With more traffic than ever passing through our environments, and adversaries who know how to blend in, network security analysts need all the help they can get. At the same time, data is leaking out of our environments right under our noses. This paper investigates how LogRhythm’s Network Monitor Freemium (NetMon Freemium) Version 3.2.3 provides intelligent monitoring, and helps organizations to identify sensitive data leaving the network and to respond when loss occurs.
The DevSecOps Approach to Securing Your Code and Your Cloud Analyst Paper
by Dave Shackleford - February 7, 2017 in Security Trends, Threats/Vulnerabilities
- Sponsored By: CloudPassage
DevSecOps, at heart, is about collaboration. More specifically, it is continual collaboration between information security, application development and IT operations teams. Having all three teams immersed in all development and deployment activities makes it easier for information security teams to integrate controls into the deployment pipeline without causing delays or creating issues by implementing security controls after systems are already running. Despite the potential benefits, getting started with DevSecOps will likely require some cultural changes and considerable planning, especially when automating the configuration and security of assets in the cloud. To help the shift toward a more collaborative culture, security teams need to integrate with the developers who are promoting code to cloud-based applications to show they can bring quality conditions to bear on any production code push without slowing the process. Security teams should also work with QA and development to define the key qualifiers and parameters that need to be met before any code can be promoted. This paper also has an additional resource titled, "DevSecOps Transformation: The New DNA of Agile Business". The resource can be accessed by clicking this link.
Countering Impersonation, Spearphishing and Other Email-Borne Threats: A Review of Mimecast Targeted Threat Protection Analyst Paper
by Jerry Shenk - January 24, 2017 in Data Loss Prevention, Social Engineering
The FBI estimates that between October 2013 and August 2015, more than 7,000 U.S.-based organizations lost a total of $748 million to business email scams. Such scams rely on the same tricks as confidence artists in the real world: the appearance of legitimacy and the tendency of victims to go along with requests that appear to be on the up-and-up, without checking to be sure. In this whitepaper, SANS senior analyst Jerry Shenk evaluates Targeted Threat Protect, an email-security service from Mimecast that is focused on stopping sophisticated phishing attacks. Among its most difficult targets: “whaling” attacks that spoof high-level executives asking for sensitive data, access or the transfer of money to accounts owned by scammers.
Attack and Defend: Linux Privilege Escalation Techniques of 2016 STI Graduate Student Research
by Michael Long II - January 30, 2017 in Linux Issues, Privilege Management, Penetration Testing
Recent kernel exploits such as Dirty COW show that despite continuous improvements in Linux security, privilege escalation vectors are still in widespread use and remain a problem for the Linux community. Linux system administrators are generally cognizant of the importance of hardening their Linux systems against privilege escalation attacks; however, they often lack the knowledge, skill, and resources to effectively safeguard their systems against such threats. This paper will examine Linux privilege escalation techniques used throughout 2016 in detail, highlighting how these techniques work and how adversaries are using them. Additionally, this paper will offer remediation procedures in order to inform system administrators on methods to mitigate the impact of Linux privilege escalation attacks.
Tracking Malware With Public Proxy Lists by James Powers - January 27, 2011 in Malicious Code, Tools
The Web was born on Christmas Day, 1990 when the CERN Web server (CERN httpd 1.0) went online. By version 2.0, released in 1993, CERN httpd, was also capable of performing as an application gateway. By 1994, content caching was added. With the publication of RFC 1945 two years later, proxy capabilities were forever embedded into the HTTP specification (Berners-Lee, Fielding, & Frystyk, 1996).
Back to Basics: Focus on the First Six CIS Critical Security Controls Analyst Paper
by John Pescatore - January 24, 2017 in Best Practices, Data Protection
- Sponsored By: Tripwire, Inc.
Rather than a lack of choices in security solutions, a major problem in cyber security is an inability to implement mature processes - many organizations lack a defined and repeatable process for selecting, implementing and monitoring the security controls that are most effective against real-world threats. This paper explores how the Center for Internet Security (CIS) Critical Security Controls has proven to be an effective framework for addressing that problem.

