Understanding Linux Network Internals. The Linux Networking Architecture – Design and Implementation of Network Protocols in.
The original development tools used for building both Linux applications and operating system programs are found within the GNU toolchain, which includes the GNU Compiler Collection (GCC) and the GNU Build System. Amongst others, GCC provides compilers for Ada, C, C++, Go and Fortran. BASIC in the form of Visual Basic is supported in such forms as Gambas, FreeBASIC, and XBasic, and in terms of terminal programming or QuickBASIC or Turbo BASIC programming in the form of QB64. First released in 2003, the LLVM project provides an alternative cross-platform open-source compiler for many languages. Many programming languages have a cross-platform reference implementation that supports Linux, for example PHP, Perl, Ruby, Python, Java, Go, Rust and Haskell. Linux distributions support dozens of programming languages. Proprietary compilers for Linux include the Intel C++ Compiler, Sun Studio, and IBM XL C/C++ Compiler.
GameOver Zeus represents one of the most complex, and successful, law enforcement operations against cyber crime to date. This presentation will detail many of the individuals responsible for GameOver Zeus and Cryptolocker, summarize the law enforcement investigation, and highlight the novel legal processes used to wrest control of the botnet from its operators. The talk will highlight extensive industry and government partnerships, the many international agencies that played a part, and discuss some of the methods used by private industry and law enforcement personnel to track and identify those responsible for the malware. The investigation resulted in the highest ever reward offered for a cyber criminal: ,000,000 for Evgeniy Bogachev.
Although the complete source code of MINIX was freely available, the licensing terms prevented it from being free software until the licensing changed in April 2000. MINIX was created by Andrew S. Tanenbaum, a computer science professor, and released in 1987 as a minimal Unix-like operating system targeted at students and others who wanted to learn the operating system principles.

Has anyone wondered if the files they share on the cloud are really safe/private. This talk is all about demonstrating that by a high chance they aren’t, as long as determined and patient attackers can try guessing or bruteforcing the not-so-random IDs of the automatically created filenames for these services.

Linux Kernel Internals Training. Course Overview This course on Linux Kernel training is a mandatory course for anyone planning to learn Linux Kernel.
We conclude with proposals to answer the lingering question of whether there is a solution that does not weaken encryption systems or mandate technological designs while still enabling limited government access to secure communications. We provide a background on end-to-end encryption, a techno-political history of backdoors, and an update on the current state of affairs. Current proposals, such as key escrow, split-key systems, and account mirroring, are complicated and difficult to implement securely. We explore various options for working around end-to-end encryption, focusing on implementation details and potential weakness due to administrative failure in procedures to request and obtain access and technical attacks on the implementation. Governments fear going dark with encryption hindering criminal and national security investigations. Privacy advocates have opposed backdoors since the 1990s and the battle is heating up again, this time on a global scale. Backdoors have also been criticized as making systems inherently less secure. Governments are demanding backdoor access to encrypted data – particularly on mobile devices and in the cloud – as strong encryption becomes commonplace.

 Android is also a popular operating system for tablets, and Android smart TVs and in-vehicle infotainment systems have also appeared in the market. Android has become the dominant mobile operating system for smartphones, running on 79. 3% of units sold worldwide during the second quarter of 2013.
The GSoC/Ncrack Presentation slides are a brief overview of the subjects that were discussed during the lecture. I recently gave a talk at a local linux user group about my involvement with Google Summer of Code 2009 and some of the technical aspects of the project I undertook: Ncrack.
The funniest part about the whole thing was the fact that I needed to change the Linux kernel source code, so that I could make packets of arbitrary length (packets that had an overall real length that was less than the one mentioned in the ip->ip_len field in the IP header). It was part of the inspection I would do anyway for the upcoming paper. I’ve been busy lately, dealing with many tenuous projects, but managed to indulge myself by auditing some of the Nmap code. So, I applied this set of checks upon the latest Nmap release validation routines. The result was this. The chapter on networks, mentioned a list of basic rules that every low-level network tool should follow as far as packet length validation is concerned. The idea came while revisiting some chapters from the venerable security bible “The art of software security assessment”.
