DShield
DShield is a community-based collaborative firewall log correlation system. It receives logs from volunteers worldwide and uses them to analyze attack trends. It is used as the data collection engine behind the SANS Internet Storm Center (ISC). DShield was officially launched end of November 2000 by Johannes Ullrich. Since then, it has grown to be a dominating attack correlation engine with worldwide coverage. DShield is regularly used by the media to cover current events. Analysis provided by DShield has been used in the early detection of several worms, like "Ramen", Code Red, "Leaves", "SQL Snake" and more. DShield data is regularly used by researchers to analyze attack patterns. The goal of the DShield project is to allow access to its correlated information to the public at no charge to raise awareness and provide accurate and current snapshots of internet attacks. Several data feeds are provided to users to either include in their own web sites or to use as an aide to analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Internet Storm Center
{{multiple issues, {{no footnotes, date=November 2017 {{primarysources, date=February 2010 The Internet Storm Center (ISC) is a program of the SANS Technology Institute, a branch of the SANS Institute which monitors the level of malicious activity on the Internet, particularly with regard to large-scale infrastructure events. History The ISC evolved from "Incidents.org", a site initially founded by the SANS Institute to assist in the public-private sector cooperation during the Y2K cutover. In 2000, Incidents.org started to cooperate with DShield to create a Consensus Incidents Database (CID). It collected security information from cooperating sites and agencies for mass analysis. On March 22, 2001, the SANS CID was responsible for the early detection of the "Lion" worm attacks on various facilities. The quick warning and counter-efforts organized by the CID were instrumental in controlling the damage done by this worm, which otherwise might have been considerably worse. Lat ...

ShieldsUP
ShieldsUP is an online port scanning service created by Steve Gibson of Gibson Research Corporation. The purpose of the utility is to alert the users of any ports that have been opened through their firewalls or through their NAT routers, which can be used by malicious users to take advantage of security vulnerabilities. The utility scans the most common file sharing ports, as well as all service ports (1-1056), and user defined ports, in sets of 64. It is often recommended for checking port vulnerabilities. The scanning servers have the static IP addresses An Internet Protocol address (IP address) is a numerical label such as that is connected to a computer network that uses the Internet Protocol for communication..

Firewall (networking)
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet. History The term ''firewall'' originally referred to a wall intended to confine a fire within a line of adjacent buildings. Later uses refer to similar structures, such as the metal sheet separating the engine compartment of a vehicle or aircraft from the passenger compartment. The term was applied in the late 1980s to network technology that emerged when the Internet was fairly new in terms of its global use and connectivity. The predecessors to firewalls for network security were routers used in the late 1980s. Because they already segregated networks, routers could apply filtering to packets crossing them. Before it was used in real-life computing, the term appeared in the 1983 computer-hacking movie ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ZDNet
ZDNET is a business technology news website owned and operated by Red Ventures. The brand was founded on April 1, 1991, as a general interest technology portal from Ziff Davis and evolved into an enterprise IT-focused online publication. History Beginnings: 1991 to 1995 ZDNET began as a subscription-based digital service called "ZiffNet" that offered computing information to users of CompuServe. It featured computer industry forums, events, features and searchable archives. Initially, ZiffNet was intended to serve as a common place to find content from all Ziff-Davis print publications. As such, ZiffNet was an expansion on an earlier online service called PCMagNet for readers of PC Magazine. Launched in 1988, PCMagNet in turn was the evolution of Ziff Davis' first electronic publishing venture, a bulletin board, which launched in 1985. On June 20, 1995, Ziff-Davis announced the consolidation of its online information services under a single name, ''ZD Net''. The service ...

Code Red (computer Worm)
Code Red was a computer worm observed on the Internet on July 15, 2001. It attacked computers running Microsoft's IIS web server. It was the first large scale, mixed threat attack to successfully target enterprise networks. The Code Red worm was first discovered and researched by eEye Digital Security employees Marc Maiffret and Ryan Permeh when it exploited a vulnerability discovered by Riley Hassell. They named it "Code Red" because Mountain Dew Code Red was what they were drinking at the time. Although the worm had been released on July 13, the largest group of infected computers was seen on July 19, 2001. On that day, the number of infected hosts reached 359,000. It spread worldwide but was particularly prevalent in North America, Europe and Asia (including China and India). Concept Exploited vulnerability The worm showed a vulnerability in the growing software distributed with IIS, described in Microsoft Security Bulletin MS01-033, for which a patch had been available a ...

SPEWS
The Spam Prevention Early Warning System (SPEWS) was an anonymous service that maintained a list of IP address ranges belonging to internet service providers (ISPs) that host spammers and show little action to prevent their abuse of other networks' resources. It could be used by Internet sites as an additional source of information about the senders of unsolicited bulk email, better known as spam. SPEWS is no longer active. A successor, the Anonymous Postmaster Early Warning System (APEWS), appeared in January 2007. Overview SPEWS itself published a large text file containing its listings, and operated a database where web users could query the reasons for a listing. Users of SPEWS could access these data via DNS for use by software for DNSBL anti-spam techniques. For instance, many mail sites used the SPEWS data provided at spews.relays.osirusoft.com. All DNSBLs hosted by Osirusoft were shut down on August 27, 2003 after several weeks of denial of service attacks. A number ...
