Storage Cluster: A Challenge to LJ Staff and Readers

By Chad Columbus 

For a few years I have been trying to create a "distributed cluster storage system" (see below) on standard Linux hardware. I have been unsuccessful. I have looked into buying one and they do exist, but are so expensive I can't afford one. They also are designed for much larger enterprises and have tons of features I don't want or need. I am hoping the Linux community can help me create this low cost "distributed cluster storage system" which I think other small businesses could use. Please help me solve this so we can publish the solution to the open source community. more>>

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.
