whitepaper Managed Service Is the Answer for Email Security in K-12 Education2007-09-12 Red Condor
  As one of 58 county offices of education in California, Sonoma County Office of Education (SCOE) is an educational service agency and strategic partner to the 43 school districts in Sonoma County and their 177 individual schools. SCOE wanted to provide a cost-effective spam-filtering solution to SCOE's districts with a high degree of protection and low false positives, while preventing spam campaigns from overloading their one email server. SCOE deployed Red Condor Message Assurance Gateway hosted solution which blocks malicious email before it reaches the customer network. It provides simultaneous inbound and outbound security. It removes the burden of email-borne DoS (Denial of Service) and DHA (Directory Harvest Attacks) on the email server and network connection.

whitepaper Potential Cognitive Radio Denial of Service Attacks and Remedies2007-09-04 University of Colorado
  Cognitive radios sense spectrum activity and apply spectrum policies in order to make decisions on when and in what bands they may communicate. These activities go beyond what is done when traditional radios communicate. This paper examines the denial of service vulnerabilities that are opened by these additional activities and explores potential remedies that can be applied. The goal is to assist cognitive radio designers to incorporate effective security measures now in the early stages of cognitive radio development.

whitepaper Minimizing Collateral Damage by Proactive Surge Protection2007-08-27 Association for Computing Machinery
  Existing mechanisms for defending against Distributed Denial-of-Service (DDoS) attacks are generally reactive in nature. However, the onset of large-scale bandwidth-based attacks can occur suddenly, potentially knocking out substantial parts of a network before reactive defenses can respond. Even for traffic flows that are not under direct attack, significant collateral damage will result if these flows pass through links that are common to attack routes. This paper presents a Proactive-Surge-Protection (PSP) mechanism that aims to provide a broad first line of defense against DDoS attacks. Their solution aims to minimize collateral damage by providing bandwidth isolation between traffic flows. This isolation is achieved through a combination of traffic forecasting, proportional allocation of network capacity, metering and tagging of packets at the network perimeter, and preferential dropping of packets inside the network.

whitepaper A Taxonomy for Denial-of-Service Attacks in Wireless Sensor Networks0000-00-00 University of Virginia
  Wireless Sensor Networks (WSNs) are transitioning to real-world applications, where they face attacks already experienced by the Internet and wireless ad hoc networks. One such attack is that of Denial-Of-Service (DOS), which is believed will only become more prevalent as sensor networks become more pervasive and accessible. With the inherent resource limitations of WSN devices, they are particularly susceptible to the consumption and destruction of these scarce resources. This paper presents DOS attack taxonomy to identify the attacker, his capabilities, and the target of the attack, vulnerabilities used, and the end result. This paper surveys vulnerabilities in WSNs and give possible defenses.

whitepaper The Real Cost of Spam for City Workers Adds Up Fast2007-08-15 Red Condor
  The City of Petaluma & the City of Santa Rosa needed to deploy solutions that are economic and help increase employee productivity, maintaining efficiency, seamless protection against spam. The City deployed Red Condor Message Assurance Gateway which blocks malicious email before it reaches the customer network. It provides simultaneous inbound and outbound security. It removes the burden of email-borne DoS (Denial of Service) and DHA (Directory Harvest Attacks) on the email server and network connection. And it's a fully managed, network-resilient system with integrated emergency spooling of inbound email.

whitepaper Better Security through Access-List Management2007-08-09 Global Knowledge
  Security concerns are becoming more common in every environment, regardless how big or small the network. You can get limited security with the access-list on your routers. This paper gives you the basics of access-list with implementations examples as covered in the CCNA certifications.

whitepaper Cisco Security Advisory: Denial of Service Vulnerability in Cisco Wide Area Application Services (WAAS) Software2007-07-18 Cisco Systems
  The Cisco Wide Area Application Services (WAAS) software contains a Denial of Service (DoS) vulnerability that may cause some devices that run WAAS software (WAE appliance and NM-WAE 502 module) to stop processing all types of traffic, including data traffic and management traffic. This condition may occur if a device running WAAS software is configured for Edge Services, which utilizes Common Internet File System (CIFS) optimization and receives a flood of TCP SYN packets on port 139 or 445. Cisco has made free software available to address this vulnerability for affected customers. Workarounds are available to mitigate the effects of this vulnerability.

whitepaper A Denial-of-Service Resistant DHT2007-07-17 Johns Hopkins University
  This paper considers the problem of designing scalable and robust information systems based on multiple servers that can survive even massive Denial-of-Service (DoS) attacks. More precisely, the paper focusing on designing a scalable Distributed Hash Table (DHT) that is robust against so-called past insider attacks. In a past insider attack, an adversary knows everything about the system up to some time point t0 not known to the system. After t0, the adversary can attack the system with a massive DoS attack in which it can block a constant fraction of the servers of its choice.

whitepaper Impact of Denial of Service Attacks on Ad Hoc Networks2007-07-16 Institute of Electrical and Electronics Engineers
  Significant progress has been made towards making ad hoc networks secure and DoS resilient. However, little attention has been focused on quantifying DoS resilience: Do ad hoc networks have sufficiently redundant paths and counter-DoS mechanisms to make DoS attacks largely ineffective? Or are there attack and system factors that can lead to devastating effects? This paper designs and study DoS attacks in order to assess the damage that difficult-to-detect attackers can cause.

whitepaper Design and Development of Proactive Models for Mitigating Denial-of-Service and Distributed Denial-of-Service Attacks2007-07-01 National Institute of Technology Karnataka
  Denial-of-Service (DoS) attacks, orchestrated by a single host or multiple hosts in a coordinated manner, have become an increasingly frequent disturbance in today's Internet. Generally, attackers launch Distributed Denial-of-Service (DDoS) attacks by directing a massive number of attack sources to send useless traffic to the victim. The victim's services are disrupted when its host or network resources are occupied by the attack traffic. The threat of DDoS attacks has become even more severe as attackers can compromise a huge number of computers using vulnerabilities in popular operating systems. This paper deals with proactive models for mitigating DoS and DDoS attacks.
