Prolexic Technologies
Prolexic Technologies was a US-based provider of security solutions for protecting websites, data centers, and enterprise IP applications from Distributed Denial of Service (DDoS) attacks at the network, transport, and application layers. It operated a DDoS mitigation platform and a global network of traffic scrubbing centers. Real-time monitoring and mitigation services were provided by a 24/7 security operations control center (SOCC). Prolexic indicated its DDoS mitigation services make websites, data centers and enterprise IP applications harder to take down via DDoS attacks. In February 2014, cybersecurity and cloud services company Akamai Technologies acquired Prolexic Technologies. History In 2003 Prolexic Technologies was founded by Barrett Lyon and was the subject of the book ''Fatal System Error'' by Joseph Menn.

Payment Card Industry Data Security Standard
The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard used to handle credit cards from major card brands. The standard is administered by the Payment Card Industry Security Standards Council and its use is mandated by the card brands. The standard was created to better control cardholder data and reduce credit card fraud. Validation of compliance is performed annually or quarterly, by a method suited to the volume of transactions handled: * Self-Assessment Questionnaire (SAQ) * Firm-specific Internal Security Assessor (ISA) * External Qualified Security Assessor (QSA) History Originally, the major card brands started five different security programs: *Visa's Cardholder Information Security Program * MasterCard's Site Data Protection *American Express's Data Security Operating Policy *Discover's Information Security and Compliance * JCB's Data Security Program The intentions of each were roughly similar: to create an additional level of ...

Denial-of-service Attack
In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack, as simply attempting to block a single source is insufficient because there are multiple sources. A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade. Criminal perpetrators of DoS attacks oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UDP Flood Attack
A UDP flood attack is a volumetric denial-of-service (DoS) attack using the User Datagram Protocol (UDP), a sessionless/connectionless computer networking protocol. Using UDP for denial-of-service attacks is not as straightforward as with the Transmission Control Protocol (TCP). However, a UDP flood attack can be initiated by sending a large number of UDP packets to random ports on a remote host. As a result, the distant host will: * Check for the application listening at that port; * See that no application listens at that port; * Reply with an ICMP Destination Unreachable packet. Thus, for a large number of UDP packets, the victimized system will be forced into sending many ICMP packets, eventually leading it to be unreachable by other clients. The attacker(s) may also spoof the IP address of the UDP packets, ensuring that the excessive ICMP return packets do not reach them, and anonymizing their network location(s). Most operating systems mitigate this part of the attack by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zero-day Attack
A zero-day (also known as a 0-day) is a computer-software vulnerability previously unknown to those who should be interested in its mitigation, like the vendor of the target software. Until the vulnerability is mitigated, hackers can exploit it to adversely affect programs, data, additional computers or a network. An exploit taking advantage of a zero-day is called a zero-day exploit, or zero-day attack. The term "zero-day" originally referred to the number of days since a new piece of software was released to the public, so "zero-day software" was obtained by hacking into a developer's computer before release. Eventually the term was applied to the vulnerabilities that allowed this hacking, and to the number of days that the vendor has had to fix them. Once the vendors learn of the vulnerability, they will usually create patches or advise workarounds to mitigate it. The more recently that the vendor has become aware of the vulnerability, the more likely it is that no fix or mit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SYN Flood
A SYN flood is a form of denial-of-service attack in which an attacker rapidly initiates a connection to a server without finalizing the connection. The server has to spend resources waiting for half-opened connections, which can consume enough resources to make the system unresponsive to legitimate traffic. The packet that the attacker sends is the SYN packet, a part of TCP's three-way handshake used to establish a connection. Technical details When a client attempts to start a TCP connection to a server, the client and server exchange a series of messages which normally runs like this: #The client requests a connection by sending a SYN (''synchronize'') message to the server. #The server ''acknowledges'' this request by sending SYN-ACK back to the client. #The client responds with an ACK, and the connection is established. This is called the TCP three-way handshake, and is the foundation for every connection established using the TCP protocol. A SYN flood attack works ...

Web Application Framework
A web framework (WF) or web application framework (WAF) is a software framework that is designed to support the development of web applications including web services, web resources, and web APIs. Web frameworks provide a standard way to build and deploy web applications on the World Wide Web. Web frameworks aim to automate the overhead associated with common activities performed in web development. For example, many web frameworks provide libraries for database access, templating frameworks, and session management, and they often promote code reuse. Although they often target development of dynamic web sites, they are also applicable to static websites. History As the design of the World Wide Web was not inherently dynamic, early hypertext consisted of hand-coded HTML text files that were published on web servers. Any modifications to published pages needed to be performed by the pages' author. In 1993, the Common Gateway Interface (CGI) standard was introduced for interfacin ...

BT Global Services
BT Global is a division of United Kingdom telecommunications company BT Group that provides global security, cloud and networking services to multinational companies worldwide, with operations in 180 countries. It was established in July 2000 as BT Ignite. History Renaming BT Group began operating as a private corporation after the Telecommunications Act 1984. During the 1990s, between the loosening of national telecom monopolies and the current (largely) liberalised market, BT Group entered into a number of alliances in order to serve its mainly, then, UK-based multi-national customers. From the 90's through the early 2000s, BT Group, then known as British Telecom, struggled. The company failed to secure a strong partner, struggled to expand internationally, and had significant debt. In 2002, the attempt at an alliance (Concert 2 with AT&T) was disbanded. Thereafter, the company brought together a number of joint ventures, partly owned assets and wholly owned subsidiaries into ...

Venture Round
A venture round is a type of funding round used for venture capital financing, by which startup companies obtain investment, generally from venture capitalists and other institutional investors.

Introduce companies to investors. *A lead investor, typically the best known or most aggressive venture capital firm that is participating in the investment, or the one contributing the largest amount of cash. The lead investor typically oversees most of the negotiation, legal work, due diligence, and other formalities of the investment. It may also introduce the company to other investors, generally in an informal unpaid capacity. *Co-investors, other major investors who contribute alongside the lead investor *Follow-on or piggyback investors.
