The Jester Dynamic: A Lesson in Asymmetric Unmanaged Cyber Warfare STI Graduate Student Research
by Terrence OConnor - February 14, 2012 in Attacking Attackers, Information Warfare
We live in an era where a single soldier can digitally leak thousands of classified documents (possibly changing the course of war), attackers can compromise unmanned drone control software and intercept unencrypted video feeds, and recreational hackers can steal and release personal information from members of cyber think-tanks.
Securing the Home IoT Network STI Graduate Student Research
by Manuel Leos Rivas - April 5, 2017 in Network Access Control, Home & Small Office, Internet of Things
The Internet of Things (IoT) has proven its ability to cause massive service disruption because of the lack of security in many devices. The vulnerabilities that allow those denial of service attacks are often caused due to poor or no security practices when developing or installing the products. The common home network is not designed to protect against the design errors in IoT devices that expose the privacy of the users. The affordable price of single board computers (SBC) and their small power requirements and customization capabilities can help improve the protection of the home IoT network. SBC can also add powerful features such as auditing, inspection, authentication, and authorization to improve controls pertaining to who and what can have access. Implementing a home-control gateway when properly configured reduces some common risks associated with IoT such as vendor-embedded backdoors and default credentials. Having an open source trusted device with a configuration shared and audited by many experts can reduce many of the bugs and misconfigurations introduced by vendor security program deficiencies.

Security Operations Centers are increasingly important in today's enterprises - they protect against intrusions, damaging DDoS attacks and data security breaches, as well as help with investigation and remediation. But how can midsize enterprises get the same SOC advantages as their large enterprise peers?
This paper explores how Arctic Wolf Networks' CyberSOC can help midsize organizations roll out a SOC-as-a-Service, thereby leveraging the benefits of a SOC without the high costs of a DIY solution.
Detecting Attacks Against The 'Internet of Things' by Adam Kliarsky - March 30, 2017 in Intrusion Detection, Internet of Things
The need to detect attacks against our networks has exploded with the rapid adoption of connected devices affectionately dubbed the "Internet of Things" (or IoT). Manufacturers are rapidly producing devices to meet consumer and market demand which creates a shortened time-to-market in manufacturing. The level of security in the product development lifecycle becomes questionable, as well as production standards. Vulnerabilities have been showing up targeting the physical interfaces of IoT devices, wireless protocols, and user interfaces. It is imperative that intrusion analysts understand how to assess the attack surface, analyze threats, and develop the capability to detect attacks in IoT environments. This paper will review threats, vulnerabilities, attacks, and intrusion detection as it applies to the IoT.
Cyber Security Trends: Aiming Ahead of the Target to Increase Security in 2017 Analyst Paper
by John Pescatore - March 20, 2017 in Cloud Computing, Data Protection
- Associated Webcasts: 2017 Cybersecurity Trends: Aiming Ahead of the Target to Increase Security
Attackers are always changing their methods, but some cybersecurity trends are clear--and identifying these trends will help security professionals plan for addressing these issues in the coming year. Attacks will continue, and many will be successful. While security professionals should try to prevent a breach, it's far more critical to uncover breaches quickly and mitigate damage. Another significant trend for 2017: expanding current security measures to better protect data in the cloud and to address the security shortcomings of the Internet of Things. Even while fighting daily security fires, security managers can expect boards of directors to show more interest in their efforts. Board members are keenly aware that breaches can be high-profile catastrophes for companies, and they are also concerned that the organizations they oversee are in compliance with new and more stringent regulations. This whitepaper covers the latest and best security hygiene and common success patterns that will best keep your organization off the "Worst Breaches of 2017" lists.
Identifying Vulnerable Network Protocols with PowerShell STI Graduate Student Research
by David Fletcher - April 6, 2017 in Network Access Control
Microsoft Windows PowerShell has led to several exploit frameworks such as PowerSploit, PowerView,and PowerShell Empire. However, few of these frameworks investigate network traffic for exploitative potential. Analyzing a small amount of network traffic can lead to the discovery of possible network-based attack vectors such as Virtual Router Redundancy Protocol (VRRP), Dynamic Trunking Protocol (DTP), Link Local Multicast Name Resolution (LL-MNR) and PXE boot attacks, to name a few. How does one gather and analyze this traffic when Windows does not include an integrated packet analysis tool? Microsoft Windows PowerShell includes several network analysis and network traffic related capabilities. This paper will explore the use of these capabilities with the goal of building a PowerShell reconnaissance module which will capture, analyze, and identify commonly misconfigured protocols without the need to install a third-party tool within a Microsoft Windows environment.

