Creating a Threat Profile for Your Organization
by Stephen Irwin - October 2, 2014
Developing a detailed threat profile, provides organizations with a clear illustration of the threats that they face, and enables them to implement a proactive incident management program that focuses on the threat component of risk. Organizations are facing new types of advanced persistent threat (APT) scenarios that existing risk management programs are not able to evaluate completely and incident management programs are not able to defend against. This paper provides information about how to expand existing risk management models to better illustrate APTs and provides a framework on how to gather threat related information so that detailed threat profiles that include APTs can be developed for organizations.

Reducing Organizational Risk Through Virtual Patching
by Joseph Faust - January 11, 2011
Software patching for IT Departments across the organizational landscape has always been an integral part of maintaining functional, usable and stable software. Historically the traditional patch cycle has been focused on fixing or resolving issues which affect functionality. In recent years, with the advancement of more sophisticated and targeted threats which are occurring in quicker cycles, this focus is dramatically changing. (Risk Assessment Cisco, n.d.; Executive Office of The United States, 2005) . Corporations and Government now have a greater understanding of potential losses and expenses incurred by not maintaining application security and are moving towards an increased focus on patching and security (Epstein, Grow & Tschang, 2008). With organizations reputations, consumer confidence and corporate secrets at risk, corporations and government are recognizing the need to shift and address vulnerabilities at a much faster pace than they historically have done so (Chan, 2004). Over roughly the last ten years, the length of time between the documentation of a given vulnerability in a piece of software and the development of an actual exploit that can take advantage of the weakness in the application, has decreased tremendously. According to Andrew Jaquith, senior analyst at Yankee Group, the average time between vulnerability discovery and the release of exploit code is less than one week. (Shrinking time from, 2006). It has also been identified that 99% of intrusions result from exploitation of known vulnerabilities or configuration errors where countermeasures were available ("Risk reduction and.," 2010) . Clearly these statistics alone can prove daunting for many businesses trying to keep pace and maintain proper defenses against the bad guys.
Malicious Android Applications: Risks and Exploitation
by Joany Boutet - December 22, 2010
Android is an open-source mobile operating system, based upon a modified version of the Linux kernel, initially developed by Android Inc., a firm purchased by Google in 2005. A Gartner study released on November 2010 outlined that Android has become the second-most popular OS in the world (Gartner, 11/2010). The growth of Android has exceeded their previous study, released last year, in which they had predicted that Android will be the No.2 worldwide mobile operating system in 2012 (The H, 08/10/2009). According to another Gartner study (Gartner, 08/2010)., there will be only a slight difference between Symbian and Android market share in 2014: 30.2% for Symbian against 29.6% for Android.

Threat Analysis of Allowing Employee Internet Access
by Mason Pokladnik - March 28, 2008
The ISO 17799/27001 standard provides a good minimum description of what organizations should be doing to protect themselves, but it should not be the sole focus of your security and audit control design. A better approach is to allow your information-security management-system subcommittees or technical specialists to analyze the threats your organization is likely to face. Then, design your controls around those threats, balancing the cost to mitigate a threat versus the cost of a threat occurring in your environment. Finally, after you have analyzed the threats, you can double check your policies and procedures against a regulatory or management framework, such as ISO17799, SOX, GLBA, HIPPA or PCI.
Attack vs. Defense on an Organizational Scale
by Omar Fink - December 11, 2007
Historically, the motivation behind most cyber attacks was similar to graffiti, in that the main purpose was to make a mark on somebody elses territory, to demonstrate technical skill by compromising a web server and defacing the main page, with the primary goal seeming to be simply to make a statement of existence. In recent years, this has evolved to being more concerned about making a profit or creating a political impact.
ANI vulnerability: History repeats
by Shashank Gonchigar - October 24, 2007
Animated cursors (.ani files) are used to change the appearance of the mouse pointer to an animation. Common example would be Mouse pointer turning into hour glass when the processor is busy. In the month of March 2007 a quite severe vulnerability was announced. It was subsequently exploited because of a flaw in the code which handled these files. This paper is a discussion about the ANI header buffer overflow vulnerability (Microsoft Security Bulletin MS07-017 - CVE-2007-0038). As we progress, we will understand what caused this vulnerability, analyze an exploit (PoC), understand the heap spraying technique employed by this exploit and finish with the incident handling process.
A System of Persistent Baseline Automated Vulnerability Scanning and Response in a Distributed University Environment
by Chet Langin - September 18, 2007
This paper describes and analyzes a persistent automated baseline vulnerability scanning procedure in a university (The University), including preparation, response, and follow up procedures.
