What's Good for Security is Good for Operations: Why Configuration Assessment Followed by Change Auditing is Key to Operational Stability 2008-09-11 Tripwire

Network administrators and IT managers know that the ramifications of one small change to a company's critical servers or network devices--such as routers, switches, and firewalls--depend on whether the change is desired or not. Without a way to know when change occurs and whether it's desired, not desired, accidental, benign, malicious, intentional, or originating from inside or outside, IT teams have few options for preventing negative consequences and minimizing damage. Configuration audit and control solutions give organizations greater control over service-affecting changes and provide the foundation of a layered security strategy. Tripwire configuration audit and control software monitors key files and configurations of servers, desktops, network devices, directory servers and more, detecting externally- and internally-originating changes, alerting IT staff, and providing detailed reports for rapid restoration of systems to a known good state.

File Integrity Monitoring: Secure Your Virtual and Physical IT Environments 2008-09-10 Tripwire

Looking for a File Integrity Monitoring Solution? With the numerous servers, devices and applications organizations rely on to support their everyday business, outages and security breaches due to poor IT configurations are unacceptable. In addition, many organizations must now prove compliance with standards like PCI DSS--designed to protect systems and sensitive data. File integrity monitoring solutions minimize security risk resulting from undesirable configuration change by monitoring, detecting, and reconciling changes to key files throughout the virtual and physical IT infrastructures.

Learn how file integrity monitoring solutions work and the capabilities you should expect your solution to have. Then review a detailed checklist you should complete before purchasing your solution. Finally, discover how Tripwire Enterprise effectively combines file integrity monitoring with configuration assessment-a single configuration control solution that proactively assesses and monitors the IT infrastructure and enables organizations to achieve and maintain compliance with standards and regulations.

A Scalable, Commodity Data Center Network Architecture 2008-08-22 Association for Computing Machinery

Today's data centers may contain tens of thousands of computers with significant aggregate bandwidth requirements. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP switches/routers, resulting topologies may only support 50% of the aggregate bandwidth available at the edge of the network, while still incurring tremendous cost. Non-uniform bandwidth among data center nodes complicates application design and limits overall system performance. This paper shows how to leverage largely commodity Ethernet switches to support the full aggregate bandwidth of clusters consisting of tens of thousands of elements.

DyNeF: Host-Privilege-Based Dynamic Network Firewall for Grid Environment 2008-08-01 World Academy of Science, Engineering and Technology

Security in grid environment is still a major challenge considering the possible security breaches that can occur in a multi-institutional resource sharing infrastructure. Unlike the Internet, grid is a dynamic collection of resources, users and services that poses increased security challenges to the research community. This paper address the need for a dynamic network firewall in grid environment for supporting its dynamic nature whereby, protecting it from network intrusions. In this vision, it brings out the need for host-based access privileges and the importance of these privileges in addressing security challenges imposed by the grid environment.

Cisco IOS Embedded Event Manager Version 2.4 Expanded Capabilities and New Interfaces 2008-08-01 Cisco Systems

Cisco IOS Embedded Event Manager (EEM) is a powerful tool integrated with Cisco IOS Software for monitoring and management from within the device itself. EEM offers the ability to monitor software subsystems and take informational, corrective, or any desired action when the monitored events occur or when a threshold is reached. Capturing the state of the router during such situations can be invaluable in taking immediate recovery actions and gathering information to perform root-cause analysis. Network availability is also improved if automatic recovery actions are performed without the need to fully reboot the routing device.

Control System for Internet Bandwidth Based on Java Technology 2008-07-07 Journal of Theoretical and Applied Information Technology

This paper presents a Java-based real-time Internet access estimation tool for Quality of Service (QoS) in Internet accesses for Multimedia applications (JEQoSIM). It is specially aimed for real-time multimedia applications which use the User Datagram Protocol (UDP). The system is capable of estimating access capacity, available bandwidth and delay as the critical end-to-end QoS parameters for this kind of applications. The algorithm used for QoS estimations is one-way, and is based on the packet train technique. Real-time QoS estimation elements are distributed among a central server and the Internet end user. The central server contains a UDP packet bursts server and a web server that hosts the Java applet that implements the UDP packet bursts client.

A Two-Tiered On-Line Server-Side Bandwidth Reservation Framework for the Real-Time Delivery of Multiple Video Streams 2008-07-01 Boston University

The advent of virtualization and cloud computing technologies necessitates the development of effective mechanisms for the estimation and reservation of resources needed by content providers to deliver large numbers of Video-On-Demand (VOD) streams through the cloud. Unfortunately, capacity planning for the QoS-constrained delivery of a large number of VOD streams is inherently difficult as VBR encoding schemes exhibit significant bandwidth variability. This paper presents a novel resource management scheme to make such allocation decisions using a mixture of per-stream reservations and an aggregate reservation, shared across all streams to accommodate peak demands.

Choosing the Right CMDB: Smart Considerations for Strategic Decision Makers 2008-06-25 ASG Software Solutions

A forward-looking Configuaration Management Database (CMDB) does more than keep an organization's IT operations running. It draws clear connections between IT components and business services, which is the core of Business Service Management (BSM). But even more critical than the CMDB's ability to support business as it is now, is the question of how well it will drive business innovation in the future. If a CMDB is right for modern business, it should go beyond BSM.

ASG Service Dependency Mapping: Making the Link between IT and the Business 2008-07-29 ASG Software Solutions

Aligning IT and business perspectives requires the ability to create links between configuration information in an enterprise Configuration Management Database (CMDB) and the business service as experienced by the user. Service Dependency Mapping (SDM) products automate the process of creating and maintaining these links.

This Enterprise Management Associates (EMA) white paper examines how IT organizations can transition to a more service-focused approach to managing business applications, and how these leading-edge management solutions support this transition. This new approach is business service-driven instead of infrastructure-driven and enables IT organizations to manage the service in context to technology. In doing so, it brings IT into much closer overall alignment with the business.
