The telephony industry was late to adopt open-source software and commodity protocols. The open-source development community is rapidly correcting that problem. Everyone from enthusiasts to Fortune 500 companies are now deploying open-source telephony software, from PBX's to voice messaging systems to VoIP gateways. This lecture will focus on the practical. We'll provide demos of the major open-source telephony systems, a brief tutorial on ....
Ten years ago hacking was a frontier; ten years from now, hacking will be embedded in everything we do, defined by the context in which it emerges. Real hackers will be pushing the frontiers of information networks, perception management, the wetware/dryware interface, and the exploration of our galactic neighborhood. Mastery means not only having the tools in your hands but knowing that you have them ... and using them to build the Big Pic..

The presentation will describe the inner workings of the Trojan "Setiri". Setiri leads a new wave of Trojan Horse technology that defeats most conventional security devices including personal firewalls, NAT, statefull inspection firewalls, IDS, proxy type firewalls and content level checking. The presentation will focus on the setting up of a bi-directional communication stream in non-conducive environments, rather than describing the featu....

This research is targeted at demonstrating that small amounts of data can be dispersed over IP based networks, utilizing the data payloads of existing protocols. Such data is expected to be kept alive on the ether until one chooses to retrieve it. The crux of the scheme is the fact that this type of data dispersal is expected to be extremely difficult to detect. Such a scheme also raises some very interesting aspects regarding using Interne....

The vulnerability reporting process is rife with competing interests. Research is conducted by software vendors themselves, paid consultants, government agencies, professional and academic researchers, as well as people who make their living in other ways. Each of these groups have particular interests in the process. The vendor of the targeted software has their concerns. The public at large has an interest in the process (and its results)....

FreeBSD security fundamentals will cover some security basics as well as advanced topics on FreeBSD host and network security. Emphasis will be on hardening a FreeBSD machine from the inside-out, locking down ports, services, filesystems, network activity, etc. Some of the material presented in this talk will be BSD-agnostic, and some will apply to a UNIX environment in general. Review of several recent UNIX security vulnerabilities and val....

Many people are interested in bringing their local underground community closer together by organising meetings for those in the area. While this is certainly a good idea, doing it successfully is not as simple as it sounds. Grifter (Salt Lake City 2600) and skroo (Los Angeles 2600) intend to cover the more relevant points of starting local meetings. Topics discussed will include identifying if your area needs a meeting, setting things..

Wireless communication devices have traditionally been exclusively hardware in nature. Software has augmented and is now replacing basic functional elements of radio systems. The conclusion of this process is a radio where almost all functions are performed by software. GNU Radio is a collection of software that when combined with minimal hardware, allows the construction of radios where the actual waveforms transmitted and received are def..

This talk will cover using the LOOP-AES package to encyrpt data on a removable, USB hard disk in linux. The presentation will focus on using encryption to protect your data, via using GNUPG, removable keychain, and a removable hard disk, to encrypt your home directory. It will focus on how to install the USB device, include a script for getting things going "automagically", and installing the LOOP-AES patch to both a stock and a custom....

Until now, the focus of Information Security within organisations was mainly technical. Organisations are becoming more and more aware of the fact that this technical side - although very important - is just one part of the total security solution. Currently, organisations are increasingly changing their focus to the organisational side of Information Security. In order to control the organisational issues of Information Security, an organi....

Joe Burton will discuss the events that lead to Dmitry's arrest last July in Las Vegas for violating the DMCA. Joe will also discuss the legal issues surrounding the case, the current status of the criminal proceedings in California and some thoughts on the future of the DMCA. Joe has been one of the nation's leading critics of the aggressive civil and criminal application of the DMCA's anti-circumvention provisions. Bill Reilly will discus....
Wireless has become quite popular in network scenarios from the basic home network to the corporate LAN to the point-to-point backbone tying together offices or job sites. Wireless security and security breaches have been getting lots of press as have various vendors' multitude of proposals for cute proprietary ways to solve some of the problems in currently available products (primarily 802.11) by retrofitting them with better encryption, ....

It's time to face the facts. While the game is progressing at an incredible pace, it's not going to be ready by January 9, or even the end of January. So, I guess I failed to meet my deadline. But! I'm not giving up. I'll still be releasing regular updates, and especially once the multiplayer lobby server is set up, things will start getting a lot more polish. My new goal will be to finish the game before school lets out for the summer. O..
DC Phone Home (DreamCast Phone Home, a pun on the well-known film ET: The Extraterrestrial) is a project that challenges conventional enterprise security models by showing the ease by which an attack to an organization's network resources and infrastructure can be performed from an internal perspective. Simply put, once the DreamCast is deployed, it 'phones home' joining an organization's internal network with a remote network. We show that....

A lovely, albeit slightly chilly, start to 2010 with the Grupetto this morning. About 90km out to Windsor and back to London on one of our normal training routes. Mark also kindly took some photos , a few of which feature me. Lots more similar rides to come whilst training for Paris-Roubaix and the Tour of Flanders. Happy New Year!

It was fun doing this last year. So I thought I would have another go at it and see what I come up with.
After seeing some of the great examples of coders working on practiced problems on KataCasts, I decided to try make my own. I am not happy with the pacing of the video. I’m about a minute too early relative to the music. But I thought I’d post the video here, to see what you all think. Comments are welcome! I hope the video will demonstrate how to use refactoring effectively to drive the design of a program.
For all network deployments, there is a requirement to present information relating to both topology, and various utilisation statistics to some human operator. In many cases, this process has become so ingrained in network requirements that there are almost ubiquitous solutions to the visualising data - for example, link utilisation is almost always presented via some framework or tool powered by RRDTool . Other tools, such as network "we..

NULL is not zero! - tanelpoder.com - 16 years ago - eng
Some time ago I wrote a post about how COUNT(*) and COUNT(column) are semantically different things ( link ). Such queries may return different results if the column counted has NULLs in it. And the difference comes from that NULL is not a value, it’s rather a state which says “value unknown” or “no value entered”. So, you better understand how NULLs interact with your SQL constructs if you call yourself a DBA or a database developer ;-)

SafeWeb is an encrypted (SSL) anonymous proxy service, used approximately 100 million times per month by hundreds of thousands of people worldwide. Triangle Boy is an Open Source program that lets volunteers turn their PCs into entry points into the SafeWeb network, thereby foiling censorship in countries like China and Iran. Triangle Boy uses IP spoofing and innovative packet routing to minimize the load on volunteer machines. I discuss Sa....

HavenCo provides secure colocation in the Principality of Sealand, in the North Sea, to a wide range of clients. We've gotten a lot of press in the past year, still, we get a lot of questions: # Why do people go offshore in the first place? # What can they gain? # Aren't they all just software pirates and pornographers? # Can existing companies restructure offshore after they get sued? # What is life like on Sealand....
