Interaction Between Nokia Intrusion Prevention and Nokia Firewall
White Paper Firewalls provide protection between the external networks and internal networks by blocking potentially malicious traffic from entering the internal network infrastructure. However, inherently firewalls need to allow SMTP/email, FTP, SIP/VoIP... [09 Jul 2008]
VoIP Intrusion Detection Through Interacting Protocol State Machines
White Paper Moreover, given that voice communication is time sensitive and uses a suite of interacting protocols, VoIP exposes new forms of vulnerabilities to malicious attacks. Being a fast-growing Internet application, Voice over Internet Protocol (VoIP... [06 Jul 2008]
Agent-Based Network Intrusion Detection System
White Paper The proposed detection algorithm is based on extension of trust modeling techniques with representation of uncertain identities, context representation and implicit assumption that significant traffic anomalies are a result of potentially... [05 Jul 2008]
An Intelligent Firewall to Detect Novel Attacks
White Paper This paper supports on the concept of an intelligent firewall that contains a smart detection engine for potentially malicious data packets. The smart detection engine will aim at not only detecting anomalous network traffic as in classical IDSs... [30 Jun 2008]
The Critical Importance of Three-Dimensional Protection (3DP) in an Intrusion Prevention System
White Paper While IDSs enable record-keeping, an alarm function, and eventual analysis and remediation, they do not stop or mitigate damage from malicious attacks in real time. Many companies also employ network intrusion detection systems (IDS), which inspect... [31 May 2008]
Detecting Critical Nodes for MANET Intrusion Detection Systems
White Paper Detecting malicious nodes in an open ad hoc network in which participating nodes have no previous security associations presents a number of challenges not faced by traditional wired networks. Ad hoc routing protocols have been designed to... [31 May 2008]
Intrusion Defense Firewall
White Paper The network approach offers several advantages by blocking malicious code before it impacts the host, targeting potential vulnerabilities in addition to known exploits, and providing proactive vulnerability-facing network inspection. [31 May 2008]
OPTWALL: A Hierarchical Traffic-Aware Firewall
White Paper The main features of the proposed approach are the hierarchical design, splitting techniques, an online traffic adaptation mechanism, and a strong reactive scheme to counter malicious attacks (e.g. The overall efficiency, reliability, and... [31 May 2008]
TechNet Webcast: Deploying ISA Server 2004 to Protect Internal Network Segments From RPC-Based Attacks (Level 300)
White Paper It is all too common to encounter malicious code that end users have inadvertently installed on their systems. This webcast describes how deploying an application layer filtering solution such as Microsoft Internet Security and Acceleration (ISA... [01 May 2008]
Diverse Firewall Design
White Paper An error in a firewall policy either creates security holes that will allow malicious traffic to sneak into a private network or blocks legitimate traffic and disrupts normal business processes, which in turn could lead to irreparable, if not... [16 Apr 2008]
Formal Verification of Firewall Policies
White Paper A firewall policy error either creates security holes that will allow malicious traffic to sneak into a private network or blocks legitimate traffic and disrupts normal business processes, which in turn could lead to irreparable, if not tragic... [16 Apr 2008]
Change-Impact Analysis of Firewall Policies
White Paper A firewall policy error either creates security holes that will allow malicious traffic to sneak into a private network or blocks legitimate traffic and disrupts normal business processes, which in turn could lead to irreparable, if not tragic... [16 Apr 2008]
TechNet Webcast: Securing Your Messaging Traffic - Comprehensive Protection for Your Microsoft ISA Servers (Level 200)
White Paper Microsoft ISA Server works to keep inappropriate traffic and users out of the network and confidential data, but how are people making sure that the traffic that gets through is free from malicious code and inappropriate material? [12 Apr 2008]
Cisco Security Advisory: Cisco Secure Intrusion Detection System Signature Obfuscation Vulnerability
White Paper Intrusion Detection Systems inspect network traffic for suspect or malicious packet formats, data payloads and traffic patterns. This encoding technique known as %u can be used to circumvent intrusion detection systems, and has been made public by... [10 Apr 2008]
IPS Vs. IDS: Similar on the Surface, Polar Opposites Underneath
White Paper IPS and IDS both detect malicious or unwanted traffic. Although IPS and IDS both examine traffic looking for attacks, there are critical differences. But an IPS is an in-line device designed for automatic enforcement of network policy, whereas an... [28 Feb 2008]
