Gene Kim is one of the original authors of Tripwire, a software product used to manage configurations and change. Gene is willing to share his thoughts on virtualization with the Security Laboratory thought leadership series, and we certainly thank him for his time!

Imperva and a few other vendors are starting to understand the importance of database security and release product, but Kevin Kenan, Managing Director, K2 Digital Defense picked up on this long ago.

Perhaps, one of the hottest topics in 2008 is log file analysis (who would have guessed). And while the commercial tools are getting a lot of the press, an open source and also commercial tool is ending up on a lot of systems. It is called Snare and Leigh Purdie is the thought leader behind the project. He has been willing to invest the time for a thought leadership interview with the Security Laboratory

I keep thinking about the news reports that Chinese hackers managed to exfiltrate six terabytes of sensitive data from a large number of systems belonging to the Department of Homeland Security in November 2007. It seems like that would be impossible to do without being detected. But, I have to wonder, since the famous Richard Stiennon paper, Intrusion Detection is Dead, organizations have been replacing IDS with IPS, and maybe, just maybe, they think the devices do their job in some kind of "fire and forget" mode. Sourcefire was kind enough to allow me to interview Snort creator and Sourcefire CEO Marty Roesch on this topic.

Dr. Anton Chuvakin from LogLogic is probably the number one authority on system logging in the world, and his employer is probably the leading vendor for logging, so we appreciate this opportunity to share in his insights.

One of the ongoing research projects in the Security Laboratory is to work with the thought leaders in information security to get an understanding of their vision for our industry. We have recently had the honor of working with Kishore Kumar, CEO of Pari Networks, and we certainly thank him for his time.

The Leadership lab came across an interesting company, Itiva. Their CTO, Dr. Robert Arn, was kind enough to share his time and thoughts with our readers, and we certainly thank him for his time.

Charles Edge talks with Stephen Northcutt about security issues in the Mac world; even though the core OS is pretty safe, there are vulnerabilities that every Mac user should be aware of.

Stephen Northcutt interviews Mike Weider, CTO of Watchfire, regarding recent trends in web app vulnerabilities as well as his company's solutions for web application security.

The Leadership Laboratory recently posted a book review of The Art of Software Security Assessment. The book raises a number of issues that we would love to explore further and the authors, Mark Dowd, John McDonald and Justin Schuh have graciously agreed to an interview. One section was titled Code Auditing and the Development Life Cycle and we used that as the basis of the interview.

Ryan Barnett, Director of Application Security Training at Breach Security, Inc. talks with Stephen Northcutt about the current state of web application security.

Dinis Cruz, Director of Advanced Technology for Ounce Labs, talks with Stephen Northcutt about the many facets of OWASP, as well as the important questions that need real answers in order to develop secure web applications.

Brian Chess, Chief Scientist for Fortify Software, talks with Stephen Northcutt about static analysis and other web application security solutions.

Stephen Northcutt interviews Caleb Sima about the development of Caleb's company, SPI Dynamics, and the increasing need for solutions for web application security.

An interview with David Hoelzer describing DAD, an open source Windows event log and syslog management tool that allows you to aggregate logs from hundreds to thousands of systems in real time.

Ce qui est toujours plaisant lors de montée de version d’un outil, restera toujours la découverte des nouveautés  et ensuite … le recherche délicate des fonctions d’origine … sans parler des fonctions désormais absentes … A chaque migration, l’outil ...

Il est vraiment difficile d’arriver à suivre toutes les nouveautés et autres informations diverses et variés sur SharePoint et Office 2016, On peut passer à coté de certaines …pas d’une nouveauté mais plutôt d’une disparition, d’une feature deprecate...

The lower layers in the modern computing infrastructure are written in languages threatened by exploitation of memory management errors. Recently deployed exploit mitigations such as control-flow integrity (CFI) can prevent traditional return-oriented programming (ROP) exploits but are much less effective against newer techniques such as Counterfeit Object-Oriented Programming (COOP) that execute a chain of C++ virtual methods. Since these methods are valid control-flow targets, COOP attacks are hard to distinguish from benign computations. Code randomization is likewise ineffective against COOP. Until now, however, COOP attacks have been limited to vulnerable C++ applications which makes it unclear whether COOP is as general and portable a threat as ROP. This paper demonstrates the first COOP-style exploit for Objective-C, the predominant programming language on Apple’s OS X and iOS platforms. We also retrofit the Objective-C runtime with the first practical and efficient defense against our novel attack. Our defense is able to protect complex, real-world software such as iTunes without recompilation. Our performance experiments show that the overhead of our defense is low in practice.

Modeling relation paths has offered significant gains in embedding models for knowledge base (KB) completion. However, enumerating paths between two entities is very expensive, and existing approaches typically resort to approximation with a sampled subset. This problem is particularly acute when text is jointly modeled with KB relations and used to provide direct evidence for facts mentioned in it. In this paper, we propose the first exact dynamic programming algorithm which enables efficient incorporation of all relation paths of bounded length, while modeling both relation types and intermediate nodes in the compositional path representations. We conduct a theoretical analysis of the efficiency gain from the approach. Experiments on two datasets show that it addresses representational limitations in prior approaches and improves accuracy in KB completion.
