Trusted Computer Solutions has released version 2.0 of Security Blanket application, which also now includes an enterprise edition. Security Blanket is an automated system lockdown and security management tool for Linux. Security Blanket 2.0 enables system administrators to configure and enhance the security of their Linux platforms automatically by simplifying the hardening process that must be undertaken on a regular basis to meet security compliance requirements. Various security guidelines are included. Other key advancements in version 2.0 include the ability to manage local and remote Linux servers from a centralized management console and a Web-based interface for remote access. The application supports Red Hat Enterprise Linux versions 4 and 5, CentOS versions 4 and 5, and Oracle Enterprise Linux versions 4 and 5, and it runs on SELinux, enforcing the default targeted policy provided with the operating system.
The idea behind Tripwire Enterprise, upgraded recently to version 7.1, is to keep your IT expertise from walking out the door. The solution maximizes the use of IT expertise throughout an organization by capturing and replicating this knowledge across all IT systems. It ensures IT configuration integrity across the entire IT infrastructure and manages internal and external policies. Two key features include Golden Policies and Remediation Advisor. Golden Policies capture and replicate gold configurations and act like a “consultant in a box” that maximize the value of IT experts by replicating their IP (optimal configuration settings) across the IT infrastructure. In addition, Golden Policies help ensure IT personnel are proactively made aware of any configuration drift. The Remediation Advisor functionality provides step-by-step remediation, based on a wide variety of external IT resources, keeping staff from hours of research and reducing the time and effort needed to remediate problems.
In a move to help device manufacturers create novel mobile services of interest to large consumer audiences, Ixonos has developed a television reception solution for its Linux-based mobile platform. The solution enables reception of, among others, DVB-T and DVB-H transmissions and also can repeat them over a local area network. The video player used for TV reception also is the multimedia player for the entire platform and is based on the open-source MPlayer. Ixonos claims to be among the first companies to bring DVB-H reception to a Linux-based smartphone. The latest H.264 and AAC technologies are used as video and audio codecs.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
