Bill Gates and Trustworthy Computing: A Case Study in Transformational Leadership by Preston S. Ackerman - September 20, 2016
The notion that IT security is a serious issue is non-controversial. The market for cybersecurity spending topped $75 billion in 2015, and analysts expect it to exceed $170 billion by 2020 (Morgan 2016). With the advent of cloud computing, the explosion of mobile devices, and the emergence of increasingly sophisticated adversaries from organized crime and nation-state actors, businesses and the industry as a whole will require the vision of great leaders to keep pace with the threats. We can look to the industry's rich history to see examples of such transformational leadership in the past. An enlightening case study is the Microsoft Trustworthy Computing initiative, launched by an insightful and stimulating memo Bill Gates sent on January 15, 2002. The initiative would not only transform culture, procedures, and policy surrounding security at Microsoft, but would in fact cause a dramatic shift for the entire industry. The idealized influence in the leadership shown by Gates can serve as a model for today's leaders.

Case Study: The Home Depot Data Breach STI Graduate Student Research
by Brett Hawkins - October 27, 2015The theft of payment card information has become a common issue in today's society. Even after the lessons learned from the Target data breach, Home Depot's Point of Sale systems were compromised by similar exploitation methods. The use of stolen third-party vendor credentials and RAM scraping malware were instrumental in the success of both data breaches. Home Depot has taken multiple steps to recover from its data breach, one of them being to enable the use of EMV Chip-and-PIN payment cards. Is the use of EMV payment cards necessary? If P2P (Point-to-Point) encryption is used, the only method available to steal payment card data is the installation of a payment card skimmer. RAM scraping malware grabbed the payment card data in the Home Depot breach, not payment card skimmers. However, the malware would have never been installed on the systems if the attackers did not possess third-party vendor credentials and if the payment network was segregated properly from the rest of the Home Depot network. The implementation of P2P encryption and proper network segregation would have prevented the Home Depot data breach.

DevOps Rescuing White Lodging from Breaches STI Graduate Student Research
by Tobias Mccurry - August 18, 2015For the second time in fourteen months, multiple financial institutions lodged complaints of fraud on customer credit and debit cards recently used at White Lodging Services’ locations (Krebs, Hotel Franchise Firm White Lodging Investigates Breach, 2014). White Lodging, along with others, was attacked to gain access to the highly profitable credit card data in their financial systems. Companies are faced with the threat of many different malware specialized in Point of Sale systems. This paper will take a case study approach to examine the White Lodging breaches and show how adopting the Development Operations (DevOps) mindset could have worked to mitigate the breaches. This approach can provide an organization a systematic method to quickly implement the Sans Critical Controls.

Following a Breach Simulating and Detecting a Common Attack STI Graduate Student Research
by Dale Daugherty - August 14, 2015Modern networks are designed with multiple layers of preventive and detective controls. Even with these controls, networks continue to be breached and these breaches can go unnoticed for months. While preventive measures cannot stop all attacks and exploits, detective measures should be able to identify intrusions and malicious activity in a timely manner. The ability to detect this activity depends on the kinds of intrusion monitoring systems in place and the analysts’ ability to recognize and act on the alerts. This paper will outline the anatomy of a common attack, simulate the steps in an attack; including elements from the recent breach of Sally Beauty Supply, and determine how an attack can be detected.
-
Data Loss Prevention and a Point of Sales Breach STI Graduate Student Research
by Nicholas Kollasch - August 10, 2015Target could have used a data loss prevention solution to mitigate the success of its infamous data breach. However, organizations typically deploy data loss prevention with simple policies and rules that detect 15- or 16-digit number strings that might represent a credit card number; this strategy, would not be effective in the case of the Target attack due to the attackers packaging the “loot” with Base64 encoding directly on the point of sales systems. Therefore, a security practitioner requires alternative detection measures to detect this type of anomalous activity. Data loss prevention can support an organization’s ability to implement the Critical Security Controls, thereby providing the capability to detect such a sophisticated attack during the key stage of the Kill Chain model: Actions on Objective. Data loss prevention, when implemented with robust rules that reflect current attack tactics, techniques, and procedures, can reduce the likelihood of success by making it a bit more difficult to extract the valuable data.

Creating Robust IT Security and Efficiency by Reducing Infrastructure Complexity in Higher Education by Keith Lard - November 17, 2010
Recent economic conditions have created a business problem unique to higher education and its IT infrastructure. In the past ten years, IT systems and infrastructure have experienced a rapid change in complexity as a result of moving from mainframes to web services (Weinschenk, 2003). The technical landscape continues to become more complex as technology advances and application sophistication increases more rapidly, creating a greater dependency on IT services. To stay competitive and efficient, private and for-profit businesses have spent the last ten years keeping up with technology and training their staff. However, the university has been insulated in its own microcosm, having the luxury of ignoring business cycles, as the product offered has not changed drastically. Now, recent economic conditions and rapid advancement in technology have created the perfect storm within the university setting.

Smart IDS - Hybrid LaBrea Tarpit by Cristian Ruvalcaba - December 28, 2009
The importance of IDS in corporate defense is seen as an ever growing necessity. Major strides have been made for numerous IDS tools, but some have seen a stalemate. The next evolutionary step in IDS would involve the concept of a 'Smart Intrusion Detection System (IDS)', one that generates signatures. The question of how to generate these signatures becomes instrumental, and can involve a number of different components. In this case, it could involve a tool that uses a hybrid LaBrea concept.

Effectiveness of Antivirus in Detecting Metasploit Payloads STI Graduate Student Research
by Mark Baggett - March 28, 2008Your neighbor stops you at your curb. He knows you‟re a computer security guru and wants to know the secret to protecting his computer from hackers. You need to get back to mowing the lawn and don‟t really have time to explain log monitoring, patch management, vulnerability assessments, penetration testing, least required access, the CIA triad, and the finer points of risk management. Besides, you know you’re the only guy on the block with syslog servers, hardware firewalls, IDS and HIPS watching the one computer in your house that you only use for online banking. So what do you tell him? “Keep your patches and antivirus software up to date and don‟t run untrusted programs”. You know it’s not enough, but any more advice would commit you to hours of free consulting or get you uninvited to the neighborhood Christmas party. “Don‟t run untrusted programs”…good advice! The problem is most people trust everyone when it comes to free software.
