Aquarmira water filter bottle review
A table top review of the Aquamira Water Filter Bottle. This 25 oz bottle holds 21 ounces with the filter and appears to filter at a rate of 8 oz a minute. This is a nice budget item at $22 and the replacement filters are $12. This filter will kill 99.9% of crypto and Giardia, however does not kill virus or bacteria so you will need to treat the water chemically for that. This is a great budget water purification bottle for backpackers, hikers, campers, hunters, and even great for your bug out bag or your survival kit, or emergency vehicle kit.

DEF CON 22 - Dan Kaminsky - Secure Random by Default
Secure Random By Default Dan Kaminsky Chief Scientist, White Ops As a general rule in security, we have learned that the best way to achieve security is to enable it by default. However, across operating systems and languages, random number generation is always exposed via two separate and most assuredly unequal APIs -- insecure and default, and secure but obscure. Why not fix this? Why not make JavaScript and PHP and Java and Python and even libc rand() return strong entropy? What are the issues stopping us? Should we just shell back to /dev/urandom, or is there merit to userspace entropy gathering? How does fork() and virtualization impact the question? What of performance, and memory consumption, and headless machines? Turns out the above questions are not actually rhetorical. Just because a change might be a good idea doesn't mean it's a simple one. This will be a deep dive, but one that I believe will actually yield a fix for the repeated *real world* failures of random number generation systems. Dan Kaminsky has been a noted security researcher for over a decade, and has spent his career advising Fortune 500 companies such as Cisco, Avaya, and Microsoft.Dan spent three years working with Microsoft on their Vista, Server 2008, and Windows 7 releases. Dan is best known for his work finding a critical flaw in the Internet’s Domain Name System (DNS), and for leading what became the largest synchronized fix to the Internet’s infrastructure of all time. Of the seven Recovery Key Shareholders who possess the ability to restore the DNS root keys, Dan is the American representative. Dan is presently developing systems to reduce the cost and complexity of securing critical infrastructure.

DEF CON 22 - Tess Schrodinger - From Raxacoricofallapatorius With Love
Slides Here: https://defcon.org/images/defcon-22/dc-22-presentations/Schrodinger/DEFCON-22-Tess-Schrodinger-Raxacoricofallapatorius-With-Love-Case-Studies.pdf From Raxacoricofallapatorius With Love: Case Studies In Insider Threat Tess Schrodinger Espionage, honey pots, encryption, and lies. Clandestine meetings in hotels. The naïve girl seduced by a suave businessman. The quiet engineer who was busted by the shredded to do list found in his trash. Encryption the NSA couldn’t crack. What motivates insiders to become threats? How were they caught? What are potential red flags to be aware of? Acquire a new awareness around what makes these people tick. Tess has over twenty years in law enforcement, investigation, forensics (bullets & blood, not 1s & 0s), and industrial security. She holds a Bachelor of Sociology, a Master of Security Management, and a graduate certificate in cybersecurity technology. One of her many current objectives is to bridge the gap between traditional security and cyber security by promoting awareness and education to the technologically ignorant who are often overwhelmed by the potential threats and how they can be targeted and to the technically gifted who are often unfamiliar with the threats, vulnerabilities, and mitigation techniques that lie outside their world of technology.
