This Sunday at long last my first real server “Spike” died. Spike wasn’t really my server, but it was the first server that wasn’t just for my entertainment and I carried final responsibility for. Purchased in February 2001 it entered service as a shared hosting server for a not-for-profit in March 2001. In the 8 years and 1 month it ran the only real problem it had was a worn down CPU fan causing an overheated CPU, until Sunday morning at long last the primary harddisk died and it was retired from service.

With its demise I am truly saying goodbye to an era (or perhaps to a relic): Spike ran trusty old Windows NT4 SP6a with ColdFusion Enterprise 4.5.2. With it gone, the youngest production machine I have access to is a Windows 2003 system (7 years younger then NT4) with CF 7 (6 years younger then CF 4.5). Spike itself is replaced with a machine with Windows 2003 and CF 8.0.1. And the contrast between how it worked then and now it works now is quite profound. At least in the area of security configuration, CFML is sufficiently backward compatible to just drop it on the new server.

2001, the year Spike was configured, was just before the height of the ‘hackable internet’. A few months after it was taken into production we saw the release of Code Red, followed shortly by Nimda. At that time, a large part of the servers connected to internet was vulnerable to attacks. (Nowadays vulnerabilities are more of a client problem or arguably a user problem then s server problem.) And that showed itself in the way Spike was build. It took me several weeks to come up with a stable and secure configuration, with all sorts of weird constraints. To build Spike I followed the NSA guidelines for configuring a Windows NT system, which for instance meant I wasn’t supposed to install any graphical driver, because no driver was NSA certified. And the way I ended up running ColdFusion, with Sandbox Security configured to impersonate OS accounts, has once even earned me the comment from a Macromedia engineer to be the only one in the world with that configuration in production. But the result was there: even with the onslaught of Code Red and Nimda it took 7 months before there was a Windows patch that was applicable for the hardened configuration.

Contrast this with how I threw a new server online. Windows installation was a default installation, after which I had to add components instead of remove them. When installing IIS I had to add filetypes and extensions, instead of remove them. When configuring Sandbox Security for ColdFusion I could easily find anything I wanted on the subject, because there are dozens of people blogging about it. Obviously some of the ease of installing a new server is due to more experience on my side, but I think it is hard to deny that the “secure by default” mindset has made inroads.
