Stefan Savage (born 1969) is an American computer science researcher, currently a Professor in the Systems and Networking Group at the University of California, San Diego. There, he holds the Irwin and Joan Jacobs Chair in Information and Computer Science. Savage is widely cited in computer security, particularly in the areas of email spam, network worms and malware propagation, distributed denial of service (DDOS) mitigation and traceback, automotive hacking and wireless security. He received his undergraduate degree at Carnegie Mellon and his Ph.D. from the University of Washington. Career In 1999, Savage's research team published ''TCP Congestion Control with a Misbehaving Receiver'', which uncovered protocol flaws in the TCP protocol that carries most Internet traffic. By exploiting these flaws, Savage proposed means for attackers to evade congestion control, allowing attackers to monopolize crowded network connections that would otherwise be shared by multiple users.

Stochastic
Stochastic (, ) refers to the property of being well described by a random probability distribution. Although stochasticity and randomness are distinct in that the former refers to a modeling approach and the latter refers to phenomena themselves, these two terms are often used synonymously. Furthermore, in probability theory, the formal concept of a ''stochastic process'' is also referred to as a ''random process''. Stochasticity is used in many different fields, including the natural sciences such as biology, chemistry, ecology, neuroscience, and physics, as well as technology and engineering fields such as image processing, signal processing, information theory, computer science, cryptography, and telecommunications. It is also used in finance, due to seemingly random changes in financial markets as well as in medicine, linguistics, music, media, colour theory, botany, manufacturing, and geomorphology. Etymology The word ''stochastic'' in English was originally used as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ishwar Ramani
''Ishvara'' () is a concept in Hinduism, with a wide range of meanings that depend on the era and the school of Hinduism.Monier Monier Williams, Sanskrit-English dictionarySearch for Izvara University of Cologne, Germany In ancient texts of Hindu philosophy, depending on the context, ''Ishvara'' can mean supreme Self, ruler, lord, king, queen or husband. In medieval era Hindu texts, depending on the school of Hinduism, ''Ishvara'' means God, Supreme Being, personal God, or special Self. ''Ishvara'' is primarily an epithet of Shiva.James Lochtefeld, "Ishvara", The Illustrated Encyclopedia of Hinduism, Vol. 1: A–M, Rosen Publishing. , page 306 In Shaivism, ''Ishvara'' is an epithet of Shiva. For many Vaishnavas, it is synonymous with Vishnu, like in his epithet of Venkateswara. In traditional Bhakti movements, ''Ishvara'' is one or more deities of an individual's preference ( Iṣṭa-devatā) from Hinduism's polytheistic canon of deities. In modern-day sectarian movem ...

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...

SQL Slammer
SQL Slammer is a 2003 computer worm that caused a denial of service on some Internet hosts and dramatically slowed general Internet traffic. It spread rapidly, infecting most of its 75,000 victims within ten minutes. The program exploited a buffer overflow bug in Microsoft's SQL Server and Desktop Engine database products. Although thMS02-039patch had been released six months earlier, many organizations had not yet applied it. The most infected regions were Europe, North America, and Asia (including East Asia and India). Technical details The worm was based on proof of concept code demonstrated at the Black Hat Briefings by David Litchfield, who had initially discovered the buffer overflow vulnerability that the worm exploited. It is a small piece of code that does little other than generate random IP addresses and send itself out to those addresses. If a selected address happens to belong to a host that is running an unpatched copy of Microsoft SQL Server Resolution Service lis ...

Code Red II
Code Red II is a computer worm similar to the Code Red worm. Released two weeks after Code Red on August 4, 2001, it is similar in behavior to the original, but analysis showed it to be a new worm instead of a variant. Unlike the first, the second has no function for attack; instead it has a backdoor that allows attacks. The worm was designed to exploit a security hole in the indexing software included as part of Microsoft's Internet Information Server (IIS) web server software. A typical signature of the Code Red II worm appears in a web server log as: GET /default.ida?XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX %u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801 %u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3 %u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a HTTP/1.0 While the original wo ...

Network Telescope
A network telescope (also known as a packet telescope, darknet, Internet motion sensor or black hole) is an Internet system that allows one to observe different large-scale events taking place on the Internet. The basic idea is to observe traffic targeting the dark (unused) address-space of the network. Since all traffic to these addresses is suspicious, one can gain information about possible network attacks (random scanning worms, and DDoS backscatter) as well as other misconfigurations by observing it. The resolution of the Internet telescope is dependent on the number of IP addresses it monitors. For example, a large Internet telescope that monitors traffic to 16,777,216 addresses (the Internet telescope in IPv4), has a higher probability of observing a relatively small event than a smaller telescope that monitors 65,536 addresses (a Internet telescope). The naming comes from an analogy to optical telescopes, where a larger physical size allows more photons to be observed. ...
