Development of A Packet Simulator for Performance Test of Information Security System
"... Abstract Development of information security system is brought by problem by the development of network environment, and the need of equipment for performance test, but performance test equipments are expensive and difficult to use. Therefore, we need an environment which can develop a performance t ..."

test for an information security system. In this paper, the design and implementation of an APS(Attack Packet Simulator) extracts the attack information from Snort rule and creates an attack information in the Database using the extracted information. Stored information in the database creates
Timing Analysis of Keystrokes and Timing Attacks on SSH
"... SSH is designed to provide a secure channel between two hosts. Despite the encryption and authentication mechanisms it uses, SSH has two weakness: First, the transmitted packets are padded only to an eight-byte boundary (if a block cipher is in use), which reveals the approximate size of the origina ..."

and our key sequence prediction algorithm, we can predict key sequences from the interkeystroke timings. We further develop an attacker system, Herbivore, which tries to learn users ’ passwords by monitoringSSH sessions. By collecting timing information on the network, Herbivore can speed up exhaustive
CYBER ATTACK MODELING AND SIMULATION FOR NETWORK SECURITY ANALYSIS
"... Cyber security methods are continually being developed. To test these methods many organizations utilize both virtual and physical networks which can be costly and time consuming. As an alternative, in this paper, we present a simulation modeling approach to represent computer networks and intrusion ..."

and intrusion detection systems (IDS) to efficiently simulate cyber attack scenarios. The outcome of the simulation model is a set of IDS alerts that can be used to test and evaluate cyber security systems. In particular, the simulation methodology is designed to test information fusion systems for cyber
PacketScore: a statistics-based packet filtering scheme against distributed denial-of-service attacks
- IEEE Transactions on Dependable and Secure Computing
, 2006
"... Abstract—Distributed Denial-of-Service (DDoS) attacks are a critical threat to the Internet. This paper introduces a DDoS defense scheme that supports automated online attack characterizations and accurate attack packet discarding based on statistical processing. The key idea is to prioritize a pack ..."

through scorebook generation and pipeline processing. A simulation study indicates that PacketScore is very effective in blocking several different attack types under many different conditions. Index Terms—Network level security and protection, performance evaluation, traffic analysis, network monitoring
Secure Communication against Vampire Attacks in WSN (Survey)
"... Abstract — WSN is a group of wireless nodes in which each node communication with each other. Each sensor node comprises sense, giving out transmission, location finding structure, and control units. Sensor nodes are typically spread in sensor field, which is an area where the sensor nodes are deplo ..."

Detection of Fabricated CTS Packet Attacks in Wireless LANs
"... Abstract. IEEE 802.11 standard employs the RTS/CTS handshake procedure to avoid transmission collision and to improve network throughput. However, such an exchange may become a system vulnerability when malicious nodes send fabricated control messages such as CTS to make false claims of channel rese ..."

With the help of two-hop neighborhood information, our technique enables jamming detection and allows the targeted node to send a message, which instructs neighboring nodes to ignore the fabricated control message. We perform ns-2 simulations to evaluate the benefit of our scheme.
FLOODING ATTACK AWARE SECURE AODV
"... Providing security in a Mobile Ad hoc Network (MANET) is a challenging task due to its inherent nature. Flooding is a type of Denial of Service (DoS) attack in MANET. Intentional flooding may lead to disturbances in the networking operation. This kind of attack consumes battery power, storage space ..."

Evasion attacks against machine learning at test time
- in European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases
, 2013
"... Abstract. In security-sensitive applications, the success of machine learn-ing depends on a thorough vetting of their resistance to adversarial data. In one pertinent, well-motivated attack scenario, an adversary may at-tempt to evade a deployed system at test time by carefully manipulating attack s ..."

However it is often overlooked when these systems are tested, partly because human tests are costly and very hard to repeat. We have developed a community of agents that test secure systems by running standard windows ..."
