Suddenly your Web server becomes unavailable. When you investigate, you realize that a flood of packets is surging into your network. You have just become one of the hundreds of thousands of victims of a denial-of-service attack, a pervasive and growing threat to the Internet. What do you do? Internet Denial of Service sheds light on a complex and fascinating form of computer attack that impacts the confidentiality, integrity, and availability of millions of computers worldwide. It tells the network administrator, corporate CTO, incident responder, and student how DDoS attacks are prepared and executed, how to think about DDoS, and how to arrange computer and network defenses. It also provides a suite of actions that can be taken before, during, and after an attack. The authors' extensive experience in handling denial-of-service attacks and researching defense approaches is laid out clearly in practical, detailed terms.
Today we find web applications in every environment independent of a company's size and even in home networks. This fact made web applications also attractive to cyber criminals as there are new attack vectors like Cross Site Scripting, Remote File Inclusions (RFI) and SQL Injections. Such so called web based attacks can be found on every vulnerability statistic because of these attacks are so widespread. Criminals not only break into web applications, they also overtake whole web servers which than can become part of a botnet or even become a command and control server of such. GlastopfNG, is a honeypot specialized on simulating a vulnerable web server/application to become a target of automated or even manual attack. Instead of trying to block these attacks Glastopf tries to get as much information as possible about the attacker and the used attack itself. This gathered information can then be used in different ways to protect real applications in the future against such attacks.
"There are a lot of assumptions about Hackers, and a lot of the assumptions are wrong."
_The story of a massive DDoS attack and how takes out a major piece of internet infrastructure, causing huge outages across the World. Watch it spread like a disease through the narrative.
_A fantasy tale about how knowledge is misused and abused, the technology background is solid, the reader will learn the real facts about the core principles of tor and the onion routing while is trapped by the story.
_my failure to use Tor could get me killed. I put the blame directly on the country and some of its citizens.
_The media and politicians fuel the fire. This has spread globally. People can't comprehend the danger of draconian legislation or persecution of minorities.
