Solaris Hardening

Never ever assume that some prepackaged script

Admin Horror Stories

Hardening scripts are perfect way to destroy any server, far more effective then hackers ;-). They should be used with the extreme caution. Historically Unix was from the beginning and justifiably, criticized for being a difficult system that is hard to secure. Among typical problems one can list:

Although network scanning is more fashionable, internal scanning is much more powerful and reliable. It also more mature and has a rich history. Unfortunately internal scanning and auditing is an often overlooked portion of system administration. Most sites do not utilize the auditing functionality of their systems (for example very few system administrators know about existence of such tools as pwck, grpck, aset on Solaris), etc.

The purpose of internal audit is simple: to identify potential vulnerabilities in systems. It's often a checkout  stage of hardening of the OS. It's much safer practice then automatic hardening using semi-baked scripts. See Solaris hardening page for more details.

Most early tools were distributed under liberal licenses that permit you  modify and  enhance them yourself before use. Titan and COPS are nice examples of  the Unix shell programming culture. I am convinced that  Titan, Cops and Tiger can be used for studying shell programming in universities.

 Solaris[tm] Security Toolkit is Sun supported set of scripts for hardening Solaris. The current version of the Solaris Security Toolkit is 4.2 Supports Solaris 2.5.1-2.10 on both Intel and Solaris. The JASS development team includes Alex Noordergraaf ([email protected]) and Glenn Brunette ([email protected]). Undo was implemented by Dina Kurktchi ([email protected]). It looks like the toolkit is used internally in Sun. Release 4.0.1 provides some enchancements such as:

but generally scripts are badly written and have a weak architecture (essentially, no architecture at all). JASS does not represent any progress in comparison with Titan and ACET. For more information see my Slightly Skeptical JASS Notes.

The Solaris Security Toolkit 4.2 release is fully supported as part of Solaris Software Support Service Plans or the SunSpectrum(SM) Service Plan contract.

The Sun BluePrints OnLine program includes four supporting documents for the Solaris Security Toolkit.

  1. Deploying the Solaris Operating Environment Using a Solaris Security Toolkit CD," September 2003, by Steven Spadaccini
    This article describes how to construct a bootable Solaris Security Toolkit software CD.
  2. The Solaris Security Toolkit -- Quick Start: Updated for Toolkit version 0.3
    This article provides an administrator with the information critical to getting the Solaris Security Toolkit installed and running as quickly as possible. The article does not include the details covered in the "Installation, Configuration, and Usage Guide" or "Internals" articles.
  3. The Solaris Security Toolkit -- Release Notes: Updated for Toolkit version 0.3
    This article provides toolkit users with a discussion of the new features, enhancements, and changes included in version 0.3 of the Solaris Security Toolkit.
  4. The Solaris Security Toolkit (JASS)," June 2001, by Alex Noordergraaf and Glenn Brunette
    Information regarding the Solaris Security Tookit and its associated articles is now contained on a dedicated page. These articles describe the toolkit in detail:  
  5. The Solaris Security Toolkit -- Installation, Configuration, and Usage Guide: Updated for Toolkit version 0.3
    This article focuses on the configuration and installation information of the Solaris Security Toolkit. It provides a more in-depth discussion of the installation, configuration, and usage options available in the toolkit than in the Sun BluePrints OnLine article titled "Solaris Security Toolkit -- Quick Start Guide."
  6. The Solaris Security Toolkit -- Internals: Updated for Toolkit version 0.3
    This article focuses on the internals of the toolkit, and includes discussions on each directory, file, and script included with the toolkit source. These components are reviewed in order to provide the reader with a detailed understanding of how the different toolkit components function and interact.
