A Sense of Time for Node.Js: Timeouts As a Cure for Event Handler Poisoning
A Sense of Time for Node.js: Timeouts as a Cure for Event Handler Poisoning Anonymous Abstract—The software development community has begun to new Denial of Service attack that can be used against EDA- adopt the Event-Driven Architecture (EDA) to provide scalable based services. Our Event Handler Poisoning attack exploits web services. Though the Event-Driven Architecture can offer the most important limited resource in the EDA: the Event better scalability than the One Thread Per Client Architecture, Handlers themselves. its use exposes service providers to a Denial of Service attack that we call Event Handler Poisoning (EHP). The source of the EDA’s scalability is also its Achilles’ heel. Multiplexing unrelated work onto the same thread re- This work is the first to define EHP attacks. After examining EHP vulnerabilities in the popular Node.js EDA framework and duces overhead, but it also moves the burden of time sharing open-source npm modules, we explore various solutions to EHP- out of the thread library or operating system and into the safety. For a practical defense against EHP attacks, we propose application itself. Where OTPCA-based services can rely on Node.cure, which defends a large class of Node.js applications preemptive multitasking to ensure that resources are shared against all known EHP attacks by making timeouts a first-class fairly, using the EDA requires the service to enforce its own member of the JavaScript language and the Node.js framework. cooperative multitasking [89]. An EHP attack identifies a way to defeat the cooperative multitasking used by an EDA-based Our evaluation shows that Node.cure is effective, broadly applicable, and offers strong security guarantees. -

Industrial Ethernet Quick and Simple Explanation of Key Terms
Industrial Ethernet Quick and simple explanation of key terms EN_Bro_Glossar_Netzwerktechnik_A6_Rev02.indd 1 26.05.14 15:26 Industrial Ethernet The use of industrial Ethernet communication offers many advantages and is becoming more common in the automation of production plants and machinery. Many new technical terms from the IT world are also being used in this context among industrial users. In this glossary, we have listed and explained the main techni- cal terms from the field of Industrial Ethernet – we make Ethernet easy. 2 PHOENIX CONTACT EN_Bro_Glossar_Netzwerktechnik_A6_Rev02.indd 2 26.05.14 15:26 Table of contents Glossary Pages 04 – 45 IEEE standards Pages 46 – 47 PHOENIX CONTACT 3 EN_Bro_Glossar_Netzwerktechnik_A6_Rev02.indd 3 26.05.14 15:26 Industrial Ethernet 10Base-T Standard for data transmission of 10 Mbps Ethernet using unshielded twisted pair cables (Category 3, 4 or 5). 100Base-FX Standard for data transmission of 100 Mbps Ethernet using fiber optic cables. 100Base-TX Standard for data transmission of 100 Mbps Ethernet using twisted pair cables (Category 5). Each connection is established via two wire pairs, one wire pair for “transmit data” and the other for “receive data”. 100Base-T Fast Ethernet; 100Base-T has been officially elevated to an IEEE standard as ITU 802.3u. This standard is essentially based on technologies for 10Base-T, the Ethernet version for twisted pair cables. There are several versions of 100Base-T, which differ with respect to the physical layer and therefore the transmission media: 100Base-TX, 100Base-T2, 100Base-T4, and 100Base-FX. With this method, the MAC level and therefore the conventional CSMA/CD access method are retained at a transmission speed of 100 Mbps. -

A food truck In its simplest form, Node is a set of libraries for writing high- operating like a traditional performance, scalable network programs in JavaScript. Take a synchronous web server look at this application that will respond with the text “Hello would have a worker take world!” on every HTTP request: an order from the first customer in line, and then // require the HTTP module so we can create a server object the worker would go off to var http = require(‘http’); prepare the order while the customer waits at the window.

Contrast this with a food truck operating like an asynchronous var helloServer = http.createServer(function (req, res) { web server. The workers in this truck would take an order from // send back the response headers with an HTTP status the first customer in line, issue that customer an order number, // code of 200 and an HTTP header for the content type res.writeHead(200, {‘Content-Type’: ‘text/plain’}); and have the customer stand off to the side to wait while the order is prepared. -

Store numeric time-series data 2. Render graphs of this data on demand What Graphite does not do is collect data for you, however there are some tools out there that know how to send data to graphite. Even though it often requires a little code, sending data to Graphite is very simple. 1.2 About the project Graphite is an enterprise-scale monitoring tool that runs well on cheap hardware. It was originally designed and written by Chris Davis at Orbitz in 2006 as side project that ultimately grew to be a foundational monitoring tool. In 2008, Orbitz allowed Graphite to be released under the open source Apache 2.0 license.
