Unix Services

Central System Administration

Unix Services provides central system administration for all Unix and Linux based general purpose computing resources at BNL.  The program implementation is broken up into four major components.

Purpose

Centralized administration provides the ability to enforce DOE mandates across the enterprise.  Further, it improves our overall security posture and allows users to receive faster response to support requests.

Implementation

Top of PageConfiguration Management

Through the CFEngine program, Unix Services provides automatic centralized configuration management.  This is how Unix Services applies necessary baseline configurations.

ITD Unix services maintains patches and security resources for its supported operating systems through services such as the Red Hat Network for Red Hat systems, and through software and operating system mirrors.

Top of PageCentralized Authentication

Unix and Linux systems at BNL authenticate against the Microsoft Active Directory.  This provides a single-sign-on capabilities, allowing users to have a fewer passwords to remember.

Top of PageAuditing

The Ordo based host scanning tool required for running a Unix or Linux based operating system on the BNL intranet provides auditing of compliance and system configurations.

Also in Unix Service's tool kit, for those systems that request or require it, are system monitoring and file integrity scanners.

Top of PageGovernance

The Unix Services administration and configuration plans are not a "black box" approach.  Governance of the program is transparent.  The current version of the centralization documentation is always open available for review: Centralization_Document-current.doc.
