Multi-Player Metasploit: Tag Team Pen Testing and Reportingsussurro
This presentation discusses how database components of Metasploit can be used through XMLRPC to facilitate pen testing data sharing and collection in order to ensure real time actionable information is available to all testers at all times.
25. Microsoft HTC Introduced in Microsoft® Internet Explorer 5, HTML Components (HTCs) provide a mechanism to implement components in script as Dynamic HTML (DHTML) behaviors.
43. Script Dom Element 使用ScriptDomElement解决脚本阻滞问题 function scriptDomElement(u) { var s = document.createElement('script'), h = document.getElementsByTagName('head')[0]; s.src= u; s.async= true; if(h)h.insertBefore(s,h.firstChild); } 通过Dom方法创建一个script节点,并插入到文档当中. 在各种浏览器中这种方式都能保证脚本与其他资源并行下载.
53. 更通俗的例子 var result = db.query("select.."); // use result either blocks the entire process or implies multiple execution stacks. db.query("select..", function (result) { // use result }); allows the program to return to the event loop immediately.
55. NodeJS Node's goal is to provide an easy way to build scalable network programs. many client connections can be handled concurrently. Node tells the operating system (throughepoll, kqueue, /dev/poll, or select) that it should be notified when a new connection is made, and then it goes to sleep. If someone new connects, then it executes the callback. Each connection is only a small heap allocation.
60. 事件驱动中的状态保持 function main(){ var name = "limu"; var age = db.query("selectage from person where name="+name); print("the age of" + name + "is" + age); } print("query start"); main(); print时变量name和age同时可用.
61. 事件驱动中的状态保持 function main(){ var name = "limu"; db.query("selectage from person where name="+name, function(age){ print("the age of" + name + "is" + age); } ); } main(); print("query start"); 假设查询耗时3秒,3秒后执行回调函数.print时age可用. 而一般而言name作为main函数的局部变量已经出了其作用域范围而被销毁. 如果想继续用name变量需要额外的保存动作,即状态保持.
62. CFO 体系 Understanding this strong relationship between objects, functions, and closures will improve your JavaScript programming ability giving you a strong foundation for any type of application development.
63. 基于闭包的状态保持 function (socket) { socket.addListener("data", function (data) { //10s之后data到达本函数运行 //为什么可以访问socket socket.write(data); } ); } 闭包:function在生成时会保存所有当时可访问变量的引用,以备函数运行时使用.
64. CommonJS:JS想成为服务端语言还缺什么 Modules Binary strings and buffers Charset encodings Binary, buffered, and textual input and output (io) streams System process arguments, environment, and streams File system interface Socket streams Unit test assertions, running, and reporting Web server gateway interface, JSGI Local and remote packages and package management CommonJS是一种规范,NodeJS是这种规范的部分实现之一。
