whitepaper Quality of Service (QoS) is the ability to treat packets differently as they transit a network device, based on the packet contents. Without QoS, all packets on the network vie for the same pool of resources, and when congestion occurs.

whitepaper This paper shows how an attacker can reconstruct a firewall's policy by probing the firewall by sending tailored packets into a network and forming an idea of what the policy looks like. The first approach is based on region growing from single...

whitepaper It shows how an attacker can reconstruct a firewall's policy by probing the firewall with tailored packets into a network and forming an idea of what the policy looks like. Three techniques are proposed for reconstructing the policy as well as to...

whitepaper These critical devices filter traffic by comparing arriving packets to a list of rules, or security policy, in a sequential manner. Network firewalls remain the forefront defense for most computer systems.

whitepaper A firewall is a security guard placed at the point of entry between a private network and the outside Internet such that all incoming and outgoing packets have to pass through it. The function of a firewall is to examine every incoming or outgoing...

whitepaper FIREMAN performs symbolic model checking of the firewall configurations for all possible IP packets and along all possible data paths. Security concerns are becoming increasingly critical in networked systems.
[03 May 2008]
whitepaper An example of a firewall query is "Which computers in the private network can receive packets from a known malicious host in the outside Internet? Firewalls are crucial elements in network security, and have been widely deployed in most businesses...

News Male techies are willing to reveal the size of their pay packets if it helps women get a fairer pay deal. More than half (62 per cent) say they would come clean about what is in their wallets to help women get equal pay, according to recruitment...

whitepaper This calls for the necessity of analyzing the traffic (packets) on the network. Stateful firewall analyzes packets up to their layer 4 headers while NIDS analyzes the whole packet. Computer network is already an indispensable part of the modern life.
[24 Apr 2008]
whitepaper This instrumentation was used to test the host's firewall under two scenarios: In the first scenario, the path and the latency of one single packet are captured; in the second scenario, the latency of multiple packets sent to the host at various...

News Also, by sending sufficient crafted packets to the [Phorm] web server, attackers would get more bang for their buck, and the net effect would be [that] the server would not resolve anyone to the ISP. Security from A to Z

whitepaper In multihop wireless systems, such as ad-hoc and sensor networks, the need for cooperation among nodes to relay each other's packets exposes them to a wide range of security attacks. A particularly devastating attack is known as the wormhole attack...

whitepaper Network Intrusion Detection Systems (NIDS) inspect the content of incoming packets on a network for known attacks and alert the operator when they are found. Network intrusion detection has become increasingly popular in recent years due to the...

whitepaper However, wireless networks suffer from a number of problems that do not affect wired networks; in particular that the medium they use to transmit packets is a scarce resource subject to physical limits.

whitepaper The Snort IDS is well known for its efficiency in examining incoming packets and SPACEDIVE leverages the Snort functionality. Voices over IP (VoIP) systems are gaining in popularity as the technology for transmitting voice traffic over IP networks.

whitepaper Internet Protocol-based services have the potential to become a crucial component of many telecom companies' revenue. Executives must therefore understand how this technology affects one of their company's most important functions: billing.
[10 Apr 2008]
whitepaper The classification and conditioning of packets occurs on DS boundary nodes (or interior nodes - with limited conditioning) within the organization's core network and other DS Domains. The packets are marked and conditioned by the DS nodes to...
