Paranoid Penguin - Building a Secure Squid Web Proxy, Part III
Tighten the controls on your Squid Web proxy.
Setting ACLs, running Squid with nonroot privileges most or all of the time and running Squid in a chroot jail constitute the bulk of Squid's built-in security features. But, these are not the only things you can do to use Squid to enhance your network and end-user systems' security.
Next time, I'll show you how to use add-on tools such as SquidGuard to increase Squid's intelligence in how it evaluates clients' requests and servers' replies. I'll also address (if not next time then in a subsequent column) some of the finer points of proxying TLS/SSL-encrypted sessions. Until then, be safe!

Fabric-Based Computing Enables Optimized Hyperscale Data Centers
Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy
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.

Free Webinar: Linux Backup and Recovery
Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.
In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
