Building and Maintaining a Denial of Service Defense for Businesses STI Graduate Student Research
by Matt Freeman - January 25, 2017
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.
Detecting and Preventing Attacks Earlier in the Kill Chain STI Graduate Student Research
by Chris Velazquez - August 31, 2015
Most organizations place a strong focus on intrusion prevention technologies and not enough effort into detective technologies. Prevention of malicious attacks is ideal, but detection is mandatory in combatting cyber threats. Security vendors will only provide blocking signatures when there is a near zero false-positive rate. Because of this, there are signatures that are not implemented resulting in false-negatives from one’s security devices. This paper provides a look at tools that can be used to improve the detection of attackers at every phase of their attack. The intelligence learned from these attacks allows one to defend against these known attack vectors. This paper will look at a variety of open-source network IDS capabilities and other analysis tools to look at preventing and detecting attacks earlier in the cyber kill chain.
Getting Started with the Internet Storm Center Webhoneypot STI Graduate Student Research
by Mason Pokladnik - December 12, 2013
The DShield/Internet Storm Center (ISC) Webhoneypot is a new project from DShield--a distributed intrusion detection system--that extends its logging capabilities from layer 3 and 4 network traffic further up the OSI layers to help study application layer attacks.
Introduction to the OWASP Mutillidae II Web Pen-Test Training Environment by Jeremy Druin - October 22, 2013

Secure Perimeter Network Design for GIAC Enterprises by Ted Franger - May 17, 2005
This paper puts forth a secure perimeter network design for the fictional company GIAC Enterprises, which is in the business of brokering fortune cookie sayings. The paper consists of three assignments and is completed in fulfillment of the requirements of a practical exam for the GIAC Certified Firewall Analysis Certification.
Possible Points of Failure in the Information Security Environment by Marion Qualls - July 25, 2004
The task of designing a secure infrastructure for IIS 5.0 web servers within a DMZ is difficult enough. Securing an existing DMZ becomes exponentially more difficult due to the added requirement of retrofitting those currently working servers with more appropriate security settings, policies and operational procedures while not adversely affecting website or application availability and keep costs to a minimum throughout the process.

Most of the computer security white papers in the Reading Room have been written by students seeking GIAC certification to fulfill part of their certification requirements and are provided by SANS as a resource to benefit the security community at large. SANS attempts to ensure the accuracy of information, but papers are published "as is". Errors or inconsistencies may exist or may be introduced over time as material becomes dated.
