FreeSWITCH | Communication Consolidation Scanning the Internet with Nmap (Defcon 16) Tutorial Scanning The Internet With Nmap (Defcon 16) Description: How would you like to scan millions of hosts on the Internet and catalog all the interesting insights? This is exactly what Fyodor, the author of Nmap or Network Mapper did last summer. In this talk Fyodor demos many of the new features he has added in Nmap lately including but not limited to - optimizing the host discovery process using TCP and UDP techniques, finding most used TCP and UDP ports on the Internet and inside Intranets of large corporations, packet rate control with a minimum and maximum setting, the pack trace option, ncat - which is a netcat clone and ndiff which allows one to diff between different scan dumps. The slides for the presentation are available here and a high resolution video can be downloaded here. Disclaimer: We are a infosec video aggregator and this video is linked from an external website.
Open Port Check Tool OpenVAS - OpenVAS - Open Vulnerability Assessment System Community Site ShieldsUP! — Internet Vulnerability Profiling Your Internet connection's IP address is uniquely associated with the following "machine name": The string of text above is known as your Internet connection's "reverse DNS." The end of the string is probably a domain name related to your ISP. This will be common to all customers of this ISP. But the beginning of the string uniquely identifies your Internet connection. The concern is that any web site can easily retrieve this unique "machine name" (just as we have) whenever you visit. If the machine name shown above is only a version of the IP address, then there is less cause for concern because the name will change as, when, and if your Internet IP changes. There is no standard governing the format of these machine names, so this is not something we can automatically determine for you. Just something to keep in mind as you wander the Internet.

Customize an HTML5 Webpage using the Bootstrap Framework Many web developers are familiar with Twitter Bootstrap and have seen this library on a number of projects. The Bootstrap core is fantastic when you need a CSS reset along with other common layout features. It may not be the right fit on projects where you need a whole lot of customization. Downloading Bootstrap Right from the hosted Github project page you should be able to download a copy of Bootstrap. I will also be using the two minified CSS documents named bootstrap.min.css and bootstrap-responsive.min.css. The HTML5 doctype is the best supported option for modern browsers. Heading Navigation Bar Directly after the opening body tag I have setup a fixed navigation menu. The header div contains another bit of code with a container and the class .text-center. All of this code is stored inside my own custom stylesheet global.css. Flexible Columns Underneath the fullscreen background image I have created a centered main content area.

PsExec Introduction Utilities like Telnet and remote control programs like Symantec's PC Anywhere let you execute programs on remote systems, but they can be a pain to set up and require that you install client software on the remote systems that you wish to access. PsExec is a light-weight telnet-replacement that lets you execute processes on other systems, complete with full interactivity for console applications, without having to manually install client software. PsExec's most powerful uses include launching interactive command-prompts on remote systems and remote-enabling tools like IpConfig that otherwise do not have the ability to show information about remote systems. Note: some anti-virus scanners report that one or more of the tools are infected with a "remote admin" virus. Installation Just copy PsExec onto your executable path. Using PsExec See the July 2004 issue of Windows IT Pro Magazine for Mark's article that covers advanced usage of PsExec. psexec \\marklap"c:\long name app.exe"
Introducing HTML’s new template element You may have heard of Web Components, a suite of emerging standards that make it possible to build secure reusable widgets using web platform technologies. One of the first specs to make its way into implementation is HTML Templates, embodied by the template element, which as I write this is implemented in Chrome Canary and Firefox Nightly. If you've used Mustache, Handlebars or any similar front-end templating library you'll be quite familiar with how the template element works: you just include it in your document (it's apparently legal inside head or body), perhaps with a unique id for easy reference and add some markup inside it; for example: The template element will be parsed by the browser but not rendered in the page; the markup inside is considered completely inert, meaning no style rules will be applied and no assets loaded. In order to use the template markup you'll need to activate it by placing it into the DOM using JavaScript. View Demo
NetworkMiner - The NSM and Network Forensics Analysis Tool NetworkMiner is a Network Forensic Analysis Tool (NFAT) for Windows (but also works in Linux / Mac OS X / FreeBSD). NetworkMiner can be used as a passive network sniffer/packet capturing tool in order to detect operating systems, sessions, hostnames, open ports etc. without putting any traffic on the network. NetworkMiner can also parse PCAP files for off-line analysis and to regenerate/reassemble transmitted files and certificates from PCAP files. NetworkMiner makes it easy to perform advanced Network Traffic Analysis (NTA) by providing extracted artifacts in an intuitive user interface. The way data is presented not only makes the analysis simpler, it also saves valuable time for the analyst or forensic investigator. NetworkMiner has, since the first release in 2007, become a popular tool among incident response teams as well as law enforcement.

HTML5 Tutorial - Welcome Computer acting funny? It may be infected with a virus! One great thing about computers is that they often warn us when something is wrong. Sometimes they suddenly slow down to a crawl, other times they start to freeze up or even crash for what seems to be no reason at all. Most of the time though, there is a reason why our computers start to act funny. One of those reasons is due to malware and viruses. No one likes to have a computer virus, but if you do happen to catch one, it’s important to know the warning signs so that you can take care of the problem as soon as possible. If you have noticed one or more of the above symptoms on your computer, it’s time to take immediate action. Be sure to share this infographic so that others can benefit as well.
