6.3 Locally Authored Linux Security DocumentIndex

Mike Gifford runs OpenConcept Consulting here in town: “Open source web development for social change”. He works with Drupal, an open source web content management system (CMS).

He wrote:

We’ve been working on a best practices document for Drupal security that is geared specifically at government clients. […] We wrote this for a federal government department in town that had their site compromised earlier in the year. Figured it was a good time to write up a general document to help guide folks in the public sector. Security is certainly a complex issue, and most government departments just don’t seem to get it. For instance CSEC provides security information for Windows 2003, but not Windows 2008.

We are releasing this document because we believe that most government departments simply do not have the resources to put into properly setting up and maintaining the security of their servers. Our hope is that we will be able to build a community of people behind this process who can help build on and maintain a set of best practices. I’m also hoping that it helps to reach up into management a bit and be more approachable for folks who already with IT security.

I do hope that folks […] heard the recent court case with the 12 year old boy who is on trial for hacking into government computer systems in 3 different jurisdictions. To some extent that’s a reflection the rise of hacker culture on the Internet, but it should also be an indication of how far government security practices have fallen short. If a kid can hack away at government sites for fun, and get away with this much information, what are more politically or crime motivated hackers capable of? There is far too much security theatre and not enough collaboration within government about how to raise the lowest common denominator for security. I’ve blogged about this here:

http://openconcept.ca/blog/mgifford/when-even-our-kids-can-hack-government-site

We’ve released the initial security guide here for review here (we are asking for people to submit their name & email so that we can track who is making use of this PDF):

http://openconcept.ca/drupal-security-guide

We’d like to get feedback on this document, and our hope is that this starts an open conversation about security best practices. I would like to thank the people who have contributed to this document, but generally I have decided what is or is not listed in this release. There will be errors that I likely introduced and they will be addressed as they are raised.

There’s a GoogleDoc too for folks who are interested in adding comments directly to that version of the document.
