Many sites have taken notice of Bitcoin and have published some very thoughtful “what is Bitcoin,” “How-to get started” documentation. But the resources available to address Bitcoin are few, and primarily oriented toward enthusiasts, casual hobbyists, or those interested in making and securing a profit off of Bitcoin generation (“mining”). In this post, we make an effort to extend the Bitcoin security body of knowledge, but from an organizational perspective: what are the risks associated with adopting Bitcoin, intentionally or unintentionally.]]> http://blogs.cisco.com/security/bitcoin-security-architecture-a-brief-overview/feed/ 9 http://blogs.cisco.com/security/iphone-location-tracking-important-even-if-it-doesnt-matter-to-you/ http://blogs.cisco.com/security/iphone-location-tracking-important-even-if-it-doesnt-matter-to-you/#comments Mon, 25 Apr 2011 19:50:54 +0000 Seth Hanford http://blogs.cisco.com/?p=28557 consolidated.db. As we discussed in the Cyber Risk Report, even though Apple has disclosed location tracking via their Privacy Policy, significant commentary online suggests that users are surprised to learn how it is accomplished. The researchers whose efforts have brought this location tracking to wide attention were aware that forensics experts knew about it, but developed their tool to bring this to a wider attention. By all accounts, they have succeeded in raising awareness; what remains is to understand what should be done from here.]]> http://blogs.cisco.com/security/iphone-location-tracking-important-even-if-it-doesnt-matter-to-you/feed/ 0 http://blogs.cisco.com/security/incomplete-reporting-of-law-enforcement-electronic-surveillance-may-skew-risk-assessments/ http://blogs.cisco.com/security/incomplete-reporting-of-law-enforcement-electronic-surveillance-may-skew-risk-assessments/#comments Wed, 20 Apr 2011 00:09:06 +0000 Seth Hanford http://blogs.cisco.com/?p=28092 http://blogs.cisco.com/security/incomplete-reporting-of-law-enforcement-electronic-surveillance-may-skew-risk-assessments/feed/ 0 http://blogs.cisco.com/security/mobile-device-security-fragmented-complex-and-taking-a-backseat-to-usability/ http://blogs.cisco.com/security/mobile-device-security-fragmented-complex-and-taking-a-backseat-to-usability/#comments Thu, 10 Mar 2011 14:51:21 +0000 Seth Hanford http://blogs.cisco.com/?p=22988 smartphone sales have finally eclipsed PC sales for the first time in history, and that's without counting the millions of non-phone devices like tablets that tend to share the operating systems and functionality of their phone-based brethren. Based on these numbers, it is disappointing to see the state of security in devices that have taken the world by storm. Design decisions, policies, and various stakeholders have resulted in a fairly hostile device ecosystem in which, for example, users can be easily fooled into installing malware on their phones.]]> http://blogs.cisco.com/security/mobile-device-security-fragmented-complex-and-taking-a-backseat-to-usability/feed/ 1 http://blogs.cisco.com/security/controlling-the-flow-of-information-in-the-21st-century/ http://blogs.cisco.com/security/controlling-the-flow-of-information-in-the-21st-century/#comments Mon, 07 Feb 2011 17:54:17 +0000 Seth Hanford http://blogs.cisco.com/?p=19628 http://blogs.cisco.com/security/controlling-the-flow-of-information-in-the-21st-century/feed/ 0 http://blogs.cisco.com/security/gawker-media-compromise-lessons-learned/ http://blogs.cisco.com/security/gawker-media-compromise-lessons-learned/#comments Wed, 15 Dec 2010 19:56:44 +0000 Seth Hanford http://blogs.cisco.com/?p=15927 http://blogs.cisco.com/security/gawker-media-compromise-lessons-learned/feed/ 0