Forensication Education: Towards a Digital Forensics Instructional Framework STI Graduate Student Research
by J. Richard “Rick” Kiper - February 3, 2017 in Best Practices, Forensics, Training
The field of digital forensics is a diverse and fast-paced branch of cyber investigations. Unfortunately, common efforts to train individuals in this area have been inconsistent and ineffective, as curriculum managers attempt to plug in off-the-shelf courses without an overall educational strategy. The aim of this study is to identify the most effective instructional design features for a future entry-level digital forensics course. To achieve this goal, an expert panel of digital forensics professionals was assembled to identify and prioritize the features, which included general learning outcomes, specific learning goals, instructional delivery formats, instructor characteristics, and assessment strategies. Data was collected from participants using validated group consensus methods such as Delphi and cumulative voting. The product of this effort was the Digital Forensics Framework for Instruction Design (DFFID), a comprehensive digital forensics instructional framework meant to guide the development of future digital forensics curricula.

Building and Maintaining a Denial of Service Defense for Businesses STI Graduate Student Research
by Matt Freeman - January 25, 2017 in Critical Controls, Getting Started/InfoSec, Security Trends
Distributed Denial of Service (DDoS) attacks have been around for decades but still cause problems for most businesses. While easy to launch, DDoS attacks can be difficult to sustain and even more difficult to monetize for attackers. From the business perspective, a DDoS attack might result in lost revenue but is unlikely to have the same long term impact that a data breach may have. Recent changes in the IT landscape have made DDoS a more attractive attack vector for hackers. The industry trend to connect more and more devices to the Internet (often with minimal to no security), dubbed the "Internet of Things" has created a new marketplace for bad actors to sell their resource exhaustion services. Businesses need to consider all options when planning and implementing a defensive posture against denial of service attacks. As security vendors continue to offer new (and expensive) options to defend against these attacks, how does an InfoSec manager know which is best for their business. Using an "Offense informs the Defense" approach, this paper will analyze the methods used during DDoS attacks in order to determine the most appropriate defensive postures.

Additionally, this document includes a workflow for Security Operations Centers (SOC) to efficiently process events of interest thereby increasing the likelihood of detecting a breach. Methods include Intrusion Detection System (IDS) setup with tips on efficient data collection, sensor placement, identification of critical infrastructure along with network and metric visualization. These recommendations are useful for enterprises, small homes, or offices who wish to implement threat intelligence and network analysis.
Writing a Penetration Testing Report by Mansour Alharbi - April 29, 2010 in Best Practices, Penetration Testing
`A lot of currently available penetration testing resources lack report writing methodology and approach which leads to a very big gap in the penetration testing cycle. Report in its definition is a statement of the results of an investigation or of any matter on which definite information is required (Oxford English Dictionary). A penetration test is useless without something tangible to give to a client or executive officer. A report should detail the outcome of the test and, if you are making recommendations, document the recommendations to secure any high-risk systems (Whitaker & Newman, 2005). Report Writing is a crucial part for any service providers especially in IT service/ advisory providers. In pen-testing the final result is a report that shows the services provided, the methodology adopted, as well as testing results and recommendations. As one of the project managers at major electronics firm Said "We don't actually manufacture anything. Most of the time, the tangible products of this department [engineering] are reports." There is an old saying that in the consulting business: “If you do not document it, it did not happen.” (Smith, LeBlanc & Lam, 2004)
Finding Bad with Splunk STI Graduate Student Research
by David Brown - December 16, 2016 in Critical Controls
There is such a deluge of information that it can be hard for information security teams to know where to focus their time and energy. This paper will recommend common Linux and Windows tools to scan networks and systems, store results to local filesystems, analyze results, and pass any new data to Splunk. Splunk will then help security teams narrow in on what has changed within the networks and systems by alerting the security teams to any differences between old baselines and new scans. In addition, security teams may not even be paying attention to controls, like whitelisting blocks, that successfully prevent malicious activities. Monitoring failed application execution attempts can give security teams and administrators early warnings that someone may be trying to subvert a system. This paper will guide the security professional on setting up alerts to detect security events of interest like failed application executions due to whitelisting. To solve these problems, the paper will discuss the first five Critical Security Controls and explain what malicious behaviors can be uncovered as a result of alerting. As the paper progresses through the controls, the security professional is shown how to set up baseline analysis, how to configure the systems to pass the proper data to Splunk, and how to configure Splunk to alert on events of interest. The paper does not revolve around how to implement technical controls like whitelisting, but rather how to effectively monitor the controls once they have been implemented.
