Fourth Edition Sheds New Light on Open Source Intelligence Collection and Analysis.
Author Michael Bazzell has been well known and respected in government circles for his ability to locate personal information about any target through Open Source Intelligence (OSINT). In this book, he shares his methods in great detail. Each step of his process is explained throughout sixteen chapters of specialized websites, application programming interfaces, and software solutions. Based on his live and online video training at IntelTechniques.com, over 250 resources are identified with narrative tutorials and screen captures.

With more than 60 practical and creative hacks, this book helps you turn Raspberry Pi into the centerpiece of some cool electronics projects. Want to create a controller for a camera or a robot? Set up Linux distributions for media centers or PBX phone systems? That’s just the beginning of what you’ll find inside Raspberry Pi Hacks.
If you’re looking to build either a software or hardware project with more computing power than Arduino alone can provide, Raspberry Pi is just the ticket. And the hacks in this book will give you lots of great ideas.Use configuration hacks to get more out of your PiBuild your own web server or remote print serverTake the Pi outdoors to monitor your garden or control holiday lightsConnect with SETI or construct an awesome Halloween costumeHack the Pi’s Linux OS to support more complex projectsDecode audio/video formats or make your own music playerAchieve a low-weight payload for aerial photographyBuild a Pi computer cluster or a solar-powered lab

Distributed Denial of Service (DDoS) attacks are attempts to overwhelm a computer system in order to deny access by legitimate users. They are generally unstoppable, but there is a good deal of on-going research on methods to reduce their negative effects. This paper will deal with the design of a model that simulates such an attack. The simulation model is then used to study possible ways to defend against these attacks. Three experiments are run: 1) using a priority queue to sort messages from clients based on how many connections they have open on the server; 2) limiting the number of connections each client can create; and 3) having the server forcefully delete the oldest established connection, whenever its connection table becomes full. Results show that method 1 is totally ineffective while method 2 somewhat improves the overall performance of the system. However, method 3, combined with method 2, produces significantly improved performance against a DDoS attack.
