amp;#x27;ve presented at Black Hat numerous times): not only have I never met a professional who claimed to have &amp;quot;hacked back&amp;quot; anything, but I&amp;#x27;ve never even met one who didn&amp;#x27;t think that was a crazy idea.&lt;p&gt;There is a difference between major organized efforts to bring down botnets and &amp;quot;hackback&amp;quot; the way the term gets associated with Endgame.</text><parent_chain></parent_chain></comment><story><title>The Mercenaries: Ex-NSA hackers are shaping the future of cyberwar</title><url>http://www.slate.com/articles/technology/future_tense/2014/11/how_corporations_are_adopting_cyber_defense_and_around_legal_barriers_the.single.html</url><text></text></story>
