Setting Up Virtual Security Zones in a Linux Cluster

The Distributed Security Infrastructure lets you create disjoint virtual security zones on a physical Linux cluster.

We have shown a practical solution for sharing a cluster securely among different applications belonging to different users. The DSI Project allows users to create disjoint security zones for each application in the cluster easily. Once DSI is installed on the cluster, the effort needed to create a new security zone for new applications scales down to setting appropriate ScIDs to binaries and including corresponding rules in the DSP file. Source code modification is not required and probably would be impossible anyway.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

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.
