Cyber Protectionism: Global Policies are Adversely Impacting Cybersecurity SANS.edu Graduate Student Research
by Erik Avery - August 21, 2019Cyber Protectionist policies are adversely impacting global cybersecurity despite their intent to mitigate threats to national security. These policies threaten the information security community by generating effects which increase the risk to the networks they are intended to protect. International product bans, data-flow restrictions, and increased internet-enabled crime are notable results of protectionist policies – all of which may be countered through identifying protectionist climates and subsequent threat. Analyzed historical evidence facilitates a metrics-based comparison between protectionist climate and cybersecurity threats to comprise the Cyber Protectionist Risk Matrix - a risk framework that establishes a new cybersecurity industry standard.

Securing Against the Most Common Vectors of Cyber Attacks SANS.edu Graduate Student Research
by Richard Hummel - September 12, 2017Advanced Persistent Threat (APT) adversaries run highly targeted, multifaceted campaigns to exploit vulnerabilities either through holes in an organization's security implementation or by targeting the human element which often uses social engineering. Financially motivated actors indiscriminately send mass spam emails in credential harvesting campaigns or deploy ransomware. These attack vectors are the most common against organizations of any size, but often have a greater impact on small to medium-sized business that may not have a robust security posture. As a security practitioner, it is imperative to posture an organization to prevent and mitigate the risk posed by these attacks. The Critical Security Controls (CSC) is the industry standard for securing an environment but may be costly and time-consuming to implement; also, some of them may not be as applicable to all organizations. In this study, the controls for Email and Web Browser Protection (#7) and Security Skills Assessment and Appropriate Training to Fill Gaps (CSC #17) are examined to secure against threats seeking to take advantage of end users, the most common entry point for an attacker. This paper examines multiple real-world threats and how the CSCs can be applied to prevent compromises. The goal of this research is to inform and educate security practitioners at any stage of the business on best practices and to aid in implementing controls directly applicable to their end users.

A Black-Box Approach to Embedded Systems Vulnerability Assessment by Michael Horkan - December 5, 2016
Vulnerability assessment of embedded systems is becoming more important due to security needs of the ICS/SCADA environment as well as the emergence of the Internet of Things (IoT). Often, these assessments are left to test engineers without intimate knowledge of the device's design, no access to firmware source or tools to debug the device while testing. This gold paper will describe a test lab black-box approach to evaluating an embedded device's security profile and possible vulnerabilities. Open-source tools such as Burp Suite and python scripts based on the Sulley Fuzzing Framework will be employed and described. The health status of the device under test will be monitored remotely over a network connection. I include a discussion of an IoT test platform, implemented for Raspberry Pi, and how to approach the evaluation of IoT using this device as an example.

Ransomware by Susan Bradley - October 3, 2016
On a daily basis, a file gets clicked. An email attachment gets opened. A website gets browsed. Seemingly normal actions in every office, on every personal computer, can suddenly become a ransomware incident if the file or attachment or banner ad was intended to infect a system and all files that the user had access to by ransomware. What was once a rare occurrence, now impacts networks ranging from small businesses to large companies to governments.

Filling the Gaps by Robert Smith - August 18, 2016
There should be an emphasis on the importance of regular internal and external auditing focusing on the business mentality of "It can't happen to me" and mitigating the risk of complacency. The key areas covered will be cementing assessments and audits as a benefit versus a reactive or troublesome activity. The cost savings from regular auditing against the alternatives such as breaches and poor publicity. The world is full of technical and administrative compliance requirements, understanding where gaps are present is not something to be afraid of, but to readily embrace and act upon those deficiencies. Thinking that you are compliant and knowing you are compliant can make a large difference in business longevity and profitability.

How to Target Critical Infrastructure: The Adversary Return on Investment from an Industrial Control System SANS.edu Graduate Student Research
by Matthew Hosburgh - July 12, 2016Imagine a device that could decrypt all encryption—within seconds. A box with this capability could be one of the most valuable pieces of equipment for an organization, but even more valuable to an adversary. What if that box only worked against American encryption? If true, a particular market would be ripe for the harvest. A device that powerful could be used to decrypt secrets and data in transit, making encrypted data an adversary might have access to, extremely valuable. Similarly, Critical Infrastructure is a target for some because of the yield that a successful attack could result in. Death, disruption or damage is a real possibility. The Return on Investment (ROI) and Return on Security Investment (ROSI) fall short in actually determining the level of protection required for an organization striving to protect the most sensitive data or system. The Adversary Return on Investment (AROI) is the missing piece to the equation. From the adversary’s vantage point, data, infrastructure or systems have value. By understanding this value an organization can more appropriately align its security strategy; especially, for the most critical infrastructure.

Measuring Psychological Variables of Control In Information Security by Josh More - January 12, 2011
“Perceived Control” is a core construct used in the psychology field that can be considered an aspect of empowerment (Eklund, & Backstrom, 2006). Effectively, it is a measure of how much control people feel that they have, as opposed to the amount of “Actual Control” that they may have. It is often paired against constructs such as “Vicarious Control” and “Vicarious Perceived Control”, which measure the amount of control that outside entities have over the subject. Often, these are variables measured in the psychology/health field. For example, in the world of medicine, when patients report a lack of perceived control over controllable illnesses such as diabetes (Helgeson, & Franzen, 1997), breast cancer (Helgeson, 1992) and heart disease (Helgeson, 1992), they often do more poorly than patients who feel that they have a greater sense of control over their illness. There is also evidence that students with high perceived control do substantially better academically than those with low, though this seems to also link with emotions surrounding the tasks at hand (Ruthig, Perry, Hladkyj, Hall, & Pekrun, 2008). In short, people who are interested in and excited by what they are doing tend to perform better.

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.

A Question of Platinum Plus by Craig Wright - December 29, 2010
The fallacy of the black swan in risk has come full circle in information systems. Just as the deductive fallacy, “a dicto secundum quid ad dictum simpliciter2” allowed false assertions that black swans could not exist when they do, we see assertions that risk cannot be modeled without knowing all of the „black swans‟ that can exist. The falsity of the black swan argument derives from a deductive statement that “every swan I have seen is white, so it must be true that all swans are white”. The problem is that which one has seen is a subset of the entire set. One cannot have seen all swans.
