Peer-to-Peer Connectivity Using Firewall and Network Address Translator Traversal
White Paper Network Address Translators (NATs) and Firewalls, also collectively called middleboxes, create problems for establishing connections in peer-to-peer (P2P) networks: They limit the outbound connections to the Internet, do not allow incoming... [10 Jul 2008]
Overcoming NAT and Firewall Connectivity Restrictions in Overlay Multicast
White Paper However, in reality, this assumption is not valid with widespread use of Network Address Translators (NAT) and firewalls. The impact of NAT and firewall connectivity restrictions on overlay multicast, especially in the application-endpoint setting... [10 Jul 2008]
Adaptive Detection of Worms/Viruses in Firewalls
White Paper All packets pass through firewalls and only firewalls are able to prevent packets from entering the network. It present the firewall model and address how to detect worms/viruses based on protocol sanity, probabilistic estimation of maliciousness... [10 Jul 2008]
The Use and Usability of Direction-Based Filtering in Firewalls
White Paper However, most firewalls are also capable of filtering based on a packet's direction: which network interface card the packet is crossing, and whether the packet is crossing the interface from the network into the firewall (''Inbound'') or vice... [10 Jul 2008]
Configuring Management Central Connections for Firewall Environments
White Paper To assist in configuring Management Central within a firewall environment, this report discusses the nature and orientation of Management Central connections and the restrictions of specific types of firewalls that limit or disable some Management... [10 Jul 2008]
Deep Inspection: Next Generation Firewall Technology
White Paper A new generation of deep inspection firewalls is emerging to address the growing threat to web applications. Stateful inspection firewalls are the most-widely used defense against hackers. Stateful inspection firewalls were never designed to... [10 Jul 2008]
NAT and Firewall Traversal Technical Report
White Paper While NATs and Firewalls provide numerous benefits to the customer, they also create numerous challenges for service providers seeking to offer seamless communication services to applications located behind the customer's NAT/Firewall device. [09 Jul 2008]
An NSIS-Based Approach for Firewall Traversal in Mobile IPv6 Networks
White Paper This paper describes the problems and impacts of having firewalls in Mobile IPv6 environments and presents a firewall traversal solution based on the IETF's Next Steps in Signaling framework to address these issues. [09 Jul 2008]
Implementation and Performance Study of a New NAT/Firewall Signaling Protocol
White Paper This new protocol allows end hosts to signal along a path to configure NATs and firewalls according to the data flow needs. The NAT/Firewall NSIS Signaling Layer Protocol (NAT/Firewall NSLP) is a path-coupled signaling protocol for explicit Network... [08 Jul 2008]
The Purpose of a SIP-Aware Firewall/ALG
White Paper In addition, this paper will highlight problems that NAT causes for SIP, and how SIP firewalls/ALGs resolve the problem. Provided in this document is a brief description of the SIP and Network Address Translation (NAT) technologies. [08 Jul 2008]
An Intrusion Detection Game With Limited Observations
White Paper By extending the information security paradigm beyond traditional protective (e.g.firewalls) and reactive measures (e.g.virus and malware detection), they increase the controlling ability of the system administrator, and help him or her manage... [07 Jul 2008]
Evaluating Application-Aware Firewall Performance
White Paper The rise of application-layer DoS attacks, the popularity of Network Address Translation (NAT), and the need for advanced network security capabilities have spawned the development of application-aware firewalls. [30 Jun 2008]
Traversing Firewalls and NATs With Voice and Video Over IP
White Paper Firewalls block IP voice and video traffic by placing a barrier to any unsolicited, incoming communications. Unfortunately, the ability to capitalize on IP communications systems has been severely delayed because nearly all corporate networks have... [03 Jun 2008]
NAT/Firewall Traversal: Issues and Solutions
White Paper Network Address Translators (NATs) and Firewalls are increasingly used in all type of networks because of various reasons. However, NATs and firewalls are limiting some kind of communications and they are known to cause problems for applications... [31 May 2008]
Using JXTA for Firewall Traversal in Distributed CORBA Applications
White Paper Binding CORBA and JXTA technologies together allows components of distributed CORBA applications to be deployed in complex network environments, which may contain firewalls or IP address translators. JXTA is a peer-to-peer protocol stack, also... [31 May 2008]
