A Practical Example of Incident Response to a Network Based Attack STI Graduate Student Research
by Gordon Fraser - August 16, 2017A commonly accepted Incident Response (IR) process includes six phases: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. This paper examines this process in the context of a practical working example of a network based attack. It begins with the identification of a potential incident, followed by the detailed analysis of the network traffic to reconstruct the actions of the attacker, and leads up to determining indicators of compromise that can be used to identify other victims. This paper provides a practical example of responding to a network based incident.

The primary strengths of security operations centers (SOCs) are flexibility and adaptability, while their biggest weakness is lack of visibility. Survey results indicate a need for more automation across the prevention, detection and response functions. There are opportunities to improve security operations, starting with coordination with IT operations. SOCs can improve their understanding how to serve the organization more effectively and their use of metrics.

Auto-Nuke It from Orbit: A Framework for Critical Security Control Automation STI Graduate Student Research
by Jeremiah Hainly - March 15, 2017Over 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.

Node Router Sensors: What just happened? by Kim Cary - November 22, 2016
When an airliner crashes, one of the most important tasks is the recovery of the flight recorder or black box. This device gives precise & objective information about what happened and when before the crash. When an information security incident occurs on a network, it is equally important to have access to precise information about what happened to the victim machine and what it did after any compromise. A network of devices can be designed, economically constructed and managed to automatically capture and make available this type of data to information security incident handlers. In any environment, this complete record of network data comes with legal and ethical concerns regarding its use. Proper technical, legal and ethical operation must be baked into the design and operational procedures for devices that capture information on any network. These considerations are particularly necessary on a college campus, where such operations are subject to public discussion. This paper details the benefits, designs, operational procedures and controls and sample results of the use of "Node Router Sensors" in solving information security incidents on a busy college network.

BGP Hijinks and Hijacks - Incident Response When Your Backbone Is Your Enemy STI Graduate Student Research
by Tim Collyer - November 21, 2016The Border Gateway Protocol (BGP) is used to route packets across the Internet, usually at the level of the Internet backbone where Internet Service Providers (ISPs) pass traffic amongst themselves. Unfortunately, BGP was not designed with security in mind, like many of the protocols used in modern networks such as the Internet. Lack of security within BGP means that traffic is susceptible to misdirection and manipulation through either misconfiguration or malicious intent. Among the traffic manipulation possible within BGP routing is Autonomous System (AS) path injection, in which a new router can insert itself into the routing path of traffic. This can create a man-in-the-middle condition if the path injection is malicious in nature. Differentiation between a malicious incident and mere misconfiguration can be extremely challenging. Even more difficult for an affected company is to conduct incident response during a BGP-related incident. This paper explores the incident response options currently available to security teams to prevent, detect, and where possible, respond should a BGP incident arise.

Keys to Effective Anomaly Detection by Matt Bromiley - October 25, 2016
- Sponsored By: Blue Coat Systems, Inc.
Simply put, an anomaly is something that seems abnormal or doesn’t t within an environment. A car with ve driving wheels would be an anomaly. In the context of an enterprise network, an anomaly is very much the same—something that does not t or is out of place. While anomalies in an enterprise network may be indicative of a con guration fault, they are often evidence of something much more worrisome: a malicious presence on the network.

Detecting Incidents Using McAfee Products by Lucian Andrei - October 10, 2016
Modern attacks against computer systems ask for a combination of multiple solutions in order to be prevented and detected. This paper will do the analysis of the capacities of commercial tools, with minimal configuration, to detect threats. Traditionally, companies use antivirus software to protect against malware, and a firewall combined with an IDS to protect against network attacks. This paper will analyze the efficacy of the following three combinations: antivirus, antivirus plus host IDS, and antivirus combined with a host IDS plus application whitelisting in order to withstand application attacks. Before doing the tests we predicted that the antivirus will block 20% of the attacks, the HIDS will detect an additional 15%, and McAfee Application Control will protect at least against 50% more of the attacks executed by an average attacker using known exploits, without much obfuscation of the payload. The success of defensive commercial tools against attacks will justify the investment a company will be required to make.

Demystifying Malware Traffic by Sourabh Saxena - August 29, 2016
In today's world, adversaries use established techniques, innovative and intricate methods for cyber-crimes and to infiltrate firms or an individual's system. Usage of Malware is one of those approaches. Malware not only creates an inlet for attacks, but it also turns systems into "zombies" and "bots" forcing them to obey commands and perform activities as per the whims and fancies of the adversary. Thus, attacks like data theft, mail relay, access to confidential/restricted area, Distributed Denial-of-Service (DDoS) can easily be launched against not just the infected system but against other systems and environments as well by utilizing these zombies, bots, and botnets. Attackers not only obfuscate the code but can encrypt payloads as well as malware's traffic simultaneously, using approaches like mutation and polymorphism making their detection difficult not just for antiviruses, but even for firewalls, IDS and IPS, Incident Handlers, and Forensic teams. Organizations, having learned from past mistakes, have also shifted their approach from simple defense mechanisms such as antiviruses, IDS and IPS to aggressive strategies like DNS Sinkhole and Live Traffic Analysis. These strategies not only help in the identification and removal of malware but also in understanding the actual impact, blocking of malicious activities and identification of adversaries.

