New Products
The new Centrify Suite 2008 is an integrated family of Active Directory-based auditing, access control and identity management solutions for cross-platform environments. The applications also help address regulatory compliance, says its maker Centrify, by adhering to requirements from SOX, PCI, HIPAA, GLBA and FISMA. The Standard Edition contains two applications: DirectControl, which secures non-Microsoft platforms using the same authentication and Group Policy services found in a Windows environment, and DirectAuthorize, which provides centralized role-based entitlement management for fine-grained user access and privilege rights on UNIX and Linux systems. The Enterprise Edition adds DirectAudit, which offers auditing, logging and real-time monitoring of user activity on non-Microsoft systems. The Application Edition, meanwhile, is for organizations using Web/Java applications, databases or enterprise applications, such as SAP or PeopleSoft.
It appears that our constant pestering for Linux support on various devices is paying off. The latest manufacturer to announce Linux support is Primera Technology, maker of a range of disc publishers, which announced support for its Bravo II, BravoPro, Bravo XR and Bravo XRP CD/DVD/BD devices. Primera says that its full-featured Linux printer drivers can be integrated with open-source or commercially available disc-burning engines easily. The drivers can be downloaded from the firm's Web site.
StarOffice, the enterprise-oriented sibling of OpenOffice.org, has been upgraded to Version 9. This open-source office productivity suite contains the Writer word processor, Calc spreadsheet, Impress presentation, Base database and Draw drawing/graphics applications. StarOffice Version 9 adds features, such as Mozilla Thunderbird for e-mail and Lightning for calendaring, an enterprise migration tool and various extensions for blogging, communicating, wiki publishing and PDF editing. Further, like OpenOffice.org 3.0, StarOffice 9 can read and write Microsoft Office .docx files. A range of support models are available; indemnification against intellectual property lawsuits is included in each. StarOffice comes in Linux, Solaris and Windows flavors.
The new Varnish 2.0 from Linpro is an open-source reverse-Web accelerator for high-content Web sites that was designed from the ground up for incoming traffic and not as a client-side proxy or origin server. Varnish temporarily stores the most frequently requested pages in cache memory and offers tools for identifying which pages should and should not be cached, and if they are cached, when to delete them and present fresh content. The result, says Linpro, is a 90% reduction in server requirements. Varnish 2.0 offers new features like improved compression, expanded support for filtering Web content for caching, ESI language support, tighter integration with CMS solutions, load-balancing support, better scaling and improved accelerator tuning. Varnish runs on Linux, Solaris and FreeBSD.
The new Hot Copy from R1Soft is a Linux command-line utility that takes on-line snapshots of disks or volumes on a Linux server. Because Hot Copy does not use LVM, it can work on any Linux system and with any block device. Some sample applications are turning legacy backups into on-line ones, creating a copy before running or testing dangerous scripts and commands (for example, rm -Rf), running fsck safely while the filesystem is mounted and viewing changes on systems. Features include instant, non-interrupting point-in-time snapshots of any block device, point-in-time snapshots with the system in a totally consistent state, copy-on-write snapshots, writeable snapshots and no need for dedicated snapshot devices or storage.
TotalView Technologies recently upgraded to Version 8.6 its TotalView tool for source code analysis and memory error detection. Most notably, this latest release adds TVScript, a new troubleshooting utility offering a streamlined mechanism for automated and unattended debugging. In addition, the new SSH-based Remote Display Client allows users to set up and operate securely an interactive graphical debugging session on remote systems located anywhere. The Remote Display Client is available for 32- and 64-bit Linux and Windows.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
