Hands On Labs: Installing Solaris 10 on VirtualBox

The prolific and well-traveled Brian Leonard, author of the popular Observatory blog, has just finished creating a new hands-on lab:

HOL: Intall Solaris 10 on VirtualBox

This lab is a prerequisite to several upcoming labs. It installs a Solaris 10 10/09 appliance image on Oracle VM VirtualBox on your system. Instructions and prerequisites are provided for Windows, MacOS, Solaris, and Linux. Use this and future hands-on lab to evaluate and become familiar with the operation of several Oracle Solaris technologies. You can find them under the Resources Pages heading in the right column of our Home Page (you might need to scroll down a bit).

You never know. One day it might save you from appearing outclassed by the common household objects of a rival species.

New In Solaris 10 9/10 (Update 9)

Don't just sit there waiting for something to happen, go find out what's new in the latest release of Oracle Solaris 10!

The Docs

The docs, as usual, are always a good place to start. This collection summarizes the major improvements and links to the full documentation that describes them in detail.


Hamburger Quick Summary of What's New

Because they get up earlier in the morning, the Hamburger MumbleSolaris User Group has a quick summary that you can print out and memorize in case the opportunity to impress your social inferiors ever presents itself.


Features and Benefits

A quick summary of each new feature in the 9/10 update and the benefits it provides to sysadmins or developers. To the point and surprisingly bereft of adjectives.

Keep an eye on the Front Page of OTN's Systems Admin and Developer Community throughout the day for more updates.

Great New Article on Oracle Solaris 10 Security


In "Using Oracle Solaris 10 to Overcome Security Challenges," Mark Thacker describes how Oracle Solaris 10 uses the principle of least privilege to reduce the vulnerabilities of applications that perform privileged operations as root.

"Over 65 discrete, fine-grained privileges are built into the kernel and user access space. The concept of privileges as implemented in Oracle Solaris 10 is extended throughout the operating system — even the built-in tools take these rights and privileges into account. Using this approach, administrators can grant new or existing applications only the appropriate privileges necessary to perform tasks. Many system components such as NFS, the Oracle Solaris Cryptographic Framework, IP Filter, file system mount commands, and more, are already configured to run with reduced privileges by default, with no configuration required by the administrator.

Mark goes on to provide clear explanations of how the following Solaris 10 security features work:

  • User Rights Management (role-based access control), which an administrator uses to limit access to administrative functions while providing access to specific operating functions.
  • Network Security and Encryption, which includes Secure-By-Default (one of those "Duh, why didn't I think of that" ideas), IP packet filtering firewall, an integreated cryptographic framework, and an arsenal of other tools that sysadmins can use to both keep out network intruders and comply with privacy regulations.
  • Minimized and Hardened OS, which reduces the size of the target for hackers by only installing basic features and securing them at the same time.
  • Containers and Trusted Extensions that enable sysadmins to isolate and protect applications and users in a virtualized environment.

This article is clear, easy to understand, and does a great job of explaining exactly how an admin can use the security tools of Solaris 10 to protect and certify an operating environment.  Includes a solid list of security resources.

I found the picture of the bull in this BBC story.
