  • IPS-1 is an intrusion prevention system (IPS) that delivers protection from a wide-range of network threats using an IPS-1 Sensor that can be placed either on the perimeter of your network or at any location in your internal network. Some of the benefits of IPS-1 include: Unified security management Mission-critical protection against known and unknown attacks Granular forensic analysis Flexible deployment Confidence Indexing

  • Insider attacks pose an often neglected threat scenario when devising security mechanisms for emerging wireless technologies. For example, traffic safety applications in vehicular networks aim to prevent fatal collisions and preemptively warn drivers of hazards along their path, thus preserving numerous lives. Unmitigated attacks upon these networks stand to severely jeopardize their adoption and limit the scope of their deployment.

  • The development and writing of this report presented considerable challenges in terms of both the study schedule and the need to avoid conveying sensitive U.S. vulnerabilities to potential adversaries. Meeting both challenges has been difficult for the study committee and staff, but every effort was made to respond to the stated need of the Technology Warning Division of the Defense Intelligence Agency (DIA) for maximum openness. I wish to express my appreciation to the members of the committee for their contributions to the preparation of this report.

  • In recent years, it has been getting much easier for anyone with a portable laptop to acquire software that can capture data crossing data networks. Many vendors have created user-friendly (read easy-to-use) packet decoders that can be installed with minimal cost. These decoders were intended for troubleshooting purposes but can easily become tools for malicious intent. Packet snooping by using these decoding programs has another effect: The technique can be used in impersonation attacks, which are discussed in the next section....

  • The BACnet protocol currently uses the connectionless User Datagram Protocol (UDP) for both Annex H and BACnet/IP communications. However, it is possible that Trans- mission Control Protocol (TCP) transport will be utilized for some service in the future, and so threats specific to TCP have been included. Even if TCP/IP is never used as part of the BACnet protocol, it still can be used to gain access to the building control system web servers, get access through the corporate firewall, and be used for denial of service attacks on the external network on which the BCS may depend.

  • The attack we propose aims at keystroke eavesdrop- ping. However, the privacy implication of disclosing the ESP/EIP information of other users’ process can be much more significant. With our techniques, such information can be conveniently converted to a system-call sequence that describes the behavior of the process, and some- times, the data it works on and the activities of its users.

  • The Threat Analyzer is used for the analysis of the alerts detected by your McAfee® Network Security Platform [formerly McAfee® IntruShield® ] Sensors as well as those processed by an integrated Host Intrusion Prevention Server. The Threat Analyzer works in conjunction with the policies applied to your McAfee® Network Security Sensor and Host Intrusion Prevention Sensors. For more information on policies, see IPS Configuration Guide.

  • When a transmission violating your enforced security policies is detected by a Sensor, the Sensor compiles information about the offending transmission and sends this “attack” data to the Manager in the form of an alert. Alert details include transmission data such as, source and destination IP addresses in the packet, as well as security analysis information (performed by the Sensor) such as attack type and severity. Alerts are backed up to the database and archived in order of occurrence.

  • Our contribution in this area is the creation of lightweight techniques for securing existing sensor network routing and data movement approaches, such as directed diffusion [5], spin [8] and data dissemination [9, 2]. We assume the computational capability and memory requirements typical of those provided by current generation of sensors. We note that in this work we make no attempt to counter the threat from a widespread denial of service attack against the RF layer.

  • Symantec has established some of the most comprehensive sources of Internet threat data in the world through the Symantec™ Global Intelligence Network. More than 240,000 sensors in over 200 countries and territories monitor attack activity through a combination of Symantec products and services such as Symantec DeepSight™ Threat Management System, Symantec Managed Security Services and Norton™ consumer products, as well as additional third-party data sources.

  • In this paper, we study the problem of complex event detection (CED) in a monitoring environment that consists of potentially a large number of distributed event sources (e.g., hardware sensors or software receptors). CED is becoming a fundamental capability in many domains including network and infrastructure security (e.g., denial of service attacks and intrusion detection [22]) and phenomenon and activity tracking (e.g., fire detection, storm detection, tracking suspicious behavior [23]).

  • Our goal is to provide privacy and integrity to the data, to authenticate the sender, to prevent replay attacks and to prevent traffic analysis; consequently, the entire communication is encrypted (with one exception which will be explained). All communications consist of a preamble, header and payload. The format of all communications (sensor nodes and the base station) consist of a preamble, header and payload. The preamble is empty if the communication originates from the base station and is directed to a sensor, otherwise it contains the address of the sending node.

  • The security administrator logged into the Locate web console and input the IP address and dates from the IDS log. Locate looked up the historical information for the time period in question. He was immediately presented with the name, location, and phone number of the user who was using the workstation to log into the mainframe. Within seconds the security administrator had the information he needed to make his report. The Locate Solution The security administrator logged into the Locate web console and input the IP address and dates from the IDS log.

  • Intrusion detection systems and vulnerability scanners provide an additional layer of network security.While firewalls permit or deny traffic based on source, destination, port, or other criteria, they do not actually analyze traffic for attacks or search the network for existing vulnerabilities. In addition, firewalls typically do not address the internal threat presented by “insiders.

  • The Symantec Global Internet Security Threat Report provides an annual overview and analysis of worldwide Internet threat activity, a review of known vulnerabilities, and highlights of malicious code. Trends in phishing and spam are also assessed, as are observed activities on underground economy servers. Previously presented every six months, this volume of the Symantec Global Internet Security Threat Report will alert readers to trends and impending threats that Symantec has observed for 2008.