Snort and SSL/TLS Inspection by Yousef Bakhdlaghi - April 20, 2017 in Intrusion Detection, Encryption & VPNs
An intrusion detection system (IDS) can analyze and alert on what it can see, but if the traffic is tunneled into an encrypted connection, the IDS cannot perform its analysis on that traffic. The difficulty of looking into the packet payload makes the encrypted traffic one of the challenging issues to IDS. In Snort, the encrypted traffic inspector is available optionally and can only inspect connections’ handshakes with no further inspection of the payload after the connection has established. However, encrypted traffic can be entirely decrypted using the private key (decryption key), but there are some issues associated with SSL/TLS key exchanges that could increase the difficulty of decrypting traffic provided the private key.
Auto-Nuke It from Orbit: A Framework for Critical Security Control Automation STI Graduate Student Research
by Jeremiah Hainly - March 15, 2017 in Automation, Incident Handling, Free and Open Source Software
Over 83% of security teams report that the use of automation in security needs to increase within the next three years (Algosec, 2016). With automation becoming a reality for a growing number of companies, there will also be an increased demand for open-sourced scripts to get started. This paper will provide a framework for prioritizing and developing security automation and will demonstrate this process by creating a script to automate a common information security response procedure - the reimaging of an infected endpoint. The primary function of the script will be to access the application program interface (API) of various enterprise software solutions to speed up the manual tasks involved in performing a reimage.

Tracking Online Counterfeiters by Emilio Casbas - March 16, 2017 in Intrusion Detection
The counterfeiting market makes-up a vast global business where the impact of fraudulent activity is hard to quantify. Counterfeiting is a global issue which has become more complex as black market activities moved to internet. The online counterfeiters create thousands of websites with different approaches as part of their strategy to lure unsuspected shoppers. This paper presents their most common tactics and its relation with the "Black market commoditization". It will show its resilience against takedown efforts and it will provide some guidance about how to detect them. With the knowledge acquired, a new kind of threat intelligence feed could be generated. This information might be integrated into existing security technologies such as either proxies, Intrusion Detection Systems (IDSs) or Security Information and Event Management systems (SIEMs). The ultimate goal is to shed light on this increasing fraud vector so new detection capabilities can be deployed into existing services thus protecting users from unsafe sites.
OS X as a Forensic Platform STI Graduate Student Research
by David M. Martin - February 22, 2017 in Mac/Apple Issues, Forensics
The Apple Macintosh and its OS X operating system have seen increasing adoption by technical professionals, including digital forensic analysts. Forensic software support for OS X remains less mature than that of Windows or Linux. While many Linux forensic tools will work on OS X, instructions for how to configure the tool in OS X are often missing or confusing. OS X also lacks an integrated package management system for command line tools. Python, which serves as the basis for many open-source forensic tools, can be difficult to maintain and easy to misconfigure on OS X. Due to these challenges, many OS X users choose to run their forensic tools from Windows or Linux virtual machines. While this can be an effective and expedient solution, those users miss out on the much of the power of the Macintosh platform. This research will examine the process of configuring a native OS X forensic environment that includes many open-source forensic tools, including Bulk Extractor, Plaso, Rekall, Sleuthkit, Volatility, and Yara. This process includes choosing the correct hardware and software, configuring it properly, and overcoming some of the unique challenges of the OS X environment. A series of performance tests will help determine the optimal hardware and software configuration and examine the performance impact of virtualization options.
Detection of Backdating the System Clock in Windows by Xiaoxi Fan - March 15, 2017 in Forensics
In the digital forensic industry, evidence concerning date and time is a fundamental part of many investigations. As one of the most commonly used anti-forensic approaches, system backdating has appeared in more and more investigations. Since the system clock can be set back manually, it is important for investigators to identify the reliability of date and time so as to make further decision. However, there is no simple way to tell whether the system clock has been backdated or tampered especially when it was subsequently reset to the correct time. There are a variety of artifacts to detect the behavior of backdating the system clock. If the investigator needs to prove the hypothesis that "the system clock has not been backdated," he or she must examine multiple artifacts for corroboration.

Results of this survey suggest that we may need to broaden the definition of an endpoint to include users, as the two most common forms of attack reported are directed at users. Lack of adequate patching programs also results in endpoint compromises, despite reported centralized endpoint management. Results also point to the need for improved detection, response, automation of remediation processes.