Lessons Learned from Treatment of Trauma in Individuals and Organizations Under Repeated Cyber Attacks by Vanessa Pegueros - June 13, 2016
There has been significant research relative to the impacts of trauma on human beings and the associated treatment of that trauma. With the increasing frequency of cyber-attacks and associated breaches, people within organizations are experiencing similar traumatic effects felt by victims of a more physical attack or incident. There are significant parallels between the impacts of cyber-attacks on organizations and the impacts on individuals experiencing some form of trauma. There are key lessons to be learned from the treatment of trauma victims and the techniques to help organizations become more prepared and resilient relative to cyber- attacks. With the continued escalation of cyber-attacks, organizations should be working to implement solutions beyond just security technology and look to the process and people elements of the solution.

Deployment of a Flexible Malware Sandbox Environment Using Open Source Software by Jose Ortiz - August 24, 2015
The identification and analysis of malware is one of the many tasks performed by incident handlers. Only a small number of commercial entities provide the technology capable of automating this. Most times these offerings are beyond the reach of small organizations due to the high costs associated with licensing and maintenance. One open source alternative is Cuckoo Sandbox. It is a free software project licensed under GNU GPLv3. It allows the user to analyze and collect data against suspected pieces of malware. The framework installation requires careful configuration by an experienced Linux administrator. The accepted method of deployment is to follow the prescribed steps and test the application “until it works.” Attempting to scale the sandbox environment beyond a few virtual machines becomes a complicated process due to the maintenance required for multiple Windows configurations. By using techniques borrowed from the DevOps methods, a small team of incident handlers can create a sandbox environment that is not only repeatable and consistent, but also scalable. The user can create multiple template “profiles,” which allow for flexible testing.

Coding For Incident Response: Solving the Language Dilemma STI Graduate Student Research
by Shelly Giesbrecht - July 28, 2015Incident responders frequently are faced with the reality of "doing more with less" due to budget or manpower deficits. The ability to write scripts from scratch or modify the code of others to solve a problem or find data in a data "haystack" are necessary skills in a responder's personal toolkit. The question for IR practitioners is what language should they learn that will be the most useful in their work? In this paper, we will examine several coding languages used in writing tools and scripts used for incident response including Perl, Python, C#, PowerShell and Go. In addition, we will discuss why one language may be more helpful than another depending on the use-case, and look at examples of code for each language.

Incident Tracking In The Enterprise by Justin Hall - July 20, 2015
Some organizations employ Computer Security Incident Response Teams (CSIRTs) to investigate and respond to security incidents. They often find these investigations to be poorly executed, time consuming, and ultimately ineffective at discovering the root cause of a breach. Unfortunately, this is not usually due to the skill of the investigators, but rather due to the tools and processes they use to manage the investigations. This paper describes the use of purpose built case management software, integrated into the incident response process, to track these investigations. CSIRTs that take an organized, formal tracking approach will collaborate better and find their investigations to be more complete and useful to risk managers.

Psychology and the hacker - Psychological Incident Handling by Sean Atkinson - July 9, 2015
The understanding of the processes, techniques and skills of hackers or cyber-criminals can be ascertained through the practical application of forensic psychology techniques and behavioral analysis. The actions and methods used within an attack, through the monitoring of logs and forensic discovery, will contribute to a profile of the person/persons behind the intrusion. This information will be a new vector in determining infiltration techniques, if the actions leave a persistent threat (backdoor) or if it is a one-time “smash and grab”. If applied correctly, the detective controls can shorten avenues of determining risk and threats, as well as the magnitude of investigation required based upon the behavioral profile. Incident handling is based on the detection, response and resolution of security incidents. Given a new understanding of the person/persons behind such an incident, the process will be a preliminary part of the incident handling process. Using the methods of behavioral analysis, it creates a new dimension of understanding to the malicious activity and network analysis of what occurred in the environment.

Integrating Forensic Investigation Methodology into eDiscovery by Colin Chisholm - September 7, 2010
The intent of this paper is twofold; to provide a primer on the eDiscovery process for forensic analysts and to provide guidance on the application of forensic investigative methodology to said process. Even though security practitioners such as forensic analysts operate in the legal vertical, they necessarily view and approach eDiscovery from a different perspective than legal professionals. This paper proposes that both parties can benefit when they integrate their processes; forensic tools and techniques have been used in the collection, analysis and presentation of evidence in the legal system for years. The history, and precedent, of applying forensic science to the legal process can be leveraged into the eDiscovery process. This paper will also detail how the scope and work for a forensic investigator during the eDiscovery process differs from a typical forensic investigation.

Orion Incident Response Live CD STI Graduate Student Research
by John Jarocki - May 7, 2010There are many frameworks for incident handling, including the Security Incident Handling Guide from the National Institute of Standards and Technology (NIST) (Scarefone, Grance, & Masone, 2008), (Mandia, Prosise, & Pepe, 2003), and the SANS six-step handling process (Skoudis, 2009). Carnegie-Mellon’s Software Engineering Institute even provided a study of these and more along with a framework for creating an incident management process tuned for a specific organization (Albert, Dorofee, Killcrece, & Zajicek, 2004). Tools for incident handling and response also exist, but responder tool kits are often built by collecting important tools one at a time until the expert incident handler has a custom set. This makes it difficult to bring in less-experienced incident response team members, and it creates challenges for collaboration during the incident as well as consistent collection and storage of evidence. Some Incident Response environments do exist, but they primarily focus on the analysis process, and do not provide a communication and collaboration framework. Nor do they usually provide a workflow based environment.
